Electroconvulsive therapy (ECT) is an effective treatment of mania. Ultrabrief ECT is a novel modality that is associated with fewer cognitive adverse effects than the standard pulse width brief pulse ECT. It has been well studied in depression. However, its use in mania is not yet known. Following a retrospective chart view, we report a small sample of patients who had Right Unilateral Ultrabrief ECT (RUB-ECT) for mania. Eleven RUB-ECTs were identified for 9 patients; 72.8% remission rate was observed with RUB-ECT. Two patients required switch into bitemporal ECT in view of minimal clinical response and 1 patient to right unilateral brief pulse ECT because of poor seizure parameters. All patients achieved remission eventually. The possible mechanisms of ECT in mania and clinical implications of ultrabrief ECT are discussed.
