An overview of the theoretical models of OCD are provided, and evidence-based treatments for OCD, specifically cognitive behavioral therapy (CBT) with exposure and response prevention (ERP), pharmacotherapy, and neurosurgery, are discussed. The chapter concludes with suggestions for future research directions.
