Transcranial Magnetic Stimulation (TMS) and Obsessive Compulsive Disorder (OCD)

Stimulus train of 30 min duration, 1Hz frequency, and 110% of the motor threshold intensity given once a day, 5 days a week, for 4 weeks by Magstim SuperRapid Magnetic Stimulator.

Sham rTMS will be administered using the Magstim Sham coil which contains a mu-metal shield that diverts the majority of the magnetic flux such that a minimal (less than 3%) magnetic field is delivered to the cortex in order to provoke a subjective sensation similar to that obtained with the real stimulation but without inducing significant cortical stimulation.
