Abstract

Introduction

Studies comparing the antidepressant effects of electroconvulsive therapy (ECT) and repetitive transcranial magnetic stimulation (rTMS) have reported mixed results. This study compared the efficacy of rTMS and ECT in adult patients with refractory major depressive disorder (MDD).

Methods

This randomized, ECT-controlled, parallel-group clinical trial analyzed the antidepressant effects of ECT and rTMS in 73 patients with MDD diagnosed according to Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria. The Beck Depression Inventory and Hamilton Depression Rating Scale were used to measure depression.

Results

Both ECT and rTMS significantly improved depression and suicidal behavior scores. However, ECT reduced depression and suicidal behavior scores more than rTMS. There were no significant adverse effects in the rTMS group.

Discussion

Both ECT and rTMS improved MDD in the short term, but the antidepressant efficacy of ECT was greater than rTMS. Moreover, ECT led to greater reductions in suicidal behavior than rTMS. Until strong evidence for the safety and efficacy of rTMS is available, further studies are needed to compare ECT and rTMS in terms of the long-term relapse rate and quality of life.
