Electroconvulsive therapy is equally effective in unipolar and bipolar depression. 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.
