Obsessive-compulsive disorder (OCD) is a mental disorder in which you have thoughts (obsessions) and rituals (compulsions) over and over. They interfere with your life, but you cannot control or stop them. The cause of obsessive-compulsive disorder (OCD) is unknown. Factors such as genetics, brain biology and chemistry, and your environment may play a role. Obsessive-compulsive disorder (OCD) usually begins when you are a teen or young adult. Boys often develop OCD at a younger age than girls. Risk factors for OCD include Family history. People with a first-degree relative (such as a parent, sibling, or child) who has OCD are at higher risk. This is especially true if the relative developed OCD as a child or teen.; Brain structure and functioning. Imaging studies have shown that people with OCD have differences in certain parts of the brain. Researchers need to do more studies to understand the connection between the brain differences and OCD.; Childhood trauma, such as child abuse. Some studies have found a link between trauma in childhood and OCD. More research is needed to understand this relationship better.MedlinePlusU.S. National Library of Medicine, 2021
