When unwanted thoughts or rituals take over
Obsessive-compulsive disorder (OCD) involves recurring, unwanted thoughts, urges, or images called obsessions; repetitive behaviors or mental acts called compulsions; or both. These symptoms can be time-consuming, distressing, and difficult to control.
OCD is not simply liking order or cleanliness. Symptoms can affect relationships, work, sleep, routines, and the ability to leave home or complete ordinary tasks.
