is the largest treatment study conducted for bipolar disorder, also known as manic-depressive illness. STEP-BD completed its data collection on September 30, 2005, with a total enrollment of 4361 participants and is no longer enrolling participants. The investigators are now actively working with the extensive STEP-BD database to answer important questions about the course of bipolar disorder and best approaches for treatment and management of this disorder. If you haven’t already participated, please see the link to the STEP-BD Genetics Studies
(on the Public Information page). These studies are still active, and will investigate the genetic basis of bipolar disorder.
If you were a participant in STEP-BD, thank you again for your important contribution to this groundbreaking research. By sharing your experience with bipolar disorder, your treatment response, and your quality of life during treatment, we have learned a substantial amount about the course of this illness, as well as treatment options. We hope to use these data to improve treatment standards for the more than 2 million other Americans with bipolar disorder.
