SNL News: Jenny Slate Swears Herself In, Darrell Hammond May Be Out

BuzzSugar — Mon, 28 Sep 2009 12:30:40 -0700

New cast member Jenny Slate went from virtual unknown to Internet phenomenon on her first-ever episode of Saturday Night Live over the weekend. She dropped a now infamous "F-Bomb" during a biker-chick sketch that had her saying "freaking" about 50 times - you can barely blame her, it's a pretty easy slip, especially for someone new to live TV. Blogs immediately jumped to Slate's defense, but apparently the alarm was unnecessary. She's not getting fired, there won't be a fine since it was after 10 p.m., and Lorne Michaels supposedly isn't upset. Plus, I'd be willing to bet Miss Slate won't be making that mistake again.

In other SNL news, the show's longest running cast member's name - Darrell Hammond - was missing from the opening credits Saturday night. As recently as last week a rep for the show said he would be back in some capacity, but despite his appearance on Thursday's Weekend Update, he wasn't in any of the skits on Saturday. He's been on the show for 14 seasons and accounts for some of the cornerstone imitations - Bill Clinton, Donald Trump, and my personal favorite, Sean Connery. Between the loss of Hammond and no more Tina Fey as Sarah Palin or Amy Poehler as Hillary Clinton, there's a bit of a gaping hole in SNL's political satire.

So, what did you think of the season opener? There are some exciting hosts coming our way, but the premiere was a bit lackluster for me. Do you think Jenny Slate should face any sort of punishment for her slip up, or is it all much ado about nothing?

In case you missed it, check out the Jenny Slate clip below (language NSFW, obviously) when you read more.

Make Your Child the (Rice Krispies) Apple of Her Teacher's Eye

babysugar — Thu, 03 Sep 2009 11:00:23 -0700

What does every teacher get on the first day of school? An apple. Smiling faces would be more than enough for any educator, but parents often usher them in with a less than shiny fruit that ends up in the teacher's lounge. In an effort to do something fun the night before my daughter's very first day of preschool, together we made Rice Krispies apples that I hope won't be tossed into the compost.

To see how to make these tasty delights, read more.

Using the same ingredients (plus one) that you use for regular Rice Krispies treats, melt the marshmallows and butter in a pan or bowl. Add some red gel dye to the mix. When the mixture is a lush red, add the cereal to the mix and stir. Instead of pouring the mixture into a pan, make baseball size balls and lay them out in pans that can be refrigerated. Once they have cooled off for a little bit, take them out and sculpt them into apple molds. For my stem and leaf, I used a diced up caramel and half of a green sugar candy. Using a straw, poke a small hole on top and add a leaf and a stem. Wrap it up in cellophane and tie a ribbon around it. Attach a card with your child's name and that teacher will be begging for apples year-round!

Before and After: A Dull Bath Blossoms

CasaSugar — Thu, 27 Aug 2009 10:00:29 -0700

When faced with a dull and drab half bathroom, it's easy to ignore it, since the work to transform the space often seems daunting. However, crafty lady Singalala took her dull and drab bathroom from an eyesore to a standout in one weekend! She writes, "I have been living in my rental house for two and a half years now. I live in the Netherlands and for small, rental houses it is customary to have only one toilet, in the hallway. The shower or bath is usually separate. My toilet is under my staircase and is very, very small. Besides this, my toilet was old, the grout of the floor was loose and it had a big hole where the ventilation pipe was. The lightbulb was attached to the wall with a weird construction. The tap was full of limescale and was missing most of its chrome. The pipe for the water was exposed and painted in a bad shade of beige. The summary: not very pretty."

To see how Singalala turned it around, read more.

Using stencils and a bright shade of paint, Singalala completely transformed this bathroom into something beautiful. She raves, "I love my toilet now! It turned out much better than I imagined, and on a budget. I only paid for the accessories, tap, mural transfers and the metal paint. The rest was free or were leftovers from other projects around the house. And it only took me a weekend! My boyfriend was on holiday and was very pleasantly surprised when he returned."

Très Bizarre: Bagel Face Body Modification

TresSugar — Tue, 07 Jul 2009 11:15:00 -0700

Would you like a lox schmear with that bagel in your forehead?

Club kids in Japan are kicking extreme body modification up a notch by having lumps and bumps injected into their foreheads (and other body parts) via saline inflations or injections of saline into bags that are inserted under the skin. These self-inflicted deformations (like the bagel face saline implantations above) look insane, but they can be deflated by the next day. Want to find out about other body modifications? read more.

Extreme body modification isn't new. A search led me to an illuminating list of body modifications, illuminating because they range from the mainstream and mundane to the culturally specific to the OMG they do not do that! You might be surprised, for example, that getting your ears pierced or practicing body building is considered body modification, but technically, that's what those are.

Culturally specific practices of body mods include the old Chinese practice of foot binding or Kayan women with stacked neck rings. And then there are modern body modifications I'd rather not think too much about: scrotal implants, eyeball tattooing, tongue-splitting, and the baffling practice of trepanation, or drilling a hole into the skull.

We live in a world where people have plastic surgery to conform to certain ideals of beauty, so even though I would never have a saline inflation put in my forehead to look like I have a bagel in it (and I would probably gasp if I saw someone who did), I think there's something interesting about body modifications to debeautify or to look nonhuman (like the horns or wings you can get through plastic surgery to look like devils or angels).

Is all this too freaky for you, or do you think it's cool?

Maxed Out: Couple Spends Three Times Their Monthly Income

SavvySugar — Mon, 01 Jun 2009 12:00:29 -0700

This episode of Maxed Out features Julia, 28, and Mike, 30, a couple on the fast track to losing everything. All the big financial moments arrived at once for Mike and Julia - they have two mortgages and a baby, plus a ton of unmanageable debt. They're living in the townhouse they purchased before their condo sold, on the assumption that the condo would sell immediately.

It has been on the market for almost three months, and they're depleting their savings by covering both mortgages. Mike and Julia only have another month before they run out of savings and face foreclosure. Find out more about their messy financial situation when you read more.

Julia and Mike currently bring in about $50,000 a year - she has a sales job that's 100 percent commission, so Mike took paternity leave and is earning a reduced salary during his time at home. Mike's dad took out a $65,000 credit line to help them, but they're still in deep trouble, and financial guru Allison Griffiths takes a deeper look at their story.

The couple is shocked when Allison announces they're spending three times their monthly income. Their monthly expenditures average $15,400 a month, which means they're ending with a $10,000 shortfall every month. After going through their paperwork and learning more about their habits, Allison finds that it's not the condo that got them into trouble; it's their spending. The condo is just digging a deeper hole.

If Allison can't knock some spending sense into them, Mike and Julia's $90,000 debt (without their mortgages) will balloon into $160,000 within one year. With her guidance, the couple is able to knock out their shortfall (not too unmanageable when you see they were spending $1,500 a month on entertainment) and they're finally able to pay back Mike's dad with the sale of their condo. Mike and Julia are on the road to a more stable future, with only one mortgage and a realistic approach to spending.

Skin wrinkles and blemishes

HEALTH GUIDE REFERENCE FROM A.D.A.M

Highlights

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.

Are You Outraged by $18 Billion in Wall Street Bonuses?

LibertySugar — Fri, 30 Jan 2009 06:00:23 -0800

If you still manage to have a job on Wall Street, you might not realize that the good ol' days are over. Yesterday news broke that Wall Street bankers gave themselves $18.4 billion in bonuses last year - that's the same amount they received in 2004. President Obama angrily reacted, saying:

That is the height of irresponsibility. It is shameful, and part of what we’re going to need is for folks on Wall Street who are asking for help to show some restraint and show some discipline and show some sense of responsibility. The American people understand that we’ve got a big hole that we’ve got to dig ourselves out of, but they don’t like the idea that people are digging a bigger hole even as they’re being asked to fill it up.

Obama continued by complaining that his office shouldn't have had to pressure CitiBank against buying a $50 million private jet, because "they should know better."

The big bonuses shouldn't come as a surprise. In October, Time reported that thanks to the government's help, bankers and traders wouldn't face dismal cuts in bonuses. Without help, they could have seen bonus compensation drop 70 percent.

Detached retina

Retinal detachment repair - series

HEALTH GUIDE REFERENCE FROM A.D.A.M

Definition

Retinal detachment repair is eye surgery to place a detached retina back into its normal position.

A detached retina means the light-sensitive tissue in the back of the eye has separated from its supporting layers.

Alternative Names

Scleral buckling; Vitrectomy; Pneumatic retinopexy; Laser retinopexy

Description

Most detachment repair operations are urgent. A detached retina lacks oxygen, which causes cells in the area to die. This can lead to blindness.

If holes in the retina are found before a detachment occurs, an opthalmologist can close the holes using a laser. This is usually done in the doctor's office.

If the retina has just started to seperate, a procedure called pneumatic retinopexy may be done to repair it. Pneumatic retinopexy (gas bubble placement) is also usually an office procedure. The health care provider injects a bubble of gas into your eye. You will be positioned so the gas floats up against the hole in the retina and pushes it back into place. The surgeon will use a laser to permanently seal the hole.

More severe detachments require more advanced surgery. There following procedures are done in a hospital or outpatient surgery center:

The scleral buckle method bends the wall of the eye inward so that it meets the hole in the retina. Scleral buckling can be done under local or general anesthesia
The vitrectomy procedure uses very small instruments inside the eye to pull the retina forward. Most vitrectomies are done under local anesthesia.

For some complex detachments, both procedures may be done during the same operation.

Indications

Retinal detachments do not improve without treatment. Repair is necessary to prevent permanent vision loss.

The urgency of the surgery depends on the location of the detachment. If the detachment has not affected the central vision area (the macula), surgery should be done quickly, usually the same day. This is necessary to prevent further detachment of the retina.

