Chronicity and relapse in geriatric depression.

Overview

Recent advances in the methodology of longitudinal investigations have permitted the identification of predictors of chronicity and relapse of depression. However, findings from mixed-age populations may not be directly applicable to geriatric depression. The effects of medical illness, cognitive dysfunction, and neuroradiological abnormalities on the outcome of geriatric depression merit further evaluation. Late-onset depression requires special attention, since medical and neurological disorders may be particularly important factors in these cases.
