What are the causes of Bipolar Affective Disorder?

There are only theories about what causes Bipolar D/O; however, there does appear to be a genetic-environmental interaction that occurs to "cause" these symptoms. Having blood-related relatives with severe mental health problems (e.g., schizophrenia, severe depression, bipolar d/o) increases the likelihood of some one in your family having Bipolar D/O, but then this disorder only occurs in about 1% of the population. Thus, the genetic component does not appear to be the be all end all of the story. There is some evidence that suggests the combination of a genetic predisposition combined with a high level of parental distress and inconsistency may lead to bipolar, but these are only correlations.

You eat too many NUTS
I don't believe that any thing causes bipolar disorder I think it is a problem that some people are born with. My sister has it and the side affects are one minute some one is on top of the world and the next they are mad or more depressed than ever.It will tear a family up if it is not treated. It is treated with medicine and it truly works.
There is no single cause. "Differences in people's genetic make up can make them more vulnerable to develop bipolar affective disorder. Stressful events, illness or lack of support can trigger individual episodes of illness. "

Please ignore "You eat too many NUTS." That was in extremely bad taste!

Bipolar Disorder is caused my a chemical imbalance in the brain. It is not your fault or the fault of anyone else. It is not caused by what you eat or psychosocial factors (such as who you date or what kind of job you have).

There is strong evidence supporting a genetic linkage with bipolar disorder (as well as unipolar depression).
