When it comes to mental illnesses such as anxiety and depression, diagnosis is not at all an exact science. A patient tells a doctor or psychiatrist their physical and emotional symptoms, and then the doctor uses his or her judgment to make a diagnosis.
Some patients may end up getting diagnosed for an illness that they don't necessarily have, and on the other hand, people who have certain illnesses may not even know it. This kind of diagnosis also makes it hard to determine the severity of the condition.
Well now scientists have discovered 10 genes in the blood that can predict a person's mood, which could help determine if a person has bipolar disorder. This blood test could hit the market in less than five years. It would be a huge breakthrough in the world of psychiatry. Not only could this blood test help to determine whether or not a patient has a mental illness, but it could also help ensure that the patient is getting the right medication to treat it.
This test could also bring up some controversy though. Could a blood test that diagnoses mental illness be mandatory to screen people before they buy guns, enroll in the military, or start a new job? What's your opinion on a blood test for mental illness? Do you think it's a brilliant idea, or could it pose more problems instead?
