Explanation:

In psychiatry, an obsessive-compulsive disorder, or OCD, is a type of mental disorder where an individual is plagued by obsessions, or unwanted and repetitive thoughts, or feel that they must carry out certain behaviors in very specific manners, which are termed compulsions. Examples of obsessive thoughts include worrying excessively with how other perceive the individual, or unwanted sexual thoughts about some people. Some common compulsive behaviors include things such as frequent, excessive, and often unnecessary hand-washing, or having to order and arrange things in a certain way. Failure to follow on with the compulsive behavior can produce a great deal of stress and anxiety. OCD is often a debilitating condition that can severely impair the quality of life of the individual, can lead to other mental disorders, and can increase the risk of self-harm.