If the macula detaches, the surgery can still be done, but the visual result will not be as good. If the macula has already detached, there is less urgency. Surgeons can wait a week to 10 days to schedule surgery.

Risks

Risks for retinal detachment surgery may include:

Detachment not completely fixed (may require additional surgeries)
Increase in eye pressure (elevated intraocular pressure)
Bleeding
Infection

General anesthesia may be required. The risks for any anesthesia are:

Reactions to medications
Problems breathing

Expectations after surgery

The chances of successful reattachment of the retina depend on the number of holes, their size, and whether there is scar tissue in the area.

Most of the time, the retina can be reattached with only one operation, although some people need several surgeries. Less than 10% of detachments cannot be repaired. Failure to repair the retina always leads to poor or no vision in the eye.

After surgery, the quality of vision depends on where the detachment occurred:

If the central area of vision was not involved, vision will usually be very good.
If the central area of vision was involved for less than 1 week, vision will usually be improved, but not 20/20 (normal).
If the central area of vision was detached for a long time, vision will return, but it will not be sharp.

Convalescence

The procedures usually do not require an overnight hospital stay.

You will need to limit activities for some time.

If the doctor repaired the retina using the gas bubble procedure, you must keep your head face down or turned to one side for several weeks. It is important to maintain this position so the gas bubble pushes the retina in place. Patients with a gas bubble in the eye may not fly.

Casa Beta: Clorox Green Works Wipes

CasaSugar — Thu, 19 Feb 2009 09:00:27 -0800

I've always been skeptical about the power of wipes; be it cleaning a baby's bottom or the face of Yours Truly, I've never believed they can get the job done. So, when I tested out the new Clorox Green Works Natural Cleaning Wipes, I held my expectations low. But my experience with Clorox's eco-friendly Green Works line, which is all made of plant- and mineral-based ingredients, had been wonderful, so I had hope. To hear what I thought of this product, read more.

As it turns out, these wipes far exceeded my expectations. I've been using them for a week or so to clean up everything from spills and messes in the kitchen to dust in the living room to soap scum in the bathroom. They've proved to be a sort of paper towel with super powers. Not only do they absorb spills, but they pick up crumbs and small particles. They clean each surface as you wipe, not only cleaning up your mess but cleaning your countertops and floors as well. They are quite moist though, so you have to let your surfaces air dry after use.

Beyond that, they're made from over 99 percent natural ingredients that are biodegradable, which eases my environmental concerns about toxic cleaning solutions and piling up waste. They're also scented with essential oils, which leave a fresh, lemony fragrance in their wake.

My only issue with the wipes was the packaging. Though the container itself is recyclable, I had difficulty with its engineering. Each wipe is supposed to slip through a small hole in the cap, and the next one should pop up after you've pulled the first. Try as I might, the functionality failed on me each time, which was quite frustrating. I ended up removing the cap each time, which slowed down my cleaning routine. Of course, I'm happy to deal if it means using an eco-friendly product that cleans effectively.

Migraine Surveys

About 17.1% of women and 5.6% of men suffer migraines, according to the 2007 American Migraine Prevalence and Prevention survey. Nearly a third of respondents reported 3 or more migraine attacks per month. Over half were severely impaired or needed bed rest during attacks. Although many patients met the criteria for preventive medication, only a small percentage actually received it.
About 20% of patients with migraine take potentially addictive opioid and barbiturate drugs, even though these drugs have not been approved by the Food and Drug Administration (FDA) for migraine treatment, according to a 2007 survey commissioned by the U.S. National Headache Foundation.

FDA Actions

The opioid drug fentanyl (Fentora) should not be prescribed "off-label" to patients with migraine or other severe headaches, warns the FDA, following several reports of drug-related deaths. Fentanyl is approved only for treating cancer pain.
In 2007, the FDA pulled 15 unapproved ergotamine preparations off the market because they lacked a warning label describing the risks for serious drug interactions.

Migraines in Adolescents

Many adolescents may stop having migraines, or transition to less severe types of headaches, when they reach adulthood, suggests a small 2006 study in Neurology.
Zolmitriptan (Zomig) nasal spray appears to be safe and effective for adolescent migraine, indicates a 2007 study in Pediatrics. Zolmitriptan, like all migraine drugs, is currently approved only for adults.

Sumatriptan-Naproxen Combination

A combination of the triptan drug sumatriptan (Imitrex) and the nonsteroidal anti-inflammatory drug naproxen (Aleve) works better for migraine pain relief than either drug alone, according to a 2007 study in the Journal of the American Medical Association.

Introduction

The pain from a headache does not start from inside the brain. (The brain itself can not feel pain.) Instead, headache pain begins in one or more of the following locations:

The tissues covering the brain
The structures at the base of the brain
Muscles and blood vessels around the scalp, face, and neck

Headache is generally categorized as primary or secondary.

Primary Headache. A headache is considered primary when a disease or other medical condition does not cause it.

Tension headache is the most common primary headache and accounts for 90% of all headaches. [See In-Depth Report # 11: Tension headaches.]
Neurovascular headaches are the second most common primary headaches. This type includes migraines and cluster headaches. [See In-Depth Report # 99: Cluster headaches.] Such headaches are caused by an interaction between blood vessel and nerve abnormalities.

Headaches are usually caused by muscle tension, vascular problems, or both. Migraines are vascular in origin, and may be preceded by visual disturbances, loss of peripheral vision, and fatigue. Over-the-counter pain medications can relieve most headaches.

Secondary Headache. Secondary headaches are caused by other medical conditions, such as sinusitis, neck injuries or abnormalities, and stroke. About 2% of headaches are secondary headaches caused by abnormalities or infections in the nasal or sinus passages. [See "Causes of Secondary Headaches," in this report.]

It is not uncommon for someone to experience a combination of headache types.

Migraine is now recognized as a chronic illness, not simply as a headache. About 28 million people suffer from migraines annually. They are often classified by whether or not auras (seeing bright "spots" or "stars") accompany them:

Common migraines are without auras. About 75% of migraines are the common type.
Classic migraines are those with auras.

A person may experience one or the other at different times.

In general, there are four phases to a migraine (although they may not all occur in every patient): The prodrome phase, auras, the attack, and the postdrome phase.

Prodrome. The prodrome phase is a group of vague symptoms that may precede a migraine attack by several hours, or even a day or two. Prodrome symptoms include:

Sensitivity to light or sound
Changes in appetite
Fatigue and yawning
Malaise
Mood changes
Food cravings

Auras. Auras are sensory disturbances that occur before the migraine attack in 1 in 5 patients. Visually, auras are referred to as being positive or negative:

Positive auras include bright or shimmering light or shapes at the edge of their field of vision called scintillating scotoma. They can enlarge and fill the line of vision. Other positive aura experiences are zigzag lines or stars.
Negative auras are dark holes, blind spots, or tunnel vision (inability to see to the side).
Patients may have mixed positive and negative auras. This is a visual experience that is sometimes described as a fortress with sharp angles around a dark center.

Other neurologic symptoms may occur at the same time as the aura, although they are less common. They include:

Speech disturbances
Tingling, numbness, or weakness in an arm or leg
Perceptual disturbances such as space or size distortions
Confusion

Migraine Attack. If untreated, attacks usually last from 4 - 72 hours. A typical migraine attack produces the following symptoms:

Throbbing pain on one side of the head. The word migraine, in fact, is derived from the Greek word hemikrania, meaning "half of the head" because the pain of migraine often occurs on one side. Pain also sometimes spreads to affect the entire head.
Pain worsened by physical activity
Nausea, sometimes with vomiting
Visual symptoms
Facial tingling or numbness
Extreme sensitivity to light and noise
Looking pale and feeling cold

Less common symptoms include tearing and redness in one eye, swelling of the eyelid, and nasal congestion, including runny nose. (Such symptoms are more common in certain other headaches, notably cluster headaches. In one study, however, they occurred in over 40% of migraine sufferers.)

Postdrome. After a migraine attack, there is usually a postdrome phase, in which patients may feel exhausted and mentally foggy for a while.

In some cases, patients eventually experience on-going and chronic headaches. In fact, in an analysis using two different diagnostic methods, between 87 - 90% of daily chronic headaches were actually migraines. Some doctors believe that, unless otherwise demonstrated, any chronic headache consisting of episodes of disabling pain that recur regularly over years should be considered as a migraine.

Chronic migraines may occur from overuse of migraine medications (called a rebound headache) or may develop over time (called transformed migraine).

Rebound Headache. The most common cause of chronic migraine is the rebound effect, which is a cycle caused by overuse of migraine medications. The process involves the following:

Patients typically have taken pain medication for more than 3 days a week on an ongoing basis.
When the patients stop taking medication, they experience a rebound headache.
They start taking the drugs again.
Eventually the headache simply persists, and medications are no longer effective.

Medications implicated in rebound migraines include nonprescription painkillers (acetaminophen, aspirin, ibuprofen), barbiturates, sedatives, narcotics, and migraine medications, particularly those that also contain caffeine. (Heavy caffeine use can also cause this condition.)

Transformed Migraines. In some cases, migraines themselves evolve into chronic, daily headaches called transformed migraines. Such headaches resemble tension headaches but are more likely to be accompanied by gastrointestinal distress and mental or visual disturbances and, in women, to be affected by menstrual cycles. In one study, the risk for transformed migraines were associated with other factors, including allergies, asthma, hypothyroidism, hypertension, and a daily intake of caffeine.

Migraines are defined by the number and length of attacks and whether an aura is present.

