Obsessive Compulsive Disorder (OCD)
From time to time, almost everyone has a disturbing thought or checks more than once they have locked the door. For most people these thoughts and actions can be forgotten. But if a person has OCD, the thoughts and feelings of discomfort can take over and they will feel anxious until they have done something to help them to deal with the thought. Obsessive-compulsive disorder (or OCD for short) is the name given to a condition in which a person has obsessions and/or compulsions, but usually both.
