Dr. Roumen Milev, Queen's University

Brief Summary:
Low frequency (1Hz) rTMS applied bilaterally and simultaneously over SMA for 6 weeks in addition to the standard treatment regimen for OCD, will lead to significant improvement in patients' symptoms. The clinical improvement detected by YBOCS, CGI and SF-36 QOLS scores will be statistically significant in active treatment group compared to sham (placebo) treatment group.
