F42.2 clinical information

Obsessive-Compulsive Disorder (or OCD for short) is a type of mental health condition where intrusive thoughts and impulses plague a person’s mind. To respond to these impulses, people who have OCD engage in behavior or acts that they can enact physically or mentally. People who have OCD will experience it to varying degrees. Some people who have OCD are still able to live normally without it being a problem, but some are bothered to the degree that they affect their daily life and even their relationships.

A person who has Obsessive-Compulsive Disorder will have the following symptoms:

  • They have these excessive thoughts and behaviors they can’t control. They also acknowledge that these thoughts and behaviors are extreme and sometimes non-sensical. They also dwell on these thoughts and behaviors for at least an hour at several intervals in a day
  • Their responses to their excessive thoughts and behaviors are made simply to help them find relief from the distress caused by them. They don’t necessarily derive any pleasure from what they do as a response to those.
  • Their obsessions (thoughts) and compulsions (behaviors) have caused and are causing significant problems in their lives.

To help people work through OCD, they can take anti-depressants or other psychiatric medicines. A non-medical way to treat OCD is to enroll the patient in a Cognitive Behavioral Therapy program to learn healthier ways of thinking and reacting to combat their obsessions and compulsions.
