BACKGROUND:Bifrontal electrode placement is as efficacious as bitemporal placement during electroconvulsive therapy (ECT) in depression but is associated with fewer cognitive adverse effects. There are no studies comparing these techniques in acute mania. This study compared the short-term efficacy and adverse effects of bifrontal and bitemporal ECT in the treatment of acute mania. METHOD: Thirty-six DSM-IV mania inpatients referred for ECT were recruited for study. They were randomized to receive bifrontal (BFECT; n = 17) or bitemporal (BTECT; n = 19) ECT. None of the subjects were on mood stabilizers during the course of ECT. Severity of mania was measured on the Young Mania Rating Scale (YMRS) before beginning ECT and then on Days 3, 7, 11, 14, and 21 of treatment. Cognitive functions were assessed eight hours after the fifth ECT session using the Mini-Mental Status Examination (MMSE), Paired Associate Learning Test, Complex Figure Test, Verbal Fluency Test (animals and fruits categories), and Trail Making Test, Part A. RESULTS: The subjects in the two groups were comparable on sociodemographic and clinical variables, including severity of mania at baseline. They were also similar in ECT parameters, including seizure threshold and seizure duration. Mean YMRS scores showed faster decline in the BFECT than in the BTECT group. Kaplan-Meier survival analysis showed that a greater proportion of subjects in the BFECT group responded (50% reduction in YMRS score) significantly earlier than in the BTECT group. There were no significant differences between the groups in performance on cognitive function tests. CONCLUSION: In this pilot study, mania patients treated with BFECT responded faster than those treated with BTECT, with comparable cognitive adverse effects. Since ECT is usually prescribed for rapid control of symptoms, BFECT may be preferred over BTECT in the treatment of acute mania.
