What is "obsessive-compulsive disorder"?

Obsessive-compulsive disorder (OCD) is a mental health condition characterized by unwanted and uncontrollable thoughts, known as obsessions; and repetitive behaviors or mental acts, known as compulsions, which individuals feel forced to perform in response to these obsessions. People with OCD may experience distress or anxiety if they are unable to complete their compulsions, even though they recognize that these behaviors are excessive or irrational. Examples of obsessions include fears of contamination or doubts about safety. Examples of compulsions include excessive cleaning, checking, counting, or arranging objects in a specific way. OCD can significantly interfere with daily life, relationships, and work or school functioning. Treatment typically involves therapy and sometimes medication to help manage symptoms and improve quality of life.
