Primary Investigator

Overview

The purpose of this study is to determine if the study treatment, repetitive transcranial magnetic
stimulation (rTMS), helps improve symptoms of your illness and adjusts communication between
related areas of the brain. rTMS is a non-invasive technique that applies a magnetic field over the scalp
to cause activation within the brain.