Definition of Migraines without Auras (Common Migraine). To be defined as a migraine without aura, a patient should have at least five attacks that have the following characteristics:

A. Each untreated, or unsuccessfully treated, attack must last 4 - 72 hours.

B. It must have at least two of the following four characteristics:

Pain on one side of the head
Pulsing or throbbing pain
Pain severe enough to impair or prevent daily activities
Pain must be intensified by exertion, such as walking up stairs

C. During a headache at least one of the following symptoms must also be present:

Nausea, vomiting or both
Sensitivity to light and noise

In addition, other neurologic or medical conditions that might be causing this pain must be ruled out, or, if they do occur, they are not related in time to the suspected migraine.

Definition of Migraines with Auras (Classic Migraine). To be defined as a migraine with aura, the patients must have at least two attacks that have three out of four of the following events.

At least one fully reversible aura symptom suggesting the headache starts in the cerebral cortex or brain stem.
At least one aura symptom that develops gradually over more than 4 minutes ,or two or more aura symptoms that occur in succession.
No single aura symptom that lasts more than 1 hour. (There may be successive aura symptoms that extend that time, but each one should not last more than 60 minutes.)
The headache itself may begin before, at the same time, or at an interval of no more than an hour after the aura.

As with common migraines, other neurologic or medical conditions that might be causing this pain must be ruled out or if they occur, they are not related in time to the suspected migraine.

Although migraine is considered to be a specific chronic illness, it has various presentations that occur in different individuals.

Menstrual Migraines. Migraines are often tied to a woman’s menstrual cycle. Researchers think that estrogen plays a role. About half of women with migraines report an association with menstruation. Compared to migraines that occur at other times of the month, menstrual migraines tend to be more severe, last longer, and not have auras. Triptan drugs can provide relief and may also help prevent these types of migraines.

The highest incidence of migraines typically occurs during the early follicular phase, (beginning of menstruation). A 2005 study found that women are 1.7 times more likely to have a migraine during the 2 days before menstruation begins. But, women are 2.5 times more likely to have a migraine during the first 3 days of menstruation. During this time, migraines are more likely to be severe, with symptoms that include vomiting.

Ophthalmoplegic Migraine. This very rare headache tends to occur in younger adults. The pain centers around one eye and is usually less intense than in a standard migraine. It may be accompanied by vomiting, double vision, a droopy eyelid, and paralysis of eye muscles. Attacks can last from hours to months. A computed tomography (CT) or magnetic resonance imaging (MRI) scan may be needed to rule out an aneurysm (a rupture blood vessel) in the brain.

Retinal Migraine. Symptoms of retinal migraine are short-term blind spots or total blindness in one eye that lasts less than an hour. A headache may precede or occur with the eye symptoms. Sometimes retinal migraines develop without headache. Other eye and neurologic disorders must be ruled out.

Basilar Migraine. Considered a subtype of migraine with aura, this migraine starts in the basilar artery, which forms at the base of the skull. It occurs mainly in young people. Symptoms may include vertigo (the room spins), ringing in the ears, slurred speech, unsteadiness, possibly loss of consciousness, and severe headaches.

Familial Hemiplegic Migraine. This is a very rare inherited genetic migraine disease. It can cause temporary paralysis on one side of the body, vision problems, and vertigo. These symptoms occur about 10 - 90 minutes before the headache.

Status Migrainosus. This is a serious and rare migraine. It is so severe and lasts so long that it requires hospitalization.

About 90% of people seeking help for headaches have a primary headache disorder. The balance of secondary headaches is caused by an underlying disorder that produces the headache as a symptom. Many conditions cause headaches as a symptom. Some of the most common are listed below.

Sinus Headache. Many primary headaches, including migraine, are misdiagnosed as sinus headaches. Nearly 9 in 10 patients who think they have sinus headaches actually have or probably have had a migraine. Sinus headaches occur in the front of the face, usually around the eyes, across the cheeks, or over the forehead. They are usually mild in the morning and increase during the day and are usually accompanied by fever, runny nose, congestion, and general debilitation. Sinus headaches spread over a larger area of the head than migraines, but telling the difference between these two kinds of headache is difficult, particularly if a headache is the only symptom of sinusitis. The two may even coexist in many cases. Often, the visual changes associated with migraine can rule out sinusitis, but such visual changes do not occur with all migraines. (Rarely, sinusitis can cause double vision and even vision loss, a sign of very serious infection.)

Headache Due to Neck Problems. Some headaches may be caused by abnormalities of the neck muscles resulting from prolonged poor posture (such as that caused by sitting in front of a computer keyboard or driving daily for long periods), arthritis, injuries of the upper spine, or abnormalities in the cervical spine (the spinal bones in the neck). Nerves in the neck converge in the trigeminal nerve in the face and can generate pain signals that the brain may interpret as headache. Pain is usually on one side. Even if it affects both sides of the head, it is usually more severe on one side. The quality of the headache may be similar to an aching tension headache or a mild migraine without aura.

Temporomandibular Joint Dysfunction. Temporomandibular joint dysfunction (TMJ) is caused by clenching the jaws or grinding the teeth (usually during sleep), or by abnormalities in the jaw joints themselves. The diagnosis is easy if chewing produces pain or if jaw motion is restricted or noisy. TMJ pain can occur in the ear, cheek, temples, neck, or shoulders.

Glaucoma. Acute glaucoma is caused by increased pressure in the eye and requires immediate medical attention. Throbbing pain may be felt around or behind the eyes or in the forehead. Patients have redness in the eye and may see halos or rings around lights.

Brain Tumor. Fear of having a brain tumor is common among people with headaches, but a headache is almost never the first or only sign of a tumor. Changes in personality and mental functioning, vomiting, seizures, and other symptoms are more likely to appear first. When the headache does develop, it is often worse early in the morning or may awaken sufferers during the night.

Neuralgia. Neuralgia is pain due to nerve abnormalities, which can occur in the facial area and resemble migraine or sinus headaches.

Hypertension. Although many people attribute headaches to high blood pressure, the two are rarely associated. An exception is malignant hypertension, an uncommon medical emergency, in which the blood pressure abruptly rises to extreme levels, causing damage to blood vessels in the brain, heart, and kidneys.

Strokes Caused by Blood Clots or Hemorrhages. A blood clot or hemorrhage in the brain leading to a stroke can cause a severe headache, sometimes referred to as a thunderclap headache when it is very sudden and severe. The onset of such a headache, particularly if it is associated with confusion, stupor, or other neurologic symptoms, mandates prompt medical attention. It is important to determine if a clot or bleeding is causing the stroke, since treatments are very different.

Head Injuries. It is obvious that a significant blow to the head will cause pain. Post-injury headaches, however, can reflect serious damage, ranging from skull fractures to internal bleeding.

Disorders of the Meninges. The meninges are the membranes covering the brain and the spinal cord. In very rare instances, ordinary physical strain may injure or weaken the meninges, causing a leakage of cerebrovascular fluid (the fluid that bathes the brain). This can cause severe headache and nausea, which are relieved by lying flat. The condition is very treatable. Meningitis, which is an infection or irritation of these membranes, is an uncommon but potentially serious cause of severe headache. Other symptoms include nausea and stiffness or pain in the neck.

Gynecologic Problems. Many clinicians have anecdotally linked gynecologic problems, such as ovarian cysts and menstrual disorders, to chronic headaches, and new data are emerging to support this association.

Temporal (Giant Cell) Arteritis. Certain causes of headaches are unique to the elderly, such as temporal arteritis, also called giant cell arteritis. Inflammation in arteries that carry blood to the head, neck, and sometimes the upper part of the body can cause very severe headaches. The risk for this headache is highest in people over age 70, especially among women, people of European heritage, and patients with polymyalgia rheumatica.

Miscellaneous Causes of Benign Headaches. Rapid consumption of ice cream or other very cold foods or beverages is the most common trigger of sudden headache pain. (It may be prevented by warming the food or drink for a few seconds in the front of the mouth before swallowing.) Other common benign causes of headache include eyestrain, dental problems, allergies, systemic infections, and caffeine withdrawal. Headaches may be induced by sexual activity or intense physical exertion. Leakage from spinal cord fluid is rare but can cause headaches that may be mistaken for brain tumors.

Prognosis

For many people, migraines eventually go into remission and sometimes disappear completely, particularly as they age. Estrogen decline after menopause may be responsible for remission in some older women. One study reported that the following people with migraines (called migraineurs) have a better chance of remission if they have:

A family history of migraine with aura
Migraines that are not triggered by light
No other primary headaches

According to another study, a history of head trauma or oral contraceptive use predicted a poorer long-term outlook.

Migraine or severe headache is a risk factor for stroke in both men and women, especially before age 50. About 19% of all strokes occur in people with a history of migraine. Research indicates that migraine also increases the risk for other types of heart problems.

Migraine with aura carries a higher risk for stroke than without auras. A 2005 analysis of over 12,000 participants from an atherosclerosis risk study found that migraine with aura was significantly associated with higher risk for stroke and transient ischemic attacks. Another 2005 study suggested that people who experience migraine with aura tend to have more cardiovascular risk factors than people without migraine. These risk factors included worse cholesterol profile, higher blood pressure, early history of heart disease and stroke, and greater likelihood of using oral contraceptives.

Results from a 2005 study showed that women who have migraine with aura are at increased risk of ischemic stroke compared with those who do not have auras and those who have non-migraine headaches. Women under age 55 had the highest risk, with more than double the risk. A 2006 Women’s Health Study of women ages 45 and older found that migraine with aura also increases women’s risk for heart attack, angina, and death due to ischemic heart disease (in which blood flow is decreased due to narrowing of coronary arteries). Migraine without aura did not increase heart disease and stroke risks.

Studies suggest specific stroke risk factors for younger women with migraines, particularly those with auras. Smoking, high blood pressure, and birth control pills considerably raise one's risk 10 - 20 times.

