Compulsions are repetitive actions or mental rituals performed to reduce the distress associated with obsessions or to prevent a feared event. Common compulsions include excessive hand washing, checking, counting, arranging objects in a specific way, and repeated mental rituals like praying or counting. OCD typically begins in adolescence or early adulthood, but it can also start in childhood. The exact cause of OCD is not fully understood, but it is believed to involve a combination of genetic, neurological, behavioral, cognitive, and environmental factors.

Treatment for OCD focuses on reducing the severity of symptoms and improving overall functioning. The primary treatments include cognitive-behavioral therapy (CBT), specifically a type called Exposure and Response Prevention (ERP), and medication, particularly selective serotonin reuptake inhibitors (SSRIs). ERP helps individuals confront their obsessions and gradually reduce their compulsive behaviors.

Support from family, friends, and healthcare providers is crucial for individuals with OCD. Encouragement and understanding can help individuals adhere to treatment plans and make significant progress. With appropriate treatment and support, many individuals with OCD can manage their symptoms effectively and lead fulfilling lives.
