Individuals age 16 and older who have bipolar disorder or schizoaffective disorder, bipolar type, are invited to participate in a genetic study at the University of Pennsylvania. (Bipolar disorder is also called manic-depressive illness.)

The study is led by Dr. Wade Berrettini, director of the Center for Neurobiology and Behavior, and is part of a national project funded by the National Institute of Mental Health. The project's goal is to identify the genes that predispose individuals to develop bipolar disorder. This study may ultimately lead to earlier detection and improved treatment for this disorder.

Participants fill out several confidential questionnaires, complete a confidential interview, and have a small blood sample drawn at our expense. Participants are reimbursed $100 for their time.

No treatment or medications are involved in this study. It is not necessary to travel to the University to participate.