Researchers are also studying the relationship between patent foramen ovale (PFO) and migraine. A PFO is a hole in the wall dividing the upper left and right heart chambers. About half of patients with PFO have severe migraines with aura. Researchers are investigating whether surgical repair of the PFO may help control migraines in patients with this heart condition.

Migraine and other headaches associated with aura may increase the risk for retina damage (retinopathy) among middle-aged people, suggests a 2007 study.

The negative impact of migraines on quality of life, families, and even work productivity is significant and often underrated as a serious complication. Studies indicate that people with migraines have poorer social interactions and emotional health than patients with chronic medical illnesses, including asthma, diabetes, and arthritis. Anxiety (particularly panic disorders) and major depression are also strongly associated with migraines.

A 2005 National Headache Foundation-sponsored survey of migraine sufferers reported that:

90% of people with migraines could not function normally on the day of a migraine attack
80% experienced abnormal sensitivity to light and noise
75% experienced nausea and vomiting
30% required bed rest
25% missed at least 1 day of work due to migraine in past 3 months

Effect of Pregnancy on Migraines. In one study, pregnant women with tension or migraine headaches experienced 80% fewer headaches, usually after the end of the first trimester.

Effect of Migraine on the Pregnant Woman or Fetus. Migraine headaches do not pose any added risks during pregnancy to the mother or the fetus, although women with migraines may be at higher risk for having smaller (but not premature) babies.

Causes

Until recently, the general theory on the migraine process rested solely on the idea that abnormalities of blood vessel (vascular) systems in the head were responsible for migraines. Now, however, doctors tend to believe that migraine starts with an underlying central nervous system disorder. When triggered by various stimuli, this disorder sets off a chain of neurologic and biochemical events, some of which subsequently affect the brain's vascular system. No experimental model fully explains the migraine process.

There is certainly a strong genetic component in migraine with or without auras. Researchers have located a single genetic mutation responsible for the very rare familial hemiplegic migraine, but several genes are likely to be involved in the great majority of migraine cases. Numerous chemicals, structures, nerve pathways, and other players involved in the process are under investigation.

Central Nervous Disorder. One theory that attempts to integrate many of the known events in the migraine process is as follows:

Stress or some unknown factor triggers the release of certain protein fragments called peptides (Substance P, calcitonin gene-related peptide, and others).
These peptides dilate blood vessels and produce an inflammatory response that triggers over-excitation of the nerve cells in the trigeminal pathway. [This nerve pathway runs from the brain stem to the head and face. These nerves spread to the meninges (the membrane covering of the brain).]
While the brain itself is insensitive to pain, the meninges and blood vessels around the brain are sensitive to pain. Some doctors suggest that pain occurs when blood drains from the center of the head to the blood vessels around the brain.
Auras are believed to be a response to blood flow changes that cause a rapid reduction in brain activity that reaches the cerebral cortex (the outer layer of the brain), referred to as spreading depression. This effect may be visualized as an electrical wave spreading through the brain just as a wave of water is caused by the dropping of a pebble. Some research suggests that in people with auras, the cortical spreading depression itself activates the inflammation in the trigeminal nerves that triggers pain in the meninges.

One theory of the cause of migraine is a central nervous system (CNS) disorder. The CNS consists of the brain and spinal cord. In migraine, various stimuli may cause a series of neurologic and biochemical events that affect the brain's vascular system.

Abnormal Calcium Channels. Some migraines may be due to abnormalities in the channels within cells that transport the electrical ions calcium, magnesium, sodium, and potassium. Calcium channels appear to play a particularly critical role in migraine:

Calcium channels regulate the release of serotonin, an important neurotransmitter in the migraine process. (A neurotransmitter is a chemical messenger that allows communication between nerves in the brain.)
Magnesium interacts with calcium channels, and magnesium deficiencies have been detected in the brains of patients with migraine.
Calcium channels also play a major role in cortical spreading depression, the brain event that appears to be important in migraine symptoms.

Some patients with migraines may inherit one or more factors that impair calcium channels, making them susceptible to headaches. For example, mutations in a gene that encodes calcium channels appears to be responsible for familial hemiplegic migraine.

Researchers are also investigating factors that are common to both migraines and tension-type headaches. Some research suggests that both problems may result from a continuum of abnormalities in the central nervous system (the nerves in the brain and spine). Such changes trigger a progression of symptoms starting with mild sensations, developing into tension headache, and finally, progressing in some people to a migraine.

Serotonin and Other Neurotransmitter Levels. Neurotransmitters are chemical messengers in the brain. Serotonin is a neurotransmitter (chemical messenger in the brain) that is important for sleep, well-being, and other factors that affect quality of life. Abnormalities in serotonin levels have been observed in both tension-type and migraine headache sufferers. Altered levels of other neurotransmitters, importantly dopamine and stress hormones, also occur with migraine and tension-type headaches.

Dopamine, for example, may act as a stimulant of the migraine process. Some evidence suggests that certain genetic factors make people over-sensitive to the effects of dopamine, which include nerve cell excitation. Such nerve-cell over-activity could trigger the events in the brain leading to migraine. The prodromal symptoms (mood changes, yawning, drowsiness), for example, have been associated with increased dopamine activity. Dopamine receptors are also involved in regulation of blood flow in the brain.

Reduced Magnesium Levels. Magnesium deficiencies have been observed in people with both tension-type and migraine headaches. Researchers have noted a drop in magnesium levels before or during a migraine attack. Magnesium plays a role in nerve cell function. Reduced levels could be a destabilizing factor, causing the nerves in the brain to misfire, possibly even accounting for the auras that many sufferers experience.

Nitric Oxide. Other research suggests that over-excitable neurons release nitric oxide, a small molecular messenger that may be important in triggering in most primary headaches (tension-type, cluster, and migraines). Elevated levels have been observed in blood cells of patients with tension-type headache. Some evidence suggests that the release of this molecule in blood vessels may activate nerve pathways in the brain, muscles, or elsewhere and increase pain.

Estrogen Fluctuations in Women. Tension-type headaches and migraine headaches are slightly more common in females during adolescence and adulthood. Most likely hormone fluctuations, rather than whether levels are elevated or low, trigger headaches. Some research suggests that fluctuations in estrogen levels may impact levels of serotonin and other pain-modulating substances that affect these headaches.

Inflammation in the Maxillary Nerve. Early studies suggest that some chronic tension-type and migraine headaches may be caused by inflammation in the nerve that runs behind the cheekbone (the maxillary nerve) -- not around the covering of the brain. In fact, some work using ice water for reducing swelling in areas of the gums above the last upper molars has relieved some severe migraine and tension-type headaches.

A wide range of events and conditions can alter conditions in the brain that bring on nerve excitation and trigger migraines. They include, but are not limited to:

Emotional stress
Intense physical exertion (exercise, lifting, and even bowel movements or sexual activity)
Abrupt weather changes
Bright or flickering lights
High altitude
Travel motion
Lack of sleep
Low blood sugar and fasting
Chemicals found in certain foods. More than 100 foods may potentially trigger migraine headache. Caffeine is one such trigger. Caffeine withdrawal can also trigger migraines in people who are accustomed to caffeine. Experts recommend that patients keep a headache diary to track which foods trigger migraine.

Risk Factors

About 30 million Americans suffer from migraine headaches. They affect about 17% of all women and 6% of men. In fact, 70% of all migraine sufferers are women. Migraine is more prevalent among women throughout the world and in every culture. Although the incidence of migraine is similar for boys and girls during childhood, it increases in girls after puberty. Most people with migraine have 1 - 4 attacks per month.

Hormone Fluctuations in Women. Most migraines in women develop during the hormonally active years between adolescence and menopause. Fluctuations of estrogen and progesterone, rather than their presence, appear to increase the risk for migraines and their severity in some women.

About half of women with migraines report headaches associated with their menstrual cycle, although true menstrual migraines may actually be less common. True menstrual migraines tend not to have auras and to increase in prevalence between 2 days before and 5 days after the onset of period.
The first 3 months of pregnancy can worsen migraines in some women, although one study reported that pregnancy had little effect one way or the other on severity in most women with chronic headaches.
Women whose migraines are affected by pregnancy or menstruation are also likely to have worse migraines if they take oral contraceptives or hormone replacement therapies.

General Age of Onset. More than 20% of adults with migraines report that their headaches started before age 10, and over 45% say they started before age 20. The incidence of migraine declines in both men and women after age 40.

Migraine in Children. Migraine headaches occur in all ages and can appear in children as young as 4 years of age. Migraines in children are equally prevalent in boys and girls. Studies estimate that about 4 – 10% of all children suffer from migraine. Research indicates that overweight children may be especially susceptible to headaches, although this association is most likely due to poor nutrition and lack of exercise rather than excess weight. Children who have sleep problems, especially difficulty falling asleep, may also be more prone to migraines.

A small 2006 study indicated that some adolescents with migraine may eventually grow out of their condition. By the end of the 10-year study, 38% of patients had stopped having migraines, and 20% had transitioned into less severe tension-type headache. Children with a family history of migraine were more likely to continue having migraines.

Migraine Onset in Older Adults. Although uncommon, late-life migraine occurs in about 1% of the population, usually in men. In such cases, it often occurs as migraine with visual disturbances but without headache.

Migraine headaches can be inherited. If both parents suffer from migraines, their children have a 75% chance of getting them. When only one parent gets migraines, there is a 50% chance that children will be afflicted.

Caucasians have a higher risk than either African-Americans or Asians. Worldwide, one study reported that migraines are most common in North America. They are slightly less prevalent in South America and Europe and far less common in Asia and Africa. Investigators believe that the differences are due to genetic variations, not lifestyle factors.

