Study Summary
The purpose of this study is to use brain imaging technology to examine the role of certain brain receptors and the nervous system chemical acetylcholine in major depression. The cholinergic system involves the regulation of neurotransmitters and the brain receptors to which they bind. Evidence suggests that the cholinergic system may play a role in the development of depression. Acetylcholine is a neurotransmitter that binds to certain brain receptors called muscarinic cholinergic receptors. Cholinomimetic drugs (drugs that stimulate the cholinergic system) often exacerbate depressive symptoms in people with mood disorders and in healthy individuals. This increase in depressive symptoms may be caused by stimulation of muscarinic acetylcholine receptors (mAChRs), but further study is needed to confirm this. This study will use positron emission tomography (PET) and magnetic resonance imaging (MRI) to study the function of mAChRs in individuals with depression. Participants in this study will undergo a physical examination, psychiatric interviews, neuropsychological tests, PET and MRI scans, and rating scales of depression, anxiety, and negative thinking symptoms. Questions about behavior and functioning will be asked and blood samples will be collected for genetic analysis.
