Personality Disorders

Personality disorders defined:

The U.S. National Library of Medicine defines personality disorders as a group of behavioral health conditions in which a person has a long-term pattern of behaviors, emotions, and thoughts that is very different from his or her culture’s expectations. These behaviors interfere with the person’s ability to function in relationships, work, or other settings. There are ten specific personality disorders which have been classified into three clusters by the American Psychiatric Association. Cluster A: Odd or eccentric behavior; Cluster B: Dramatic, emotional or erratic behavior; Cluster C: Anxious fearful behavior. According to the National Institute of Mental Health (NIMH), 9% of adults have a personality disorder of some kind with most disorders developing by early adulthood.