People with migraine have a higher incidence of other medical conditions, including:

Asthma and allergies. These conditions have also been associated with a higher risk for conversion from having periodic migraines attacks to a chronic form (transformed migraines).
H. pylori infection. People who are infected with the bacteria H. pylori, the major cause of peptic ulcers, are at higher risk for migraines.
Epilepsy. Patients with epilepsy are twice as likely to have migraines as the general population.
Fibromyalgia
Systemic lupus erythematosus
Raynaud syndrome
Mitral valve prolapse
Narcolepsy

One study suggested that women with migraines tend to over-respond to stressful situations. In the study, they were more likely than other women to be diligent, conscientious, and overly sensitive to pressure from others. More likely, however, a person's family history of migraine, rather than any personality trait, is the important risk factor.

Diagnosis

Anyone, including children, who has recurring or persistent headaches should consult a doctor. There are no blood tests or imaging techniques that can be used to diagnose migraine headaches. A diagnosis will be made on the basis of history and physical exam, and, if necessary, tests may be necessary to rule out other diseases or conditions that may be causing the headaches. It is important to choose a doctor who is sensitive to the needs of headache sufferers and aware of the latest advances in treatment.

For an accurate diagnosis, the patient should describe:

Duration and frequency of headaches
Recent changes in their character
Location of pain
Type of pain (throbbing or steady pressure)
Intensity of the headache
Associated symptoms, such as visual disturbances or nausea and vomiting
Behaviors during a headache. This may help distinguish between migraine and tension headaches. The predominant behavior with tension headaches is massaging the scalp, temples, or the nape of the neck. A person with migraines is more apt to use compression (such as tying a scarf around the forehead and temples) or to apply cold. They also tend to isolate themselves, lie down, induce vomiting, and use more pillows than usual. (None of these maneuvers do much good in relieving either headache, unfortunately.)

The presence of auras or other visual disturbances do not always identify migraine:

Patients with severe sinus infections may experience double vision or visual loss. (This is an emergency condition, since it indicates the infection has spread to areas around the eyes.)
Many migraine sufferers have no auras.
Many elderly people with late-onset migraine have auras but no pain.

The patient should try to recall what seems to bring on the headache and anything that relieves it. Keeping a headache diary is a useful way to identify triggers that bring on headaches. Some tips include:

Note all conditions, including any foods eaten, preceding an attack. Often two or more triggers interact to produce a headache. For example, a combination of weather changes and fatigue can make headaches more likely than the presence of just one of these events.
Keep a migraine record for at least three menstrual cycles. For women, this can help to confirm or refute a diagnosis of menstrual migraine.
Track medications. This is important for identifying possible rebound headache or transformed migraine.
Attempt to define the intensity of the headache using a number system, such as:

1 = Mild, barely noticeable

2 = Noticeable, but does not interfere with work/activities

3 = Distracts from work/activities

4 = Makes work/activities very difficult

5 = Incapacitating

The patient should report any other conditions that might be associated with headache, including but not limited to:

Any chronic or recent illness and their treatments
Any injuries, particularly head or back injuries
Any uncharacteristic dietary changes
Any current medications or recent withdrawals from any drugs, including over-the-counter or natural remedies.
Any history of caffeine, alcohol, or drug abuse.
Any serious stress, depression, and anxiety.

The doctor will also need a general medical and family history of headaches or diseases, such as epilepsy, that may increase their risk. Migraine tends to run in families.

In order to diagnose a chronic headache, the doctor will examine the head and neck and will usually perform a neurologic examination, which includes a series of simple exercises to test strength, reflexes, coordination, and sensation. The doctor may ask questions to test short-term memory and related aspects of mental function.

Diagnosing the cause of persistent daily headache is difficult, even for expert doctors. Studies report that people who visit the emergency room with disabling headache are often misdiagnosed as tension-type headaches instead of migraines. It is important to choose a doctor who is sensitive to the needs of headache sufferers and aware of the latest advances in treatment.

Extensive testing may be advised for anyone with a chronic, daily headache. Tracking times of medications, withdrawal, and headache, using the headache diary, is usually very helpful in diagnosis.

Differentiating Rebound Headaches from Transformed Migraines. Migraines that evolve to chronic headaches must be first differentiated between natural transformed migraines and rebound headaches (the most common cause of persistent migraines):

A transformed migraine is usually more consistent in its severity and its location than a rebound headache.
Transformed migraines are less sensitive to triggers than rebound headaches.

Differentiating Transformed from Tension Headaches. Once rebound headache is ruled out, the doctor must then differentiate natural transformed migraines from tension headaches:

In most cases of transformed migraine (but not tension headache), gastrointestinal or neurologic symptoms are present.
Transformed migraine is also frequently associated with menstrual fluctuations in women.

Imaging tests of the brain may be recommended under the following circumstances:

If the results of the history and physical examination suggest neurologic problems.
For patients with headaches that wake them at night.
For new headaches in the elderly. In this age group, it is particularly important to first rule out age-related disorders, including stroke, hypoglycemia, hydrocephalus, and head injuries (usually from falls).
For patients with worsening headaches.

They are not recommended for patients with migraine and with no other abnormal indications.

The following tests may be used:

A CT (computed tomography) scan may be ordered to rule out brain disorders or headaches caused by chronic sinusitis.
X-rays and other tests may also be used if sinusitis is strongly suspected.
A neck x-ray can reveal arthritis or spinal problems.
Other imaging tests include an MRI (magnetic resonance imaging), EEG (electroencephalogram), lumbar puncture, ultrasound testing, and cerebral angiography, positron emission tomography (PET), and single-photon emission computed tomography (SPECT). These tests are only performed if there is reason to suspect an underlying disease or as part of clinical studies.

A CT (computed tomography) scan is a much more sensitive imaging technique than x-ray, allowing high definition of not only the bony structures but also the soft tissues. Clear images of organs and structures, such as the brain, muscles, joints, veins and arteries, as well as of tumors and hemorrhages, may be obtained with or without the injection of contrasting dye.

Headaches indicating a serious underlying problem, such as cerebrovascular disorder or malignant hypertension, are uncommon. (It should again be emphasized that a headache is not a common symptom of a brain tumor.) People with existing chronic headaches, however, might miss a more serious condition by believing it to be one of their usual headaches. Such patients should call a doctor promptly if the quality of a headache or accompanying symptoms has changed. Everyone should call a doctor for any of the following symptoms:

Sudden, severe headache that persists or increases in intensity over the following hours, sometimes accompanied by nausea, vomiting, or altered mental states (possible hemorrhagic stroke).
Sudden, very severe headache, worse than any headache ever experienced (possible indication of hemorrhage or a ruptured aneurysm).
Chronic or severe headaches that begin after age 50.
Headaches in the back of the head accompanied by other symptoms, such as memory loss, confusion, loss of balance, changes in speech or vision, or loss of strength in or numbness or tingling in arms or legs (possibility of small stroke in the base of the skull).
Headaches after head injury, especially if drowsiness or nausea are present (possibility of hemorrhage).
Headaches accompanied by fever, stiff neck, nausea and vomiting (possibility of spinal meningitis).
Headaches that increase with coughing or straining (possibility of brain swelling).
A throbbing pain around or behind the eyes or in the forehead accompanied by redness in the eye and perceptions of halos or rings around lights (possibility of acute glaucoma).
A one-sided headache in the temple in elderly people; the artery in the temple is firm and knotty and has no pulse; scalp is tender (possibility of temporal arteritis, which can cause blindness or even stroke if not treated).
Sudden onset and then persistent, throbbing pain around the eye possibly spreading to the ear or neck unrelieved by pain medication (possibility of blood clot in one of the sinus veins of the brain).

Treatment Approaches

Many effective headache remedies are available for treating a migraine attack. Still, a study that analyzed over 800,000 cases of migraine reported that most migraines are not treated according to any recommended guidelines. In the study, 30% of patients were treated with potentially addictive opioids -- most often merepidine (Demerol). Furthermore, 70% of these patients were not offered effective and available anti-migraine drugs. Anti-nausea drugs that have no effect on headaches were used six times more often than drugs that reduce headaches.

A 2007 survey of migraine sufferers, commissioned by the U.S. National Headache Foundation, reported that 20% of patients are prescribed non-approved medications containing opioids or barbiturates. The survey also indicated that patients who take non-approved drugs are more likely to experience drug-related side effects. For mild migraines, non-prescription treatments (Excedrin Migraine, Advil Migraine, Motrin Migraine Pain) are the best first choice. For severe migraines, doctors recommend starting with a triptan drug.

Preventive treatment, used to stop migraine attacks before they happen, may help many patients. According to another 2007 survey, more than 1 in 4 patients with migraine are candidates for preventive therapy but most do not receive it.

As many as 30% of patients with migraine also have accompanying headaches resulting from tension, drugs, infections, or other causes. It is important to distinguish between headache types in order to determine appropriate treatment.

General Guidelines. The general goals of treatment are:

Choose drugs with as few side effects as possible. Patients should talk to their doctors about various methods for administering the medication (pills, injections, nasal spray, or rectal suppositories) and begin with the one they believe will be the least distressing.
Treat the attack rapidly, within an hour of symptom onset if possible. Start with low doses, and build up dosage slowly.
Try to minimize the use of back-up or "rescue medications." (A rescue medication is typically a narcotic opiate drug, which is used for pain relief when other medications fail.)
Try to guard against rebound effect. Nearly all drugs used for migraine can cause rebound headache, and patients should not take any the drugs for longer than 2 days per week.
It may take 2 - 4 months for any drug to be effective.

