Personality Disorders
Personality is a long-term pattern of perceiving, relating to and thinking about oneself and the environment. Current personality theories tends to distinguish between temperament (which is viewed as innate or genetic) and character (which is learned). A personality disorder occurs when these two components (nature and nurture) combine in such a manner that the person develops inappropriate, ineffective, or painful ways of behaving and interacting. Because personality disorders are enduring, they tend to be very difficult to treat and change. In rehabilitation, a personality disorder will often be a secondary disability.

There are Three Clusters of Personality Disorders:
