Recovery and relapse in geriatric depression after treatment with antidepressants and ECT in a medical-psychiatric population.

The objective of this naturalistic, longitudinal treatment outcome study was to determine relapse rates in geriatric depression following treatment with antidepressants and electroconvulsive therapy in a medical-psychiatric population. Thirty-nine elderly patients (average age 71 years) with unipolar major depression were treated with either antidepressants (AD) or, if resistant to AD treatment, ECT followed by maintenance antidepressants. Patients were monitored over 18 months, and relapse rates were closely determined using the Longitudinal Interval Follow-up Evaluation (LIFE) and the 21-item Hamilton Depression Rating Scale. Although 90% of patients recovered from their index episode of depression, relapse rates were approximately 29%. These results indicate that in spite of high chances of recovery from geriatric depression, intensive psychopharmacologic and psychotherapeutic strategies are needed to decrease relapse rates in geriatric depression.
