Treatment of Obsessive-Compulsive Disorder (OCD) with Transcranial Magnetic Stimulation (TMS)

This study is a research trial of an outpatient, non-medication, non-invasive investigational treatment called Transcranial Magnetic Stimulation (TMS). TMS applies a magnetic field to the brain for a brief period of time. TMS is a procedure that involves 30 minute-long daily sessions every weekday for a series of weeks. We are testing whether TMS can treat obsessive-compulsive disorder (OCD).

Participants will be randomly assigned to receive either active rTMS or sham (placebo) rTMS. If patients receive sham and/or do not improve, they have the option of receiving real TMS in the second phase of the study. All evaluations and treatment are provided at no cost to the research participant.
