Repetitive Transcranial Magnetic Stimulation (rTMS) in the Treatment of Obsessive Compulsive Disorder

The purpose of study is to examine the efficacy of rTMS over different brain areas, including the bilateral supplement motor Area (SMA), the right dorsal lateral prefrontal cortex (DLPFC) and SMA+DLPFC in the treatment of OCD. 120 OCD patients will be randomized into four groups. Continuous theta burst stimulation (cTBS) stimulation will be performed once a day, five times a week, for four weeks. The investigators will assess improvement after four weeks of cTBS. Though the study, Yale‐Brown Obsessive Compulsive Scale（Y‐BOCS）, the Dimensional Yale‐Brown Obsessive‐Compulsive Scale (DY‐BOCS), the Barratt Impulsiveness Scale‐11 (BIS‐11), the Beck Depression Inventory(BDI), the Beck Anxiety Inventory (BAI), Perceived Stress Scale(PSS), Pittsburgh sleep quality index(PSQI), the Obsessive‐Compulsive Inventory‐Revised(OCI‐R) and side effects will be obtained by a trained investigator. The patients will also receive magnetic resonance imaging scan and electroencephalography (EEG).
