Obsessions are recurrent and persistent thoughts, urges or images that are experienced, at some time during the disturbance, as intrusive, unwanted, and that in most individuals cause marked anxiety or distress (DSM-V, 300.3). OCD is a prevalent psychiatric disorder, with an incidence rate of between 1.5–3% across all ethnic and cultural groups. The average age of onset is in adolescence or early adulthood with a separate peak in childhood, contributing to a significant lifetime disease burden. Despite this severity and prevalence, effective treatments for OCD are still limited. Only 10–15% of people experience remission with serotonin reuptake inhibitors, the only proven pharmacological monotherapy for OCD. While exposure-therapy with response prevention (ERP) shows significant efficacy, it can be challenging for patients to complete even if they are able to find experienced treatment providers. Comorbidity with other mental health disorders include anxiety disorders such as panic disorder, phobias, and PTSD (75.8%); Mood disorders, including major depressive disorder and bipolar disorder (63.3%); Impulse-control disorders, including ADHD (55.9%); and substance use disorders (38.6%).
