What is Personality Disorder?

Personality disorders are mental illnesses that affect a patient’s ability to form and keep interpersonal relationships, adapt to the changing demands of life, and use healthy behavior patterns. People with disordered personalities often feel as though their behaviors are “normal,” but they struggle with their rigid worldviews and social difficulties.

Like all mental illnesses, a personality disorder disrupts a person’s life. Patients must meet several criteria before they receive a diagnosis of this kind. The psychologist must see deeply embedded behavior patterns that show that the patient’s perceptions, actions, thoughts, and relations with others are severely distorted.

Personality disorders tend to present in the teenage years, and symptoms continue well into adulthood. By middle age, the signs of the disease tend to be less evident than before.

How Common Are Personality Disorders?

An estimated ten percent of people in the world live with a personality disorder. While they are less common in popular media and general discussions than other disorders, personality disorders are relatively common. These disorders often occur alongside other types of mental health conditions, such as mood or anxiety disorders.
