Obsessive-compulsive disorder (OCD) is an anxiety disorder where a person has obsessive thoughts and/or compulsive activity (commonly both).

  • An obsession is an unwanted and unpleasant thought, image or urge that repeatedly enters a person's mind, causing feelings of anxiety, disgust or unease.
  • A compulsion is a repetitive behaviour or mental act that someone feels they need to carry out to try to temporarily relieve the unpleasant feelings brought on by the obsessive thought

Other anxiety disorders include PTSD and GAD.
