Bifrontal versus bitemporal electroconvulsive therapy in severe manic patients

Objectives: To compare the efficacy and safety of moderate-dose bifrontal (BF) with low-dose bitemporal (BT) electroconvulsive therapy (ECT) in the treatment of patients with severe mania. Methods: In a parallel, double-blind, randomized clinical trial, 28 patients with severe mania admitted to a university hospital were assigned randomly to moderate-dose BF (n = 14) and low-dose BT (n = 14) ECT The primary outcome measures included the Mini-Mental State Examination (MMSE) and the Young Mania Rating Scale (YMRS). Results: All patients received at least 6 sessions of ECT The 2 Groups did not show any difference in their baseline MMSE or YMRS scores (P > 0.05). There was a significant difference between the MMSE scores of the BF compared with the BT group after both the sixth ECT (P < 0.05) and final ECT treatments (P < 0.05). Young Mania Rating Scale scores did not differ between the 2 groups after either the sixth or the last ECT sessions (P > 0.05). Conclusions: Moderate-dose BF ECT was as effective as BT ECT but was associated with fewer cognitive side effects in the treatment of patients with severe mania.
