• A meta-analysis of 25 RCTs indicates that repetitive transcranial magnetic stimulation (rTMS) has a moderate therapeutic effect on obsessive-compulsive disorder (OCD) severity.
• rTMS demonstrates a significant treatment response compared to sham conditions, with an average response rate of 39.5% versus 8.8%, respectively.
• Greater improvement in depression severity, longer TMS sessions, and fewer TMS sessions are associated with greater improvement in OCD severity.
• Clinicians should consider rTMS for OCD, particularly in patients who have not responded to other treatments or those with comorbid depression.
