Obsessions and compulsions are the two central features of OCD, according to the DSM-5. Obsessions are persistent unwanted thoughts, urges, or images that cause distress and that individual tries to suppress or counteract. Compulsions are repetitive behaviors or mental acts that the individual performs in response to an obsession, with the goal of neutralizing the threat or alleviating distress. In addition, obsessions or compulsions must impair an aspect of daily functioning, be fairly time-consuming, and not be due to another mental health condition or substance use for a diagnosis.
