A Systematic Review of the Efficacy of Repetitive Transcranial Magnetic Stimulation Treatment for Women with Postpartum Depression

Abstract

Transcranial Magnetic Stimulation (TMS) has a strong evidence base for the treatment of major depressive disorder (MDD), however, there is minimal research investigating the treatment of depression within the postpartum period. This systematic review aims to systematically examine the efficacy and safety of TMS when treating postpartum depression (PPD). Databases Ovid Medline, PsycINFO, EMBASE and PubMed were searched from inception to May 2021, to identify peer-reviewed papers assessing the administration of TMS for PPD treatment. Data were systematically extracted and evaluated regarding clinical psychiatric outcomes, social-relational outcomes, neuropsychological testing, and side effects. This systematic review included one randomised controlled trial, two open-label studies, two conference papers, and two case studies, providing data on 60 participants. TMS appears well tolerated, with no reported major adverse side effects. While the studies reported a general reduction in PPD symptoms, the poor quality of the evidence available indicates that TMS for PPD is unable to be currently recommended. However, the substantial evidence for TMS in the treatment of MDD and the differential response to antidepressant medication in PPD indicates that further research into TMS for PPD is warranted.
