Obsessive-Compulsive Disorder (OCD)
OCD is the diagnosis when the case describes recurrent obsessions or compulsions. The case must also describe that the individual recognizes that the behavior is unreasonable and excessive (i.e., there is insight). Obsessions are anxiety provoking; thoughts are intrusive and are commonly related to contamination, doubt, guilt, aggression, and sex. Compulsions are peculiar behaviors that reduce the anxiety and are most commonly habitual hand washing, organizing, checking, counting, and praying.
