Make-Up For Men: John Varvatos Concealer

FabSugar — Tue, 24 Oct 2006 13:40:48 -0700

Yes, man make-up is here; I've seen it with my very own eyes. I think this idea is brilliant. Why should a man dealing with a huge red pimple or a poor night's sleep have to announce it to the world just because he's a man? Men deserve to have a few tricks in their grooming arsenals, too.

Now, thanks to John Varvatos Skin Care, they do. The John Varvatos Skin Concealer is a fantastic pore-refining and mattifying concealer. Formulated especially for men, it helps cover up dark circles, red areas, broken capillaries, and pimples. When I tried the foundation on my hand, I couldn't believe how lightweight and smooth it was. The packaging reminds me of Nars The Multiple Stick. The tube has a similar rubbery skin-like feel, and the concealer is easy to use with its wide base and silky soft application. Buy it in three shades here for $26.

Anxiety disorders

FitSugar — Wed, 08 Oct 2008 17:34:56 -0700

HEALTH GUIDE REFERENCE FROM A.D.A.M

Highlights

Drug Approval

In 2007, duloxetine (Cymbalta) was approved for treatment of generalized anxiety disorder. Duloxetine is a dual inhibitor antidepressant.

Anxiety Disorders Under-Recognized and Under-Treated

About 41% of patients with an anxiety disorder do not receive any treatment, indicates a 2007 study in the Annals of Internal Medicine. Anxiety disorders can interfere with daily functioning, and problems worsen when people have more than one type of anxiety disorder. The study’s researchers recommend that screening for anxiety become a regular part of office visits in the same way that primary care doctors screen patients for depression.

Antidepressants and Children

The benefits of antidepressants for treating pediatric anxiety disorders appear to outweigh the risks for suicide, according to a 2007 review in the Journal of the American Medical Association. Researchers also found that antidepressants did not work as well for treating obsessive compulsive disorder compared to other types of anxiety disorders. This review was the largest to date of antidepressant use in children and adolescents. Most doctors recommend cognitive behavioral therapy as the first treatment approach for childhood anxiety disorders.

Psychological Therapies for Post-Traumatic Stress Disorder

Specially designed psychotherapies -- such as trauma-focused cognitive behavioral therapy, eye movement desensitization and reprocessing, and stress management -- are the most effective therapies for patients with post-traumatic stress disorder, according to a 2007 review in the Cochrane Database.

Introduction

Fear and stress reactions are essential for human survival. They enable people to pursue important goals and to respond appropriately to danger. In a healthy individual, the stress response (fight, fright, or flight) is provoked by a genuine threat or challenge and is used as a spur for appropriate action.

An anxiety disorder, however, involves an excessive or inappropriate state of arousal characterized by feelings of apprehension, uncertainty, or fear. The word is derived from the Latin, angere, which means to choke or strangle. The anxiety response is often not attributable to a real threat. Nevertheless it can still paralyze the individual into inaction or withdrawal. An anxiety disorder persists, while a healthy response to a threat resolves, once the threat is removed.

Anxiety disorders have been classified according to the severity and duration of their symptoms and specific behavioral characteristics. Categories include:

Generalized anxiety disorder (GAD), which is long lasting and low-grade
Panic disorder, which has more dramatic symptoms
Phobias
Obsessive-compulsive disorder (OCD)
Post-traumatic stress disorder (PTSD)
Separation anxiety disorder (which is almost always seen in children)

GAD and panic disorder are the most common. Anxiety disorders are usually caused by a combination of psychological, physical, and genetic factors, and treatment is, in general, very effective.

Generalized anxiety disorder (GAD) is the most common anxiety disorder. It affects about 5% of Americans over the course of their lifetimes. It is characterized by the following:

A more-or-less constant state of worry and anxiety, which is out of proportion to the level of actual stress or threat in their lives.
This state occurs on most days for more than 6 months despite the lack of an obvious or specific stressor. (It worsens with stress, however.)
It is very difficult to control worry. For a clear diagnosis of GAD, the specific worries should be differentiated from those that would define other anxiety disorders, such as fear of panic attacks or appearing in public. Moreover, they are not obsessive like people with obsessive-compulsive disorder. (It should be noted, however, that over half of those with GAD also have another anxiety disorder or depression.)
Patients with anxiety may experience physical symptoms (such as gastrointestinal complaints) in addition to, or even in place of, mental worries. (This latter case may be more common in people from non-Western cultures such as those with Asian backgrounds.)
People with GAD tend to be unsure of themselves, overly perfectionist, and conforming.

Given these conditions, a diagnosis of GAD is confirmed if three or more of the following symptoms are present (only one for children) on most days for 6 months:

Being on edge or very restless
Feeling tired
Having difficulty with concentration
Being irritable
Having muscle tension
Experiencing disturbed sleep

Symptoms should cause significant distress and impair normal functioning and not be due to a medical condition, another mood disorder, or psychosis. It should be noted that pure GAD is uncommon. It typically occurs with other mood disorders (anxiety or depression) or substance use.

Panic disorder is characterized by periodic attacks of anxiety or terror (panic attacks). They usually last 15 - 30 minutes, although residual effects can persist much longer. The frequency and severity of acute states of anxiety determine the diagnosis. (It should be noted that panic attacks can occur in nearly every anxiety disorder, not just panic disorder. In other anxiety disorders, however, there is always a cue or specific trigger for the attack.) A diagnosis of panic disorder is made under the following conditions:

A person experiences at least two recurrent, unexpected panic attacks.
For at least a month following the attacks, the person fears that another will occur.

Symptoms of a Panic Attack. During a panic attack a person feels intense fear or discomfort with at least four or more of the following symptoms:

Rapid heart beat
Sweating
Shakiness
Shortness of breath
A choking feeling or a feeling of being smothered
Dizziness
Nausea
Feelings of unreality
Numbness
Either hot flashes or chills
Chest pain
A fear of dying
A fear of going insane

Women may be more likely than men to experience shortness of breath, nausea, and feelings of being smothered. More men than women have sweating and abdominal pain. Panic attacks that include only one or two symptoms, such as dizziness and heart pounding, are known as limited-symptom attacks. These may be either residual symptoms after a major panic attack or precursors to full-blown attacks. (It should be noted that panic attacks can also accompany other anxiety disorders, such as phobias and post-traumatic stress disorder. In such cases, however, additional characteristics differentiate these disorders from panic disorder.)

Frequency of Panic Attacks. Frequency of attacks can vary widely. Some people have frequent attacks (for example, every week) that occur for months; others may have clusters of daily attacks followed by weeks or months of remission.

Triggers of Panic Attacks. Panic attacks may occur spontaneously or in response to a particular situation. Recalling or re-experiencing even harmless circumstances surrounding an original attack may trigger subsequent panic attacks.

Phobias, manifested by overwhelming and irrational fears, are common. In most cases, people can avoid or at least endure phobic situations, but in some cases, as with agoraphobia, the anxiety associated with the feared object or situation can be incapacitating.

Agoraphobia. Agoraphobia has been somewhat misleadingly described as fear of open spaces, the term having been derived from the Greek word agora, meaning outdoor marketplace. In its severest form, agoraphobia is characterized by a paralyzing terror of being in places or situations from which the patient feels there is neither escape nor accessible help in case of an attack. (One patient described the terror of going outside as opening a door onto a landscape filled with snakes.) Consequently, people with agoraphobia confine themselves to places in which they feel safe, usually at home. The patient with agoraphobia often makes complicated plans in order to avoid confronting feared situations and places.

Social Phobia. Social phobia, also known as social anxiety disorder, is the fear of being publicly scrutinized and humiliated and is manifested by extreme shyness and discomfort in social settings. This phobia often leads people to avoid social situations and is not due to a physical or mental problem (such as stuttering, acne, or personality disorders). The incidence of social phobia is about 13% and has been termed "the neglected anxiety disorder" because it is often not properly diagnosed.

The associated symptoms vary in intensity, ranging from mild and tolerable anxiety to a full-blown panic attack. (Unlike a panic attack, however, social phobia is always directly related to a social situation.) Symptoms include sweating, shortness of breath, pounding heart, dry mouth, and tremor.

The disorder may be further categorized as generalized or specific social phobia:

Generalized social phobia is the fear of being humiliated in front of other people during nearly all social situations. People with this subtype are the most socially impaired and also the most likely to seek treatment.
Specific social phobia usually involves a phobic response to a specific event. Performance anxiety ("stage fright") is the most common specific social phobia and occurs when a person must perform in public. These patients usually feel comfortable in informal social situations.

Children with social anxiety develop symptoms in settings that include their peers, not just adults, and they may include tantrums, blushing, or not being able to speak to unfamiliar people. These children should be able to have normal social relationships with familiar people, however.

Specific Phobias. Specific phobias (formerly simple phobias) are an irrational fear of specific objects or situations. Specific phobias are among the most common medical disorders. Most cases are mild and not significant enough to require treatment.

The most common phobias are fear of animals (usually spiders, snakes, or mice), flying (pterygophobia), heights (acrophobia), water, injections, public transportation, confined spaces (claustrophobia), dentists (odontiatophobia), storms, tunnels, and bridges.

When confronting the object or situation, the phobic person experiences panicky feelings, sweating, avoidance behavior, difficulty breathing, and a rapid heartbeat. Most phobic adults are aware of the irrationality of their fear, and many endure intense anxiety rather than disclose their disorder.

Obsessive-compulsive disorder (OCD) has been described as hiccups of the mind. OCD is time-consuming, distressing, and can disrupt normal functioning. Much research suggests that a critical feature in this disorder is an overinflated sense of responsibility, in which the patient's thoughts center around possible dangers and an urgent need to do something about it.

Obsessions are recurrent or persistent mental images, thoughts, or ideas. The obsessive thoughts or images can range from mundane worries about whether one has locked a door to bizarre and frightening fantasies of behaving violently toward a loved one.
Compulsive behaviors are repetitive, rigid, and self-directed routines that are intended to prevent the manifestation of an associated obsession. Such compulsive acts might include repetitive checking for locked doors or unlit stove burners or calls to loved ones at frequent intervals to be sure they are safe. Some people are compelled to wash their hands every few minutes or to spend inordinate amounts of time cleaning their surroundings in order to subdue the fear of contagion.

Over half of OCD-sufferers have obsessive thoughts without the ritualistic compulsive behavior. Although individuals recognize that the obsessive thoughts and ritualized behavior patterns are senseless and excessive, they cannot stop them in spite of strenuous efforts to ignore or suppress the thoughts or actions. OCD often accompanies depression or other anxiety disorders. There is some evidence that the symptoms improve over time and that nearly half will eventually recover completely or have only minor symptoms.

Symptoms in children may be mistaken for behavioral problems (taking too long to do homework because of perfectionism, refusing to perform a chore because of fear of germs). Children do not usually recognize that their obsessions or compulsions are excessive.

Associated Obsessive Disorders. Certain other disorders that may be part of, or strongly associated with, the OCD spectrum include the following:

Body dysmorphic disorder (BDD). In BDD, people are obsessed with the belief that they are ugly, or part of their body is abnormally shaped.
Hypochondriasis. People who have hypochondiasis have an excessive fear of having a serious disease.
Anorexia nervosa. OCD frequently accompanies this eating disorder, where the compulsive behavior focuses on food restriction and thinness.
Trichotillomania. People with trichotillomania continually pull their hair, leaving bald patches.
Tourette syndrome. Symptoms of Tourette syndrome include jerky movements, tics, and uncontrollably uttering obscene words.

Obsessive-Compulsive Personality. OCD should not be confused with obsessive-compulsive personality, which defines certain character traits (being a perfectionist, excessively conscientious, morally rigid, or preoccupied with rules and order). These traits do not necessarily occur in people with obsessive-compulsive disorder.

Post-traumatic stress disorder (PTSD) is a severe, persistent emotional reaction to a traumatic event that severely impairs one’s life. It is classified as an anxiety disorder because of its symptoms. Not every traumatic event leads to PTSD, however. There are two criteria that must be present to qualify for a diagnosis of PTSD:

The patient must have directly experienced, witnessed, or learned of a life-threatening or seriously injurious event.
The patients' response is intense fear, helplessness, or horror. Children may behave with agitation or with disorganized behavior.

Triggering Events. PTSD is triggered by violent or traumatic events that are usually outside the normal range of human experience. There is some evidence that events most likely to trigger PTSD are those that involve deliberate and destructive behavior (murder, rape) and those that are prolonged or physically challenging. Such events include, but are not limited to, experiencing or witnessing sexual assaults, accidents, military combat, natural disasters (such as earthquakes), or unexpected deaths of loved ones. PTSD may also occur in people who have serious illness and receive aggressive treatments or who have close family members or friends with such conditions.

Symptoms of PTSD. There are three basic sets of symptoms associated with PTSD. They may begin immediately after the event or can develop up to a year afterward:

Re-experiencing. In such cases, patients persistently re-experience the trauma in at least one of the following ways: in recurrent images, thoughts, flashbacks, dreams, or feelings of distress at situations that remind them of the traumatic event. Children may engage in play, in which traumatic events are enacted repeatedly.
Avoidance. Patients may avoid reminders of the event, such as thoughts, people, or any other factors that trigger recollection. They tend to have an emotional numbness, a sense of being in a daze or of losing contact with their own identity or even external reality. They may be unable to remember important aspects of the event.
Increased Arousal. This includes symptoms of anxiety or heightened awareness of danger (sleeplessness, irritability, being easily startled, or becoming overly vigilant to unknown dangers).

To further qualify for a diagnosis of PTSD, patients must have at least one symptom in the re-experiencing category, three avoidance symptoms, and two arousal symptoms. Symptoms are chronic (3 months or more). Symptoms should also not be associated with alcohol, medications, or drugs and should not be intensifications of a pre-existing psychological disorder.

Acute Stress Disorder. Experts have identified a syndrome called acute stress disorder, in which symptoms of PTSD occur within 2 days to 4 weeks after the traumatic event. Acute stress disorder can accurately identify up to 94% of victims at risk for PTSD. Between 50 - 80% of these patients actually develop the more chronic and serious disorder. In other words, it is very sensitive for identification of those at highest danger for PTSD but less successful in determining specifically who will or will not recover emotionally.

Long-Term Outlook. The long-term impact of a traumatic event is uncertain. In one study of people who survived a mass killing spree in Texas, less than half of those who suffered PTSD (28% of all survivors) had recovered after a year. In another study, PTSD became chronic in 46% of the subjects. In fact, PTSD may cause physical changes in the brain, and in some cases the disorder can last a lifetime.

Separation anxiety disorder almost always occurs in children. It is suspected in children who are excessively anxious about separation from important family members or from home. For a diagnosis of separation anxiety disorder, the child should also exhibit at least three of the following symptoms for at least 4 weeks:

Extreme distress from either anticipating or actually being away from home or being separated from a parent or other loved one
Extreme worry about losing or about possible harm befalling a loved one
Intense worry about getting lost, being kidnapped, or otherwise separated from loved ones
Frequent refusal to go to school or to sleep away from home
Physical symptoms such as headache, stomach ache, or even vomiting, when faced with separation from loved ones

Separation anxiety often disappears as the child grows older, but if not addressed, it may lead to panic disorder, agoraphobia, or combinations of anxiety disorders.

Studies suggest that an imbalance of certain substances called neurotransmitters (chemical messengers in the brain) may contribute to anxiety disorders. The neurotransmitters targeted in anxiety disorders are gamma-aminobutyric acid (GABA), serotonin, dopamine, and epinephrine. Serotonin appears to be specifically important in feelings of well-being, and deficiencies are highly related to anxiety and depression.

Examples of study findings on some neurotransmitters are:

Abnormalities in the neurotransmitters gamma-aminobutyric acid (GABA) and serotonin may have a particular role in susceptibility to generalized anxiety disorder. GABA helps prevent nerve cells from over-firing and serotonin is a brain chemical important in feelings of well-being.
Serotonin is a major player in OCD.
Changes in serotonin and dopamine have been observed in social phobia.
People with post-traumatic stress disorder have abnormalities in stress hormones (cortisol) and neurotransmitters associated with stress (epinephrine and norepinephrine). Such imbalances could account for the higher anxiety levels and a tendency to startle easily after a threat in people with PTSD.
Corticotropin-releasing factor (CRF), which is believed to be a stress hormone and a neurotransmitter, is thought to be involved in depression and anxiety by causing changes in serotonin levels.

The best way to envision the brain's response to a threat is to imagine a primal situation, such as being chased by a bear.

The Brain's Response to Acute Stress. In response to seeing the bear, a part of the brain called the hypothalamic-pituitary-adrenal (HPA) system is activated.

Release of Steroid Hormones and the Stress Hormone Cortisol. The HPA systems trigger the production and release of steroid hormones (glucocorticoids), including the primary stress hormone cortisol. Cortisol is very important in marshaling systems throughout the body (including the heart, lungs, circulation, metabolism, immune systems, and skin) to deal quickly with the bear.

Release of Catecholamines and Activation of the Amygdala. The HPA system also releases certain neurotransmitters (chemical messengers) called catecholamines, particularly those known as dopamine, norepinephrine, and epinephrine (also called adrenaline).

Catecholamines activate the amygdala, a small structure deep in the brain, which regulates control of major emotional activities, including anxiety, depression, aggression, and affection. In fact, the amygdala is sometimes known as the "fear" center.

Effects on Long- and Short-Term Memory. During the stressful event, catecholamines also suppress activity in areas at the front of the brain concerned with short-term memory, concentration, inhibition, and rational thought. This sequence of mental events allows a person to react quickly to the bear, either to fight or to flee from it. (It also hinders the ability to handle complex social or intellectual tasks and behaviors during that time.)

On the other hand, neurotransmitters at the same time signal the hippocampus (a nearby area in the brain) to store the emotionally loaded experience in long-term memory. In primitive times, this brain action would have been essential for survival, since long-lasting memories of dangerous stimuli (the large bear) would be critical for avoiding such threats in the future.

Response by the Heart, Lungs, and Circulation to Acute Stress. The stress response also affects the heart, lungs, and circulation:

As the bear comes closer, the heart rate and blood pressure increase instantaneously.
Breathing becomes rapid and the lungs take in more oxygen.
The spleen discharges red and white blood cells, allowing the blood to transport more oxygen throughout the body. Blood flow may actually increase 300 - 400%, priming the muscles, lungs, and brain for added demands.

The Immune System's Response to Acute Stress. The effect on the immune system from confrontation with the bear is similar to marshaling a defensive line of soldiers to potentially critical areas. The steroid hormones dampen parts of the immune system, so that specific infection fighters (including important white blood cells) or other immune molecules can be redistributed. These immune-boosting troops are sent to the body’s front lines where injury or infection is most likely, such as the skin, the bone marrow, and the lymph nodes.

The Acute Response in the Mouth and Throat. As the bear gets closer, fluids are diverted from nonessential locations, including the mouth. This causes dryness and difficulty in talking. In addition, stress can cause spasms of the throat muscles, making it difficult to swallow.

The Skin's Response to Acute Stress. The stress effect diverts blood flow away from the skin to support the heart and muscle tissues. (This also reduces blood loss in the event that the bear catches up.) The physical effect is a cool, clammy, sweaty skin. The scalp also tightens so that the hair seems to stand up.

Metabolic Response to Acute Stress. Stress shuts down digestive activity, a nonessential body function during short-term periods of physical exertion or crisis.

The Relaxation Response: the Resolution of Acute Stress. Once the threat has passed and the effect has not been harmful (the bear has not eaten or seriously wounded the human), the stress hormones return to normal. This is known as the relaxation response. In turn, the body's systems also normalize.

Causes

A person's genetics, biochemistry, environment, history, and psychological profile all seem to contribute to the development of anxiety disorders. Most people with these disorders seem to have a biological vulnerability to stress, making them more susceptible to environmental stimuli than the rest of the population.

Abnormalities in the Brain. Scientists are using imaging techniques, particularly magnetic resonance imaging (MRI), to identify different areas of the brain associated with anxiety responses.

An MRI (magnetic resonance imaging) of the brain creates a detailed image of the complex structures in the brain. An MRI can give a three-dimensional depiction of the brain, making location of problems such as tumors or aneurysms more precise.

Important research in anxiety disorders is focusing on changes in the amygdala, which is sometimes referred to as the "fear center." This part of the brain regulates fear, memory, and emotion and coordinates these resources with heart rate, blood pressure, and other physical responses to stressful events. Some evidence suggests that the amygdala in people with anxiety disorders is highly sensitive to novel or unfamiliar situations and reacts with a high stress response.

Obsessive-compulsive disorder (OCD) is the anxiety disorder most strongly associated with specific brain dysfunction. For example, abnormalities in a specific pathway of nerves have been linked to OCD, attention deficit disorder, and Tourette syndrome. The symptoms of the three disorders are similar and they often coexist.

A number of imaging studies have reported less volume in the hippocampus in people with post-traumatic stress disorder. This important region is related to emotion and memory storage.

The influence of the family on anxiety is complicated by both genetic and psychological factors.

Panic Disorder and Family Influence. Certain psychodynamic theories suggest, and a few studies support the idea, that some people may develop panic disorder if they cannot resolve the early childhood conflict of dependence vs. independence. In one study, for example, young adults who had experienced childhood anxiety were more likely to live with their parents until their early to mid-twenties. Many people with panic disorder perceive their parents as being extremely controlling and overly protective while showing little actual affection.

Phobias and Family Influence. Several studies show a strong correlation between a parent's fears and those of the offspring. Although an inherited trait may be present, some researchers believe that many children can "learn" fears and phobias, just by observing a parent or loved one's phobic or fearful reaction to an event. People who have social phobias and severe agoraphobia generally report less parental affection and more strictness, overprotection, and encouragement of dependence than those without these disorders.

Obsessive-Compulsive Disorder and Family Influence. One study found that parental influence played no part in obsessive-compulsive disorder if the OCD patient was also not suffering from depression. However, depression coexists in two-thirds of OCD patients, and in the study patients who had both OCD and depression reported lower levels of parental care and overprotectiveness.

Traumatic events generally trigger anxiety disorders in individuals who are susceptible to them because of psychological, genetic, or biochemical factors. The clearest example is post-traumatic stress disorder. Specific traumatic events in childhood, particularly those that threaten family integrity, such as spousal or child abuse, can also lead to other anxiety and emotional disorders. Some individuals may even have a biological propensity for specific phobias, for instance of spiders or snakes, that have been triggered and perpetuated after a single exposure.

The acronym PANDAS (Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcus) is a term for an autoimmune condition associated with group A streptococcal infection in children (the cause of "strep throat" and rheumatic fever). Children with PANDAS develop tic-related disorders, including OCD and Tourette syndrome. In such cases, the OCD symptoms develop abruptly soon after the infection. It is unlikely to be an important cause of OCD.

Risk Factors

As many as 25% of all American adults experience intense anxiety sometime in their lives. The prevalence of true anxiety disorders is much lower, although they are still the most common psychiatric conditions in the United States and affect more than 20 million Americans.

Gender. With the exception of obsessive-compulsive disorder (OCD), women have twice the risk for most anxiety disorders as men. A number of factors may increase the reported risk in women, including cultural pressures to meet everyone else's needs except their own, and fewer self-restrictions on reporting anxiety to doctors.

Age. In general, phobias, OCD and separation anxiety show up early in childhood, while social phobia and panic disorder are often diagnosed during the teen years. Studies suggest that 3 - 5% of children and adolescents have some anxiety disorder. Children and adolescents who have an anxiety disorder are at risk of later developing other anxiety disorders, depression, and substance abuse.

Personality Factors. Children's personalities may indicate higher or lower risk for future anxiety disorders. For example, research suggests that extremely shy children and those likely to be the target of bullies are at higher risk for developing anxiety disorders later in life. Children who cannot tolerate uncertainty tend to be worriers, a major predictor of generalized anxiety. In fact, such traits may be biologically based and due to a hypersensitive amygdala -- the "fear center" in the brain.

Family History and Dynamics. Anxiety disorders tend to run in families. Genetic factors may play a role in some cases, but family dynamics and psychological influences are also often at work.

Social Factors. Several studies have reported a significant increase in anxiety levels in children and college students in the past two decades compared to children in the 1950s. In several studies, anxiety was associated with a lack of social connections and a sense of a more threatening environment. It also appears that more socially alienated populations have higher levels of anxiety. For example, a study of Mexican adults living in California reported that native-born Mexican Americans were three times more likely to have anxiety disorders (and even more likely to be depressed) as those who had recently immigrated to the U.S. The longer the immigrants lived in the U.S., the greater their risk for psychiatric problems. Traditional Mexican cultural and social ties seemed to protect recently arrived immigrants from mental illness.

