Impairments of temperament

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. 


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.
