Brief Summary

Patients with obsessive-compulsive disorder (OCD) experience a wide array of different types of obsessions and compulsions. However, current treatments for OCD employ a "one size fits all" approach and are used for all patients regardless of symptom type. In this project, the investigators propose to investigate whether a novel method of transcranial magnetic stimulation specifically reduces contamination/washing symptoms - one of the most common types of OCD.
