• Status: Unknown status
• Trial end date: 2017-07-01
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of the research is to study brain structure, function and chemistry of patients with bipolar disorder who are receiving lithium, an FDA-approved treatment for bipolar mania, in order to better understand who benefits from treatment and why they respond to medications. Studying this may help improve treatment and outcome in patients with bipolar disorder.