Stepped-Up Treatment Approach. Some doctors recommend a stepped-up treatment course for an acute migraine attack. This involves starting with the least potent treatments and taking increasingly more powerful drugs until the pain stops. In this approach, patients may need up to five different medications to achieve pain relief. A typical stepped-up approach is the following:

The patient should first use nonprescription pain relievers (NSAIDs, Excedrin Migraine) and stress-reduction techniques.
If these are not effective within 2 hours, the patient should take migraine-specific drugs. Triptans are the first choice, then ergot derivatives.
Patients with migraines associated with severe nausea or vomiting may use injected or rectally administered drugs. Nausea itself should be treated with specific anti-nausea drugs, such as metoclopramide (Reglan).
If migraine medications fail to relieve symptoms within 4 hours, rescue drugs (opioids, corticosteroids) may be used.

Stratified Approach. Many doctors and patients now prefer the stratified approach. The doctor first estimates the severity of the patient's condition based on his or her history. Then, depending on the severity of a typical attack, the doctor decides whether the patient should start with more or less powerful drugs at the first signs of the migraine:

Patients with less disabling migraines start with general pain relievers.
Patients with a history of moderate-to-severe migraines start with migraine-specific prescription medicine, such as a triptan, at the onset of mild pain.

Some studies report dramatic relief with the stratified approach. In one study, zolmitriptan, a newer triptan, reduced the intensity of headaches within 2 hours in 70% of patients with moderate pain but only in 44% of those with severe headaches.

Side effects can be severe with many migraine drugs, although newer drugs, such as the recent generation triptans, may provide effective early relief without significant side effects.

Studies estimate that between 5 - 10% of children have migraines but that the disorder is underdiagnosed in children. An interesting study reported that when children drew pictures in response to their doctors' questions about their migraines, the doctors were able to tell the difference between migraine and non-migraine headaches in the majority of cases.

Symptoms in Children. The standard diagnostic criteria for migraine in adults may apply to only about two-thirds of migraines in children and adolescents. For example, doctors have seen the following differences:

Headaches tend to last for a shorter time (as little as an hour) in children.
Migraine pain tends to occur in the face and on both sides of the head in two-thirds of child patients.
Children often have a form of migraine known as a migraine equivalent or abdominal migraine, which does not cause a headache at all. Instead, children experience periodic bouts of nausea and vomiting (called cyclic vomiting syndrome) or other secondary symptoms found in adult migraine, such as a reaction against light or sound. Cyclic vomiting may occur in nearly 2% of school-aged children with or without a migraine association.
Migraine triggers in children are similar to those in adults, but common ones in children are anxiety and fear, and eating ice cream.

Outlook in Children. Migraine in children is disabling, as it is in adults, and they tend to lose more school days than other children. Children with frequent headaches may also be at higher risk for headaches in adulthood and also for other physical and psychiatric problems. However, some children who have migraine eventually stop having attacks when they reach adulthood, or have less severe types of headaches.

Treatments in Children. Most children with migraines may need only mild pain relievers and home remedies (such as ginger tea) to treat their headaches. The American Academy of Neurology’s 2004 practice guidelines for children and adolescents recommend the following drug treatments:

For children age 6 years and older, ibuprofen (Advil) is recommended. Acetaminophen (Tylenol) may also be effective. Acetaminophen works faster than ibuprofen, but the effects of ibuprofen last longer.
For adolescents age 12 years and older, sumaptriptan (Imitrex) nasal spray is recommended.

Preventive Measures in Children. Non-medication methods, including biofeedback and muscle relaxation techniques may be helpful. In one study of children with migraines and poor sleep habits, who were taught how to sleep better instructions without using medications had significantly fewer migraine attacks.

If these methods fail, then preventive drugs may be used, although evidence is weak on the effectiveness of standard migraine preventive drugs in children.

If medication overuse causes rebound migraines develop, the patients cannot recover without stopping the drugs. (If caffeine is the culprit, a person may need only to reduce coffee or tea drinking to a reasonable level, not necessarily stop drinking it altogether.) The patient can usually stop abruptly or gradually. The patient should expect the following:

Most headache drugs can be stopped abruptly, but the patient should talk to their doctor first. Certain non-headache medications, such as anti-anxiety drugs or beta-blockers, require gradual withdrawal.
If the patient chooses to taper off standard headache medications, withdrawal should be completed within three days.
The patient may take other pain medicines during the first days. Examples of drugs that may be used include dihydroergotamine (with or without metoclopramide), NSAIDs (in mild cases), corticosteroids, or valproate.
The patient must expect their headache to get worse after they stop taking their medications, no matter which method they use. Most people feel better within 2 weeks, although headache symptoms can persist up to 16 weeks (and in rare cases even longer).
If the symptoms do not respond to treatment and cause severe nausea and vomiting, the patient may need to be hospitalized.

On the encouraging side, some patients experience dramatic long-term relief from all headaches afterward, and one study reported that 82% of patients significantly improved 4 months after medication withdrawal.

Medications Used for Treatment

Many different medications are used to treat migraines. However, the Food and Drug Administration (FDA) has specifically approved only the following types of drugs for migraine treatment:

Non-prescription drugs: Excedrin Migraine, Advil Migraine, Motrin Migraine Pain
Prescription drugs: Triptans and ergotamine

Other types of drugs, including opioids and barbiturates, are sometimes prescribed off-label for migraine treatment. Opioids and barbiturates have not been approved by the FDA for migraine relief, and they can be addictive.

All FDA-approved migraine treatments are approved only for adults. No migraine products have officially been approved for use in children.

Some patients with mild migraines respond well to over-the-counter (OTC) painkillers, particularly if they take the medicine at the very first sign of an attack.

The Food and Drug Administration has approved three OTC (nonprescription) products to treat migraine. Excedrin Migraine (a combination of aspirin, acetaminophen, and caffeine) was the first such medication approved for the temporary relieve of migraine and its symptoms. Studies have reported significant relief in nearly 70% of patients. It may also help menstrual migraines. Advil Migraine and Motrin Migraine Pain, both containing ibuprofen, are also approved to treat migraine headache.

Cooling Pads. Cooling pads may help during an attack. Some products (Migraine Ice, TheraPatch Headache Cool Gel) use a pad containing a gel that cools the skin for up to 4 hours and can be placed on the forehead, temple, or back of the neck.

Non-steroidal anti-inflammatory drugs (NSAIDs) include aspirin, ibuprofen, and naproxen. They were among the first types of drugs tried to treat mild-to-moderate migraines. Aspirin, ibuprofen (Advil, Motrin), and naproxen (Anaprox, Aleve) are all available without prescription. Naproxen may have specific benefits for migraine. A 2007 study indicated that a combination of naproxen and sumatriptan provides better migraine pain relief than either drug alone.

Other types of NSAIDs are available only by prescription. Some studies indicate that the NSAID combination diclofenac-potassium (Cataflam) may work faster than the migraine drug sumatriptan (Imitrex) and help reduce nausea. The combination is not appropriate for people allergic to aspirin or at risk for bleeding.

Injectable NSAIDs, particularly ketorolac (Toradol), may be very effective for severe and persistent migraines. A 2003 study found that intravenous ketorolac provided greater pain relief than nasal sumatriptan (Imitrex). A 2005 study presented at the annual meeting of the American Headache Society reported that intravenous ketorolac was more effective than opioid drugs for late-stage treatment of severe migraine attacks.

COX-2s are a class of prescription drugs that have the anti-inflammatory effects of NSAIDs, but do not upset most people's stomachs. However, most of these drugs have been withdrawn from the U.S. market due to increased risk for heart attack and stroke. Celecoxib (Celebrex) is the only available COX-2, and it has a strong warning label alerting users of the potential for heart attack, stroke, and serious gastrointestinal problems. (The warning is the same one the Food and Drug Administration recommended for the labels of prescription NSAIDs in 2005.)

NSAID Side Effects. High dosages and long-term use of NSAIDs can increase the risk for heart problems, kidney problems, and stomach bleeding. In April 2005, the FDA asked drug manufacturers of prescription NSAIDs to include with their products the same boxed warning used for the COX-2 inhibitor celecoxib (Celebrex). This boxed warning emphasizes an increased risk for cardiovascular events and gastrointestinal bleeding in people taking these drugs. The FDA also requested manufacturers of over-the-counter NSAIDs to revise their labels to include more specific language concerning potential cardiovascular and gastrointestinal risks. Due to its proven heart benefits, aspirin was excluded from these labeling revisions.

Triptans (also referred to as serotonin agonists) were the first drugs specifically developed for use against migraine. They are the most important migraine drugs currently available. They help maintain serotonin levels in the brain, and so specifically target one of the major components in the migraine process.

Triptans are recommended as first-line drugs for adult patients with moderate-to-severe migraines when NSAIDs are not effective. Triptans have the following benefits:

They are effective for most patients with migraine, as well as patients with combination tension and migraine headaches.
They do not have the sedative effect of other migraine drugs.
Withdrawal after overuse appears to be shorter and less severe than with other migraine medications

Sumatriptan. Sumatriptan (Imitrex) has the longest track record and is the most studied of all triptans. It is available as a fast-dissolving pill, nasal spray, or injection. Injected sumatriptan works the fastest of all the triptans and is the most effective, but it can cause pain at the injection site. The nasal spray form bypasses the stomach and is absorbed more quickly than the oral form. Some patients report relief as soon as 15 minutes after administration. The spray tends to work less well when a person has nasal congestion from cold or allergy. It may also leave a bad taste. Sumatriptan is effective for many patients, but headache recurs in 20 - 40% of people within 24 hours after taking the drug.

A 2007 study in the Journal of the American Medical Association suggested that a combination of sumatriptan and naproxen works better than either drug alone.

