Official title
Role of the Metabotropic Glutamate Receptor Subtype 5 in Circadian Rhythm Misalignment and Depression: Implications for Treatment
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
16.2 million American adults are affected by depression each year. The investigators are studying the relationship between sleep/wake cycle and depression. Mounting evidence suggests that abnormalities in circadian rhythms (biological changes that happen over the course of the day or night) are related to mood disorders. This may explain why people with depression frequently suffer with sleeping problems. The purpose of this study is to understand how circadian (sleep/wake) rhythms may be affected in depression and the best way to improve depression caused in this way. This will be performed by comparing circadian (sleep/wake) rhythms in people with and without depression. The study involves being kept awake for one night. For depressed individuals, this technique will likely result in a brief (\<1 day) improvement in depression. Following this study, participants with depression will be offered antidepressant medication at no cost. During the study, the investigators use brain scans to learn more about brain chemistry in health and depression.