Genetic Factors. Up to 50% of people with panic disorder and 40% of patients with generalized anxiety (GAD) have close relatives with the disorder. (About half of GAD patients also have family members with panic disorder, and about 30% have relatives with simple phobias.)

Obsessive-compulsive disorder (OCD) is also strongly related to a family history of the disorder. Close relatives of people with OCD are up to 9 times more likely to develop OCD themselves. Researchers are making progress in identifying specific genetic factors that might contribute to an inherited risk. Of particular interest are genes that regulate specific neurotransmitters (brain chemical messengers), including serotonin and glutamate. Recent research has suggested that the SLC1A1 gene, which is associated with glutamate regulation, may play an important role in early-onset OCD in boys. Research is also beginning to pinpoint regions on specific chromosomes (1, 3, 7, 6, 9, 15) that may contain genes linked to OCD.

However, there are no genetic tests to date that can identify patients at risk for anxiety disorders.

Medical Conditions. Although no causal relationships have been established, certain medical conditions have been associated with panic disorder. They include migraines, obstructive sleep apnea, mitral valve prolapse, irritable bowel syndrome, chronic fatigue syndrome, and premenstrual syndrome.

GAD affects about 1 - 5% of Americans in the course of their lives and is more common in women than in men. Some experts believe that it is underdiagnosed and more common than any other anxiety disorder. It is certainly the most common anxiety disorder among the elderly. GAD usually begins in childhood and often becomes a chronic ailment, particularly when left untreated. Depression in adolescence may be a strong predictor of GAD in adulthood. Depression commonly accompanies this anxiety disorder in any case.

Age and Panic Disorder. Studies indicate that the prevalence of panic disorder among adults is between 1.6 - 2% and is much higher in adolescence, 3.5 - 9%. Panic disorder usually first occurs either in late adolescence or in the mid-30s.

Gender and Panic Disorder. Women have about twice the risk for panic disorder as men. Panic attacks are very common after menopause. In one study, nearly 18% of older women reported panic attacks within a 6-month period, with over half of these attacks being full-blown. They tended to be associated with stressful life events and poor health. The effects of pregnancy on panic disorder appear to be mixed. It seems to improve the condition in some women and worsen it in others.

Obsessive-compulsive disorder occurs equally in men and women, and it affects about 2 - 3% of people over a lifespan. Most cases of OCD first develop in childhood or adolescence, although the disorder can occur throughout the life span.

Social anxiety disorder is currently estimated to be the third most common psychiatric disorder in the U.S. Studies have reported a prevalence of 7 - 12% in Western nations.

Age and Phobias. The onset of social anxiety disorder is usually during the early teenage years.

Gender and Phobias. Women are more likely to develop social anxiety disorder than men, although equal numbers of men and women seek treatment for it. Most people seeking treatment have had symptoms for at least 10 years.

Studies estimate a lifetime risk for PTSD in the U.S. of up to 8%. People exposed to traumatic events, of course, are at highest risk, but many people can go through such events and not experience PTSD. Studies estimate that 6 - 30% or more of trauma survivors develop PTSD, with children and young people being among those at the high end of the range. Women have the twice the risk of PTSD as men.

Furthermore, PTSD can occur in people not directly involved with a traumatic event. For example, 17% of the U.S. population outside New York City reported some symptoms of post-traumatic stress 2 months after the September 11 attack on the World Trade Towers. (In the city itself, where the attack occurred, an estimated 7.5% of New York's population reported PTSD within the month of the event, which declined to 0.6% at 6 months.)

Researchers are trying to determine factors that might increase vulnerability to catastrophic events and put people at risk for develop PTSD. Some studies report the following may be risk factors:

Pre-existing emotional disorder. People who have a history of an emotional disorder, particularly depression, before the traumatic event are at higher risk for PTSD.
Drug or alcohol abuse
A family history of anxiety
A history of abuse, particularly that which threatens family integrity, such as spousal or child abuse. Studies of individuals who had suffered physical or sexual abuse or neglect as children suggest that up to one-third develop PTSD.
An early separation from parents
Lack of social support and poverty
Sleep disorders. Insomnia and excessive daytime sleepiness even within a month after a traumatic event are important predictors for the development of PTSD. One specific sleep disorder -- sleep apnea -- may even intensify symptoms of PTSD, including sleeplessness and nightmares. Sleep apnea occurs when tissues in the upper throat (or airway) collapse at intervals during sleep, thereby blocking the passage of air. In one study, 91% of crime victims with PTSD had either sleep apnea or a lesser condition that partially blocked the airways during sleep. In fact, in one study treatment of sleep apnea eased PTSD. Sleep apnea has also been associated with a risk for panic disorder. [For more information, see In-Depth Report #65: Sleep apnea.]

Complications

Studies consistently report that all types of anxiety disorders can be very debilitating and seriously affect a person’s quality of life.

Depression. Depression is very common in people with an anxiety disorder, and it is sometimes difficult to distinguish one from the other because either or both can be accompanied by anxious feelings, agitation, insomnia, and problems with concentration.

Depression and nearly every anxiety disorder often go hand in hand, in both the young and old. In fact, the lifetime risk for depression in people with anxiety disorders may be higher than 70%. Furthermore, the combination of depression and anxiety is a major risk factor for both substance abuse and suicide. The following are examples of depression in specific anxiety disorders:

Between 50 - 65% of people with panic disorder also have major depression. Some studies have suggested that treating panic disorder early enough may help prevent major depression later on.
More than two-thirds of OCD patients suffer from depression.
Most patients with GAD will experience at least one episode of significant depression and many develop recurrent episodes. In patients with both disorders, GAD usually precedes the onset of depression.
Social anxiety during adolescence or young adulthood has been associated with a higher risk for depression, and the presence of both increases the chances for severe depression.
People with PTSD are four to seven times as likely to be depressed as are people without PTSD.

Bipolar Disorder. Symptoms of panic disorder are very common in people with bipolar disorder (manic-depression). In fact, people with bipolar have 26 times the rate of panic disorder as in the general population. Furthermore, anxiety worsens bipolar disorder. According to one study, anxiety disorders in teenagers were associated with bipolar disorder in adulthood, while manic behavior in adolescence was linked to later anxiety disorders.

Evidence now strongly supports an association between panic disorder and a risk for suicidal thoughts. Studies report that up to 18% of people with panic disorder attempt suicide and up to 38.5% regularly harbor suicidal thoughts, with the risks being higher in people with both panic disorder and depression. One study reported suicide attempts in about 12% of people with social phobias or OCD. If a person has an anxiety disorder and a mood disorders (such as depression), the risk for suicide is even higher.

Suicide is the third most common cause of death among adolescents, and is one of the most devastating events than can happen to a family. Suicide is most commonly associated with depression in young people, but it is also commonly associated with anxiety, psychosis, substance abuse, or impulsivity. More girls attempt suicide but more boys succeed, most often because they choose guns or violent methods while girls tend to overdose, which is more treatable. Nevertheless, unsuccessful attempts are major risk factors for a later suicide. Any expression of suicidal intent should be treated very seriously.

The following are danger signs in young people:

Withdrawal from friends
Sudden decrease in school performance
Loss of interest in activities that were previously pleasurable
Unusual irritability
Unusual changes in sleep or eating habits

Risk factors for suicide include a history of neglect or abuse, history of deliberate self-harm, a family member who committed suicide (nearly always one who shared a common mood disorder), access to firearms, and living in communities where there have been recent outbreaks of suicide in young people. A romantic break-up is often the trigger for a suicidal attempt in teenagers. Feeling connected with parents and family protected young people with depression in one study, regardless of gender or ethnicity.

In one study, adolescents failed to seek help for suicidal thoughts for the following reasons:

They believed nothing would help.
They were reluctant to tell anyone they had problems.
They thought it was a sign of weakness to seek help.
They did not know where to go.

Parents should not hesitate to seek professional help for their children if they suspect they are thinking about killing themselves. This is a medical emergency and requires immediate treatment.

[For more information on suicide, see In-Depth Report #8: Depression.]

Severely depressed or anxious people are at high risk for alcoholism, smoking, and other forms of addiction. Anxiety disorders are highly prevalent among people with alcoholism. Moreover, long-term alcohol use can itself cause biologic changes that may actually produce anxiety and depression.

Risk for Substance Abuse in Specific Anxiety Disorders. The following are some observations on specific anxiety disorders and substance abuse:

Some people with GAD and panic disorders may use alcohol or drugs to self-medicate.
Social phobia appears to pose a particular risk for alcohol abuse. People with this disorder are likely to drink in order to boost confidence. Alcohol itself has no direct beneficial effect on anxiety, but studies suggest that the belief in its effect appears to relieve anxious feelings. (Alcohol or substance abuse is not associated with specific phobias -- such as a fear of flying or spiders.)
Heavy smoking and substance abuse are common in people with PTSD. In adolescents, the disorder not only increases the risk for drug and alcohol use but also for eating disorders.

Studies consistently report that anxiety disorders have negative effects on work and relationships. Some examples:

In one study, more than 10% of patients with GAD missed at least 6 days of work within the previous month.
In a survey of OCD sufferers, 40% reported that they had to stop working because of the disorder. Only 40% worked full-time, while only half were married.
A 2006 study indicated that children with OCD are more likely to be bullied than other children.
Studies report that people with social phobias are less likely to get married, to leave home, and to finish school than those without this disorder. Their outlook worsens if they have other emotional disorders.

Anxiety disorders are associated with many different physical illnesses. Research suggests that people who have both an anxiety disorder and a physical illness have a worse quality of life and greater risk for disability than those who have only a physical illness. Anxiety disorders often tend to occur before the development of physical disorders.

Heart Disease. Anxiety has been associated with several heart problems, including unhealthy cholesterol levels, thicker blood vessels, and high blood pressure. Both anxiety and depression have been associated with a poorer response to treatment in heart patients, including a worse outcome after heart surgery.

Cholesterol is a soft, waxy substance that is present in all parts of the body including the nervous system, skin, muscle, liver, intestines, and heart. It is made by the body and obtained from animal products in the diet. Cholesterol is manufactured in the liver and is needed for normal body functions including the production of hormones, bile acid, and vitamin D. Excessive cholesterol in the blood contributes to atherosclerosis and subsequent heart disease. The risk of developing heart disease or atherosclerosis increases as the level of blood cholesterol increases.

Some researchers speculate that intense anxiety might trigger abnormal and dangerous heart rhythms in people with existing heart problems. In other studies, panic disorders, post-traumatic stress disorder, and phobias have been associated with a higher rate of sudden death from cardiac events, including heart attack.

Gastrointestinal Disorders. Anxiety frequently accompanies gastrointestinal conditions. Of note, half the cases of irritable bowel syndrome are associated with anxiety.

Headache. Both tension and migraine headaches are associated with anxiety disorders. One study reported that 32% of people with chronic tension headaches met criteria for anxiety. Similarly, another study reported that young girls with anxiety disorders were three times more likely to have chronic headaches than those without the disorder. (Headaches in both studies were also strongly associated with depression.)

Respiratory Problems. Studies report an association between anxiety in patients with obstructive lung conditions (asthma, emphysema, and chronic bronchitis) and more frequent relapses.

Obesity. Anxiety disorders may lead to obesity, and the reverse may also be true. A 2006 study suggested that anxiety disorders and depression in childhood may lead to higher body mass index (BMI) in adult women (but not men). Another 2006 study indicated that obesity is associated with a 25% increased risk of developing anxiety and mood disorders.

Allergic Conditions. Anxiety disorders are associated with numerous allergic conditions including hay fever, eczema, hives, food allergies, and conjunctivitis.

Other Conditions. Other physical conditions associated with anxiety disorders include thyroid problems and arthritis.

People with obsessive-compulsive disorders can experience skin problems from excessive washing, injuries from repetitive physical acts, and hair loss from repeated hair pulling (behavior known as trichotillomania).

Effect of PTSD on the Brain. Studies are reporting that PTSD is associated with shrinkage in the hippocampus, the part of the brain important for memory and learning. Some animal studies indicate that such damage may result from long-term exposure to cortisol, the major stress hormone. In one study, people who had suffered severe trauma scored 40% lower in tests of verbal memory than did the general population. There was no difference in IQ or in scores of other types of memory. Some studies suggest that exposure to chronic stress, common in PTSD patients, may even compromise the function of the brain’s receptors for anti-anxiety medication. On the other hand, a small hippocampal volume may itself increase stress hormone levels, so people with genetically smaller hippocampi may be susceptible to PTSD.

Effects of PTSD on Health. Studies of military veterans who have endured major traumatic events have found a higher risk for health problems. One study of Vietnam veterans reported that PTSD was associated with greater physical limitations, poorer physical health, and a lower quality of life than was found in the general population, regardless of other accompanying emotional or medical disorders. In another study of these veterans, PTSD sufferers had twice the risk for abnormal heart rhythms and four times the risk of a heart attack compared to men without PTSD.

Evidence suggests an association between anxiety in children and recurrent stomach aches. Anxiety has been associated with a higher risk for sleep disorders in children, such as frequent nightmares, restless legs syndrome, and bruxism (grinding and gnashing of the teeth during sleep).

Diagnosis

A physical examination and medical and personal history is essential. Because anxiety accompanies so many medical conditions, some serious, it is extremely important for the doctor to uncover any medical problems or medications that might underlie or be masked by an anxiety attack.

The patient should describe any occurrence of anxiety disorders or depression in the family and mention any other contributing factors, such as excessive caffeine use, recent life changes, or stressful events.

It is very important to be honest with your doctor about all conditions, including excessive drinking, substance abuse, or other psychological or mood states that might contribute to, or result from, the anxiety disorder.

Diagnosing children with an anxiety disorder can be very difficult, since anxiety often results in disruptive behaviors that overlap with attention-deficit hyperactivity or oppositional disorder. Other conditions with symptoms similar to anxiety disorders include pervasive developmental disorders such Asperger syndrome, learning disabilities, bipolar disorder, and depression. Many children have anxiety disorder and a co-occurring condition, which should be treated along with anxiety.

People with anxiety disorders are more likely to see a family doctor before a mental health specialist, since their symptoms are often physical. Symptoms can include muscle tension, trembling, twitching, aching, soreness, cold and clammy hands, dry mouth, sweating, nausea or diarrhea, or urinary frequency. Anxiety attacks can mimic or accompany nearly every acute disorder of the heart or lungs, including heart attacks and angina (chest pain). In fact, nearly all individuals with panic disorders are convinced that their symptoms are physical and possibly life-threatening.

Heart Problems. Studies suggest that up to a third of patients entering the emergency room with chest pain and who are low-to-moderate risk for a heart attack are actually suffering from panic attacks. It is often difficult even for specialists to distinguish between heart conditions and a panic attack:

Women who are having an actual heart attack or acute heart problem are much more likely to be misdiagnosed as having an anxiety attack than are men with similar symptoms.
Mitral valve prolapse, a common and usually mild heart problem, may have symptoms that are nearly identical to those of panic disorder. The two conditions, in fact, frequently occur together.

Mitral valve prolapse is a disorder in which the mitral valve does not close properly when the heart contracts. When the valve does not close properly it allows blood to backflow into the left atrium. Some symptoms can include palpitations, chest pain, difficulty breathing after exertion, fatigue, cough, and shortness of breath while lying down.

People with a heart-rhythm disturbance called paroxysmal supraventricular tachycardia have many of the same symptoms as those with panic attacks.

Asthma. Asthma attacks and panic attacks have similar symptoms and can also coexist.

Hyperthyroidism. Hyperthyroidism can cause many of the same symptoms of generalized anxiety disorder and must be ruled out.

Click the icon to see an image of hyperthyroidism.

Epilepsy. The symptoms of partial seizures and panic attacks often overlap.

Other Medical Conditions. In addition, anxiety-like symptoms are seen in many other medical problems, including hypoglycemia, recurrent pulmonary emboli, and adrenal-gland tumors. Women can also experience intense anxiety attacks with hot flashes during menopause.

Medication Side Effects. Many drugs, including some for high blood pressure, diabetes, and thyroid disorders, can produce symptoms of anxiety. Withdrawal from certain drugs, often those used to treat sleep disorders or anxiety, can also precipitate anxiety reactions.

Substance Abuse. People with anxiety disorders often drink alcohol or abuse drugs in order to conceal or eliminate symptoms, but substance abuse and dependency can also cause anxiety. In addition, withdrawal from alcohol can produce physiologic symptoms similar to panic attacks. Clinicians often have difficulty determining whether alcoholism or anxiety is the primary disorder. Overuse of caffeine or abuse of amphetamines can cause symptoms resembling a panic attack.

Clinicians use various screening tests to determine the causes, type, severity, and frequency of anxiety. Such tests include the Hamilton Anxiety Rating Scale, the Beck Anxiety Inventory, the Penn State Worry Questionnaire, and the Yale-Brown Obsessive Compulsive Scale.

Treatment

Anxiety disorders require treatment. Simply trying to talk oneself out of anxiety is as futile as trying to talk oneself out of a heart or stomach problem. Most anxiety disorders, especially phobias, respond well to treatment. They may, however, require long-term treatment. Many patients have a recurrence and may require additional medications. Nevertheless, most patients do not receive appropriate care for anxiety disorders. Many patients do not receive any treatment at all.

The standard current approach to most anxiety disorders is a combination of cognitive-behavioral therapy (CBT) and an antidepressant medication. A selective serotonin reuptake inhibitor (SSRI) is typically the first choice, with the serotonin-norepinephrine reuptake inhibitor (SNRI) venlafaxine (Effexor) an alternative. If patients do not respond to these drugs, tricyclic antidepressants or monoamine oxidase inhibitors (MAOIs) may be helpful. Benzodiazepines may be recommended for patients who are not helped by antidepressants. A healthy lifestyle that includes exercise, adequate rest, and good nutrition can also help to reduce the impact of anxiety.


Anxiety Disorder	Medications	Cognitive-Behavioral Therapy (CBT) and other Non-Drug Therapies
Generalized Anxiety Disorder	Antidepressants, benzodiazepines, and buspirone are helpful but have varying side effects. Investigational drugs include pregabalin and other anticonvulsants.	Cognitive-behavioral therapy or anxiety management therapy. Anxiety management therapy involves education, relaxation training, and exposure to anxiety-provoking stimuli but does not include cognitive restructuring.
Panic Attacks	SSRIs are treatment of choice. If patients do not respond to SSRIs, short-term treatment with a benzodiazepine may be used, or patients may switch to another type of antidepressant such as venlafaxine or tricyclics.	Cognitive-behavioral therapy, provided in 12 - 16 sessions over 3 - 4 months, focuses on recreating fear symptoms and helping patients change their response to them.
Social Anxiety Disorder	SSRIs or venlafaxine are first-line drug treatments. Benzodiazepines may help patients who do not respond to these antidepressants. In severe cases, an MAOI antidepressant may be prescribed. Anticonvulsants such as gabapentin (Neurontin) and pregabalin (Lyrica) are being investigated.	Cognitive-behavioral therapy can help improve symptoms after 6 - 12 weeks.
Obsessive-Compulsive Disorder	SSRIs are the first choice for adults. Clomipramine (a tricyclic antidepressant) is an alternative for adult patients who do not respond to SSRIs. For children, SSRIs do not seem to work as well for OCD as for other types of anxiety disorders.	Cognitive-behavioral therapy is the first treatment choice for children. For adults, either CBT or drug therapy may be offered as initial treatment. CBT techniques focus on exposure and response prevention (ERP).
Post-Traumatic Stress Disorder	Antidepressants, particularly SSRIs (sertraline and paroxetine approved for PTSD). The atypical antipsychotic olanzapine may be added to an antidepressant for patients who do not respond to a SSRI alone.	Trauma-focused psychological treatments include exposure therapy, trauma-focused cognitive therapy, and eye movement desensitization and reprocessing.
Note: For anxiety disorders in adults, the most effective treatments are usually combinations of drugs and CBT techniques. For children, CBT is usually the first treatment.

Medications

Selective serotonin-reuptake inhibitors (SSRIs), or the serotonin-norepinephrine reuptake inhibitor (SNRI) venlafaxine (Effexor), are the primary first-line treatment for anxiety disorders. For patients who are not helped by these drugs, benzodiazepines, either alone or in combination with an antidepressant, may be prescribed. Other types of antidepressants, including tricyclic antidepressants and monoamine oxidase inhibitors (MAOIs), may also be used to treat patients with severe or chronic forms of anxiety disorders.

Drug therapies for anxiety disorders work best in combination with cognitive behavioral therapy.

Selective Serotonin Reuptake Inhibitors (SSRIs). SSRIs include fluoxetine (Prozac), sertraline (Zoloft), paroxetine (Paxil), fluvoxamine (Luvox), citalopram (Celexa), and escitalopram (Lexapro).

SSRIs can cause agitation, nausea, and diarrhea. Sexual function side effects include low sex drive, inability to have an orgasm, and impotence. Over time, many SSRI-treated patients gain weight, although the degree of weight gain varies depending on the drug. Elderly people taking these drugs should take the lowest effective dose possible, and those with heart problems should be monitored closely.

There have been many concerns about SSRIs and increased risk for suicidal behavior. Both adults and children who are treated with SSRIs should be carefully monitored for any worsening of depressive symptoms or changes in behavior. This is especially important during the first few months of antidepressant treatment.

Paroxetine has been linked to heart-related birth defects when women took this drug during the first trimester of pregnancy. Experts are also advising caution in prescribing other types of SSRIs to pregnant women. While certain SSRIs may carry increased risks for some specific type of rare birth defects, research suggests that the overall risks are minimal. Still, women who are pregnant or who are considering becoming pregnant should discuss the potential risks of these drugs with their doctors.

Serotonin-norepinephrine reuptake inhibitors (SNRIs). SNRIs are known as dual inhibitors because they work on two neurotransmitters -- norepinephrine and serotonin. Venlafaxine (Effexor) is an SNRI that is approved for treatment of generalized anxiety disorder, social anxiety disorder, and panic disorder in adults. (It is not approved for children.) As with many SSRIs, venlafaxine impairs sexual function. Venlafaxine can increase blood pressure and heart rate and should be used with caution in patients with high blood pressure or heart disease. Some patients report severe withdrawal symptoms, including dizziness and nausea. This drug has a serious risk for overdose. Venlafaxine should not be taken during the last trimester of pregnancy because the drug can cause complications in newborn infants.

Duloxetine (Cymbalta) also acts on both serotonin and norepinephrine. In 2007, it was approved for treatment of generalized anxiety disorder. Side effects are generally mild and include dry mouth, nausea, and sleepiness. Patients with narrow-angle glaucoma or patients with liver or kidney diseases should not take duloxetine. Because duloxetine can cause liver damage, patients who drink large quantities of alcoholic beverages should not take it.

Mitrazapine (Remeron) is another type of SNRI that is sometimes used for treatment of post-traumatic stress disorder and social anxiety disorder.

Tricyclic Antidepressants. Tricyclics are an older type of antidepressant. Tricyclics used for treatment of anxiety disorder include imipramine (Tofranil, for generalized anxiety disorder, panic disorder), nortriptyline (Pamelor, for panic disorder), desipramine (Norpramin, for panic disorder), and clomipramine (Anafranil, for obsessive compulsive disorder). Clomipramine is approved specifically for OCD, but because of its severe side effects it is usually used only if SSRIs have failed to help.

Side effects of TCAs include sleep disturbance, abrupt reduction in blood pressure upon standing, weight gain, sexual dysfunction, and mental disturbance. Elderly patients and those with a history of seizures, cardiac problems, closed-angle glaucoma, and urinary retention or obstruction should be closely supervised when taking tricyclics.

Monoamine Oxidase Inhibitors. Monoamine oxidase inhibitors (MAOIs) are the oldest type of antidepressant. The MAOI phenelzine (Nardil) is sometimes used to treat social anxiety disorder or post-traumatic stress disorder that has not responded to other treatments.

MAOIs commonly cause weight gain, drowsiness, dizziness, sexual dysfunction, and insomnia. Dietary restrictions are the main problem with these drugs. Severe high blood pressure (hypertension) can be brought on by eating certain foods that have a high tyramine content, including cheese, red wine, and processed meats. High blood pressure can also occur when MAOIs are taken with certain drugs, including some common over-the-counter cough medications and decongestants. MAOIs can cause birth defects and should not be taken by pregnant women.

Most serious, fatal reactions can occur when MAOIs and SSRIs or venlafaxine are taken at the same time. There should be at least a 2- to 5-week break if a patient is changing from one type of antidepressant to the other.