Other Triptans. Newer triptans include almotriptan (Axert), zolmitriptan (Zomig), naratriptan (Amerge), rizatriptan (Maxalt), frovatriptan (Frova), and eletriptan (Relpax). Comparison studies with sumatriptan suggest that some of the newer drugs have fewer side effects and are superior to sumatriptan for providing immediate, sustained, and consistent pain relief. Recurrence rates are also lower. They are also being investigated for prevention under certain circumstances, such as menstrual migraines, but benefits appear limited.

Studies on newer triptans indicate:

Almotriptan is as effective as oral sumatriptan and may have fewer side effects, particularly chest pain, than most other triptans.
Rizatriptan may have the most rapid effects of all oral triptans. Zolmitriptan also has a more rapid effect than sumatriptan (although there appears to be no significant difference in adverse effects). Both rizatriptan and zolmitriptan are also available as rapidly dissolving wafers.
Eleptriptan is also very rapidly effective at high doses, but at those levels may have significant adverse effects. (To date, it does not seem to have any advantages over other triptans in head-to-head comparisons.)
Naratriptan and frovatriptan have a delayed response but long duration, few side effects, and lower risk for recurrence than with sumatriptan. Some evidence suggests that they may have specific benefits for stopping prolonged migraines and may even play a role in prevention.
Frovatriptan: A large study of more than 500 women with an average 12-year history of menstrual migraines examined the use of frovatriptan for the short-term prevention of such headaches. Researchers found that the migraines disappeared in over half of the women on the higher dose (5 mg) of frovatriptan.
Zolmitriptan (Zomig): Several studies indicate that zomitriptan nasal spray may be safe and effective for adolescents. In one study, zolmitriptan relieved pain within 2 hours for nearly half of the children (aged 12 - 17 years) enrolled in the trial. Zolmitriptan nasal spray is approved only for adults.

Side Effects. Many of the newer triptans may have fewer severe side effects than sumatriptan. Side effects of most triptans, however, can include:

Tingling and numbness in the toes
Sensations of warmth
Discomfort in the ear, nose, and throat
Nausea
Drowsiness
Dizziness
Muscle weakness
Heaviness, pain, or both in the chest. (About 40% of patients taking sumatriptan experience these symptoms, and they are major factors in discontinuing the drug. Newer drugs, such as almotriptan, produce fewer chest symptoms.)
Rapid heart rate

Complications of Triptans. The following are potentially serious problems.

Complications of heart and circulation. Triptans narrow (constrict) blood vessels. Because of this effect, spasms in the blood vessels may occur and cause serious side effects, including stroke and heart attack. Such events are rare, but patients with an existing history or risk factors for these conditions should generally avoid triptans.
Serotonin syndrome. Serotonin syndrome is a life-threatening condition that occurs from an excess of the brain chemical serotonin. Triptan drugs used to treat migraine, as well as certain types of antidepressant medications, can increase serotonin levels. These antidepressant drugs include serotonin reuptake inhibitors (SSRIs) -- such as fluoxetine (Prozac), paroxetine (Paxil), and sertraline (Zoloft) -- and selective serotonin/norepinephrine reuptake inhibitors (SNRIs), such as duloxetine (Cymbalta) and venlafaxine (Effexor). It is very important that patients not combine a triptan drug with a SSRI or SNRI drug. Serotonin syndrome is most likely to occur when starting or increasing the dose of a triptan or antidepressant drug. Symptoms include restlessness, hallucinations, rapid heartbeat, tremors, increased body temperature, diarrhea, nausea, and vomiting. You should seek immediate medical care if you have these symptoms.

The following people should avoid triptans or take them with caution and only with the advisement of a doctor:

Anyone with a history or any risk factors for stroke, uncontrolled diabetes, high blood pressure, or heart disease.
People taking antidepressants that increase serotonin levels.
Children and adolescents. They may be safe, but controlled studies are needed to confirm this. (Triptans should not, in any case, be the first-line treatment for children.)
People with basilar or hemiplegic migraines. (Triptans are not indicated for these migraineurs.)
There is no evidence to date of any higher risk for birth defects in pregnant women who take triptans. Still, women should be cautious about taking any medications during pregnancy and discuss any possible adverse effects with their doctors.

Drugs containing ergotamine (commonly called ergots) constrict smooth muscles, including those in blood vessels, and are useful for migraine. They were the first anti-migraine drugs available. Ergotamine is available by prescription in the following preparations:

Dihydroergotamine (DHE) is an ergot derivative. It is administered as a nasal spray form (Migranal) or by injection, which can be performed at home.
Ergotamine is available tablets taken by mouth, tablets taken under the tongue (sublingual), and rectal suppositories. Some of the tablet forms of ergotamine contain caffeine.

Ergotamine’s role since the introduction of triptans is now less certain. Only the rectal forms of ergotamine are superior to rectal triptans. Injected, oral, and nasal-spray forms are all inferior to the triptans. Ergotamine may still be helpful for patients with status migrainous or those with frequent recurring headaches.

Side Effects. Side effects of ergotamine include:

Nausea
Dizziness
Tingling sensations
Muscle cramps
Chest or abdominal pain

The following are potentially serious problems:

Toxicity. Ergotamine is toxic at high levels.
Adverse effects on blood vessels. Ergot can cause persistent blood vessel contractions, which may pose a danger for people with heart disease or risk factors for heart attack or stroke.

Internal scarring (fibrosis). Scarring can occur in the areas around the lungs, heart, or kidneys. It is often reversible if the drug is stopped.

The following patients should avoid ergots:

Pregnant women. Ergots can cause miscarriage.
People over age 60.
Patients with serious, chronic health problems, particularly those of the heart and circulation.

Ergotamine can interact with other medications, such as antifungal drugs and some antibiotics. All ergotamine products approved by the Food and Drug Administration (FDA) contain a "black box" warning in the prescription label explaining these drug interactions. In 2007, the FDA pulled 15 unapproved older ergotamine products off the market, in part because they lacked this warning label. The five FDA-approved ergotamine products that remain on the market are:

Migergot suppository (marketed by G and W Labs)
Ergotamine Tartrate and Caffeine tablets (marketed by Mikart and West Ward)
Cafergot tablets (marketed by Sandoz)
Ergomar sublingual tablets (marketed by Rosedale Therapeutics)

Nasal drops containing lidocaine, a local anesthetic, can provide effective and quick pain relief within 15 minutes for many migraine sufferers. However, lidocaine has certain downsides:

It is rather difficult to administer. Patients must be lying down with their head dangling.
The headache often relapses in an hour, and other drugs must then be used.
Side effects include unpleasant taste, burning sensation, and facial numbness.

However, the drug does not cause drowsiness or heart rhythm disturbances as some other migraine treatments do. It should not be used for any other form of headache.

If the pain is very severe and does respond to other drugs, doctors may try painkillers containing opioids. Opioid drugs include morphine, codeine, meperidine (Demerol), and oxycodone (Oxycontin)]. Butorphanol is an opioid in nasal spray form that may be useful as a rescue treatment when others fail.

Opioids are not approved for migraine treatment and should not be used as first-line therapy. Nevertheless, many opioid products are prescribed to patients with migraine, sometimes with dangerous results. In 2007, following reports of several drug-related deaths, the Food and Drug Administration warned that the cancer pain pill fentanyl (Fentora) should not be used to treat patients with migraine or others conditions for which the drug is not specifically approved.

Side Effects. Side effects for all opioids include drowsiness, impaired judgment, nausea, and constipation. There is a risk for addiction, and these drugs can become ineffective with long-term use for chronic migraines. Doctors should not prescribe opioids to patients at risk for drug abuse, including those with personality or psychiatric disorders.

Metoclopramide (Reglan) is used in combinations with other drugs to treat the nausea and vomiting that occurs with other drugs and with migraine itself. Metoclopramide and other anti-nausea drugs, such as domperidone (Motilium), may help the intestine better absorb migraine medications.

New drugs in clinical trials include tonabersat (a gap junction blocker), trexima (a combination triptan and non-steroidal anti-inflammatory drug), GW274150 (a nitric oxide synthase inhibitor), and MK-0974 (a calcitonin gene-related peptide antagonist). Researchers are also investigating a nasal spray containing capsaicin, the chemical found in cayenne peppers.

Prevention

There are several ways to prevent migraine attacks. You should try a healthy diet, the right amount of sleep, and non-drug approaches, such as biofeedback, first for prevention.

Behavioral techniques that reduce stress and empower the patient may help some people with migraines. Studies report between 35 - 50% reduction in migraine and tension-type headaches with these approaches. They generally include:

Biofeedback therapy
Cognitive-behavioral therapy
Relaxation techniques

Behavioral methods may help counteract the tendency for muscle contraction and uneven blood flow associated with some headaches. They may be particularly beneficial for children, adolescents, and pregnant and nursing women, and anyone who cannot take most migraine medications.

Biofeedback. Studies have demonstrated some effectiveness from biofeedback for migraine headaches. Biofeedback training teaches the patient to monitor and modify physical responses, such as muscle tension, using special instruments for feedback.

Cognitive Behavioral Therapy. Behavioral therapy may be useful alone but is particularly beneficial for patients who are on preventive drug treatments. It typically uses the headache diary to track activities and headaches. The patient then works with the therapist to change or add behaviors or medications that will reduce the frequency and severity of attacks.

Alternative non-drug therapies used for headache management and prevention include hypnosis, meditation, visualization and guided imagery, acupuncture, acupressure, yoga, and other relaxation exercises. There is no clear evidence that any of these techniques have specific value for migraines.

