DIAMOND Brain Imaging Study – Young Adults without Bipolar Disorder

STUDY BASICS

Are you 18-30 years old and have not been diagnosed with bipolar disorder? If so, you may be eligible to participate in a research study to help learn more about brain structure and function in people with and without bipolar disorder. Participants must be fluent in English. Compensation provided.

STUDY PURPOSE

Bipolar disorder, also known as manic-depressive disorder, is an illness that causes extreme mood changes from manic episodes of very high energy to extreme lows of depression. Although certain risk factors can make it more likely that a person will develop bipolar disorder, researchers do not fully understand why some people develop the condition and others do not. The purpose of this study is to help researchers learn more about the structure and function of the brain in young people with and without bipolar disorder. Researchers hope their findings will lead to better ways to identify and treat bipolar disorder in the future.

WHAT PARTICIPANTS CAN EXPECT

This study involves an initial screening visit that will last about 3 hours. During the screening visit, participants will have a structured interview about their lifetime psychiatric history, family psychiatric history, and other medical history; an assessment of current symptoms, mood, behaviors, and life; reading, memory, and vision tests; and physical measurements. At the second visit, eligible participants will undergo urine and saliva collection and will have an fMRI scan while performing computer tasks. FMRI scans are not invasive and do not use radiation. Other study procedures include having blood draws and completing questionnaires. Participants will also have four follow-up interviews at 6, 12, 18, and 24 months after the fMRI scan. These interviews will consist of many of the same assessments and questionnaires used at the screening visits but can be completed at home via video call.