Benzodiazepines are safe and effective medications for most anxiety disorders and have been the standard of treatment for years. However, their on-going use has been associated with a high risk for dependency and abuse. Therefore, they have been supplanted in most cases by SSRIs and other newer antidepressants. For anxiety disorders, benzodiazepines are most often used to treat panic disorder, and are sometimes used for social anxiety disorder and generalized anxiety disorder. These drugs include alprazolam (Xanax), clonazepam (Klonopin), and lorazepam (Ativan).

Benzodiazepines have many side effects, generally associated with chronic use. The most common are daytime drowsiness and a hung-over feeling. In rare cases, they can cause agitation. They may worsen respiratory problems. Benzodiazepines are potentially dangerous when used in combination with alcohol. Overdoses can be serious, although they are very rarely fatal.

The elderly are more susceptible to side effects and should usually start at half the dose prescribed for younger people. These drugs increase the risk of falling, which can increase the risk for hip fracture in older people. Also of concern are studies showing a high risk of automobile accidents in people who take benzodiazepines. Benzodiazepines taken during pregnancy are associated with birth defects, and they should not be used by pregnant women or by nursing mothers.

Loss of Effectiveness and Dependence. Eventually these drugs can lose their effectiveness with continued use at the same dosage. As a result, patients may want to increase their dosage to prevent anxiety. This causes dependency, which can occur after taking these drugs for several weeks.

Withdrawal and its Treatments. Withdrawal symptoms can be very severe, even in people who rapidly discontinue benzodiazepines after taking them for only 4 weeks. Symptoms include sleep disturbance and anxiety, which can develop within hours or days after stopping the medication. Some patients experience stomach distress, sweating, and insomnia, which can last 1 - 3 weeks. The longer the drugs are taken and the higher their dose, the more severe these symptoms can become. Simply tapering off gradually helps about 60% of people stop taking these drugs. Certain medications (anti-seizure drugs, antidepressants, buspirone) may also help with withdrawal.

Azapirones, such as buspirone (BuSpar), act on serotonin receptors called 5-HT(1A). Buspirone appears to work as well as a benzodiazepine for treating generalized anxiety disorder. It usually takes several days to weeks for the drug to be fully effective. It is not useful against panic attacks.

Buspirone does not produce any immediate euphoria or change in sensation, so some people believe, erroneously, that the drug doesn't work. Such qualities result in a very low potential for abuse. In fact, unlike the benzodiazepines, buspirone is not addictive, even with long-term use, so it may be particularly useful for the patient whose anxiety disorder coexists with alcoholism or drug abuse.

Buspirone also seems to have less pronounced side effects than benzodiazepines and no withdrawal effects, even when the drug is discontinued quickly. Common side effects include dizziness, drowsiness, and nausea. Buspirone should not be used with monoamine oxidase inhibitors (MAOIs).

Beta-blockers, including propranolol (Inderal) and atenolol (Tenormin), block the nerves that stimulate the heart to beat faster. They affect only the physiologic symptoms of anxiety (particularly rapid heart rate) and are most helpful for phobias, particularly performance anxiety. They may be taken before entering a situation where anxiety symptoms tend to occur. Beta-blockers are less effective for other forms of anxiety.

Atypical antipsychotics are mostly used for treating schizophrenia, bipolar disorder, and major depressive disorder. Doctors sometimes use the atypical antipsychotic olanzapine (Zyprexa) for treating severe cases of post-traumatic stress disorder. However, olanzapine has severe side effects, including weight gain and increased high blood sugar levels, which can increase the risk for diabetes. [For more information, see In-Depth Report #47: Schizophrenia.]

Pregabalin (Lyrica) and gabapentin (Neurontin) are drugs used to treat seizures and other conditions. Researchers are investigating whether these drugs may be useful for certain anxiety disorders, such as social anxiety disorder and general anxiety disorder. Their exact role in the treatment of anxiety disorders is not clear, however.

Generally, manufacturers of herbal remedies and dietary supplements do not need FDA approval to sell their products. Just like a drug, herbs and supplements can affect the body's chemistry, and therefore have the potential to produce side effects that may be harmful. There have been a number of reported cases of serious and even lethal side effects from herbal products. Always check with your doctor before using any herbal remedies or dietary supplements.

Studies indicate that the dietary supplement inositol may have benefits for panic disorder and, possibly, obsessive compulsive disorder. Inositol is part of the vitamin B complex.

Some patients use aromatherapy as a relaxation aid. Aromatherapy is in general safe, but some plant extracts in these formulas have been linked to skin allergies.

There is no evidence supporting the efficacy of valerian, St. John’s wort, or passionflower for treatment of anxiety. The herbal remedy kava has been associated with liver problems and should not be avoided, especially by patients with liver disease or those who use alcohol. Kava can also interact dangerously with medications that are metabolized by the liver.

The goal of cognitive-behavioral therapy (CBT) is to regain control of reactions to stress and stimuli, thus reducing the feeling of helplessness that often accompanies anxiety disorders. CBT works on the principle that the thoughts that produce and maintain anxiety can be recognized and altered using various techniques that change behavioral responses and eliminate the anxiety reaction. Many studies have shown that a combination of CBT and medication works best for treating anxiety disorders.

A number of CBT approaches work well for treating many types of anxiety disorders. Studies suggest that CBT is also helpful for patients who have additional conditions, such as depression, a second anxiety disorder, or alcohol dependency. (It may take longer to achieve a successful outcome in such cases, however.) CBT is often given along with drug treatment. A study in the Journal of the American Medical Association found that children and adolescents with OCD responded better to CBT alone than the antidepressant setraline (Zoloft) alone, but most patients did best when they were treated with a combination of CBT and sertraline.

Both individual and group treatments work well. (However, people with social phobia may do better in individual sessions.) Several recent studies also indicate that telephone-based behavioral therapy works well for people with OCD, generalized anxiety disorder, and panic disorders.

Anxiety disorders are chronic, however, and recurrence is common. Some studies indicate that 30 - 82% of people with panic disorder and phobias have a recurrence of attacks at an average of 9 months, even after successful short-term therapy. Medications, then, are also generally recommended for most patients.

Basic Cognitive Therapy Techniques. Treatment usually takes about 12 - 20 weeks. The essential goal of cognitive therapy is to understand the realities of an anxiety-provoking situation and to respond to reality with new actions based on reasonable expectations.

First, the patient must learn how to recognize anxious reactions and thoughts as they occur. One way of accomplishing this is by keeping a daily diary that reports the occurrences of anxiety attacks and any thoughts and events associated with them. A patient with OCD, for instance, may record repetitive thoughts.
These entrenched and automatic reactions and thoughts must be challenged and understood. Again, using the OCD example, one approach is to record and play back the words of the repetitive thoughts, over exposing the patient to the thoughts and reducing their effect. One effective approach for patients with generalized anxiety disorder targets their intolerance of uncertainty and helps them develop methods to cope with it.
Patients are usually given behavioral homework assignments to help them change their behavior. For example, a person with generalized social phobia may be asked to buy an item and then return it the next day. As the patient performs this action, they observe any unrealistic fears and thoughts triggered by such an event.
As the patient continues with self-observation, they begin to perceive the false assumptions that underlie the anxiety. For example, OCD patients may learn to recognize that their heightened sense of responsibility for preventing harm in non-threatening situations is not necessary or even useful.
At that point, the patient can begin substituting new ways of coping with the feared objects and situations.

Systematic Desensitization. Systematic desensitization is a specific technique that breaks the link between the anxiety-provoking stimulus and the anxiety response. This treatment requires the patient to gradually confront the object of fear. There are three main elements to the process:

Relaxation training
A list composed by the patient that prioritizes anxiety-inducing situations by degree of fear
The desensitization procedure itself, confronting each item on the list, starting with the least stressful

This treatment is especially effective for simple phobias, social phobias, agoraphobia, and post-traumatic stress syndrome.

Exposure and Response Treatment. Exposure treatment purposefully generates anxiety by exposing the patient repeatedly to the feared object or situation, either literally or using imagination and visualization. It uses the most fearful stimulus first. (This differs from the desensitization process because it does not involve relaxation or a gradual approach to the source of anxiety.)

Exposure treatments are usually known as either flooding or graduated exposure:

Flooding exposes the person to the anxiety-producing stimulus for as long as 1 - 2 hours.
Graduated exposure gives the patient a greater degree of control over the length and frequency of exposures.

In both cases, the patient experiences the anxiety over and over until the stimulating event eventually loses its effect. Combining exposure with standard cognitive therapy may be particularly beneficial. This approach has helped certain patients in most anxiety disorder categories, including post-traumatic stress disorder.

Modeling Treatment. Phobias can often be treated successfully with modeling treatment:

The therapy typically uses an actor who approaches an anxiety-producing object or engages in a fear-provoking activity that is similar to the patient's specific problem. Either a live or videotaped situation may be used, although the live model is considered to be more effective.
The patient observes this event and tries to learn how to behave in a comparable manner.

Other forms of psychotherapy, commonly called emotion-based psychotherapy (EBT), psychodynamic therapy, or "talk" therapy, deal more with childhood roots of anxiety and usually, although not always, require longer treatments. They include interpersonal therapy, supportive psychotherapy, attention intervention, and psychoanalysis. All work is done during the sessions. Some research indicates that such therapies might be more useful for generalized anxiety, which may require more sustained work to process and recover from early traumas and fears. Studies suggest that although emotion-based psychotherapies are not as effective as cognitive-behavioral therapy (CBT) in treating panic disorders, patients tend to stay longer in EBT than in CBT. Some doctors suggest adding elements of EBT to the usual CBT and medication treatments.

Anxiety Management Therapy. Anxiety management therapy is sometimes used as an alternative to CBT for generalized anxiety disorder. It involves patient education, relaxation training, and exposure to anxiety-provoking stimuli but does not include exercises in cognitive retraining.

Relaxation Training. Relaxation techniques use muscle relaxation and mental visualization to help focus attention towards a calming feeling. Some people find meditation helpful.

Breathing Retraining. Breathing retraining techniques may help reduce the physical effects of anxiety. For example, hyperventilation is one of the primary physical manifestations of panic disorders. This involves rapid, tense breathing, resulting in chest pain, dizziness, tingling of the mouth and fingers, muscle cramps, and even fainting. By practicing measured, controlled breathing at the onset of a panic attack, patients may be able to prevent full attacks.

Biofeedback. Biofeedback uses special sensors that allow patients to recognize anxiety states by changes in specific physical functions, such as changes in pulse rate, skin temperatures, and muscle tone. Eventually they learn to modify these changes, which in turn helps relieve anxiety. While commonly used, there are not many rigorous studies showing that biofeedback helps patients reduce or eliminate their symptoms over the long term.

Several types of psychological treatments have been designed specifically for treating patients with PTSD. These approaches include a special type of CBT known as trauma-focused cognitive behavioral therapy (TFCBT), and a psychotherapy treatment called eye movement desensitization and reprocessing (EMDR).

With TFCBT, patients are taught stress management skills. The therapist helps the patient develop a narrative (verbal, written, or artistic) about the traumatic event. Patients may be exposed to reminders about the trauma and are taught how to cope with future reminders. Through the process, the patient learns how to reprocess their thoughts, feelings, and behaviors.

With EMDR, the patient focuses on remembering the traumatic experience while visually following the rhythmic movement of the therapist’s fingers. The patient recounts to the therapist what memories have been provoked during the exercise. EMDR may help patients recall details and sensations that they had blocked out. Through this breakthrough, patients learn how to regain emotional control.

Transcranial magnetic stimulation (TMS) uses high frequency magnetic pulses to target and stimulate specific areas of the brain. Research has particularly focused on possible benefits for obsessive-compulsive behavior. Some studies have found some improvement in mood, but more research is needed to determine its value for reducing anxiety and obsessions.

In 2006, the U.S. National Institutes of Health funded a large study to examine whether deep brain stimulation (DBS) can help patients with OCD. DBS involves implanting tiny stimulators into the brain to block abnormal nerve signals that cause obsessive symptoms. These “brain pacemakers” are approved to treat epilepsy and Parkinson’s disease. Researchers hope that DBS may eventually provide a new treatment option for patients with severe OCD.

A surgical technique called cingulotomy involves interrupting the cingulate gyrus, a bundle of nerve fibers in the front of the brain. It is sometimes used as a last resort for patients with severe OCD. A variation of this procedure using magnetic resonance imaging (MRI) to guide the surgeon has resulted in long-term improvement in about 25 - 33% of OCD patients in whom it is performed. The procedure is generally safe with few serious complications and does not affect intellect or memory.

Smoking and Skin Damage

The skin of smokers ages more rapidly than the skin of non-smokers, even in areas of the body not exposed to sunlight, according to a 2007 study. Women in the study who smoked also had much lower levels of vitamin E secretions in their skin. Vitamin E may protect the skin from sun damage.
There may be an association between smoking and higher frequency of a type of acne (noninflammatory acne) in adult women, according to a European study.

Antioxidants and Your Skin

A study in the Journal of Nutrition found that a combination of antioxidants and trace elements supplementation raises the risk of skin cancer in women, but not in men.

Ultraviolet Radiation

Overall, exposure to ultraviolet radiation from sunlight (radiation referred to as UVA or UVB) accounts for about 90% of the symptoms of premature skin aging.
UVB primarily affects the outer skin layers. It is most intense when sunlight is brightest. People receive slightly over 70% of their yearly UVB dose during the summer.
UVA penetrates more deeply and efficiently. The intensity of UVA rays is less dependent on the time of day and season of the year than that of UVB rays.

Vitamin D

A report analyzing studies of vitamin D supplementation found that people who take vitamin D supplements live longer than those who do not. People who avoid sunlight are at risk for vitamin D deficiency.

Introduction

As you age, your skin undergoes progressive changes:

The cells divide more slowly, and the inner layer of skin (the dermis) starts to thin. Fat cells beneath the dermis begin to shrink. In addition, the ability of the skin to repair itself decreases with age, so wounds heal more slowly. The thinning skin becomes vulnerable to injuries and damage.
The deeper layer of the skin, which provides scaffolding for the surface skin layers, loosens and unravels. Skin then loses its elasticity (ability to stretch). When pressed, it no longer springs back to its initial position. Instead, older skin sags and forms furrows.
The sweat- and oil-secreting glands atrophy (waste away), leaving the skin without a protective layer of water and fat. The skin's ability to stay moisturized then decreases, and it becomes dry and scaly.
Frown lines (those between the eyebrows) and crow's feet (lines that spread from the corners of the eyes) appear to develop because of permanent small muscle contractions. Habitual facial expressions also form characteristic lines.
Gravity makes the situation worse, contributing to the formation of jowls and drooping eyelids. Eyebrows, surprisingly, move up as a person ages, possibly pulled up by forehead wrinkles.

Wrinkles can have a profound impact on self-esteem. The stigma attached to looking old is evidenced by the more than $12 billion Americans spend each year on cosmetics to hide the signs of aging. Our society places a premium on youthfulness, and age discrimination in the workplace, although illegal, has stalled many people's careers. Indeed, the emotional consequences of aging explain in large part why the cosmetics industry and plastic surgeons thrive.

The sun is the most important cause of prematurely aging skin (a process called photoaging) and skin cancers. Overall, exposure to ultraviolet radiation from sunlight (radiation referred to as UVA or UVB) accounts for about 90% of the symptoms of premature skin aging. Most of these effects occur by age 20:

Even small amounts of UV radiation trigger the processes leading to skin wrinkles.
Long-term repetitive exposure to sunlight adds up, and likely is responsible for the vast majority of unwanted consequences of aging skin, including basal cell and squamous cell cancers.
Intense exposure to sunlight in early life is an important cause of melanoma, a particularly aggressive type of skin cancer.

Initial Damaging Effects of Sunlight. Ultraviolet radiation penetrates the layers of the skin. Both UVA and UVB rays cause damage leading to wrinkles, lower immunity against infection, aging skin disorders, and cancer. They appear to damage cells in different ways, however.

UVB is the main cause of sunburns, and primarily affects the outer skin layers. UVB is most intense at midday when sunlight is brightest. People receive slightly over 70% of their yearly UVB dose during the summer. We receive only 28% during the remainder of the year. Window glass filters out UVB.
UVA penetrates more deeply and efficiently. The intensity of UVA rays is less dependent on the time of day and season of the year than that of UVB rays. For example, you receive only about half of your yearly UVA dose during the summer months, with the balance spread over the rest of the year. Window glass does NOT filter out UVA.

Both UVA and UVB rays cause damage to the body, including genetic injury, wrinkles, aging skin disorders, and skin cancers. Exactly how they cause this damage is not yet fully understood.

Processes Leading to Wrinkles. Even small amounts of UV radiation trigger the processes that can cause wrinkles:

Sunlight damages collagen fibers (the major protein that gives structure to the skin). Sunlight also causes damage to elastin, a protein in the skin that normally maintains springiness and strength of tissue beneath the skin.
In response to this sun-induced elastin accumulation, the body produces large amounts of enzymes called metalloproteinases. One study indicated that when people with light to moderate skin color are exposed to sunlight for just 5 - 15 minutes, the metalloproteinase levels in their body remain high for about a week.
The normal function of these metalloproteinases is generally positive -- to remodel the sun-injured tissue by producing and repairing collagen. This is an imperfect process, however, and some of metalloproteinases produced by sunlight actually degrade (break down) collagen. The result is an uneven formation (matrix) of disorganized collagen fibers called solar scars. Repetition of this imperfect skin rebuilding causes wrinkles.
An important event in this process is the over-production of oxidants, also called free radicals. These are unstable molecules that are normally produced by chemical processes in the body, a process called oxidation. Environmental damage, however, causes an overproduction of oxidants. Excessive amounts of oxidants damage the body's cells and even alter their genetic material. Oxidation may contribute to wrinkling by activating the specific metalloproteinases that degrade connective tissue.

In addition to sunlight, other factors may hasten the formation of wrinkles:

Cigarette Smoke. Smoking produces oxygen-free radicals, which accelerate wrinkles and aging skin disorders, and increase the risk for non-melanoma skin cancers. Studies also suggest that smoking and subsequent oxidation produce higher levels of metalloproteinases, the enzymes associated with wrinkles.

Air Pollution. Ozone, a common air pollutant, may be a particular problem for the skin. One study reported that it might deplete the amount of vitamin E in the skin. This vitamin is an important antioxidant.

Rapid Weight Loss. If weight loss occurs too rapidly, the volume of fat cells that cushion the face are also decreased before chemicals in the skin can react. This not only makes a person look gaunt, but can cause the skin to sag.

Blemishes

This report covers three types of blemishes: Liver spots, purpura, and seborrheic keratoses (or warts).

Liver spots (known as lentigos, or sun-induced or pigmented lesions) are flat brown spots on the skin. They are almost universal signs of aging. Occurring most noticeably on the hands and face, these blemishes tend to enlarge and darken over time. The extent and severity of the spots are determined by a combination of skin type, sun exposure, and age. These spots are harmless, but should be distinguished from lentigo maligna, which is an early sign of melanoma.

Liver spots or age spots are a type of skin change that are associated with aging. The increased pigmentation may be brought on by exposure to sun, or other forms of ultraviolet light, or other unknown causes.

Treating Liver Spots. Liver spots do not require treatment, although some people are distressed by their appearance. Treatments may include the following:

Trichloroacetic acid (a chemical peel).
Tretinoin (Retin A) alone or in a combination with Mequinol (Solagé). Tretinoin is related to vitamin A, and is also effective in treating wrinkles.
Gentle freezing with liquid nitrogen (cryotherapy).
Laser treatment. Specific lasers, such as the Nd:YAG, are effective in eliminating 80% of liver spots in one treatment. It may be more effective than cryotherapy and have fewer side effects.
Bleaching creams -- these are commonly available but are not as satisfactory as peels, and high concentrations can sometimes cause permanent loss of skin color.

Purpura occurs when tiny capillaries (blood vessels) break and leak blood into the skin. In older people, the condition (called senile or actinic purpura) is usually caused by fragile blood vessels. The capillaries appear as flat purplish patches. These patches are called petechiae when they are smaller than 3 mm (about a tenth of an inch). When they are greater than 3 mm, they are referred to as ecchymoses. Patients typically complain of a rash, which may appear reddish at first but gradually change color, turning brown or purple.

Treatment. Although there is no specific treatment for purpura, patients are advised to avoid trauma, including vigorous rubbing of the skin, which may be sufficient to damage the capillaries. Emollients that soften the skin may be helpful. Some doctors also recommend vitamin C, but its effectiveness is unproven.

Seborrheic keratoses, (also called seborrheic warts), are among the most common skin disorders in older adults. Their cause or causes are unknown. They usually appear on the head, neck, or trunk and can range in size from 0.2 - 3 cm (a little over an inch). They are well defined and appear to be pasted onto the skin, but their appearance can vary widely:

They can be smooth with tiny, round, pearl-like formations embedded in them.
They can be rough and warty.
They can be brown or black.

Seborrheic keratoses sometimes look like melanoma, since they can have an irregular border, but they are always benign. A dermatologist can tell the difference between them, although experts warn that melanomas may "hide" among these benign lesions and go unnoticed without close inspection. In general, seborrheic keratoses have a uniform appearance while melanomas often have a smooth surface that varies in height, color density, and shading. In some cases, keratoses may cause itching or irritation. They can be easily removed with surgery or freezing. Vitamin D3 ointment is also showing promise in clinical trials.

Risk Factors

Exposure to Sun in Childhood. It is estimated that 50 - 80% of skin damage occurs in childhood and adolescence from intermittent, intense sun exposure that causes severe sunburns. In spite of this now well-known effect, many people still believe that a tan in children signifies health. And even though many parents are concerned about sun exposure, they still rely too much on sunscreen and not enough on protective clothing.

The Elderly. Most people over 70 have at least one skin disorder. Many have three or four. Everyone experiences skin changes as they age, but a long life is not the sole determinant of aging skin. Family history, genetics, and behavioral choices all have a profound impact on the onset of aging-skin symptoms.

Of all the risk factors for aging skin, exposure to UV radiation from sunlight is by far the most serious. Indeed, the vast majority of undesirable consequences of aging skin occur in individuals who are repetitively exposed to the sun, including the following:

Outdoor workers, such as farmers, fishermen, construction workers, and lifeguards
Outdoor enthusiasts
Sunbathers
People who regularly attend tanning salons or use tanning beds (One study indicated that regular use significantly increases the risk for non-melanoma skin cancers. Fair-skinned women under age 50 may be at particular risk.)

Experts have devised a classification system for skin phototypes (SPTs) based on the sensitivity to sunlight. It ranges from SPT I (lightest skin plus other factors) to IV (darkest skin). People with skin types I and II are at highest risk for photoaging skin diseases, including cancer. It should be noted, however, that premature aging from sunlight can affect people of all skin shades.


Skin Type	Tanning and Burning History
I	Always burns, never tans, sensitive to sun exposure
II	Burns easily, tans minimally
III	Burns moderately, tans gradually to light brown
IV	Burns minimally, always tans well to moderately brown
V	Rarely burns, tans profusely to dark
VI	Never burns, deeply pigmented, least sensitive

The common belief is that women are at greater risk for wrinkles than men. Some evidence suggests, however, that given the same risk factors, men and women in the same age groups have comparable risks for skin photoaging. In a French study, the evidence of moderate-to-severe photoaging was observed in the following:

Twenty two percent of women and 17% of men ages 45 - 49
Thirty six percent of women and 38% of men by age 54
Nearly half of both men and women by age 60

Some studies report that men are more likely to develop non-melanoma skin cancers.

Heavy smokers are almost five times more likely to have wrinkled facial skin than nonsmokers, according to one study. The skin of smokers in areas of their bodies not exposed to sunlight also seems to age more rapidly, compared to non-smokers in the same age group, according to a 2007 study. In fact, heavy smokers in their 40s often have facial wrinkles more like those of nonsmokers in their 60s.

Studies of identical twins have found smokers to have thinner skin (in some cases by as much as 40%), more severe wrinkles, and more gray hair than their non-smoking twins. Even worse, cigarette smokers are more prone to skin cancers, including squamous cell carcinoma and giant basal cell carcinomas. A European study found an association between smoking and higher frequency of a particular type of acne in adult women. The study also found that women who smoked had much lower levels of vitamin E secretions in their skin. Vitamin E is an antioxidant that may help protect the skin from sun damage. [See In-Depth Report #41: Smoking.]

Prevention

The best long-term prevention for overly wrinkled skin is a healthy lifestyle.

