SYMPTOMS

Personality Disorders

Personality disorders are types of mental disorders in which people have rigid and unhealthy patterns of thinking, functioning and behaving. An individual with a personality disorder has trouble perceiving and relating to situations and people. These cause significant problems and limitations in relationships, work, school and social activities. This individual may not realise that they have a personality disorder because their way of thinking and behaving seems natural to them, and they blame others for the challenges they face.

Personality disorders usually begin in the teenage years or early adulthood, with some types becoming less obvious throughout middle age.

Causes:

Personality is the combination of thoughts, emotions and behaviours that make you unique. It is the way you view, relate to and understand the outside world, as well as how you view yourself. It forms during childhood, and is shaped though an interaction of:

  • Your genes. Traits that may be passed on through inherited genes are sometimes called your temperament.
  • The environment. The surroundings in which you grew up, events that have occurred and your relationships with family and others.

Personality disorders are thought to be a combination of these influences. Genes may make you vulnerable to developing a personality disorder, and a life situation may trigger its actual development.

Although the precise cause of personality disorders is not known, certain factors seem to increase the risk of triggering or developing them, including:

  • Family history of mental illness.
  • Abusive, unstable or chaotic family life during childhood.
  • Variations in brain chemistry and structure.
  • Being diagnosed with childhood conduct disorder.

Personality disorders can disrupt both the person with the disorder and the people close to them. They may cause relationship, work or school problems, and can lead to social isolation or alcohol/drug abuse.

Symptoms:

Personality disorder types are grouped into clusters based on similar characteristics and symptoms. Many people with one personality disorder also have signs and symptoms of at least one additional disorder. It is not necessary to exhibit all the signs and symptoms listed in order to be diagnosed.
