Personality disorders


  • Impairments of temperament

Nature

A personality disorder exists when the habits that constitute a personality are inflexible and damaging. Inflexible and maladaptive personality traits can cause significant impairment in social or occupational functioning or subjective distress. In some cases, one may not realize that they have a personality disorder because thier way of thinking and behaving seems natural. And they may blame others for the challenges they face. Personality disorders usually begin in the teenage years or early adulthood. There are many types of personality disorders. Some types may become less obvious throughout middle age.

Background

It is not easy to distinguish the influence of personality from that of more transient states and situations. One source of confusion is social roles. Family therapists have suggested that some apparently individual characteristics are best thought of as features of the 'family system' - a result of relations among family members not attributable to any one of them. Certain situations seem almost designed to bring out behaviour that is easy to mistake for a personality trait. Famous experiments by Stanley Milgram show that most people can bring themselves to behave sadistically under the influence of a person claiming authority. According to some sceptics, the sullen compliance combined with deliberate dawdling identified as a feature of passive-aggressive personality is simply the way people act when they are under compulsion and resisting demands for adequate performance because they have little to gain from it. Historians and sociologists have described slaves and army privates as behaving this way.

Another complication is the influence of emotional states and mental illnesses. Anyone may seem utterly transformed by chronic depression or alcoholism. Professionals who did not take sufficient notice of this once spoke of the alcoholic personality. The difficulty of distinguishing personality traits from states of mind and the demands of social roles is so serious that a few researchers have even denied the existence of individual patterns that persist in every mood and social context.

In the first two editions of the American Psychiatric Association's Diagnostic and Statistical Manual (DSM-I and DSM-II), personality disorders were relegated to a secondary place along with a mixture of other conditions; symptom disorders had priority. The third edition (DSM-III), published in 1980, gave equal prominence to personality disorders for the first time. The diagnostic scheme was strongly criticized from the start and has already been revised once, in the new edition published in 1987 (DSM-III-R). It will certainly be revised further, but the main outlines drawn a decade ago remain. DSM-III-R still dominates the field and provides at least a starting point for many mental health professionals in their consideration of personality problems.

Incidence

Types of personality disorders are grouped into three clusters, based on similar characteristics and symptoms. Many people with one personality disorder also have signs and symptoms of at least one additional personality disorder. It's not necessary to exhibit all the signs and symptoms listed for a disorder to be diagnosed.

Cluster A personality disorders are characterized by odd, eccentric thinking or behavior. They include paranoid personality disorder, schizoid personality disorder and schizotypal personality disorder.

Cluster B personality disorders are characterized by dramatic, overly emotional or unpredictable thinking or behavior. They include antisocial personality disorder, borderline personality disorder, histrionic personality disorder and narcissistic personality disorder.

Cluster C personality disorders are characterized by anxious, fearful thinking or behavior. They include avoidant personality disorder, dependent personality disorder and obsessive-compulsive personality disorder.