Eat Healthy. A diet with plenty of whole grains, fresh fruits and vegetables, and the use of healthy oils (such as olive oil) may protect against oxidative stress in the skin. One study reported that people over age 70 years had fewer wrinkles if they ate such foods. Diet played a role in improving skin regardless of whether the people in the study smoked or lived in sunny countries. Benefits from these foods may be due to high levels of anti-oxidants found in them.

Exercise. Daily exercise keeps blood flowing, which brings oxygen to the skin. Oxygen is an important ingredient for healthy skin.

Reduce Stress. Reducing stress and tension may have benefits on the skin.

Quit Smoking. Smoking not only increases wrinkles, but smokers have a risk for squamous cell cancers that is 50% higher than nonsmokers' risk. Smokers should quit smoking to prevent many health problems, not just unhealthy skin.

The following are some daily measures for skin protection:

Don't wash your face too often with tap water. (Once a day is enough.) It strips the skin of oil and moisture. In addition, chlorinated water, particularly at high temperatures, poses special risks for wrinkles.
Wash your face with a mild soap that contains moisturizers. Avoid alkaline soaps, especially with deodorant.
Pat the skin dry and immediately apply a water-based moisturizer.
Always apply sunscreen, even if going outdoors for short periods.
Avoid drinking alcohol within 3 hours of bedtime. Alcohol increases the risk for leaks in the capillaries, which allows more water in and causes sagging and puffiness. Capillary leakage increases when one is lying down.
Lie on the back when sleeping. This helps offset the effects of gravity.

One of the most important ways to prevent skin damage is to avoid episodes of excessive sun exposure. The following are some specific guidelines:

Use sunscreens that block out both UVA and UVB radiation. However, do not rely only on sunscreen for sun protection. Wear protective clothing and sunglasses in addition.
Avoid exposure particularly from 10 a.m. to 4 p.m., when sunlight pours down 80% of its daily UV dose.
Avoid reflective surfaces, such as water, sand, concrete, and white-painted areas. Clouds and haze are not protective and in some cases may intensify UVB rays.
Ultraviolet intensity depends on the angle of the sun, not heat or brightness. So the dangers are greater the closer to the summer-start date. For example, in the Northern Hemisphere, UV intensity in April (2 months before summer starts) is equal to that in August (2 months after summer begins).
The higher the altitude the quicker one sunburns. One study suggested, for example, that an average complexion burns in 6 minutes at an altitude of 11,000 feet at noon, compared with 25 minutes at sea level in a temperate climate.
Avoid sun lamps and tanning beds or salons. They provide mostly high-output UVA rays. Some experts believe that 15 - 30 minutes at a tanning salon is as dangerous as a day spent in the sun. People should not be misled by advertising claims of "safe" tanning or promotions offering unlimited tanning.

Sunscreens. The use of sunscreens is complex, and everyone should understand how and when to use them. The bottom line is not that people should avoid sunscreens or sunblocks, but that they should always use them in combination with other sun-protective measures.

Protective Clothing. Wearing sun-protective clothing is extremely important and protects even better than sunscreens. Special clothing is now available for blocking UV rays and is rated using SPF ratings or a system called the UPF (ultraviolet protection factor) index, with 50 UPF being the highest. (According to one study, this is a very reliable indicator of protection.) The clothing is expensive, however. The following are some tips for everyone:

Adults and children should wear hats with wide brims. Even wearing a hat, however, may not be fully protective against skin cancers on the head and neck.
People should look for loosely fitted, unbleached, tightly woven fabrics. The tighter the weave, the more protective the garment.
Washing clothes over and over improves UPF by drawing fabrics together during shrinkage. An easy way to assess protection is simply to hold the garment up to a window or lamp and see how much light comes through. The less the better.
Everyone over age 1 should wear sunglasses that block all UVA and UVB rays.

Chemical Tanners. Some research suggests that melanin and dihydroxyacetone (DHA), the active ingredients in many self-tanning lotions, may help filter out UVA and UVB radiation and are therefore protective against sun damage More research is underway. A preliminary study funded by the National Cancer Institute found that people who received numerous daily injections of melanotan-1 (MT-1) before going in the sun or a tanning bed tanned more quickly and showed fewer signs of sun-related damage. MT-1 is a synthetic version of the hormone melanin, which helps produce the skin's natural pigment (color).

In choosing a sunscreen, look at the ingredients. Preparations that help block UV radiation are sometimes classified as sunscreens or sunblocks, according to the substances they contain. In general, sunscreens contain organic formulas and sunblocks inorganic formulas. However, the term sunblock is used less and less as sunscreens increasingly contain both kinds of ingredients:

Organic formulas contain UV-filtering chemicals such as octocrylene, octyl salicylate, homosalate, and octyl methoxycinnamate (block UVB), avobenzone-Parsol 1789 (blocks UVA), cinoxate, ethylhexyl p-methoxycinnamate (blocks UVB and small amounts of UVA), oxybenzone, benzophenone-3 (blocks UVA/UVB). People should look for a wide-spectrum sunscreen that contains combinations of these ingredients and filter both UVA and UVB. Of note: para-amino benzoic acid (PABA), once a popular ingredient, is now used infrequently. PABA may actually break down in the presence of UV exposure and release harmful oxidants. In addition, many people have an allergic reaction to it. Some products contain PABA derivatives, such as padimate O or octyl dimethyl PABA. It is not known if they have the same effects.
The Food and Drug Administration approved Anthelios SX in July 2006. This new sunscreen prevents sunburn and protects against ultraviolet A and B rays. The product contains ecamsule, an ingredient not previously marketed in the United States.
Inorganic formulas contain the UV-blocking pigments zinc oxide or titanium dioxide. Zinc and titanium oxides lie on top of the skin and are not absorbed. They prevent nearly all UVA and UVB rays from reaching the skin. Older sunblocks are white, pasty, and unattractive, but current products use so-called microfine oxides, either zinc (Z-Cote) or titanium. They are transparent and nearly as protective as the older types. Microfine zinc oxide may be more protective and less pasty-colored than microfine titanium oxide.

Inexpensive products work as well as expensive ones with the same ingredients. Unfortunately, there are still no standards for sunscreens, and even those claiming UVA protection may offer very little. In one study, the average UVA protection from a wide range of brands was only 23%. In fact, the average protection of brands not making the claim was 37%!

Organic formulas and inorganic microfine oxides do not protect against visible light, which is a problem for people who have light-sensitive skin conditions, including actinic prurigo, porphyria, and chronic actinic dermatitis. Inorganic sunscreens that protect against visible light and are still cosmetically acceptable are now available in Europe, but not yet in the US.

Calculating the SPF. The sun protection factor (SPF) on all sunscreen labels is a ratio based on the amount of UVB (not UVA) radiation required to turn sunscreen- or sunblock-treated skin red compared to non-treated skin. For instance, people who sunburn in 5 minutes and who want to stay in the sun for 150 minutes might use an SPF 30. The formula would be: 30 (the SPF number) times 5 (minutes to burn) = 150 minutes in the sun.

Protection offered by sunscreens may be classified as follows:

Minimal: SPF 2 to 11.
Moderate: SPF 12 through 29.
High: 30+. (Although some sunscreens claim SPFs higher than 30, the added protection at such higher levels is insignificant.)

SPF Levels by Age Group. Certain groups should have higher or lower SPFs depending on age and other factors:

Although sunscreens are safe in most toddlers and children, they should not be the first and only lines of defense. In fact, experts are worrying that by relying too much on sunscreen and not providing other protective measures, parents may actually be increasing their children's risk for melanoma. All young children should be well covered with clothing, sunglasses, and hats as the first line of defense against sunburn. Children should be kept out of the sun during peak sunlight periods. Sunscreens should not be used on babies younger than 6 months without consulting a doctor.
Older children and adults (even those with darker skin) benefit from using SPFs of 15 and over. Some experts recommend that most people should use SPF 30 on the face and 15 on the body.
Adults who burn easily instead of tanning and anyone with risk factors for skin cancer should use at least SPF 30.

Timing and Amount of Application. You should apply sunscreen or sunblock liberally as follows:

Adults should include sunscreen with a daily skin regimen, even if going outdoors for only a short time.
Apply a large amount to all exposed areas, including ears and feet. To achieve protection as indicated by the sunscreen's SPF, experts recommend half a teaspoon each for the head, neck, and each arm and a teaspoon each for the chest area, the back, and each leg.
Apply initially 30 minutes before venturing outdoors for best results. (This allows time for the sunscreen to be absorbed. Then reapply every 15 - 30 minutes while being in the sunlight.
Also reapply each time after exercise or swimming. (Choose a waterproof or water-resistant formula even if activities don't include swimming. Waterproof formulas last for about 40 minutes in the water, whereas water-resistant formulas last half as long.)
Insect repellents reduce sunscreen SPFs by up to one-third. Use higher SPFs and very liberal application when applying both.

Possible Hazards of Sunscreens, Sun Avoidance, or Both. When used generously and appropriately, sunscreen products and sun avoidance help reduce the severity of many aging skin disorders, including squamous cell cancers. There are certain concerns, however.

Sunscreen Use May Not Protect Against Basal Cell and Melanoma Cancers and May Even Increase the Risk. Although sunscreens help prevent squamous cell carcinomas and other skin disorders, sunscreens do not appear to provide protection against melanoma and some basal cell cancers. In fact, some studies have reported a higher association with sunscreen use and these skin malignancies, though not all studies report such negative results.

The reasons for this possible increased risk are unclear, though some theories include the following:

Until recently, many sunscreens blocked only or mostly UVB rays and not UVA, the more deeply penetrating rays now known to be especially dangerous. Past studies may not have reflected the effects of the broad-spectrum sunscreens now available, which block both UVA and UVB.
People who apply sunscreens may feel safe and stay out longer during high sun-exposure hours than is safe. Even if a person doesn't sunburn, UVA rays can still penetrate the skin and do harm.
People may not put on enough sunscreen. According to a 2002 study, people generally apply only 20 - 60% of the recommended amount, which can provide significantly less protection than the given SPF. (Of note, a 2003 study reported that when applied at the recommended amount, a broad-screen sunscreen prevents DNA damage from UV exposure. However, omitting it even once resulted in significant cell injury.)

Sunscreen Use May Increase the Risk for Health Problems Related to Sunlight Deficiencies. There is some major concern that underexposure to sunlight, due to the use of sunscreens or sun-avoidance measures, may produce other health problems, such as the following:

Vitamin D Deficiency. Vitamin D is found in only a few foods, such as fortified dairy products and fish, but it is produced in the skin in response to UVB sunlight. A medical literature review published in the journal Nutrition and Cancer reported that UVB rays may outshine dietary supplements for building the body's vitamin D reserves. Without an appropriate mix of diet and supplements, vigorous sun protection measures may increase a person's risk for developing vitamin D deficiency. Vitamin D is important for prevention of rickets, osteoporosis, and some cancers, including melanoma. People who need to avoid sunlight and whose diet is low in foods that contain vitamin D should check with their doctor about taking supplements. People with darker skin are at higher risk for deficiencies from sun protection than those with whiter skin. Note: vitamin D is toxic in high doses. Most doctors recommend 200 IU a day (for young adults) to 600 IU a day (above age 70). Doses up to 2,000 IU a day are considered safe. A report analyzing studies of vitamin D supplementation found that people who take vitamin D supplements live longer than those who do not. The researchers looked at 18 studies. They found that participants who received vitamin D supplements were, on average, 7% less likely to die during the study they were in, compared with those receiving "sugar pills."
Other Cancers. Although sunlight is implicated in skin cancers, it is also associated with lower risks for breast, prostate, ovarian, and colon cancers. Some protection against these cancers may be related to vitamin D production by sunlight.
Depression. Many people suffer from SAD (seasonal affective disorder), a form of depression that generally occurs in winter and is associated with exposure to less sunlight.

The bottom line is that some sunlight is important and even necessary for a healthful and high-quality life. Adults may benefit from daily moderate tanning (20 - 30 maximum minutes of exposure during lower-risk hours) over several days to slowly build up pigment in the skin.

Treatment

An increasing number of dermatology patients are looking for a way to improve the appearance of their skin. As a result, more and more products have become available to treat skin wrinkles and blemishes. From vitamins and supplements to exfoliants and chemical peels -- the options can be overwhelming. In some cases, more than one approach may be needed.

Antioxidants are substances that hunt oxygen-free radicals, the unstable particles that can damage cells. Free radicals may also cause sun damage and even skin cancers. Exposure to sunlight depletes antioxidants in the skin, and therefore they must be replaced.

Antioxidant ointments, creams, and lotions ("topical products") may help reduce the risk of wrinkles and protect against sun damage. Unlike sunscreens, they build up in the skin and are not washed away, so the protection may last. Selenium, coenzyme Q10 (CoQ10), and alpha-lipoic acid are types of antioxidants that come in topical form. Many are proving to be very beneficial for the skin.

Vitamin A. Vitamin A is important for skin health. UV radiation produces vitamin A deficiencies in the skin. Topical products containing natural forms of vitamin A (retinol, retinaldehyde) or vitamin A-related products called retinoids (tretinoin, tazarotene) may help repair skin damage due to sunburn and natural aging.

Tretinoin (Retin-A). Tretinoin (known commercially as Retin-A) is the only topical agent approved for treating photoaging and is available in prescription form (Avita, Renova, Differin). The June 2004 issue of Dermatology Surgery reported that tretinoin (0.25% concentration) was an effective and well-tolerated treatment for photodamaged facial skin. This drug produces a rosy glow and reduces fine and large wrinkles, liver spots, and surface roughness. It also may help prevent more serious effects of ultraviolet radiation. Patients may apply tretinoin to the face, neck, chest, hands, and forearms, and should do so at least twice a week. Noticeable improvement takes 2 - 6 months. Because Retin-A increases a person's sensitivity to the sun, patients should apply just a tiny amount at bedtime, and wear sunblock during the day. Patients should also avoid overexposure to the sun. Almost all patients experience redness, scaling, burning, and itching after 2 or 3 days that can last up to 3 months. In women who experience irritation, a daytime moisturizer or low-dose corticosteroid cream, such as 1% hydrocortisone, may help. There is some concern that overuse of high-dose tretinoin may cause excessive skin thinness over time. Studies now suggest that low concentrations (as low as .02%) of tretinoin can produce significant improvements in wrinkles and skin color, with less irritation than the higher doses.
Retinol. Retinol, a natural form of vitamin A, could not, until recently, be used in skin products because it was unstable and easily broken down by UV radiation. Stable preparations are now sold over the counter. In the right concentrations, retinol may be as effective as tretinoin, and studies indicate that it has fewer side effects. An animal study suggests that adding antioxidant creams (such as those containing vitamins C or E) may offer added protection against degradation of retinol, but not tretinoin. The Food and Drug Administration warns that over-the-counter retinol skin products are unregulated. The amount of active ingredients is unknown, and some preparations, in fact, may contain almost no retinol.
Tazarotene. Tazarotene (Tazorac, Zorac, Avage) is a retinoid used for acne and psoriasis. It has now been approved for treating wrinkles, skin discoloration, and blemishes due to photoaging. One short-term study suggested that it may be as effective as tretinoin and even slightly better at high doses. At such high doses, however, it can cause very severe irritation. Redness and peeling may be reduced by administering tretinoin first to get the skin acclimated. A randomized study of 562 patients with facial photodamage found that a daily application of tazarotene 0.1% cream resulted in a minimum 1 grade improvement in fine and coarse wrinkling, uneven skin color, pore size, skin roughness, and overall photodamage. More research is needed to determine if it produces any long-lasting significant benefits.

Warning: Pregnant women and those who may become pregnant should avoid any vitamin A derivative (a product related to vitamin A). For example, oral tretinoin causes birth defects, and women should avoid even topical Retin-A when pregnant or trying to conceive.

Vitamin C. Vitamin C, or ascorbic acid, is a very potent antioxidant. Most studies on the effects of antioxidants on the skin have used this vitamin. In laboratory studies, large amounts of vitamin C reduced skin swelling and protected immune factors from sunlight. It may even promote collagen production. Vitamin C by itself is unstable, but products that solve the delivery problem are now available (such as Cellex-C, Avon's Anew Formula C Treatment Capsules, Physician Elite, and others). More research is needed.

Antioxidants Under Investigation for Skin Care. Other antioxidants are also being investigated for their value in skin protection. Most available brands, however, contain very low concentrations of these antioxidants. In addition, they are also not well absorbed and have a short-term effect. New delivery techniques, however, may prove to offset some of these problems.

Vitamin E. Studies suggest that topical vitamin E, particularly alpha tocopherol cream (a form of vitamin E), decreased skin roughness, length of facial lines, and wrinkle depth. Studies on mice have also reported reductions in UV-induced skin cancer with its use.
Both green and black tea may provide some protection against skin cancers and photoaging. There is also some evidence that pomegranate and soy extracts may help rejuvenate aging skin.
Aloe, ginger, grape seed extract, and coral extracts contain antioxidants and are promoted as being healthy for the skin, although evidence of their effects on wrinkles is weak.

A small study found that taking vitamin C and E supplements by mouth -- at the same time -- may help reduce sunburn, although it doesn't work as well as sunscreen. Taking the vitamins separately did not have any effect. Vitamin C and E are also antioxidants.

One of the basic methods for improving skin and eliminating small wrinkles is exfoliation (also called resurfacing), which is the removal of the top layer of skin to allow regrowth of new skin. Methods for doing this run from simple scrubs to special creams to intensive peeling treatments, including laser resurfacing. People with darker skin are at particularly higher risk for scarring or discoloration with the more powerful exfoliation methods.

Abrasive Scrubs. Scrub gently with a mildly abrasive material and a soap that contains salicylic acid to remove old skin so that new skin can grow. The motion should be perpendicular to the wrinkles. Use textured material or cleansing grains with microbeads. Organic materials, such as loofahs or sea sponges, may harbor bacteria. Avoid cleansing grains that contain pulverized walnut shells and apricot seeds, which can scratch skin on a microscopic level. Cleansing grains with microbeads don't have sharp edges and remove skin without cutting it. Exfoliation using scrubs, however, can worsen certain conditions, such as acne, sensitive skin, or broken blood vessels.

Topical Alpha Hydroxy Acid and Similar Substances. Alpha hydroxy acids (AHA) ease the shedding of dead skin cells and may even stimulate the production of collagen and elastin. Their natural forms are:

Lactic acid (milk)
Glycolic acid (sugar cane)
Malic acid (found in apples and pears)
Citric acid (oranges and lemons)
Tartaric acids (grapes)

Most alpha hydroxy acid products contain glycolic acid. Skin care products are also made from polyhydroxy acids (PHAs) and beta hydroxy acids (BHAs). Research suggests that PHA products may cause less skin irritation than AHA or BHA products.

Acid concentrations in over-the-counter AHA preparations are 2 - 10%. One clinical study suggested that 8% concentrations showed modest skin improvement Some examples include Avon's Anew Intensive Treatment (8% glycolic), Pond's Age Defying Complex (8%), Elizabeth Arden's Alpha-Ceramid Intensive Skin Treatment (3 - 7.5%), and BioMedic's home product (10%). Prescription strength creams contain at least 12% glycolic acid, and glycolic acid peels of 30 - 70% concentration may be administered in a doctor's office at weekly or monthly intervals.

Response to AHA varies, and the treatment is not without risk, particularly in high-concentration products. Side effects from over-the-counter creams, prescription products, and professional AHA peels can include burns, itching, pain, and possibly scarring. Studies also suggest that AHA may increase susceptibility to sun damage, even at concentrations as low as 4%. Such effects can persist up to a week after a person stops using the product. Experts advise that people purchase products with AHA concentrations of 10% or less. Chemical peels of up to 60% are available without prescription on the Internet. Such concentrations are not recommended, except under a doctor's supervision. If any adverse effects occur, stop using the product immediately. Always avoid sunlight or use proper sun protection when using these products.

Copper Peptides. Certain copper-containing compounds may protect skin and help repair it. Note: copper is a toxic metal. When using products containing copper, buy only those that contain peptides (small protein fragments) that bind to copper. Most studies have been conducted on the copper peptide glycyl-l-histidyl-l-lysine:copper (II) or GHK-Cu. It is currently used in a number of products (such as CP Serum, Neutrogena's Visibly Firm, ProCyte's Neova).

Furfuryladenine. Furfuryladenine (Kinetin, Kinerase) is a naturally occurring growth hormone found in plant and animal DNA. It has antioxidant and anti-aging properties. Some small laboratory studies suggest that furfuryladenine may delay the onset and decrease the effects of aging on skin. However, there are no well-conducted human studies to support this suggestion.

Vitamin K. Microsponge-based vitamin K is said to clear bruises spider veins, and other small blood vessel damage. Vitamin K is important for blood clotting.

Moisturizers help prevent dryness, bruising, and tearing. They have no effect on wrinkles by themselves. Moisturizers should be applied while the skin is still damp. These products retain skin moisture in various ways:

Occlusives, such as petroleum jelly, prevent water from evaporating.
Humectants, including glycerin, act by pulling water up to the surface of the skin from deep tissues. People with oily skin generally should use the humectant type.
More powerful compounds, such as monolaurin (Glylorin), contain mixtures of fatty molecules (lipids), which may help restore the skin's natural barriers against moisture loss and damage.

Most moisturizers contain combinations of these compounds. They usually have other ingredients as well, such as alpha hydroxy acids, sunscreens, collagen, and keratin. Collagen and keratin leave a protein film and temporarily stretch the skin. They range widely in price, and a major consumer organization found little difference in general between the more and less expensive products.

The skin under the eyes is very thin and does not produce as much of the protective oils that keep skin soft and supple. Manufacturers market their under-eye gels as being able to reduce puffiness and dark circles. The creams typically work in one of two ways:

By temporarily constricting blood vessels to prevent the build-up of fluids
By firming the skin with an invisible film

Never rub the creams under the eyes, as this may cause more wrinkles to form. Instead, apply these products with a light tapping motion to stimulate the skin.

Cosmetics, if properly applied, can be surprisingly effective in camouflaging the signs of aging skin, including wrinkles and age spots. Moreover, they offer additional benefits by retarding water loss and providing a physical barrier to UV radiation. However, as women age, less is more.

Here are some suggestions for older women:

Moisturizers. Apply moisturizers before foundation. If reddish discoloration is extensive or the skin is sallow, tinted moisturizers may be helpful and can be worn alone or under foundation.

Foundations. Caking on make-up will cause cracks at the wrinkle lines and only increase the appearance of aging. Try to cover large areas of the face with a moderate-coverage foundation that has a matte or semi-matte finish. Facial powder reflects light and thus minimizes wrinkles, but people with dry skin should avoid it.

Correcting Color. When blemishes are especially prominent, applying color correctors under the foundation can be very effective:

Green neutralizers mask red lesions.
Yellow will camouflage dark circles and bruises.
Mauve (a purplish-pink color) helps neutralize sallow skin or yellowish blemishes.
A white, pearled base helps to minimize wrinkles.

Blushes. Blushes and color washes can help conceal the spidery network of dilated capillaries on the nose and cheeks. Powder blushes are preferred because they blend easily on top of foundation.

Eyes. Powder eye shadows applied on top of a moisturizer are better than cream-based shadows. Light-colored shadow, applied along the upper eyelid crease and above the iris (the colored part of the eye) is best for offsetting the appearance of deep-set eyes. You should then apply a slightly deeper shade of the same color to the lower part of the eyelid, and draw it out to the corner.

Lips. A lip-setting cream or facial foundation should be applied before lipstick to help prevent it from bleeding into surrounding wrinkles. Try using a stiff bristle brush instead of a lip pencil. The brush will help keep the lipstick on and prevent bleeding. (Some women use the pencil itself for the full lip, which gives color but appears natural.) Some make-up artists recommend cream lipsticks instead of matte.

The Food and Drug Administration (FDA) does not regulate herbal remedies and dietary supplements. In other words, the manufacturers and distributors of such products do not need FDA approval to sell their products. In addition, any substance that affects the body's chemistry can, like any drug, produce side effects that may be harmful. There have been numerous reported cases of serious and even deadly side effects from herbal products.

Overexposure to sunlight can damage skin. The following natural remedies may cause extra sensitivity to light (photosensitivity):

St. John's wort (Hypericum perforatum) is a popular herbal remedy for depression. People who are sensitive to light should not use it. A case report suggests that St. John's wort may cause skin reactions in patients who have laser treatment.
Kava (Piper methysticum) is an herb used to calm nerves and reduce stress. In addition to photosensitivity, it can cause liver damage.
Yohimbe (Pausinystalia yohimbe) is used to treat erectile dysfunction. Both the herb and the pharmaceutical drug (yohimbine) can cause sensitivity to light.
Essential oils in many botanical aromatherapy products can trigger photosensitivity. Avoid citrus oils (grapefruit, lemon, lime, and orange) as well as bergamot, cumin, ginger, and angelica root oils.

