Diseases and Conditions

Obsessive-compulsive disorder (OCD)

Risk factors

Factors that may increase the risk of developing or triggering obsessive-compulsive disorder include:

  • Family history. Having parents or other family members with the disorder can increase your risk of developing OCD.
  • Stressful life events. If you've experienced traumatic or stressful events, your risk may increase. This reaction may, for some reason, trigger the intrusive thoughts, rituals and emotional distress characteristic of OCD.
  • Other mental health disorders. OCD may be related to other mental health disorders, such as anxiety disorders, depression, substance abuse or tic disorders.
