Personality disorders are characterized by long-standing, pervasive, and inflexible patterns of inner experience and behavior that deviate from the individual’s cultural norms. These patterns may involve ways of thinking, mood, interpersonal relationships, and impulse control. Some of these patterns are similar to features of other mental disorders. The distinction between symptoms of a personality disorder and those of another mental disorder is the former’s long-standing, pervasive, and inflexible nature. Like other mental disorders, personality disorders may cause the individual significant distress or create problems in one’s occupational, social, or other areas of life. Personality disorders are usually products of both the person’s biology and experience.
Personality disorders involve traits that tend to be stable over time. They tend to become apparent in early adulthood. It is rare for children to be diagnosed with personality disorders because those traits are still likely to change. The 12-month lifetime prevalence of any personality disorder is 9.1% in the U.S. adult population. There are also some gender differences. For example, men are more likely to be diagnosed with antisocial personality disorder while women are more likely to be diagnosed with borderline personality disorder.
There are ten personality disorders, but they can be categorized under three types, which are as follows.
Odd and Eccentric type
Dramatic, emotional, and erratic type
Anxious and fearful type