Resurfacing Treatments

There are many choices for skin resurfacing (also called exfoliation), and the patient must consider several different factors that affect the choice. Resurfacing can achieve the following:

Removal of abnormal tissue and rough skin
Stimulation of new skin growth
Stimulation of collagen and elastin production

In addition to determining the skill of the surgeon and the safety of the procedure, the patient must discuss the desired depth of the resurfacing and the capability of each procedure to reach this depth safely. All resurfacing procedures require a healing period afterward, during which the skin is red and sensitive. The deeper the procedure, the higher the risk for complications, including delayed healing, infection, loss of pigment (skin color), and scarring.

If you make the decision to pursue intensive treatments, consider the following factors, among others, and discuss them with your dermatologist or plastic surgeon:

The ability of the procedure to safely reduce wrinkles
The ease and safety record of the procedure
The skill of the doctor
The length of recovery
Possible complications
How long the benefits will last

A person's age also helps determine the procedure:

For people in their 30s, a simple chemical peel is sufficient.
After age 40, people may benefit from collagen or fat implants.
At age 50 and over, plastic surgeons recommend laser resurfacing and customized treatments for individual needs.

In older individuals, combination procedures may be beneficial. Some examples include the following:

Laser surgery may be used for deep lines (such as those around the mouth) and chemical peels used over the rest of the face.
For enhancing the eye by correcting droopy eyelids, bags, and a "sinking" brow, combinations of eyelift (blepharoplasty), Botox, and laser resurfacing may be used.

Chemical peels, also known as chemosurgery, help restore wrinkled, lightly scarred, or blemished facial skin. Much like chemical paint strippers, chemical peels strip off the top layers of skin, and new, younger-looking skin grows back. The procedure is very effective for the upper lip but cannot be performed around the eyes. Partial peels are often done in conjunction with a face-lift. Combinations of the topical antioxidants, such as tretinoin and vitamin C, along with a chemical peel, may be particularly effective.

The Procedure.

A dermatologist applies chemicals to the skin. They include trichloroacetic acid, high concentrations of alpha hydroxy or beta hydroxy acids, or combinations of all three.
In some cases, tretinoin or alpha hydroxy is applied 4 - 6 weeks before, and starting one day after, the peel. Such treatments can enhance the effects of a peel and reduce the risk of discoloration in people at risk for this complication. Tretinoin is being tested as a chemical peel.
A crust or scab generally forms within 24 hours after surgery. You can remove this scab by gently cleansing with soap and water.
The skin takes 6 - 7 days to heal.
After the scab disappears, the visible skin is deep red but gradually lightens as it regenerates.

Complications. Complications include white heads, cold sores, infection, scarring, numbness, and permanent discoloration, particularly in people with darker skin. Refinement of chemical peel techniques are now permitting doctors to reach deeper skin, improvements which make it easier to apply peels to non-facial skin and to individuals with darker skin.

Dermabrasion affects deeper layers of skin than chemical peels, and may be useful for removing disfiguring marks, such as deep acne scars or deep wrinkles. As with chemical peels, it is effective for wrinkles on the upper lip and chin, and cannot be used around the eyes. Some doctors prefer dermabrasion to lasers for skin surfacing of people with darker skin colors.

Standard Dermabrasion. Standard dermabrasion uses a rotating brush that removes the top layers of a person's skin. As with chemical peels, dermabrasion selectively strips away the upper layers of skin, leaving the underlying skin layers exposed. Similar to chemical peels, after the procedure, the treated skin oozes and forms a scab, a reaction that looks and feels uncomfortable, but only temporary. Postoperative care is similar for both procedures.

Microdermabrasion. A gentler variation called microdermabrasion uses very tiny crystals to polish the skin and a vacuum technique to remove them. It has largely replaced the older dermabrasion, and, in fact, was the fourth most common non-surgical cosmetic procedure performed in 2005, with over a million done. Results are similar to light chemical peels. Patients can have this procedure done on their lunch hour and return to work. Only mild redness occurs after treatment, although for best results five or six repetitive treatments are needed every 1 - 2 weeks. To date, overall patient satisfaction has been very high.

Lasers are currently the most effective exfoliation tools for eliminating wrinkles. Their unique advantages over other resurfacing methods are their ability to tighten the skin. A successful procedure can make patients look 10 - 20 years younger, and the results can last up to 10 years.

The procedure is most beneficial for the following areas:

It is best around the mouth and eyes. Recent evidence suggests CO₂ lasers may be even better than dermabrasion for the upper lip.
It is slightly less beneficial for the area around the nose.

Used alone, current laser therapy does not eliminate crow's feet, broken blood vessels, or dark circles under the eye. The evidence of the effects of lasers on acne scars is incomplete.

Standard laser dermabrasion is too harsh for thinner skin layers, such as on the neck. Newer and gentler laser techniques, however, stimulate collagen without removing skin layers, and may prove to be useful for necklines.

The Laser Resurfacing Procedure. In general the procedure works in the following way:

Laser pulses penetrate the skin quickly, vaporizing water and surface skin without damaging the deeper layers, allowing new top skin to grow.
In addition, the laser delivers enough heat to shorten collagen fibers, restoring some elasticity to the skin.

Choice of Lasers. The lasers used depend on skin type and severity of the condition. Some of the more common laser types are:

The carbon dioxide (CO₂) laser. This is the most powerful laser treatment and is used for deep wrinkles and skin imperfections. People who have had silicone injections should not have CO₂ procedures, which can burn and scar the skin over the implanted area.
The erbium: YAG (Er:YAG). This laser is gentler than the CO₂ laser, and is effective for mild wrinkles and for providing a smooth skin texture. It has a shorter recovery time. Some experts have even found the YAG laser as effective in removing deep wrinkles as CO₂ when used to sufficient depth. A variable pulse YAG laser can shift between pulses that destroy skin tissue to those that heat the skin. This process effectively resurfaces the skin with fewer side effects than CO₂ laser therapy.
Pulsed dye laser. Pulsed dye laser uses yellow light, which is easily absorbed by hemoglobin, the molecule that gives blood its red color. Pulsed dye laser treatments are used to treat skin blemishes that are due to blood vessel abnormalities, such as port-wine stains.

A gentle laser procedure called non-ablative laser resurfacing (NLite), also called photorejuvenation, is now approved for the treatment of all facial wrinkles. The procedure uses light energy to gently stimulate new collagen, and possibly elastin production, without removing the skin tissue itself. Its effects are less pronounced than those of other laser procedures. However, because it does not injure the external layers of skin, it can be used on delicate skin areas, such as the neck and around the eyes. It also causes very little irritation afterward.

Some surgeons are using combination techniques that employ more than one laser technology in one session, to achieve different effects. For example, one combination technique uses CO₂, YAG, pulsed-dye laser, and one other laser technology to both improve wrinkles and clear under-eye dark circles and acne scarring. Pretreatment with botulinum (Botox) injections before laser resurfacing significantly improved the treatment of crow's feet in one study.

Post-Procedure Recovery. The procedure itself is relatively painless, but the redness and irritation that occur during the healing process can be severe. Non-ablative laser resurfacing does not have the same severe after-effects as other laser treatments. For 8 - 9 days, the face looks skinned and swollen, and requires continuous moisturizing. Some doctors suggest that people with very sensitive skin, who cannot tolerate the necessary medications and lubricants, should avoid laser resurfacing. Redness and sensitivity can persist for 1 - 4 months. The patient must stay out of the sun as much as possible during this time, and should always avoid sunbathing and damaging their skin again. Early research suggests that silicone dressings may reduce post-procedure pain and crusting.

Complications. Scarring and infections can occur in about 1% of procedures. The risk of complications depends on the experience of the surgeon. People with a history of herpes simplex may experience flare-ups of fever, facial pain, and flu-like symptoms for 5 or 6 days after the procedure. In addition, people with darker skin may wish to avoid the procedure, because it can cause unpredictable and dramatic lightening of the skin.

A new skin rejuvenation technology, called Plasma Skin Resurfacing, or Portrait Plasma, was introduced in February 2005. The technology uses plasma energy (heat and light energy) to rejuvenate the skin from the deeper layers outwards. While new skin regenerates, the outer layers of the skin act as a natural bandage. When the outer layers peel off in the week after treatment, the new skin emerges. The process prevents or minimizes the raw appearance that follows laser treatments. This system uses radio waves to "excite" nitrogen gas, resulting in the release of energy. According to the manufacturer, skin regeneration using the Portrait Plasma system is rapid, and satisfaction with the procedure appears high. Long-term follow-up studies are not available yet for this new method. In 2006, the Food and Drug Administration approved this method for the treatment of wrinkles on other areas of the body, besides the face.

Cold Ablation. Cold ablation, called coblation for short, delivers saline (salt water) to the skin, through which a cool electric current is passed. A subsequent reaction heats and vaporizes the top shallow layer of skin. The procedure is very specific and appears to minimize any damage to other areas of the skin.

Radiofrequency Resurfacing. A promising technique uses low radiowave energy to resurface the skin. Preliminary research indicates that this procedure may eventually be as effective as laser surgery in reducing severe wrinkles around the eyes and mouth, with minimal pain and a shorter recovery time. In one study, one radiofrequency treatment with only a skin anesthetic resulted in tighter facial skin for 14 out of 15 patients within 12 weeks. All but one patient returned to normal activity immediately afterward. A small clinical trial published in Dermatology Surgery found that a noninvasive radiofrequency technique called NARF safely and effectively improved drooping lower eyelids.

Intense Pulsed Light. Intense pulsed light (IPL) uses filters to deliver different wavelengths of light. Doctors use it to treat a number of photoaging skin problems, and it appears to have long-term effects. Typically, four to six treatments are performed over a four-month period. Each treatment takes 15 - 20 minutes. Unlike laser light, which uses one color wavelength (such as green or red), intense pulsed light starts with a full spectrum of light. It then allows the doctor to selectively block off specific wavelengths, depending on how shallow or deep the procedure should go. IPL machines are less expensive and safer than lasers.

Implant Procedures

Implants, also called injectable fillers, are becoming a common means of erasing wrinkles and folds. Several materials are being used for deep wrinkles, depression under the eyes, lip enhancements, and acne scars.

After being banned from the market in 1992, silicone is making a comeback in research settings as a potential permanent wrinkle eraser. Scientists are looking into a new microdroplet technique (the use of very small drops) combined with purified silicone as a way to eliminate any danger. The past problems with silicone occurred when it was mixed with a foreign substance, like mineral oil, or when it was injected in large doses.

Most implants to date, however, are not completely satisfactory. Collagen implants and biologic fillers from animal, bacterial, or human sources do not provide long-lasting benefits. Synthetic fillers are permanent but may cause an allergic reaction, which can lead to chronic problems. Such reactions are rare, but they can be painful and unattractive.

The U.S. Food and Drug Administration (FDA) approved the Juvéderm product line in June 2006. Juvéderm is an injectable treatment of moderate-to-severe facial wrinkles and folds. Juvéderm products are gels made from hyaluronic acid. They are injected into the face. Doctors report good results after a single treatment with Juvéderm, and the results last for at least 6 months.


Name and Material Used	Procedure	Specific Areas Affected	Benefits	Drawbacks
Collagen implants. Collagen is the protein that forms the structures in the body (such as skin, bones, cartilage). The implant procedure has typically used bovine (cow) collagen. A form of human collagen (CosmoDerm, CosmoPlast) has now been approved.	Injected into target wrinkles with needle and syringe. Several weeks after injection, cow collagen breaks down and is replaced by newly created human collagen.	Wrinkles around the eyes and mouth. It is used to give lips greater fullness.	Very simple with faster recovery than many other implant techniques.	Wrinkles form again, and require repeat treatments 3 - 12 months later. Rarely, severe allergic reactions occur. Should not be used by children, pregnant women, and people with a history of autoimmune disease.
Microlipoinjection. Fat tissue from the patient's own thigh or abdomen.	Injected into target wrinkles with needle and syringe.	Deep wrinkles around the nose and mouth, folds in the forehead, and wrinkles on the hands.	No allergic or immune reaction because substance is patient's own fat.	Body eventually absorbs the fat, resulting in a need for multiple injections. Some studies suggest that 70% of the fat may still be in place after at least a year.
Gore-Tex. Highly porous (full of tiny holes) and inert (not chemically active) synthetic material.	Requires some surgery. Tiny patches are inserted under the skin to fill out wrinkles. Skin cells and blood vessels pass through the porous material easily, reducing the risk of severe irritation.	Deep wrinkles.	Material does not break down.	Possible scarring from surgical procedure. Allergic reactions are rare but can occur even with chemically inactive materials.
Artecoll. Contains PMMA, or polymethylmethacrylate, an inert substance, enclosed in tiny droplets of natural collagen.	Material is injected. Body absorbs collagen. PMMA remains and stimulates new collagen growth.	Deep wrinkles.	Although part of the implant is a natural collagen implant, it does not degrade as quickly as a full collagen implant.	Repeat treatments may still be needed. Possible allergic reaction.
Hyaluronic acid. Natural (non-animal) substance acts like a molecular sponge to absorb water. The FDA approved Restylane in 2003, Captiva, Hylaform-Plus, and Hylaform in 2004, and Juvéderm in 2006.	Gel is injected under the skin.	Moderate-to-severe wrinkles.	Low risk for allergic reaction. May last longer than cow collagen.	Repeat treatments needed.
Poly-L-lactic acid. Synthetic polymer. Approved in US as Sculpta. Approved in other countries as New-Fill.	Material is injected under the skin.	Approved in U.S. only for patients with facial fat loss due to HIV. Approved in other countries for wrinkles.	Low risk of allergies. Treatment effects can last 18 - 24 months.	Doctors require special training.

The popularity of Botox injections has skyrocketed in the United States. Between 2004 and 2005, the number of procedures performed jumped 16 percent. Botox injection was the number one non-surgical cosmetic procedure in 2005, with more than 3.2 million injections. Botulinum, the deadly toxin found in uncooked foods, is also a powerful muscle-relaxant. Tiny amounts of a purified form (Botox) are injected into wrinkles to relax the surrounding muscles. It may benefit forehead and frown lines, crow's feet, lower eyelids, lines on the side of the nose, and the area between the upper lip and the nose. It is also useful for treating involuntary muscle movements that can occur after a face-lift.

The injections need to be repeated every few months, since the effects wear off. The treatment decreases the ability to frown or squint and may cause the corners of the mouth to turn down. When used for areas around eyes, it produces a rounder appearance afterward, which patients should be aware of before they undertake the procedure.

The drug does not cross the blood-brain barrier, and, to date, the only side effects are temporary muscle weakness near the injection site. Although there have been some reports that Botox can reduce migraine and tension headaches, Botox also causes headaches in about 1% of cases. In some cases, the headaches can be very severe and long lasting (from 8 days to a month). Some researchers suggest that either a contaminated batch of Botox or a specific injection technique may be the cause, but additional investigation is needed.

Plastic Surgery

In 2005, there were over 2.1 million cosmetic surgeries, up 1% from the year before. Most of these surgeries were liposuction and breast surgeries. However, over 200,000 each of eyelid and nose surgeries were performed. Facial plastic surgeries range from being fairly minimal, such as a brow lift, to a full face-lift.

Several face-lift procedures (called rhytidectomies) are available. Face-lifts can provide individuals with a more youthful look. The degree of improvement, however, depends on many factors, including age, bone structure, skin type, and personal habits, such as smoking and sunbathing.

The Procedure. When a face-lift is a relatively simple procedure, it can take about 2 hours under local anesthetic in a doctor's office. Complicated face-lifts are done under general anesthesia in a hospital and can take 3 - 6 hours. The face-lift procedure may be one of the following:

Superficial musculoaponeurotic system (SMAS) is the most common face-lift procedure. The surgeon makes an incision at the hairline and separates the skin from the underlying tissue and muscles. The muscles are tightened and excess fat and tissue, such as fat under the chin and neck, are removed.
The endoscopic subperiosteal or subgaleal face-lift is a less invasive surgical technique. The surgeon raises facial structures rather than cutting away flaps of skin. Only a few half-inch incisions are made, and scarring is minimal. Not all individuals are candidates for this procedure, however.

Neither SMAS nor the endoscopic version is effective for the middle part of the face, particularly the deep lines (naso-labial folds) that run down from the nose beside the mouth. Some time after the SMAS face-lift, the upper face begins to age again while the lower area keeps its shape, causing the face to look imbalanced. Researchers are looking at other approaches, such as one called composite face-lift, that lift most muscles in the face.

Recovery Process. Recovery normally lasts from several weeks to several months. Swelling and discoloration are common. Some patients report tingling or numbing sensations after surgery. These sensations generally decrease as damaged nerves regenerate.

Complications. A face-lift is not without risks. A postsurgical hematoma is a collection of blood that can occur after a face-lift. In one study, major hematomas occurred in 2.2% of patients and minor hematomas in 6.65% of patients. They generally develop within 2 weeks of the surgery and require draining. Even minor hematomas need fast treatment to prevent greater complications. Such complications can include infection, changes in skin color, fluid buildup, and prolonged recovery time.

Other less common complications may include the following:

Infection
Excessive bleeding
Imbalanced facial muscles
Delayed healing
Scarring
Permanent injury to the nerves that control facial movements

These complications are rare, particularly with a skilled surgeon, but the more complex the face-lifts, the greater the risk.

Blepharoplasty. Blepharoplasty is the primary surgical procedure for eye lifts. Results usually last 5 -10 years. Although simple, it has potential complications, including permanent difficulty in closing the eyes or making a stern expression. Newer techniques, however, are preventing this complication. Assuming the surgeon is experienced, laser surgery is now preferred to the standard surgical scalpel approach. Laser surgery reduces bleeding and bruising, and both the operation and recovery are faster. Temporary blurred or double vision is common. More serious complications include infection, bleeding, dry eyes, difficulty in closing the eyes, and pulling down of the lower lids. Rare cases of blindness have been reported.

Transconjunctival Upper Blepharoplasty. An innovative procedure called transconjunctival upper blepharoplasty removes fat from the membrane that lines the eyelids (the conjunctiva) and is an effective technique for treating both the upper and lower eyelids. Unlike traditional blepharoplasty, this procedure does not cause scarring in the nasal area. In patients who have scars from previous surgeries, transconjunctival removal of fat can also make existing scars less obvious. Long-term side effects and effectiveness of this procedure have not been studied.

Laser Liposculpture and Platysma Resurfacing. A procedure called laser neck and jowl liposculpture and platysma resurfacing may prove to be an alternative to face-lifts. The procedure requires only a one-inch incision under the chin and removing excess fat. After the fat is removed, the surgeon tightens the platysma, the thin muscular sheet under the skin of the neck, which improves the shape of the neck. Only local anesthetic is needed, and the patient can return to normal activities in 2 days. The patient's skin should be elastic enough to be able to reform without sagging.

Doing Drugstore: Maybelline Instant Age Rewind Double Face Perfector

BellaSugar — Mon, 24 Nov 2008 11:01:54 -0800

When YSL Touche Éclat debuted in 1992, beauty editors began raving about the highlighter's ability to brighten a dull complexion. Sixteen years later, it's still a best-selling item, even spawning a version for men last month. It's one of the few makeup items I'll splurge on, but after my most recent pen started to smell bad after a few weeks, I resented having paid $39.50 for it.

Off to the drugstore, then. Clearly angling for the Touche Éclat market, Maybelline's Instant Age Rewind Double Face Perfector ($6.38) combines a concealer and highlighter in one double-ended wand. First things first: The concealer is just so-so. It's not as though I'm Uncle Fester or anything, but I need a bit more spackle than what this creamy, light coverage provides. But the highlighter is pretty great; you brush it on underneath your eyes, along the bridge of the nose, along cheekbones, and bam! Subtly brighter, less tired-looking skin. Will I give up Touche Éclat? No, but especially while the economy is rough, I'll pick up Maybelline again.

Drug Approval

In 2007, the FDA approved risperidone (Risperdal) for short-term treatment of manic or mixed episodes of bipolar I disorder in children ages 10 - 17. Risperidone (an atypical antipsychotic) and lithium (a mood stabilizer) are the two drugs currently approved for treating pediatric patients with bipolar disorder.

Drug Warnings

Olanzapine (Zyprexa, Symbex) causes a greater risk for high blood sugar than other atypical antipsychotics, according to updated information added to the drug’s warning label. Olanzapine also causes weight gain and can increase the risk for unhealthy cholesterol levels.
All atypical antipsychotics increase the risk for diabetes. Patients who take these drugs should receive regular screenings for changes in blood sugar levels. Patients should also have their cholesterol levels monitored.

Bipolar Disorder in Children and Adolescents

Diagnoses of bipolar disorder in children have increased 40-fold in the past decade, according to an analysis in the Archives of General Psychiatry. There is debate whether bipolar disorder in children was under-diagnosed in the past or is being over-diagnosed now.
Bipolar symptoms in children differ from those of adults, with some symptoms overlapping with behavioral and conduct disorders. New guidelines from the American Academy of Child and Adolescent Psychiatry (AACP) caution that a diagnosis of bipolar disorder must be carefully made, especially considering the risks associated with drug therapy. The AACP also advises that there are currently no established criteria for diagnosing bipolar disorder in preschoolers.

Bipolar Depression

The antidepressants bupropion (Wellbutin) and paroxetine (Paxil) do not increase the risk for mania, but neither do they help ease depression any more than mood stabilizers, suggests a 2007 study in the New England Journal of Medicine.
Intensive psychotherapy in combination with medication can help improve depression outcomes, indicates a 2007 study in the Archives of General Psychiatry.

Introduction

Bipolar disorder, or manic-depressive illness, is characterized by moods that swing between two opposite poles:

Periods of mania with exaggerated euphoria, irritability, or both
Episodes of depression

Although chemical imbalances in the brain are a key component of bipolar disorder, it is a complex condition that involves genetic, environmental, and other factors.

Bipolar disorder is classified according to the pattern and severity of the symptoms as bipolar disorder I, bipolar disorder II, or cyclothymic disorder. Patients with one type may develop another. Nevertheless, they are distinct enough to merit separate classifications, and some experts believe these conditions are actually separate disorders with different biologic factors that account for their differences.

Bipolar Disorder I. Bipolar disorder I is characterized by at least one manic episode, with or without major depression, that lasts for at least 7 days. In 60 - 70% of cases, manic episodes precede or follow depressive episodes in a regular pattern. Episodes are more acute and severe than in the other two categories.

Without treatment, patients average four episodes of dysregulated mood each year. With mania, either euphoria or irritability may mark the phase. In addition, there are significant negative effects (such as sexual recklessness, excessive and impulsive shopping, and sudden traveling) on a patient's social life, performance at work, or both. Untreated mania lasts at least a week, and it can last for months. Typically, depressive episodes tend to last 6 - 12 months, if left untreated.

Bipolar Disorder II and Hypomania. Bipolar disorder II is characterized by episodes of predominantly depressive symptoms, with occasional episodes of hypomania, which last for at least 4 days. Hypomania is similar to mania, but the symptoms (typically euphoria) are less severe and do not last as long.

Patients do not experience manic or mixed episodes, and most return to fully functional levels between episodes. However, bipolar II patients have a more chronic course, significantly more depressive episodes, and shorter periods of being well between episodes than patients with type I have. It is highly associated with the risk for suicide.

Cyclothymic Disorder. While cyclothymic disorder is not as severe as either bipolar disorder II or I, the condition is more chronic. Hypomanic symptoms tend toward irritability as compared to the more euphoric symptoms of bipolar II. (One report, in fact, referred to these patients as having "darker" natures, while bipolar II patients were "sunnier.")

The disorder lasts at least 2 years, with single episodes persisting for more than 2 months. Cyclothymic disorder may be a precursor to full-blown bipolar disorder in some people or it may continue as a low-grade chronic condition.

Symptoms of the Depression Phase. The symptoms of depression experienced in bipolar disorder are almost identical to those of major depression, the primary form of unipolar depressive disorder. They include:

Sad mood
Fatigue or loss of energy
Sleep problems such as insomnia, excessive sleeping, or shallow sleep with frequent awakenings
Appetite changes
Diminished ability to concentrate or to make decisions
Agitation or markedly sedentary behavior
Feelings of guilt, pessimism, helplessness, or low self-esteem
Loss of interest or pleasure in life
Thoughts of, or attempts at, suicide

Distinguishing Between Unipolar and Bipolar Depression. It is often difficult to differentiate between unipolar and bipolar depression, particularly in patients with bipolar II disorder. They may differ in the following ways:

Bipolar depression typically lasts 2 - 3 months -- not as long as in major depression (although left untreated some bipolar disorder episodes can last 6 - 12 months or longer).
People with unipolar depression can still experience a variety of other moods, but none meet the criteria for a manic state.
Depressive symptoms in those with bipolar disorder tend to vary. For example, some patients experience increased sleep, gain weight, and feel a heaviness and slowness in their bodies. Other patients with bipolar depression experience impaired sleep, but unlike patients with unipolar depression, they do not feel sleepy the next day.
Bipolar depressive episodes tend to develop more gradually than do those caused by major depression.

