Study Summary
The purpose of this study is to evaluate the function of certain brain chemicals and receptors in patients with mood disorders. This study will also examine how the stress hormone cortisol affects brain function. Data suggest that serotonin 1A (5-HT1A) receptor function is abnormal in patients with mood disorders, such as major depressive disorder (MDD) and bipolar disorder (BP). However, these data are limited because they are based on small sample sizes. In this study, PET scans will be used to compare 5-HT1A receptor binding potential between mood disorder patients and healthy volunteers. All participants will have an initial medical and psychiatric evaluation. Depression severity, anxiety, negative thinking, level of functioning, intelligence, and cognitive functions will be measured. Urine, saliva, and blood will be collected. Women will have a pregnancy test and tests to determine menstrual phase and time of ovulation. Participants will undergo magnetic resonance imaging (MRI) and PET scans of the brain. Some participants will have other procedures such as a lumbar puncture. Participants with Cushing's disease will undergo imaging as a comparison group.
