1. Diagnosis & Core Concepts Obsessive-Compulsive Disorder (OCD) features two main components:

• Obsessions: Recurrent, persistent, intrusive, and unwanted thoughts, images, or impulses that cause marked anxiety.
• Compulsions: Repetitive, ritualistic behaviors (e.g., handwashing, checking, counting, ordering) or mental acts performed to neutralize the anxiety.
• The Core Problem: Patients know these rituals are unreasonable but feel completely powerless to stop them. Compulsions are a desperate attempt to manage overwhelming anxiety or prevent feared consequences. OCD is a chronic condition with a strong genetic component that waxes and wanes with stress.
