Obsessive-Compulsive Disorder (OCD) is a mental health condition characterized by recurring, unwanted thoughts (obsessions) and repetitive behaviors or rituals (compulsions) that the person feels driven to perform. It can interfere with daily life and cause distress. People with OCD may experience: - **Obsessions**: Intrusive thoughts or urges, such as fears of contamination, harming others, or doubts about safety. - **Compulsions**: Repetitive actions or mental rituals, like washing hands repeatedly, checking things, or counting, done to reduce anxiety or prevent a feared event. The exact cause isn't clear, but it is thought to involve a mix of genetic, neurological, and environmental factors. OCD can be treated with therapy (such as Cognitive Behavioral Therapy, specifically Exposure and Response Prevention) and/or medication (like selective serotonin reuptake inhibitors, or SSRIs).
