Individuals are also more likely to develop bipolar disorder if they have another mental health condition, such as depression or schizophrenia. After initial enthusiasm supported by strong genetic linkage signals, it was quickly discovered that these results could not be replicated (14). This disorder most often appears in late adolescence or early adulthood, although symptoms can begin at any time of life. The known inheritance pattern for bipolar disorder is not as well known as other disorders, but there does seem to be a genetic component and environment component that interplay with each other (Saddock & Saddock: Synopsis of Psychiatry) TIPS AND WISDOM.
