This is a pilot study to examine the tolerability, safety and early efficacy of two forms of transcranial magnetic stimulation (TMS) for treating adolescents with Obsessive Compulsive Disorder (OCD) who have experienced limited improvements with usual treatments for OCD in adolescents.
The project's primary goal is to examine whether adolescents can complete 3 consecutive weeks of TMS administered 5 days per week, and to describe the type of and how common individual side effects with TMS occur in adolescents with OCD.
Participants will:
* visit the clinic every weekday for 3 weeks (15 days) to receive TMS treatments
* have a brain MRI scan before TMS treatments begins and after finishing all TMS
* complete questionnaires and report changes in behavior and physical symptoms
