Schizoid Personality Disorder

What Are Personality Disorders?

People with personality disorders have long-standing patterns of thinking and acting that differ from what society considers usual or normal. The inflexibility of their personality can cause great distress, and can interfere with many areas of life, including social and work functioning. People with personality disorders generally also have poor coping skills and difficulty forming healthy relationships.

Unlike people with anxiety disorders, who know they have a problem but are unable to control it, people with personality disorders generally are not aware that they have a problem and do not believe they have anything to control. Because they often do not believe they have a disorder, people with personality disorders often do not seek treatment.

Food Addiction

The idea that a person can be addicted to food has recently gotten more support from science. Experiments in animals and humans show that, for some people, the same reward and pleasure centers of the brain that are triggered by addictive drugs like cocaine and heroin are also activated by food, especially highly palatable foods.

What Is Schizoid Personality Disorder?

Schizoid personality disorder is one of a group of conditions called "Cluster 'A' " or eccentric personality disorders. People with these disorders often appear odd or peculiar. People with schizoid personality disorder also tend to be distant, detached, and indifferent to social relationships. They generally are loners who prefer solitary activities and rarely express strong emotion. Although their names sound alike and they might have some similar symptoms, schizoid personality disorder is not the same thing as schizophrenia. Many people with schizoid personality disorder are able to function fairly well, although they tend to choose jobs that allow them to work alone, such as night security officers, library, or lab workers.

What Are the Symptoms of Schizoid Personality Disorder?

People with schizoid personality disorder often are reclusive, organizing their lives to avoid contact with other people. Many never marry or may continue to live with their parents as adults. Other common traits of people with this disorder include the following:

  • They do not desire or enjoy close relationships, even with family members.
  • They choose solitary jobs and activities.
  • They take pleasure in few activities, including sex.
  • They have no close friends, except first-degree relatives.
  • They have difficulty relating to others.
  • They are indifferent to praise or criticism.
  • They are aloof and show little emotion.
  • They might daydream and/or create vivid fantasies of complex inner lives.

How Common Is Schizoid Personality Disorder?

It is difficult to accurately assess the prevalence of this disorder, because people with schizoid personality disorder rarely seek treatment. Schizoid personality disorder affects men more often than women, and is more common in people who have close relatives with schizophrenia.

Schizoid personality disorder usually begins in late adolescence or early adulthood.

What Causes Schizoid Personality Disorder?

Little is known about the cause of schizoid personality disorder, but both genetics and environment are suspected to play a role. Some mental health professionals speculate that a bleak childhood where warmth and emotion were absent contributes to the development of the disorder. The higher risk for schizoid personality disorder in families of schizophrenics suggests that a genetic susceptibility for the disorder might be inherited.
