Personality disorder
Personality disorders are a form of mental disorder. They are characterised by cognitive and behavioural patterns that differ markedly from the expectations of the individual's culture, are pervasive and inflexible, are recognisable in adolescence or early adulthood and lead to significant distress or impairment in personal, social and occupational situations. Personality disorders are represented on Axis II of the DSM-IV, and are particularly controversial because their comorbidity rate is excessively high, indictative of poor categorization.
The ten types of personality disorders that have been defined are:
Cluster A (odd or eccentric disorders)
Cluster B (dramatic, emotional, or erratic disorders)
Cluster C (anxious or fearful disorders)
