Obsessive-Compulsive Disorder (OCD) is a mental health disorder characterized by unwanted, intrusive thoughts (obsessions) and repetitive, ritualistic behaviors (compulsions) that are difficult to control. These obsessions and compulsions can significantly interfere with daily activities and quality of life.

The exact cause of OCD is not fully understood, but it is believed to be caused by a combination of genetic, environmental, and brain chemistry factors. Risk factors for OCD include a family history of the disorder, stress, and trauma.

Treatment for OCD typically involves a combination of medication and psychotherapy, such as cognitive-behavioral therapy (CBT) or exposure and response prevention (ERP) therapy. Medications, such as selective serotonin reuptake inhibitors (SSRIs), can help reduce symptoms of OCD. Psychotherapy can help individuals with OCD identify and challenge negative thought patterns, develop coping strategies, and gradually reduce compulsive behaviors through exposure to feared situations.
