Open Treatment of Minocycline in Geriatric Depression

Completed · Not applicable

Conditions studied: Depression

In brief

This research study will examine whether elderly depressed patients whose depressive symptoms do not respond satisfactorily to therapy with a mood stabilizer or antidepressant alone gain any benefit from taking minocycline alone or in addition to their antidepressant or mood stabilizer medication. Minocycline is a commonly used antibiotic medication with anti-inflammatory properties. It is hoped that information gained from this study will help the investigators better understand the role of inflammation in depression, and whether decreasing inflammation will lead to improvement in the symptoms of depression and cognitive function.
