    IntroductionMagnetic seizure therapy (MST) is a new convulsive therapy that is as effective as traditional electroconvulsive therapy (ECT) in treating depression but with fewer cognitive side effects. The aim of this study was to compare the efficacy and cognitive effects between MST (100 Hz applied over the vertex) and bifrontal ECT for treating patients with depressive episodes.MethodsForty-five patients with depressive episodes were enrolled, with 18 receiving MST and 27 receiving ECT. MST was administered over the vertex with 100 Hz frequency. Treatment consisted of six sessions. The 17-item Hamilton Rating Scale for Depression (HAMD-17) was used to assess the severity of depression. The Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) was used to assess cognition. Assessments were performed at baseline and after the third and sixth treatment sessions.ResultsBoth MST and ECT improved the patients' depressive symptoms significantly, yet no significant difference was found between the two groups (p > .05). The response rates and remission rates of MST and ECT were 72.2% versus 81.5% and 61.1% versus 63.0%, respectively. The MST group showed significant improvements in immediate memory (p < .001), delayed memory (p = .002), and attention (p < .001) than ECT. The recovery times for consciousness (p < .001), spontaneous breathing (p < .001), and orientation (p < .001) were shorter in MST group than ECT group. RBANS improvements were negatively correlated with the recovery time for orientation (r = .561, p < .001).ConclusionMagnetic seizure therapy showed similar efficacy to bifrontal ECT for treating depressive episodes. While MST may be an effective alternative to ECT, larger randomized trials are needed.© 2020 The Authors. Brain and Behavior published by Wiley Periodicals LLC.
