Personality disorders are chronic and persistent behavioral and emotional disturbances that are often difficult to treat. Some professionals argue that these disorders are not mental disorders at all, but personality styles—that these individuals are just odd or unusual. Use a minimum of two peer-reviewed references and develop an argument for or against the inclusion of personality disorders as a diagnostic category in the next version of the DSM. Be sure to support your position with relevant research on the causation, diagnosis, and treatment of personality disorders.
