What causes bipolar II disorder?

As with most other mental disorders, there is no single cause for bipolar II disorder. For example, it is not directly passed from one generation to another genetically. Rather, it is the result of a complex group of genetic, psychological, and environmental factors. Genetically, bipolar disorders and schizophrenia have much in common, in that the two disorders share a number of the same risk genes. However, both illnesses also have some genetic factors that are unique. Stress has been found to be a significant contributor to the development of most mental illnesses, including bipolar disorder.

As is true with virtually any mental-health diagnosis, there is no one test that definitively indicates that someone has bipolar II disorder. Therefore, health-care practitioners diagnose this disorder by gathering comprehensive medical, family, and mental-health information. The practitioner will also either perform a physical examination or request that the individual's primary-care doctor perform one. Medical testing will usually include lab tests to evaluate the person's general health and to explore whether or not the individual has a medical condition that might have mental-health symptoms.