Symptoms of the Acute Manic Phase. The acute pure manic phase is always characterized by mood elevation, presented in the following ways:

Exaggerated euphoria (a feeling of great happiness or well-being)
Irritability
Both euphoria and irritability

The episode lasts for at least few days but, in some cases, the episode may last weeks or even months and may be severe enough to require hospitalization.

Other symptoms must also be present to make a diagnosis. Some mental health professionals use the mnemonic device DIGFAST to identify them. In general, for a diagnosis of mania, a patient must have experienced either euphoria with three DIGFAST symptoms or irritability with four of these symptoms:

D. Distractibility. This is the most common symptom, and it is usually characterized by the inability to pay attention to any activity for very long.
I. Insomnia in mania typically means having high energy and requiring less sleep. (This differs from insomnia in depression, in which the patient has low energy plus an inability to sleep.)
G. Grandiosity. Patients with this symptom have an inflated sense of themselves, which, in severe cases, can be delusional. Close to 60% of all manic patients experience feelings of being all-powerful. Sometimes they feel that they are godlike or have celebrity status.
F. Flight of ideas. Thoughts literally race.
A. Activity. The patient may show an increase in intensity in goal-directed activities, which are related to social behavior, sexual activity, work or school.
S. Speech. The patient may talk excessively.
T. Thoughtlessness. Excessive involvement in high-risk activities is present (such as unrestrained shopping, promiscuity). Mood disturbance may be severe enough to damage one's job or social functioning or one's relationships with others. Some patients require hospitalization to prevent harm to others or to themselves.

Some patients with bipolar I may experience psychotic symptoms, including thought disorders, hallucinations, and catatonia (a state in which the patient goes into a stupor for long periods, which may give way to short periods of extreme excitement).

Hypomania. With hypomania the symptoms of mania are milder and of shorter duration (but they last at least 4 days). They do not affect social or work life as dramatically.

Mixed Mania State Symptoms. Mixed mania (also called mixed episodes or dysphoric mania) are manic episodes that also have a depressive component. In such a state, mania is present to a significant degree, but depression is present most of the day and nearly every day. Such mixed symptoms occur for at least a week.

Depressive Mixed State Symptoms. Depressive mixed state is characterized by major depression as the primary emotional state with manic features (such as irritability, distractibility, and racing thoughts). Such patients may receive an inaccurate diagnosis of unipolar depression.

Risk Factors

Between 1 - 2 million Americans may suffer from bipolar disorder. Researchers estimate that about 1% of Americans experience bipolar disorder during the course of their lifetime, but some studies indicate that prevalence may be as high as 4%. There is differing opinion on how to diagnose and categorize bipolar symptoms, which affects these estimates. The majority of people with bipolar disorder also have other psychiatric disorders, particularly anxiety and substance abuse.

Bipolar disorder affects both sexes equally, but there is a higher incidence of rapid cycling, mixed states, and cyclothymia in women. Early-onset bipolar disorder tends to occur more frequently in men and it is associated with a more severe condition. Men with bipolar disorder also tend to have higher rates of substance abuse (drugs, alcohol) than women.

Bipolar disorder frequently occurs within families, although genetic factors account for only about 60% of cases. Family members of patients with bipolar disorder also have a higher than average incidence of other psychiatric problems. They include schizophrenia, schizoaffective disorder, anxiety disorders, ADHD, and major depression.

Causes

No single cause may ever be found for bipolar disorder. Instead, a combination of biologic, genetic, and environmental factors appears to trigger and perpetuate the chemical imbalances in the brain that shape this complex disorder. Biologic factors observed or considered in bipolar disorder, as detected by use of imaging scans and other tests, include:

Oversecretion of cortisol, a stress hormone
Excessive influx of calcium into brain cells
Abnormal hyperactivity in parts of the brain associated with emotion and movement coordination
Low activity in parts of the brain associated with concentration, attention, inhibition, and judgment
A superfast "biologic clock"

The so-called biologic clock is a tiny cluster of nerves called the supra chiasmatic nucleus, or SCN. The SCN is located in the center of the brain in the hypothalamus region. It regulates a person's circadian rhythm, the daily cycle of life, which influences sleeping and waking.

The genetics of bipolar disorder are the most intensively studied of all psychiatric diseases. Multiple genes, involving several chromosomes, have been linked to its development. Bipolar disorder also may share these genetic factors with other disorders, including schizophrenia, epilepsy, and panic disorder. It is not clear if some of these disorders are variations of a single disease or separate disorders.

Bipolar Disorder and Schizophrenia. Researchers have been investigating whether common biologic factors are involved with schizophrenia, severe bipolar disorder, and other psychoses. Schizophrenia and bipolar disorder often show up in the same family. Researchers are identifying a number of common genetic and biologic pathways that they both share. Bipolar Disorder and Epilepsy. Neurotransmitters called gamma aminobutyric acid (GABA) and norepinephrine have been implicated in mania:

GABA helps prevent nerve cells from over-firing
Norepinephrine is a hormone that involves stress

Some research has associated similar biologic mechanisms in patients with epilepsy and bipolar disorder. As in epilepsy, the more episodes a bipolar disorder patient experiences early in the course of the disease, the more frequent and severe later episodes will be. Antiseizure drugs, in fact, can play an important role in the treatment of bipolar disorder.

Panic Disorder and Bipolar Disorder. Researchers are also studying the common biologic and genetic factors between panic disorder and bipolar disorder. While specific genes have not yet been identified, some researchers studying these illnesses now believe that they may represent different forms of a shared, complex condition.

Prognosis

Bipolar disorder can be severe and long-term, or it can be mild with infrequent episodes. Patients with the disease may experience symptoms in very different ways. A typical bipolar disorder patient averages 8 - 10 manic or depressive episodes over a lifetime. However, some people experience more and some fewer episodes.

Typical Bipolar Cycles. In most cases of bipolar disorder, the depressive phases far outnumber manic phases, and the cycles of mania and depression are neither regular nor predictable. Many patients experience mixed mania, or a mixed state, in which both mania and depression coexist for at least 7 days.

Rapid Cycling. About 15% of patients with the disorder have a temporary, complicated phase known as rapid cycling. With this phase the manic and depressive episodes alternate at least four times a year and, in severe cases, can even progress to several cycles a day. Rapid cycling tends to occur more often in women and in those with bipolar II. Typically, rapid cycling starts in the depressive phase, and frequent and severe episodes of depression may be the hallmark of this event. This phase is difficult to treat, particularly since antidepressants can trigger the switch to mania and set up a cyclical pattern.

Differences Between Children and Adults. Research suggests that symptoms of bipolar disorder in children and adolescents differ from those of adults. While adults with bipolar disorder usually have distinct and persistent periods of mania and depression, children with bipolar disorder fluctuate rapidly in their mood and behavior. Mania in children is characterized by irritability and belligerence whereas adults tend to experience euphoria. Children with bipolar depression are frequently angry and restless, and may have additional mood and behavioral disorders such as anxiety, attention deficit hyperactivity disorder, conduct disorder, and substance abuse problems.

Medical evidence has shown that patients with bipolar disorder have higher death rates from suicide, heart problems, and death from all causes than those in the general population. Patients who get treatment, however, experience great improvement in survival rates, including deaths from suicide and heart disease.

Bipolar disorder usually first occurs between the ages of 15 - 30 years, with an average age of onset at 25 years. However, bipolar disorder can affect people of all ages, including children. Bipolar disorder that occurs late in life often accompanies medical and neurological problems (particularly cerebrovascular disease, such as stroke). It is less likely to be associated with a family history of the disorder than earlier-onset bipolar disorder.

Patients with bipolar disorder, especially type II or cyclothymic disorder, have frequent episodes of major depression. Anxiety disorders also commonly coexist in these patients. For example, the occurrence of panic disorder in patients with bipolar disorder is 26 times that of the general population. Patients with bipolar disorder, particularly those with type II, are also subject to phobias. In one study, the presence of anxiety disorders was also associated with longer and more severe bipolar depressive episodes and with a higher risk for suicide.

Symptoms of bipolar disorder in children are often confused with attention-deficit hyperactivity disorder (ADHD). Furthermore, the two conditions can coincide. In one study, 65% of adolescents with bipolar disorder met criteria for ADHD. The risk for both diagnoses is highest in white males. Symptoms are also more severe in people with both conditions. Some researchers believe that many of these disorders may actually be variations of a single disease.

The risk for suicide is very high in patients who suffer from bipolar disorder and who do not receive medical attention. Between 10 - 15% of patients with bipolar disorder I commit suicide, with the risks being highest during episodes of depression or mixed mania (simultaneous depression and mania). Some studies suggest that the risk for suicide in patients with bipolar disorder II is even higher than it is for those with bipolar disorder I or major depressive disorder. Patients who also suffer from an anxiety disorder are also at greater risk for suicide. (Rapid cycling, although a more severe variation of bipolar disorder, does not appear to increase the suicide risk in patients with bipolar disorder.)

Many pre- and early adolescent children with bipolar disorder are more severely ill than are adults with the disease, and the risk for suicide is high. They have a higher risk for mixed mania, multiple and frequent cycles, and a long duration of illness without well periods.

Studies suggest that patients with bipolar disorder may have varying degrees of problems with short- and long-term memory, speed of information processing, and mental flexibility. Such problems persist even between episodes. They tend to be more severe when a person has more manic episodes. Medications used for bipolar disorder could be responsible for some of these abnormalities, although some evidence suggests that such traits may have a biologic basis. These mental difficulties may make it harder for these patients to comply with medications or to participate in complex psychotherapies.

A small percentage of bipolar disorder patients demonstrate heightened productivity or creativity during manic phases. More often, however, the distorted thinking and impaired judgment that are characteristic of manic episodes can lead to dangerous behavior, including:

Spending money with reckless abandon, causing financial ruin in some cases
Angry, paranoid, and even violent behaviors
Openly promiscuous behavior

Such behaviors are often followed by low self-esteem and guilt, which are experienced during the depressed phases. During all stages of the illness, patients need to be reminded that the mood disturbance will pass and that its severity can be diminished by treatment.

Cigarette smoking is prevalent among patients with bipolar disorder, particularly those who have frequent or severe psychotic symptoms. Some experts speculate that, as in schizophrenia, nicotine use may be a form of self-medication because of its specific effects on the brain.

Up to 60% of patients with bipolar disorder abuse other substances (most commonly alcohol, followed by marijuana or cocaine) at some point in the course of their illness.

The following are risk factors for alcoholism and substance abuse in patients with bipolar disorder:

Having mixed-state episodes rather than ones of pure mania
Being a man with bipolar disorder

Patients do not manifest their negative behaviors (such as spending sprees or even becoming verbally or physically aggressive) in a vacuum. They have a direct effect on others around them. It is very difficult for even the most loving of families or caregivers to be objective and consistently sympathetic with an individual who periodically and unexpectedly creates chaos around them.

Many patients and their families find it difficult to accept that these episodes are part of an illness and not simply extreme, but normal, characteristics. Such denial is often strengthened by patients who are highly articulate and deliberate, and who can intelligently justify their destructive behavior, not only to others, but also to themselves.

Family members may also feel socially alienated by the fact of having a relative with mental illness, and feel forced to conceal this information from acquaintances.

The economic burden of bipolar disorder is significant. It is estimated that the disorder costs the U.S. workplace about $14.1 billion annually in lost productivity, mostly due to poor functioning on the job. According to a 2006 study sponsored by the U.S. National Institute of Mental Health, bipolar disorder accounts for twice as much lost productivity as major depressive disorder (MDD), despite the fact that MDD is more prevalent. Each worker with bipolar disorder loses about 66 workdays a year compared with 27 workdays a year for workers with MDD. Research suggests that bipolar disorder’s depressive episodes impair productivity more than its manic episodes.

People with mental illness have a higher incidence of many medical conditions, including heart disease, asthma and other lung problems, gastrointestinal disorders, skin infections, diabetes, hypertension, migraine headaches, hypothyroidism, and cancer. Patients with bipolar disorder are also less likely to receive medical care than people without mental disorders. Substance abuse, including smoking, alcoholism, and drug abuse, also contributes to many of these problems as well as reduced access to care. Medications used for bipolar disorder can also increase the risk for medical problems.

However, people with bipolar disorder and other mental illness have a higher risk for a number of these conditions independent of these factors.

Diabetes. Diabetes is diagnosed almost three times more often in people with bipolar disorder than it is in the general population. Many patients with bipolar disorder are overweight, with about 25% meeting the criteria for obesity. Being overweight is a significant risk factor for diabetes and so it may be the common factor in both diseases. Drugs used to treat bipolar can also cause weight gain and diabetes. Common genetic factors in diabetes and bipolar disorder may cause a rare disorder called Wolfram syndrome and other problems with carbohydrate metabolism.

High Blood Pressure. Patients with bipolar disorder may be at a higher risk for high blood pressure (hypertension) than patients without the disorder. The high prevalence of hypertension among patients with bipolar disorder may also account for their greater risk for illness and death from heart-related conditions.

Migraine Headaches. Migraines are common in patients with a number of mental illnesses, but they are particularly common among patients with bipolar II disorder. Patients with bipolar II suffer from migraine more frequently than patients with bipolar I, suggesting that different biologic factors may be involved with each bipolar form.

Hypothyroidism. Hypothyroidism (low thyroid levels) is a common side effect of lithium, the standard treatment for bipolar. However, evidence also suggests that patients, particularly women, may be at higher risk for low thyroid levels regardless of which medications they use. Hypothyroidism may, in fact, be a risk factor for bipolar disorder in some patients.

Diagnosis

Bipolar disorder is more common than previously thought, but this illness, particularly bipolar disorder II, is still poorly recognized in the family-practice setting. It is estimated that only a third of affected people are accurately diagnosed.

When making a diagnosis of bipolar disorder, it is important that the doctor rule out other conditions that may be causing symptoms of bipolar disorder.

Distinguishing Mania from Normal Euphoria or Joy. A major difficulty with a diagnosis of bipolar disorder is the tendency for a patient to be unable to recognize his or her own condition, particularly when in the manic state. The patient often denies their symptoms, which may be perceived as positive feelings. The doctor should take a careful and complete history of any and all episodes of depression, mania, or both. Hypomania, the less severe variant of mania, may be particularly difficult to distinguish from normal joy or euphoria. It can often be distinguished by the following characteristics:

Hypomania persists for at least 4 days
Patients with hypomania are easily distracted and overly talkative
Patients with hypomania have difficulty functioning

Distinguishing Unipolar from Bipolar Depression. People with bipolar disorder are more likely to seek help because of a depressive episode and may not have a manic episode until they have experienced three or more depressive episodes. In such cases, the condition is often diagnosed as major depression. An accurate diagnosis is important because patients with bipolar disorder who are inappropriately medicated solely with antidepressants have a higher incidence of rehospitalization than do other bipolar disorder patients.

Bipolar disorder should be suspected in patients who have been treated for depression and who had a fast and good response, followed by the return of depression and failure to respond to other antidepressant treatment.

A family history of manic-depressive illness may make a doctor suspicious, but a diagnosis of bipolar disorder cannot be established until a manic or hypomanic episode has occurred. Patients with bipolar II disorder and those with depressive mixed state are most likely to be misdiagnosed with depression.

Attention Deficit Hyperactive Disorder (ADHD). Children or adolescents with bipolar disorder may be inappropriately diagnosed with attention-deficit hyperactivity disorder. ADHD and bipolar disorder often cause inattention and distractibility, and the two disorders may be difficult to distinguish, particularly in children. In some cases, ADHD in children or adolescents can even be a marker for an emerging bipolar disorder. The primary distinction between bipolar disorder and ADHD is the presence of a manic or hypomanic episode, which occurs in patients with bipolar disorder but not those with ADHD.

Schizophrenia. Severe manic episodes that include delusions and hallucinations may be easily confused with schizophrenia. (African-American men are more likely to be diagnosed with schizophrenia than with bipolar disorder.) The key factors that distinguish bipolar disorder from schizophrenia include:

The presence of one or more manic or hypomanic episodes in bipolar disorder, but not in schizophrenia
A flat emotional expression, with no variability in the voice among people with schizophrenia
People with bipolar disorder are typically very expressive

Substance Abuse. Up to 60% of patients with bipolar disorder abuse alcohol and drugs at some point during their illness. Both diagnosis and treatment are difficult in such cases, since substance abuse is often a method of self-treatment, and withdrawal can produce symptoms of mania or severe depression. The effects of cocaine in a heavy user can also produce abnormal mood swings that closely resemble those of bipolar disorder.

Other Causes of Mood Swings. Other conditions that can cause mood swings include:

Thyroid disorders
Adrenal disorders (Addison's disease or Cushing syndrome)
Vitamin B12 deficiency
Neurologic disorders such as Huntington's disease, epilepsy, brain tumors, encephalitis, or multiple sclerosis
Medications, including corticosteroids and certain drugs used to treat anxiety and Parkinson's disease

Patients should be tested for drugs or alcohol if the doctor suspects that they have been using these substances. Blood tests for thyroid function should also be performed.

Noninvasive imaging tests of the brain using magnetic resonance imaging (MRI) and positron-emission tomographic (PET) scans are being evaluated in clinical trials for detecting abnormalities in the brain. The results of these tests may eventually help identify bipolar disorder and test the effectiveness of various treatments. However, imaging tests do not currently play a role in diagnosing bipolar disorder.

The number of children diagnosed with bipolar disorder has increased dramatically during the past decade. Psychiatrists debate whether bipolar disorder was formerly under-diagnosed in children or whether it is being over-diagnosed now. Part of the controversy concerns the diagnostic criteria used for children and adolescents. Some bipolar symptoms, such as irritable mania, share characteristics with common childhood anger outbursts or behavioral disorders such as conduct disorder and attention deficit hyperactivity disorder. In addition, many children with bipolar disorder also have behavioral and developmental disorders. These overlapping conditions can complicate diagnosis.

The American Academy of Child and Adolescent Psychiatry (AACP) recommends that doctors use specific screening questions to diagnose bipolar disorder. These questions are designed to evaluate periods of mood changes associated with sleep disorders and restlessness. Doctors should also ask about family histories of mood disorders. The AACP cautions that the validity of diagnosing bipolar disorder in children younger than 6 years old has not been established.

Bipolar disorder is treated with powerful psychiatric drugs that can cause serious side effects. It is very important to make sure that a child’s symptoms are due to bipolar disorder, rather than emotional or behavioral issues, before prescribing these medications.

Treatment

Bipolar disorder is a recurrent disease that can be unpredictable. The major goals of treatment are to:

Treat and reduce the severity of acute episodes of mania or depression when they occur
Reduce the frequency of episodes
Avoid cycling from one phase to another
Help the patient function as best as possible between episodes

The doctor will first try to determine what may have triggered the attack and identify any accompanying medical or emotional problems that might interfere with or complicate treatment.

Some experts think that the best way to treat bipolar disorder is through a disease management model, similar to those used for treating diabetes and asthma. In this “collaborative care” model, patients are treated by a multi-disciplinary team of psychiatrists and nurses. The nurses provide patient education on medication side effects, early warning signs of symptoms, and coping skills. In several 2006 studies, patients who received this treatment model reported fewer symptoms, more productive time at work, better relationships with family members, and general improvement in quality of life.

The treatments for bipolar disorder, while very effective, pose some specific challenges for the patient:

Mood variations in bipolar disorder are not predictable, so it is sometimes difficult to tell if a patient is responding to treatment or naturally emerging from a bipolar phase.
A patient with bipolar disorder cannot always reliably inform the doctor about the state of the illness.
The patient is likely to need more than one medication during the course of the disease. This increases the risk for distressing side effects. Noncompliance is common.
Patients often have more than one medical problem and need different drugs to treat each condition. Such medications may interact with drugs used to treat bipolar disorder or increase side effects. For example, children with bipolar disorder have a higher risk for attention deficit-hyperactivity disorder, which is treated with stimulants that can complicate bipolar treatment.
Family members who have not been educated about the disorder may interfere with the treatment.
Treatment strategies for children and the elderly have not been intensively studied and have not been clearly defined.
Treatments may be costly.

The following are the treatment options for most patients with bipolar disorder, depending on the bipolar disorder phase or episode. Patients should understand that, even with aggressive therapy, either mania or depression recurs in almost three-quarters of patients.

Drugs Used in Bipolar Disorder. Mood stabilizing drugs are the mainstay for patients with bipolar disorder. They are defined as drugs that are effective for acute episodes of mania and depression and that can be used for maintenance. The standard first-line mood stabilizers are lithium and valproate. Both drugs stimulate the release of the neurotransmitter glutamate, although they appear to work through different mechanisms. Other drugs may also be used.

Lithium. Lithium has been used for years for bipolar disorder. It remains the best drug for people with pure mania characterized by euphoria and pure depression. Although imperfect, it is also an effective long-term drug for many patients with other bipolar subtypes.
Antiseizure Drugs. Valproate (valproic acid) carbamazepine (Tegretol, Carbatrol, Equetro), oxcarbazepine (Trileptal), and lamotrigine (Lamictal) are the most established antiseizure drugs. Other anti-seizure drugs used or investigated for bipolar include gabapentin (Neurontin), zonisamide (Zonegran) and topiramate (Topamax). To date, it is not clear if any of these newer drugs are useful for the treatment of acute mania.
Atypical Antipsychotics. Drugs known as atypical antipsychotics are used to treat schizophrenia and also have mood stabilizing properties that are applicable to bipolar disorder. They may be used either alone or in combination with lithium or valproate. Clozapine (Clozaril) was the first of these drugs, but it has not yet been approved for treatment of bipolar disorder. The newer atypical antipsychotics include olanzapine (Zyprexa), risperidone (Risperdal), quetiapine (Seroquel), ziprasidone (Geodon), and ariprazole (Abilify).

Such drugs may be used in combination with each other. Additional drugs, such as conventional antipsychotics, antidepressants, antianxiety drugs, or experimental drugs are used as necessary.

Electroconvulsive Therapy. Electroconvulsive therapy is a very effective treatment that may be administered in certain patients for acute episodes or for maintenance.

Non-Medical Treatments. In addition to medical treatments, psychotherapy and sleep management are also parts of bipolar disorder treatment. They can help reduce symptoms and prevent relapse.

The Systematic Treatment Enhancement Program for Bipolar Disorder (STEP-BD), an ongoing trial supported by the National Institute of Mental Health, is the largest treatment study ever conducted for bipolar disorder. With plans to enroll approximately 5,000 patients, STEP-BD aims to evaluate all the best-practice treatment options used for bipolar disorder, including mood-stabilizing medications, antidepressants, and atypical antipsychotics. It will also evaluate psychosocial interventions, including cognitive behavioral therapy, family-focused therapy, interpersonal and social rhythm therapy, and psychoeducation. Results of STEP-BD may clarify the best treatments for bipolar disorder.

Step 1. Determine the Need for Hospitalization and Eliminate Triggers. The first step in treating an acute manic episode is to rule out any life-threatening conditions and eliminate any triggers, such as antidepressants or other substances that can elevate moods.

Patients often require hospitalization at the onset of acute mania. The need for hospitalization depends on a number of factors:

Whether the patient is at risk for suicide or for harming others
The availability of social and emotional support at home

Step 2. Control Symptoms of Acute Manic with a Mood Stabilizer. Doctors often try different drugs to control a manic episode. If a current drug does not work well, another type of drug may be added or substituted. It may take several weeks for a mood stabilizer to take effect, and other drugs may be needed.

The following is an example of a stepped approach recommended by some experts:

Initiating a mood-stabilizing drug is the critical first step. Either valproate or lithium is the standard first drug for most manic episodes. Lithium is effective in 60 - 80% of all hypomanic and manic episodes. Carbamazepine is usually used in place of valproate to treat patients with multiple manic episodes, mixed episodes, and rapid cycling. Combinations of these mood stabilizers may be used if the patient does not respond to a single drug.
If the patient does not respond fully within a week, atypical antipsychotics may be added to one or more mood stabilizers. Atypicals include olanzapine (Zyprexa), risperidone (Risperdal), quetiapine (Seroquel), apriprazole (Abilify), and ziprasidone (Geodon). Clozapine (Clozaril), the oldest atypical drug, also works well but it is not generally used because of its potential for severe side effects and the need for weekly monitoring of white blood cell counts.

