OCD is defined as a mental disorder in which there are obsessive and compulsive thoughts. These obsessions are impulses which repeat uncontrollably, like a needle becoming stuck in an old record.

The mind creates messages of danger, and the mind begins focusing heavily on these messages. Consequently, the individual then has significant feelings of distress, concern, and dubiousness.