Some studies report the following:

Acupuncture. Acupuncture is a Chinese medicine technique that uses thin needles to stimulate specific points aligned with energy pathways in the body. Studies have showed mixed results on the benefits of acupuncture for migraine. A 2005 study published in the Journal of the American Medical Association reported that acupuncture was no more effective than sham acupuncture (needles placed at non-acupuncture points) in preventing migraines. More than 300 people were enrolled in this randomized trial. A 2006 study of 960 people, published in Lancet Neurology, found that real acupuncture, sham acupuncture, and standard drug treatment were all equally effective in preventing migraine attacks.
Relaxation Techniques. Muscle relaxation techniques may be helpful. One study reported that relaxation treatments appeared to help adolescents with migraine but not tension headaches.

Hormonal drugs, such as oral contraceptives or hormone replacement therapy, have a mixed effect on women with migraines. Oral contraceptives have been associated with worse headaches in 18 - 50% of women and have also been linked to a higher risk for stroke in women with classic migraines (with auras). Young women should avoid or stop oral contraception if they have classic migraines, migraines that worsen or change character after oral contraceptives , if they have close relatives with stroke or heart disease, or if they smoke.

Some evidence suggests, however, that oral contraceptives may help prevent true menstrual migraines (which do not have auras). In such cases, their benefits may outweigh the low risk of a serious adverse event. Keeping a migraine record for at least three menstrual cycles can help confirm whether a woman actually has a true menstrual migraine.

Making a few minor changes in your lifestyle can make your migraines more bearable. Improving sleep habits is important for everyone, and especially those with headaches. What you eat also has a huge impact on migraines, so dietary changes can be extremely beneficial, too.

Avoiding Food Triggers. Avoiding foods that trigger migraine is an important preventive measure. Common food triggers include monosodium glutamate (MSG), processed lunch meats that contain nitrates, dried fruits that contain sulfites, aged cheese, alcohol and red wine, chocolate, and caffeine. However, people’s responses to triggers differ. Keeping a headache diary that tracks diet and headache onset can help identify individual food triggers.

Healthy Diet. One study indicated that a diet low in fat and high in complex carbohydrates may significantly reduce the frequency, severity, and duration of migraine headaches. Such a diet is healthy in general, in any case.

Eating Regularly. Eating regularly is important to prevent low blood sugar. People with migraines who fast periodically for religious reasons might consider taking preventive medications.

Fish Oil. Some studies suggest that omega-3 fatty acids, which are found in fish oil, have anti-inflammatory and nerve protecting actions. These fatty acids can be found in oily fish, such as salmon, mackerel, or sardines. They can also be obtained in supplements of specific omega-3 compounds (DHA-EPA).

Exercise is certainly helpful for relieving stress. An analysis of several studies reported that aerobic exercise in particular might help prevent migraines. It is important, however, to warm up gradually before beginning a session, since sudden, vigorous exercise might actually precipitate or aggravate a migraine attack.

Manufacturers of herbal remedies and dietary supplements do not need Food and Drug Administration 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 several reported cases of serious and even lethal side effects from herbal products. Patients should always check with their doctors before using any herbal remedies or dietary supplements.

Riboflavin (Vitamin B2). There is reasonable evidence on the benefits of vitamin B2 for migraine sufferers. In one study, patients who took 400 mg of vitamin B2 (riboflavin) reduced their migraine attacks by half, although the vitamin had no effect on the severity or duration of migraines that did occur. In another study, it helped increase the effectiveness of beta-blockers, drugs used to prevent migraines in some people. Vitamin B2 is generally safe, although some people taking high doses develop diarrhea.

Magnesium Supplements. Studies have reported a higher rate of magnesium deficiencies in some patients with migraine, such as those with menstrual migraines. Magnesium helps relax blood vessels. Some patients report relief from supplements.

Feverfew. Feverfew is the most studied herbal remedy for headaches and is effective in some cases. However, like all effective headache remedies, overuse can cause a rebound effect.

Ginger. In general, herbal medicines should never be used by children or pregnant or nursing women without medical counsel. One exception may be ginger, which has no side effects and can be eaten in powder or fresh form, as long as quantities are not excessive. Some people have reported less pain and frequency of migraines while taking ginger, and children can take it without danger.

Medications Used for Prevention

The Food and Drug Administration has approved four drugs for prevention of migraine:

Propanolol (Inderal)
Timolol (Blacadrene)
Divalproex sodium (Depakote)
Topiramate (Topamax)

Propanolol and timolol are beta-blocker drugs. Divalproex and topiramate are anti-seizure drugs. Many other drugs are also being used or investigated for preventing migraines.

Beta-blockers are usually prescribed to reduce high blood pressure. Some beta-blockers, however, are also useful in reducing the frequency of migraine attacks and their severity when they occur. Propranolol (Inderal) and timolol (Blocadren) have been approved specifically for prevention of migraine. Metoprolol (Toprol), atenolol (Tenormin), and nadolol (Corgard) are also being studied for migraine prevention.

Side Effects. Side effects may include:

Fatigue and lethargy are common.
Some people experience vivid dreams and nightmares, depression, and memory loss.
Dizziness and lightheadedness may occur upon standing.
Exercise capacity may be reduced.
Other side effects may include cold extremities, asthma, decreased heart function, gastrointestinal problems, and sexual dysfunction.

If side effects occur, the patient should call a doctor, but it is extremely important not to stop the drug abruptly. Some evidence suggests that people with migraines who have had a stroke should avoid beta-blockers.

Anti-seizure drugs, also called anti-epileptic drugs or anticonvulsants, affect the neurotransmitter gamma aminobutyric acid (GABA), which helps prevent nerve cells from over-firing. GABA may also have a role in migraines. These drugs are commonly used for epilepsy and bipolar disease. Anti-seizure drugs are more expensive than other drugs. They also have significant side effects. Divalproex sodium (Depakote) and topiramate (Topamax) are the only anti-seizure drugs that are approved for migraine prevention. However, if patients do not respond to either of these drugs, doctors may try other types of anti-seizure medications.

Divalproex Sodium (Depakote). Divalproex sodium (Depakote) was first approved in 1996 for migraine prevention. A once-a-day formulation of divalproex (Depakote ER) was approved in 2000. Doctors sometimes prescribe a similar drug, valproate (Depakene). Pregnant patients should not use these drugs, as they may cause birth defects.

Topiramate (Topamax). In 2004, the Food and Drug Administration approved topiramate for prevention of migraines in adults. Studies from 2006 indicated that the drug works well when used on a long-term basis. Patients in these studies experienced significantly fewer migraines for up to 14 months. Topiramate’s most common side effect is a tingling sensation in the arms and legs. Weight loss is also a side effect. In clinical trials, patients lost an average of 3.8% of their body weight.

Other Anti-Seizure Drugs Under Investigation. Researchers are studying other types of anti-seizure drugs for migraine prevention. These include levetiracetam (Keppra), gabapentin (Neurontin), pregabalin (Lyrica), zonisamide (Zonegran), tiagabine (Gabitril), and the investigational drug lacosamide (LCM).

Side Effects. Anti-seizure medication's side effects vary by drug but may include:

Nausea and vomiting
Diarrhea
Cramps
Hair loss
Dizziness
Sleepiness
Blurred vision
Weight gain
Valproate and divalproex can cause serious side effects of inflammation of the pancreas (pancreatitis) and damage to the liver

Amitriptyline (Elavil, Endep), a tricyclic antidepressant drug, has been used for many years as a first-line treatment for migraine prevention. It may work best for patients who also have depression or insomnia. Tricyclics can have significant side effects, including disturbances in heart rhythms, and can be fatal in overdose. Although other tricyclic antidepressants may have fewer side effects than amitritpyline, they do not appear to be particularly effective for migraine prevention.

Researchers have investigated newer types of antidepressants, including serotonin-reuptake inhibitors(SSRIs), such as fluoxetine (Prozac). However, studies to date do not indicate that SSRIs are helpful for migraine prevention.

Muscle Relaxants. Botulinum toxin A (Botox) injection, a common wrinkle treatment, causes small muscles to relax. This approach is now being used with some success for treating disorders that involve over-excited muscle activity, including myofascial pain syndrome and migraine. One study reported complete migraine relief in more than half of patients being tested and improvement of more than 50% in another 35% of patients. Relief lasted 3 - 4 months with no adverse effects. A study presented at the 2005 meeting of the American Headache Society reported that patients who regularly received Botox injections every 3 months reduced both the frequency of migraine attacks and their reliance on pain medications

Angiotensin Converting Enzyme Inhibitors. Commonly used for treating high blood pressure, angiotensin converting enzyme (ACE) inhibitors block the production of the protein angiotensin, which constricts blood vessels and may be involved in migraine. Studies using the ACE inhibitor lisinopril (Prinivil, Zestril) are reporting significant reduction in migraine attacks.

Angiotensin-Receptor Blockers. Angiotensin-receptor blockers (ARBs) have actions similar to ACE inhibitors, but may have fewer side effects. In one study, patients who took the ARB candesartan (Atacand) had significantly fewer headaches compared to patients who received placebo.

Neurostimulation Devices. Researchers are investigating a transcranial magnetic stimulation (TMS) device to help stop migraines before they occur. The hair dryer-size device is held to the back of the head and delivers quick magnetic pulses. The device is used when a patient experiences the first signs of a migraine. Other types of nerve stimulation devices are also under investigation.

Inhalation Devices. These devices use heat to vaporize a drug so that it can be inhaled into the lungs. Clinical trials are currently testing this device with procholorperazine (Compazine), a tranquilizer drug that is used to treat nausea and vomiting.

Nasal Devices. New types of nasal sprays and powders are being researched. Some of them use capsaicin, the chemical found in cayenne peppers, to help relieve pain.

Skin Patches. The Actyve transdermal patch uses a small battery-powered system to deliver a triptan drug through the skin.

Drugs. New drugs in development include tonabersat (gap junction blocker), trexima (combination triptan and non-steroidal anti-inflammatory drug), and GW274150 (nitric oxide synthase inhibitor).