Step 3. Addition of Other Treatments. Other treatments may be added to speed recovery, treat any psychosis, and achieve remission. They include:

Older antipsychotic drugs (also called typical antipsychotics), such as haloperidol (Haldol), may be used for acute mania. They can cause severe side effects, however, particularly extrapyramidal effects, which disrupt motor control. They are not generally used on a long-term basis for treating bipolar disorder.
Benzodiazepines, such as clonazepam (Klonopin) or lorazepam (Ativan), are anti-anxiety drugs that may be particularly beneficial if the patient is experiencing severe mania.
Electroconvulsive therapy. This treatment helps patients who do not respond to medication and may even be life-saving in elderly patients with severe late-onset mania.

Step 4. Terminate Some Drug Treatments. Drugs may be stopped under the following circumstances:

When side effects are intolerable
When the patient does not respond to the maximum dose
When the patient improves and recovery is sustained

In cases of improvement and sustained recovery, the neuroleptic or benzodiazepine is slowly withdrawn and only the mood-stabilizing drug is continued.

Step 5. Continuation of Mood Stabilizers. Mood stabilizers are typically continued for about 8 weeks, unless the patient shows signs of shifting to another mood state. If the patient remains stable at that time, the doctor may decide to continue maintenance treatment or to gradually withdraw medications.

Depressive episodes pose a particular challenge. They are a significant cause of suffering, yet the use of standard antidepressants poses a significant risk for triggering mania. It is also not clear if standard antidepressants work for bipolar depression. In fact, depressive episodes are very difficult and patients who do not respond to mood stabilizers may endure prolonged depressive episodes up to 2 - 3 months.

Lithium or lamotrigine are the standard first-line treatments for depressive episodes. Many studies indicate that lithium works better for controlling manic states, and that lamotrigine works better for bipolar depression.

If improvement does not occur within 2 - 4 weeks, an antidepressant may be added. Antidepressants alone are not recommended. The first choices for antidepressants are bupropion (Wellbutrin) or paroxetine (Paxil). Alternatives include one of the selective serotonin reuptake inhibitors (SSRIs), such as fluoxetine (Prozac), a newer antidepressant such as venlafaxine (Effexor), or a monoamine oxidase inhibitor (MAOI).

Several studies have found no additional benefits from antidepressants. Many studies indicate that antidepressants may cause patients to “switch” to a manic state. Any patient with bipolar disorder who takes antidepressants and who develops symptoms of hypomania should stop taking these drugs, because hypomania is often a sign of impending mania. All antidepressants should be tapered after the mood has been stabilized for a month.

An atypical antipsychotic combined with a mood stabilizer is another treatment option. In 2003, the Food and Drug Administration (FDA) approved a drug (Symbyax) that combines the atypical antipsychotic olanzapine and the SSRI antidepressant fluoxetine. Symbyax was the first drug to be specifically approved for treatment of bipolar depression. In 2006, quetiapine (Seroquel), which is approved for treatment of bipolar mania, received an additional approval for treatment of bipolar depression.

Other Treatments. Cognitive-behavioral therapy or other psychotherapy programs may help patients endure depressive episodes by developing ways to manage negative thoughts and behaviors. Electroconvulsive therapy is another option for depression that does not respond to less intense approaches.

The first step in treating rapid cycling is to try to identify and resolve other factors, such as drug abuse or hypothyroidism, which may have caused this condition. Many patients may require a combination of medications to control rapid cycling:

Antidepressants, particularly SSRIs, may prompt rapid cycling and should be tapered off.
Lithium or valproate is a first-line treatment for rapid cycling.
Lamotrigine is an alternative treatment for rapid cycling.
Atypical antipsychotics (olanzapine, aripiprazole, ziprasidone, risperidone) are approved to treat mixed episodes. These drugs are used either alone or in combination with lithium or valproate.
One biological mechanism involved with rapid cycling is an excessive influx of calcium into brain cells. Cardiovascular drugs called calcium channel blockers may be beneficial for ultra-rapid cycling.
Low thyroid (hypothyroidism) is involved in some cases of rapid cycling. In these cases, levothyroxine, a synthetic derivative of the thyroid hormone T4 (thyroxine), has helped stabilize rapid-cycling patients.
Electroconvulsive therapy can be useful in emergency situations.

In addition, other measures should be taken:

Patients should avoid anti-anxiety drugs, alcohol, caffeine, and stimulants.
Patients should avoid exposure to bright light.
All efforts should be made to help the patient sleep normally.

Drugs Used During Maintenance. Relapse occurs in most patients after treatment of acute attacks, and patients who are at high risk for recurring episodes should consider life-long maintenance therapy. This usually involves mood-stabilizing drugs:

Lithium is a first-line mood stabilizer used in maintenance therapy. The anti-epileptic drug valproate is also a first-line treatment. In general, the two work equally well, although valproate may be better for patients who have had multiple manic episodes. There are some differences in side effects, but the drop-out rates between the drugs are similar. Lithium has proved effective for preventing relapses of manic episodes, but may not work as well for controlling depressive symptoms.
Lamotrigine, an anti-epileptic drug, was approved in 2003 for long-term maintenance treatment. It is also used as a first-line drug for treating depressive episodes.
Carbamazepine and oxcarbazepine are other anti-epileptic drugs used as alternative maintenance treatments.
Atypical antipsychotics may be used for maintenance, particularly in combination with a mood stabilizer. In 2004, olanzapine became the first atypical antipsychotic to be approved specifically for maintenance treatment.

The general recommendations for maintenance therapy with lithium are as follows:

The earlier lithium is started in the disease process, the better. Studies suggest that patients on long-term lithium therapy have survival rates comparable to the general population, but those who permanently drop out of therapy have significantly lower survival rates due to an increased suicide risk.
Lithium still works for patients who discontinue and then restart treatment later on. In such cases, however, there may be a greater need for drug combinations. In addition, patients who stop and start again may be at higher risk for hospitalization than those who use the drug continuously.
For those who want to stop, a gradual discontinuation (over 15 - 30 days) may help to delay recurrence. Stopping lithium quickly poses a high risk for relapse and even for suicide.

Information on clinical care of pregnant women with bipolar disorder remains very limited. In fact, in one survey, almost half of women with bipolar disorder were discouraged by their doctors from becoming pregnant. Nevertheless, after careful counseling about medications, possibilities for relapse, and disease severity, nearly two-thirds of them decided to attempt pregnancy.

Risks for Bipolar Episodes. Some studies suggest the following risks for bipolar episodes during and after pregnancy:

In women who discontinue lithium during pregnancy, the chance for recurrence of bipolar disorder is the same as in non-pregnant women, which is over 50%.
Pregnant women with bipolar disorder are at particularly high-risk for recurrence in the period after childbirth. In one study, symptoms recurred in 74% of women after delivery, and another 20% were hospitalized within 90 days after giving birth. The risk for depressive or mixed states is particularly high.

Drugs for Bipolar and Pregnancy. It is not ethical to test drugs during pregnancy, so all known effects of bipolar drugs are reported anecdotally. It is well-known, however, that most mood stabilizers used for bipolar disorder carry a high risk for the fetus, particularly if they are taken during the first trimester. Taking mood stabilizers at the time of delivery may help reduce the risk of manic episodes occurring after the baby is born. However, caution is still advised. Reported effects of drugs taken during pregnancy include:

Lithium can pass through the placenta and affect the fetus. When possible, patients should avoid taking lithium during pregnancy, especially during the first 3 months. Studies report that lithium use during the first trimester may cause heart defects and thyroid problems in the baby. If taken immediately before childbirth, lithium can also cause muscle weakness and drowsiness in newborn infants. Women who must take lithium during pregnancy should take the lowest possible dosage and stop the drug 1 - 2 days before delivery. Mothers who are taking lithium should not nurse their babies, since lithium is concentrated in breast milk.
The antiseizure drugs valproate and carbamazepine both greatly increase the risk for physical malformations, developmental delay, and spina bifida in babies. They appear to have minimal effect on breastfeeding, however. Lamotrigine can cause cleft lip and palate birth defects if taken during the first trimester.
Small studies have suggested that the atypical antipsychotic olanzapine does not increase the risk for birth defects. However, it does pose a great risk for excess weight gain that could be unhealthy during pregnancy. Less is known about the effects of other atypical antipsychotics during pregnancy.

Electroconvulsive Therapy (ECT). In spite of its bad press, ECT appears to be very beneficial for women with bipolar disorder who become pregnant. The patient should discuss this option with her doctor.

Doctors are still trying to decide the best treatment of bipolar disorder in children and adolescents. The drugs used for bipolar disorder have considerable side effects, which may be even more severe in younger people. Parents should consider the potential risks and benefits of treatment for their children.

Until recently, lithium was the only drug approved for treating bipolar disorder in children (age 12 years and older). In 2007, the FDA approved the atypical antipsychotic risperidone (Risperdal) for short-term treatment of manic or mixed episodes of bipolar I disorder in children ages 10 - 17.

Lithium is generally used as the first-line treatment, with valproate and risperidone (or other atypical antipsychotics) as alternatives. If treatment with a single drug does not work, a combination of drugs may be used.

Lithium and valproate are the drugs most studied in children and adolescents. However, side effects of these drugs in children may include severely impaired thinking, acne, increased urination, weight gain (lithium), and menstrual irregularities and polycystic ovary syndrome (valproate). Side effects of risperidone may include drowsiness, fatigue, increased appetite, nausea, dizziness, dry mouth, tremor, and rash.

Pediatric prescriptions for atypical antipsychotics have been increasing in recent years. However, the safety and effectiveness of these drugs for children and adolescents has not been established. They appear to work well in the short-term, but a 2006 study noted that there is little available evidence concerning their long-term effects.

Psychotherapy is also an important addition to drug treatment. Therapy that includes the entire family is important. Electroconvulsive therapy (ECT) may benefit adolescents with bipolar I disorder who suffer severe episodes of mania or depression and who have not been helped by medication.

Medications

Lithium (Carbolith, Duralith, Lithobid, Lithizine, Eskalith, Lithane) is one of the standard mood stabilizing drugs for bipolar disorder. Lithium is extremely helpful for most patients and it significantly reduces the rate of hospitalizations in bipolar disorder. Some studies report the following advantages of lithium:

Lithium is effective in 60 - 80% of all hypomanic and manic episodes. (Valproate may be better in patients with multiple manic episodes, mixed episodes, and rapid cycling.)
It helps to prevent relapses.
It helps psychosocial functioning.
It may help reduce the risk for suicide regardless of its effects on stabilizing mood.
It works well for most patients even if they have discontinued taking it and wish to restart treatment.

Administration of Lithium. Lithium may take weeks to become totally effective, so patients should not expect an immediate response during an acute episode. Doctors may take different approaches to administering the drug:

Some doctors initially administer lithium in two low doses and gradually increase the dosage over time until an effective (therapeutic) level is achieved.
Another approach is to administer a higher dose initially and measure blood levels of the drug after 24 hours. The doctor uses this information combined with a chart called a nomogram to calculate the doses most likely to be therapeutic.

In addition to drugs, several factors may affect lithium levels:

Seasonal change -- lithium levels may be higher in summer.
Menstrual cycle -- lithium levels may drop during the premenstrual phase.
Weight loss
Changes in salt intake
Dehydration
Diarrhea

Lithium levels should be monitored regularly. Side effects can occur at therapeutic levels or at those only slightly higher than desired. Blood tests that measure drug levels should be conducted frequently during acute attacks and about every 3 months during maintenance therapy.

Lithium Toxicity. Evidence of moderate toxicity include:

Trembling hands
Nausea
Increased urine output
Blurred vision
Some loss of coordination

Severe reactions occurring at higher blood levels, include:

Vomiting
Convulsions
Uncontrolled jerky movements in arms and legs
Stupor
Coma

Very high blood levels of lithium can be fatal. If overdose occurs, drugs should be stopped immediately and one or more of the following steps taken, depending on the severity:

Patients are given fluids and drugs to increase excretion of lithium salts.
Gastric lavage, a procedure that rinses the stomach, may be used to treat very recent overdoses.
Hemodialysis, a procedure that filters lithium out of the blood, may also be performed in severe cases.

Side Effects. Even for patients who do not experience a severe response, long-term use of lithium is not without problems. Weight gain is one of the main reasons why some patients want to stop taking the drug. Other side effects include:

An unpleasant taste in the mouth
Hair loss
Skin eruptions that can resemble acne and make psoriasis worse
Low thyroid function
An increased risk for diabetes
A blunted sexual drive
Dulled emotions and lack of mental clarity
Memory loss
Lack of motor coordination
Increased sensitivity to light

In some cases, light sensitivity may slightly affect a person's ability to recognize colors. More seriously, it can cause problems with night driving. This effect occurs regardless of how long a person has been on the drug. Experts recommend that patients wear sunglasses outside and avoid extensive exposure to bright light.

Drug Interactions. Because lithium is eliminated from the body by the kidneys, any drugs or dietary factors that slow the kidneys' actions may increase lithium blood levels and should be used with great caution. Such drugs include:

Nonsteroidal anti-inflammatory drugs (NSAIDs)
Thiazide diuretics
ACE inhibitors

There have been reports of interactions between lithium and certain drugs commonly used in combination, including:

Antipsychotics
Anticonvulsants
Calcium-channel blockers

The risks associated with these drug interactions are very low, but caution is needed.

Patients should be sure to contact their doctor if they have any suspicious symptoms or illnesses.

Noncompliance. Noncompliance is common. One study of lithium users found that patients took their medication only 34% of the time. Another reported that nearly a third of patients eventually went off the drug.

Side effects are certainly one reason for noncompliance. Some patients regret the loss of their manic episodes and the exhilaration and creativity that sometimes accompany them. In one small study of artists with bipolar disorder, however, only 25% felt their work had declined, while another 25% found no change in their creative output, and 50% believed that lithium had improved their output.

Despite side effects and other concerns, this important drug saves lives. Doctors are confident that lithium, which has been in use for more than 50 years, can be taken safely, even for life, by most patients.

Antiseizure drugs, also called anti-epileptics or anticonvulsants, affect the neurotransmitter gamma aminobutyric acid (GABA), which helps prevent nerve cells from over-firing. These drugs may be an alternative for patients (especially substance abusers) who do not tolerate or respond to lithium. They also may be used in combination with lithium, atypical antipsychotics, or other drugs.

Standard Antiseizure Drugs.

Valproate (Depakote), also called valproic acid or divalproex, is now a first option for many bipolar disorder patients. It works well for many patients with mania, rapid-cycling, and mixed states, as well as for patients who are substance abusers. Valproate also helps migraine headaches, a common problem among patients.
Lamotrigine (Lamictal) is approved for maintenance treatment of adults with bipolar I disorder. It appears to be particularly helpful for patients with rapid cycling and bipolar II disorder, in whom depression remains problematic after taking other mood stabilizers.
Carbamazepine (Epitol, Tegretol), a standard alternative antiseizure drug used for mood stabilizing, is usually the second anti-seizure medication of choice. In 2004, the FDA approved an extended release form of carbamazepine (Equetro). Another drug, oxcarbazepine (Trileptal), is similar to carbamazepine.
Other anti-seizure drugs used or investigated for bipolar include gabapentin (Neurontin), zonisamide (Zonegran) and topiramate (Topamax). To date, it is not clear if any of these newer drugs are useful for the treatment of acute mania.

General Side Effects. The side effects given here are associated with valproate. Other antiseizure drugs have similar effects and some specific ones of their own. Most are usually minor, occurring early in therapy and then subsiding. Valproate side effects include:

Gastrointestinal problems such as nausea, vomiting, and heartburn
Headaches
Visual disturbances
Ringing in the ear
Hair loss
Weight gain (a significant problem with valproate)
Agitation
Odd movements
Menstrual irregularities and a higher risk for polycystic ovary syndrome (PCOS)
Birth defects when taken by pregnant women
Cognitive impairment and symptoms of Parkinson's disease

Very serious side effects are possible. Stevens-Johnson syndrome (SJS) is a rare but severe and potentially life-threatening, rash that can develop as a side effect of carbamazepine, lamotrigine, oxcarbazepine and other anticonvulsants. Because this is a very serious condition, these drugs are discontinued at the first sign of rash. The risk of serious skin reactions is 10 times higher for patients of Asian ancestry than Caucasians. The FDA recommends that people of Asian ancestry get a genetic test before starting carbamazepine to determine if they are at risk for this side effect.

Other serious side effects, also rare, may include liver damage, convulsions, coma, and pancreatitis.

Atypical antipsychotics are standard drugs for schizophrenia. They are now proving to be beneficial for bipolar disorder when used alone or in combination with the mood stabilizers that treat mania. These drugs include clozapine (Clozaril) (the first atypical antipsychotic), olanzapine (Zyprexa), risperidone (Risperdal), paliperidone (Invega), quetiapine (Seroquel), aripiprazole (Abilify), and ziprasidone (Geodon).

Olanzapine was the first atypical antipsychotic approved for treatment of bipolar disorder. In 2000, the FDA approved it to treat bipolar mania and mixed states. In 2004, the drug became the first atypical antipsychotic approved for bipolar maintenance treatment.
Symbyax, a drug that combines olanzapine and the antidepressant fluoxetine, was approved in 2003 for treatment of bipolar depression.
Risperidone, ziprasidone, and ariprazole are approved for treatment of bipolar mania and mixed states. Paliperidone (Invega), which is chemically related to risperidone, was approved in 2007 for treatment of schizophrenia but has not yet been approved for bipolar disorder.
Quetiapine is approved for treatment of bipolar mania and bipolar depression, making it the only drug approved for treating both manic and depressive states.
Clozapine has not been approved for treatment of bipolar disorder, but has shown promise in investigational studies. However, this drug has more significant side effects than other atypical antipsychotics. It poses a risk of white blood cell reduction (agranulocytosis).

Side Effects. Although atypical antipsychotics have fewer severe side effects than standard antipsychotics, many patients fail to comply with regimens containing them. Common side effects include:

Nasal congestion or runny nose
Drooling
Dizziness
Headache
Drowsiness -- however, these drugs may also cause restlessness and insomnia.
Constipation
Rapid heart beat
Difficulty urinating
Skin rash
Increased body temperature
Confusion, short-term memory problems, disorientation, and impaired attention
Weight gain -- risk is highest with clozapine and olanzapine, lowest with aripiprazole and ziprasidone

More serious risks include:

Diabetes (See Diabetes Risk and Atypical Antipsychotics)
Weight gain and metabolic problems. The risk is highest for olanzapine, and lowest for aripiprazole and ziprasidone.
Unhealthy cholesterol levels. Particularly with olanzapine, increased risk for high levels of trigylcerides and total cholesterol.
Seizures
Heat stroke
Sudden drop in blood pressure (hypotension)
A significant drop in white blood cell count (neutropenia) and neutrophils (agranulocytosis) occurs in 1% or more of patients, generally in the first 6 months after starting treatment. Patients should have their white blood count and absolute neutrophil count regularly monitored if they take clozapine.
Extrapyramidal side effects, which are lack of motor coordination and involuntary movements
Cataracts and worsening of any existing glaucoma
Increased prolactin levels -- prolactin is a hormone associated with infertility and impotence. High levels can cause menstrual abnormalities and may increase the risk for osteoporosis and possibly breast cancer.

Diabetes Risk and Atypical Antipsychotics. In 2003, the FDA requested that the strongest warning be added to the product labels of all atypical antipsychotics. This so-called black box warning advises that these drugs can increase the risk of high blood sugar (hyperglycemia) and diabetes. (Olanzapine is more likely to cause high blood sugar levels than other atypical antipsychotic medicines.) The FDA recommends that:

Patients with an established diagnosis of diabetes who begin atypical antipsychotic treatment should be regularly monitored for worsening of blood sugar control.
Patients with risk factors for diabetes (obesity, family history of diabetes) should undergo fasting blood sugar testing at the beginning of atypical antipsychotic treatment and periodically during treatment.
All patients treated with atypical antipsychotics should be monitored for high blood sugar (hyperglycemia) symptoms.
Patients who develop hyperglycemia symptoms should undergo fasting blood sugar testing.

Antidepressants are sometimes used for depressive episodes in bipolar disorder, but their use is controversial. They may trigger mania in 12 - 28% of patients. In addition, a number of studies report no additional benefits from antidepressants. Specific antidepressants may be beneficial in certain circumstances. However, any patient on antidepressants who develops symptoms of hypomania should stop taking these drugs, since hypomania is often a sign of impending mania. All antidepressants should be tapered off after the mood has been stabilized for a month.

Bupropion. The antidepressant bupropion (Wellbutrin) appears to pose a lower risk for triggering mania than do other antidepressants. Side effects include restlessness, agitation, sleeplessness, headache, rashes, stomach problems, and in rare cases, hallucinations and bizarre thinking. Initial weight loss occurs in about 25% of patients. High doses may cause seizures. This side effect is uncommon and tends to occur in patients with eating disorders (anorexia or bulimia) or those with risk factors for seizures.

Selective Serotonin Reuptake Inhibitors. Serotonin reuptake inhibitors (SSRIs), such as fluoxetine (Prozac), citalopram (Celexa), sertraline (Zoloft), and paroxetine (Paxil), are sometimes used to treat bipolar depression, but their benefits have not yet been established. They may be useful in patients whose depression does not respond to lithium. They do not appear to be useful as an add-on treatment to lithium. Another antidepressant, venlafaxine (Effexor), may also be used in patients with severe cases of depression who do not respond to other treatments.

Side effects of SSRIs include:

Nausea and gastrointestinal problems, which usually wear off over time
Agitation, insomnia, mild tremor, and impulsivity
Dry mouth, which can increase the risk for cavities and mouth sores
Headache
Sexual dysfunction

Some weight loss may occur during the first few weeks of treatment, but over time patients on maintenance treatment typically return to their pretreatment weight.

Monoamine Oxidase Inhibitors (MAOIs). Older drugs known as monoamine oxidase inhibitors (MAOIs), particularly tranylcypromine (Parnate) are recommended for depression that does not respond to newer antidepressants. MAOIs can interact with certain foods and cause severe high blood pressure. Such foods have high tyramine content and include aged cheeses, most red wines, vermouth, dried meats and fish, canned figs, fava beans, and concentrated yeast products. MAOIs can also have severe interactions with certain drugs, including some common over-the-counter cough medications. In such cases, severe high blood pressure or dangerous reactions can occur. It is important that patients discuss with their doctor any other medications they are taking.

Other Treatments

Electroconvulsive therapy (ECT) is a non-drug treatment for bipolar disease and other mental disorders, such as severe depression. It is commonly called shock therapy. ECT has received bad press since it was introduced in the 1930s. But, over the years it has been refined, and is now considered a very safe treatment.

Research suggests ECT may be particularly beneficial for:

Patients who need immediate stabilization of their condition and who cannot wait for medications to work
Most patients with mania -- especially elderly patients with severe mania
Patients who suffer suicidal thoughts and guilt during the depressive phase
Pregnant patients
Patients who cannot tolerate drug treatments
Patients with certain types of heart problems
Young patients

In a review of studies, about 80% of ECT-treated patients experienced improvement, and for some, it is the only treatment that works.

The Procedure. ECT is performed on an outpatient basis and does not require hospitalization. In general, the ECT procedure is performed as follows:

A muscle relaxant and short-acting anesthetic are given to the patient.
A small amount of electricity is sent to the brain, causing a generalized seizure that lasts for about 40 seconds.
The response to ECT is usually very fast, and the patient often needs less medication afterward.

Side Effects. Side effects of ECT may include temporary confusion, memory lapses, headache, nausea, muscle soreness, and heart disturbances. Taking the drug naloxone immediately before ECT may help reduce its effects on concentration and some (but not all) forms of memory impairment. Concerns about permanent memory loss appear to be unfounded.

Biologic Effects of ECT on Bipolar Disorder. The precise way that ECT benefits patients with bipolar disorder is not clear. ECT may help by:

Causing changes in the brain's physiology. For example, ECT may increase the permeability of the blood-brain barrier, produce an antiseizure effect (similar to the effects of antiseizure drugs used as mood stabilizers), and reduce blood flow in parts of the brain associated with improved mood.
Causing various hormonal changes, particularly with thyroid-related hormones.
Balancing dopamine levels. This brain chemical plays an important role in bipolar disorder as well as other conditions for which ECT is sometimes recommended, including delusional depression.
Stimulating growth of neurons in the hippocampus (the area in the brain responsible for memory).

