OBJECTIVE: To determine the relative efficacy of electroconvulsive therapy (ECT) in the treatment of bipolar (BP) and unipolar (UP) depressive illness and clarify its role in BP depression. METHOD: Patients referred for ECT with both UP and BP depressions. [classified by Structured Clinical Interview for DSM (SCID-I) criteria for history of mania] were included in a multi-site collaborative, double-masked, randomized controlled trial of three electrode placements - right unilateral, bifrontal or bitemporal - in a permutated block randomization scheme. RESULTS: Of 220 patients, 170 patients (77.3%) were classified as UP and 50 (22.7%) as BP depression in the intent-to-treat sample. The remission and response rates and numbers of ECT for both groups were equivalent. CONCLUSION: Both UP and BP depressions remit with ECT. Polarity is not a factor in the response rate. In this sample ECT did not precipitate mania in depressed patients. Treatment algorithms for UP and BP depression warrant re-evaluation.
