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.

Primary Outcome Measures:
  • Depression [ Time Frame: 8 weeks ]
    The primary objective of this study is to provide hypothesis generation data that may later be tested through a placebo controlled trial. Accordingly, we will examine whether minocycline alone or as an augmenting agent of antidepressants or mood stabilizers reduces depressive symptoms and disability and promotes remission of major depression

Estimated Enrollment: 50
Study Start Date: March 2012
Estimated Study Completion Date: April 2015
Estimated Primary Completion Date: April 2015 (Final data collection date for primary outcome measure)