Some studies are finding that maintenance electroconvulsive therapy (ECT) may be helpful for patients who do not respond to medications. In one study of patients with bipolar disorder, those who had intractable recurrent episodes received monthly ECT treatments for more than a year and a half. Without ECT, those patients spent an average of almost half a year in the hospital, suffering at least three episodes annually. After ECT, all the rapid cyclers achieved full or partial remission.

Transcranial Magnetic Stimulation. Repeated transcranial magnetic stimulation (rTMS) is also being studied for unipolar and bipolar depression. Unlike ECT, this procedure does not appear to cause seizures, memory lapses, or impaired thinking. The only common side effect is a mild headache.

Therapy and Lifestyle Changes

Psychotherapy is an important addition to medication. Many approaches are proving to be very useful. Trained mental health professionals can:

Educate patients about bipolar disorder and its treatments
Teach patients to recognize and manage early warning symptoms of imminent manic or depressive episodes
Help them comply with drug regimens
Monitor the patient's on-going status
Intervene early in manic and depressive episodes to reduce the severity of the attack

In addition, psychotherapy can help patients:

Adjust to the reality of the illness and understand the negative consequences of mania -- particularly important for patients who consider their mania to be positive, creative, and exhilarating
Cope with feelings of guilt and remorse that occur after manic episodes
Deal with feelings of imperfection and despair

Therapists trained in cognitive-behavioral therapy (CBT) may be particularly helpful for many patients. CBT is a structured, conscious method that aims to help a patient recognize negative thoughts and behavioral patterns and to change them. CBT is known to be helpful for other mood disorders, including depression and anxiety, and some studies suggest that it benefits bipolar disorder patients as well. For example, in one recent study, patients who were given mood stabilizers and underwent a CBT program that was specifically designed to prevent relapse experienced fewer and shorter episodes and improved social functioning compared to those on mood stabilizers alone.

Using Cognitive-Behavioral Therapy for Bipolar Disorder. Typical goals of CBT for bipolar disorder patients include learning how to:

Recognize manic episodes before they become full-blown and change behaviors during an episode
Cope with depression by developing behaviors and thoughts that may help offset the negative mood

It is very important that partners, family members, or both be involved in therapy. CBT can help them learn how to accept the condition, the need for medications, and how to protect themselves and the patient financially during manic episodes. In fact, one study indicated that when a spouse of a patient learned ways of coping with the illness, the partner's chances of sticking to a prescribed treatment improved.

Supporting the Patient. Recommendations for supporting the patient include:

Create a treatment contract as a first step. In this contract, the patient and family agree to specific steps for maintaining emotional stability. If such measures fail, all parties agree on further actions to be taken during an acute episode, including requests for hospitalization.
Be supportive. Unlike relatives of patients with alcoholism who may be encouraged to get tough, relatives of patients with bipolar disorder must be strongly supportive because of the high risk for suicide with this disorder. Simply listening attentively and being empathic can help.
Get the patient to comply with treatment, even if it means threatening a hospitalization if the patient fails to comply.
Have ready a hotline number or the telephone number of a psychiatrist authorized to commit the patient. The doctor should be willing to facilitate commitment if a patient becomes violent or the family is on the verge of collapse.
Don't feel guilty and don't make the patient feel guilty. Bipolar disorder results from an imbalance of chemicals in the brain and not from anyone's fault.

Support for the Family. Unfortunately, actions that support a bipolar disorder patient may not be intuitive, and they take their toll. Loved ones must also care for themselves or they may also follow a path to severe depression. They should to boost energy and reduce stress through:

Exercise
Meditation
Relaxation techniques
Holidays away from the patient
Involvement in hobbies
Involvement in support groups, Internet resources with chat rooms, and message boards for bipolar disorder caregivers

Interpersonal problems (such as family disputes) and disruptions in daily routines or social rhythms (such as loss of sleep or changes in meal times) may make people with bipolar disorder more susceptible to new episodes of their illness. A form of psychosocial treatment called interpersonal and social rhythm therapy (IPSRT) focuses on maintaining a regular schedule of daily activities to reduce these potential triggers and improve emotional stability. Patients also learn how to avoid problems with personal relationships. Preliminary evidence suggests that IPSRT combined with drug therapy works better than medication alone. A 2-year study of patients with bipolar 1 disorder indicated that IPSRT may help prevent new manic episodes.

Exercise. Exercise is an important part of treatment, particularly in helping manage weight gain. It also helps increase feelings of well-being.

Sleep Management. Good sleep hygiene is particularly important for patients. One study reported that techniques used to enforce healthy sleep helped reduce mood cycling.

Diet. A healthy diet low in saturated foods and rich in whole grains, fresh fruits, and vegetables is important for anyone. People with bipolar disorder should be sure to maintain a regular healthy diet. They may need to restrict calories if they are on medications that increase weight.

Some research indicates that consumption of omega-3 polyunsaturated fatty acids found in oily fish (such as mackerel, sardines, salmon, and bluefish) may help reduce the symptoms of a variety of mental illnesses, including bipolar disorder. Researchers are investigating the effects of eicosapentaneoic acid (EPA) and docosahexaenoic acid (DHA) supplements for patients who have not responded to other treatments.

Guyliner, Manscara...The Boys Are Back in Town

BellaSugarUK — Wed, 30 Jul 2008 07:00:00 -0700

Boys in bands and indie men have been stealing our black eyeliners and smudgy kohl pencils for a while now – whether they're heading to a festival or just hanging out in Camden. The voice of middle England, aka The Telegraph, may be expressing subdued shock at the new 'guy-liner, man-scara' trend, but edgy London boys have been rocking the makeup look for the past few seasons.

British bad boy, Russell Brand is often photographed in eye makeup, although he covered up in dark glasses, for a night out at Boujis, last night. While Pete Doherty, The Killers' singer Brandon Flowers, The Horrors, and The Libertines, all regularly rock out in dark eyeliner and sometimes chipped black nail polish.

Today, everyone's talking about the launch of Guyliner, (£6.50), Just read more

Guyliner is a black kohl pencil specifically designed for men, to make their eyes look bigger, or for a grunge-inspired rock look. Now I'm not sure why men need a specific eye liner all of their own, but I'm tempted to buy it for Mr Bella, just because of the name. The cosmetics brand, Taxi are also bringing out a concealer and lip balm, for men, later in the summer – all stocked at Superdrug.

Peter Kelly, the creator of Taxi's range for men, told The Telegraph, "We've developed essentials any guy would borrow from his other half. It's about subtle make-up rather than wanting to create the drag queen look."

Thing is, most of the cool, indie boys I know love to wear drag now. Plus, surely the whole point of a man wearing makeup (as oppose to just using good skincare), is to push the boundaries of what is and what isn't acceptable. Surely as soon as eyeliner...sorry...Guyliner, becomes the norm, then the boys in bands will have to find something else to draw attention to themselves.

Maybe Sophie Ellis-Bextor style rainbow false eyelashes, or catwalk-cool glitter on the eyelids, perhaps?

HEALTH GUIDE REFERENCE FROM A.D.A.M

People who intentionally starve themselves into an emaciated state yet remain convinced that they are overweight are suffering from a condition known as anorexia nervosa. Anorexia is a severe emotional disorder that is increasingly common, especially among young women in industrialized countries where cultural expectations encourage women to be thin. Fueled by popular fixations with thin and lean bodies, anorexia is also affecting a growing number of men, particularly athletes and those in the military. People with anorexia are terrified of becoming obese and refuse to maintain a normal weight, putting themselves in danger of starvation.

Anorexia rarely begins in people who are older than 40 years of age. It most commonly appears in the teenage years, affecting up to 3 in 100 adolescents. Although anorexia seldom emerges before puberty, associated mental conditions, such as depression and obsessive-compulsive behavior, are usually more severe when it does. The onset of anorexia is often preceded by a traumatic or stressful event and it is usually accompanied by other emotional difficulties. Anorexia is a life-threatening condition that can result in death from starvation, heart failure, electrolyte imbalance, or suicide.

There are two main types of anorexia nervosa:

Restricting Type -- characterized by dieting, fasting, or excessive exercise
Binge-Eating/Purging Type (anorexic-bulimic) -- characterized by self-induced vomiting or misuse of laxatives, enemas, or diuretics. Binge eating may or may not occur, and purging (vomiting) is common even after small amounts of food have been eaten. This type carries greater medical risk.

Signs and Symptoms

The primary sign of anorexia nervosa is severe weight loss, accompanied by any number of physical and psychological symptoms and unusual behaviors related to food, eating, or exercise. A person for whom a healthy weight would be 125 pounds, for example, may drop 20, or even as much as 60, pounds below this. At the same time, the person may insist that they are overweight.

Physical Signs

Scanty or absent menstrual periods
Thinning hair
Dry skin
Cold or swollen hands and feet
Bloated or upset stomach

Psychological Signs

Distorted perception of self (that is, a great difference between how an individual believes they look and their actual physical appearance)
Inability to remember things
Poor judgment
Refusal to acknowledge the gravity of the illness
Obsessive-compulsive behavior (excessive need to control personal environment)
Depression (feelings of ineffectiveness, loss of interest in friends and former activities, lack of spontaneity, rigid thinking, lack of initiative, flattened emotional response, irritability, insomnia, and diminished interest in sex)

Behavioral Symptoms

Unusual behaviors related to food or eating (for example, hoarding or concealing food, refusing to eat in public, eating only one type of food, ritually cutting food into tiny pieces, intense study of diets and calories, planning and preparing elaborate meals for others)
Compulsive exercising
Preoccupation with body size or body image
Preoccupation with weight control, dieting

Causes

There is no specific cause of anorexia. Medical experts agree that several factors work together in a complex fashion to lead to the eating disorder. These may include:

Severe trauma or emotional stress (such as the death of a loved one or sexual abuse) during puberty or prepuberty.
Abnormalities in brain chemistry. Changes in serotonin levels, a brain chemical that regulates appetite, may contribute to other symptoms of anorexia nervosa such as depression, impulsiveness, obsessive behaviors, or other mood disorders. In addition, the process of purging may deplete tryptophan, an amino acid necessary for the production of serotonin, leading to further imbalances.
A cultural environment that puts a high value on thin or lean bodies.
Overbearing, controlling, and critical parents who do not show emotional warmth.
A tendency toward perfectionism, fear of being ridiculed or humiliated, a desire to always be perceived as being "good." A belief that being perfect is necessary in order to be loved. Because perfection is impossible, the inability to attain perfection reinforces the person's sense of being unworthy of being loved. Not eating, according to some experts, is a passive act of revenge directed toward those who will never love the person because of his or her lack of perfection.
Family history of anorexia. About one-fifth of those with anorexia have a relative with an eating disorder. In fact, it is common to discover that someone with anorexia has a mother or sister with this eating disorder as well. If one identical twin has anorexia, the other has more than a 50% chance of also developing it. It is not clear, however, to what extent this family connection is due to heredity or to learned behavior.
Infection. Some researchers report an association between beta-hemolytic streptococcal infection, or Epstein Barr virus (the virus that causes mononucleosis), and development of anorexia.

Risk Factors

Age and gender -- anorexia is most common in teens and young adult women.
Early onset of puberty
Living in an industrialized country
Depression -- although depression is associated with the development of anorexia, it does not cause the disorder. Depression in a family member also appears to increase the likelihood of developing an eating disorder.
Obsessive-compulsive disorder (OCD) or other anxiety disorders -- OCD is present in up to two-thirds of people with anorexia. OCD associated with an eating disorder is often accompanied by a compulsive ritual around food (such as cutting it into tiny pieces). Phobia, another type of anxiety disorder that may also be present in someone with an eating disorder, and OCD tend to emerge before the eating disorder, while panic attacks may develop after the diagnosis is made.
Avoidant or narcissistic personality disorders -- approximately one-third of those with the restricting type of anorexia have avoidant personalities, which is characterized by feelings of inadequacy, social inhibition, extreme sensitivity to negative comments or criticism, and avoidance of interpersonal relationships, both at work and on an intimate level. Borderline personality disorder (exceptionally unstable interpersonal relationships, extremely poor self-image, and excessively impulsive behaviors) may be a risk factor as well, but such individuals are more likely to develop bulimia.
Participation in sports and professions that put emphasis on a lean body (such as dance, gymnastics, running, figure skating, horse racing, modeling, wrestling, acting)
Difficulty dealing with stress (pessimism, tendency to worry, refusal to confront difficult or negative issues)
History of sexual abuse or other traumatic event
Dieting

Diagnosis

While your doctor will rely on points discussed in Signs and Symptoms -- such as excessive weight loss, refusal to maintain normal body weight, and distorted self-perception -- the doctor will also ask a series of questions to better determine whether or not anorexia is present. The SCOFF questionnaire, developed in Great Britain, is proving to be a very reliable method for diagnosing anorexia. A "yes" response to at least two of the following questions is a strong indicator of an eating disorder:

S: "Do you feel sick because you feel full?"
C: "Do you lose control over how much you eat?"
O:"Have you lost more than 13 pounds recently?"
F: "Do you believe that you are fat when others say that you are thin?"
F: "Does food and thoughts of food dominate your life?"

If an eating disorder is suspected, the doctor will order several laboratory tests. These serve to determine blood count (to assess for signs of anemia that may be related to lack of iron or vitamin B12), levels of electrolytes (minerals such as potassium, calcium, and magnesium), amylase (serum amylase is elevated when there is frequent vomiting), and protein, and kidney, liver, and thyroid functions. Your doctor may also order an electrocardiogram (which gives a graphic record of the electrical activity of the heart). This may be abnormal if there is a deficiency in an electrolyte or nutrient such as potassium or calcium. If a diagnosis of anorexia is made, the doctor will require frequent office visits to monitor the condition. It is best for a person with anorexia to work with a multidisciplinary team including a doctor, a psychologist or psychiatrist, and a registered dietitian.

Preventive Care

The most effective prevention strategy is the development, from an early age, of healthy eating habits and a strong body image. Cultural values that place a premium on lean or thin bodies need to be questioned. Education about the life-threatening nature of anorexia is also an important part of prevention.

In those who have already been diagnosed and treated for anorexia, avoiding recurrence of the eating disorder is the primary goal.

Family and friends should be urged not to focus on the patient's condition or on issues of food or weight. Mealtimes, for example, should be reserved for social interaction and relaxation, without any discussion of the disease.
Careful and frequent monitoring of weight and other physical signs by the health care provider can reveal signs of a relapse.
Cognitive or other forms of psychotherapy can help the person to develop coping skills and change the unhealthy thought processes that underlie anorexia nervosa.
Family therapy is helpful in addressing underlying contributing factors in the home environment and in enlisting the support and understanding of family members.

Treatment

Anorexia demands a multi-pronged treatment plan that addresses both the physical and psychological aspects of this disorder. Cognitive-behavioral therapy, often in combination with antidepressants, is a very effective therapeutic approach for treatment of eating disorders. Complementary and alternative methods of treatment (such as the use of herbs and mind-body medicine) are valuable adjuncts to usual ways of stimulating appetite, addressing nutritional problems, and helping the patient to develop a healthier body image and to learn to deal more productively with stress.

In general, the most important aspect of treating anorexia is restoring weight and preventing starvation. Hospitalization may be necessary, particularly under the following circumstances:

Continuing weight loss, in spite of outpatient treatment
Body mass index (BMI) -- BMI is a measurement that takes into account a person's height and weight) 30% below normal. The normal range is a BMI of 19 - 24.
Irregular heart rhythm
Severe depression
Suicidal tendencies
Low potassium levels
Low blood pressure

Generally, adequate weight gain (1 - 2 pounds per week) and appropriate changes in behavior require a 10 - 12 week hospital stay. To avoid bloating, abdominal upset, and fluid retention, those who are severely malnourished are started on a diet of 1,500 calories a day, gradually increasing to as much as 3,500 calories. Because anorexia triggers changes in metabolism, high caloric intake may be necessary to stimulate weight gain.

Unfortunately, there is no completely effective treatment for anorexia nervosa, and recovery can take many years. Even after some weight gain, many people with anorexia remain quite thin and risk of relapse is very high. Several social influences may make recovery difficult:

Friends or family who express admiration or envy of the patient's thinness
Dance instructors or athletic coaches who put a premium on having a very lean body
Denial on the part of parents or other family members
A patient's persistent belief that emaciation is not only normal but also attractive and that purging is the only way to avoid becoming overweight

Involving friends, family members, and others in the treatment of the individual, with education for everyone regarding the gravity of the disease, may diminish these influences.

Lifestyle

Treating anorexia nervosa involves major lifestyle changes. The person must not only alter eating habits but also adjust their self perception to no longer hold a distorted body image. The following lifestyle changes may help in this process:

Establishing regular eating habits and a healthy diet
Developing a support system and participating in a support group for help with stress and emotional issues
Cutting back on exercise if obsessive exercise has been part of the disease. Once sufficient weight gain has been established, controlled exercise regimens can be a positive reinforcement for appropriate eating habits and a way to reduce gastrointestinal distress.

Medications

Anorexia nervosa in some ways resembles other major psychiatric disorders, such as depression and obsessive-compulsive disorder, because people with anorexia exhibit some of the symptoms of these disorders (for example obsessive behavior, lack of enjoyment from life, and severely distorted perception of reality, in this case, of the body). This has led to the use of antidepressants for anorexia, particularly selective serotonin reuptake inhibitors (SSRIs), because these drugs are first-line treatments for OCD and depression. Medications, however, may not work alone and should be used in conjunction with a multidisciplinary approach that includes nutritional interventions and psychotherapy.

Serotonin Reuptake Inhibitors

Fluoxetine

Studies suggest that fluoxetine may increase weight and improve mood over several months in people with anorexia nervosa and depression. Similarly positive results were obtained in a preliminary study of anorexics whose body weight had already been partly restored.

Tricyclic Antidepressants

This class of antidepressants, including imipramine and desipramine, tend to be more effective for bulimia than anorexia.

Clomipramine

One study suggests that clomipramine has the potential to stimulate weight gain and improve symptoms of anorexia.

Antihistamines

Cyproheptadine

In one study, using high doses of cyproheptadine hydrochloride, which is thought to stimulate appetite, decreased the number of days necessary to achieve appropriate weight gain and relieved depression in those with restricting type anorexia.

Hormones

Estrogen together with progesterone may help restore normal menstrual cycles. This, however, does not generally have any effect on weight.

Nutrition and Dietary Supplements

Anorexics with low body weight, low BMI, and low serum albumin (the main protein in blood) levels are at increased risk for vitamin and mineral deficiency. Vitamin abnormalities may contribute to cognitive difficulties such as poor judgment or memory loss and other psychiatric conditions. These deficiencies can often be corrected with dietary interventions.

There are natural therapies, including dietary supplements, that may help the general health and well-being of a person struggling with anorexia to become more balanced. Always tell your health care provider about the herbs and supplements you are using or considering using, as some supplements may interfere with conventional treatments.

Following these nutritional tips may help reduce symptoms:

Avoid coffee and other stimulants, alcohol, and tobacco.
Drink 6 - 8 glasses of filtered water daily. However, do not fill up on water only.
Quality protein sources, such as organic meat and eggs, whey, and vegetable protein shakes, should be used as part of balanced program aimed at gaining muscle mass and preventing wasting. Talk with your health care provider about the best way for you to put on weight.
Try to avoid refined sugars, such as candy and soft drinks.

You may address nutritional deficiencies with the following supplements:

A multivitamin daily, containing the antioxidant vitamins A, C, E, the B-vitamins and trace minerals, such as magnesium, calcium, zinc, and selenium.
Omega-3 fatty acids, such as fish oil, 1 - 2 capsules or 1 tablespoonful oil two to three times daily, to help decrease inflammation and improve immunity. Essential fatty acids play a critical role in brain function and hormone regulation, key health issues in the anorexic individual.
Vitamin C, 500 - 1,000 mg one to three times daily, as an antioxidant and for immune support.
Coenzyme Q10, 100 - 200 mg at bedtime, for antioxidant, immune, and muscular support.
5-hydroxytryptophan (5-HTP), 50 mg two to three times daily, for mood stabilization.
Creatine, 5 - 7 grams daily, when needed for muscle weakness and wasting.
Probiotic supplement (containing Lactobacillus acidophilus), 5 - 10 billion CFUs (colony forming units) a day, for maintenance of gastrointestinal and immune health. You should refrigerate your probiotic supplements for best results.
L-glutamine, 500 - 1,000 mg three times daily, for support of gastrointestinal health and immunity.
Dihydroepiandosterone (DHEA), start at 5 mg three times a day and work up to 100 mg per day for 7 - 12 months for hormonal effects. It is recommended to use DHEA under the supervision of a qualified health care professional. If adverse effects develop, discontinue use.
Melatonin, 2 - 5 mg one hour before bedtime, for sleep and immune protection.

Herbs

Herbs are generally a safe way to strengthen and tone the body's systems. As with any therapy, you should work with your health care provider to get your problem diagnosed before starting any treatment. You may use herbs as dried extracts (capsules, powders, teas), glycerites (glycerine extracts), or tinctures (alcohol extracts). Unless otherwise indicated, you should make teas with 1 tsp. herb per cup of hot water. Steep covered 5 - 10 minutes for leaf or flowers, and 10 - 20 minutes for roots. Drink 2 - 4 cups per day. You may use tinctures alone or in combination as noted.

Ashwagandha (Withania somniferum) standardized extract, 450 mg one to two times daily, for general health benefits and stress.
Fenugreek (Trigonella foenum-graecum), 250 - 500 mg two to three times daily, for appetite stimulation.
Cayenne pepper (Capsicum annuum) standardized extract, 400 mg three times daily, for digestive stimulation.
Milk thistle (Silybum marianum) seed standardized extract, 80 - 160 mg two to three times daily, for detoxification support.
Fermented wheat germ extract, 1 packet dissolved in favorite beverage once daily, for immune effects and muscle gain.

Massage and Physical Therapy

Massage appears to be a helpful component of treatment for anorexia nervosa. Individuals using massage report lower anxiety levels and improved body image.

Homeopathy

A professional homeopath can provide supportive care to address various aspects of anorexia. Discuss homeopathy and anorexia with your health care provider.

Mind-Body Medicine

Cognitive Behavioral Therapy

Cognitive behavioral therapy is reported to be one of the most effective therapies for anorexia. It is based on the assumption that anorexia develops in response to life stresses. Treatment is aimed at confronting the individual's fears and avoidance behaviors and cultivating new problem-solving skills. It also aims to increase awareness of negative thought processes and to change them. Cognitive techniques are used to encourage patients to evaluate and challenge their automatic thoughts, examine their underlying assumptions, and replace them with realistic beliefs and actions based on reasonable self-expectations.

Family Therapy

Family therapy is recommended for both children and adults, in addition to individual therapy for the person with anorexia. Parents and other family members often have intense feelings of guilt and anxiety that they need to address. Family therapy is aimed, in part, at helping the parents or partner (in the case of an adult) understand the medical gravity of this illness and the ways in which they may be inadvertently contributing to it.

Hypnosis

Hypnosis has been reported to be successful as part of an integrated treatment program for anorexia nervosa. Hypnosis reportedly strengthens both self-confidence and the ability to cope, which may result in healthier eating, improved body image, and greater self-esteem.

Biofeedback

Studies suggest that biofeedback may be helpful in reducing stress in people with anorexia.

Other Considerations

Pregnancy

Anorexia poses several potential problems for women who are pregnant or wishe to become pregnant:

Difficulty getting pregnant and carrying a pregnancy to term because of higher rates of infertility and spontaneous abortion
Increased risk of low birth weight babies and birth defects
Malnourishment (particularly calcium deficiency) as the fetus grows
Increased risk of medical complications
Increased risk of relapse being triggered from the stress of pregnancy or parenthood

Prognosis and Complications

Medical complications associated with anorexia include:

Irregular heartbeat and heart attack
Anemia, often related to lack of vitamin B12
Low potassium, calcium, magnesium, and phosphate levels (particularly with binge-purge types)
Increased cholesterol
Hormonal changes (can lead to absence of menstrual periods, infertility, bone loss, and stunted growth)
Osteoporosis
Seizures and numbness in hands and feet
Disorganized thinking
Death (suicide is responsible for 50% of fatalities associated with anorexia)

The outlook for individuals with anorexia is variable, with recovery taking between 4 - 7 years. There is also a high chance of disease recurrence even after recovery. Long-term studies show that 50 - 70% of people recover from anorexia nervosa. However, 25% do not fully recover. Many, even after they are considered "cured," continue to exhibit traits of anorexia, such as remaining very thin and striving for perfection.
