Personality Disorders

Module 31

Clarify

• Dissociation is not the same as psychosis. Dissociation involves breaking away from the sense of self, either by losing memory and identity or by adding personalities. Psychosis involves a break with reality, believing things that are untrue, or having hallunciations about things that aren’t there.

Dissociative Disorders

Module 31: Dissociative, Schizophrenia, and Personality Disorders

Dissociative Disorders

• Disorders in which the sense of self has become separated (dissociated) from previous memories, thoughts, or feelings

Types of Dissociative Disorders

• Three main types:– Dissociative Amnesia– Dissociative Fugue– Dissociative Identity Disorder

Dissociative Disorders

Dissociative Disorders:

Dissociative Amnesia

Module 31: Dissociative, Schizophrenia, and Personality Disorders

Dissociative Amnesia

• A dissociative disorder characterized by loss of memory in reaction to a traumatic event

• Example: soldiers in combat– Young man in a boat wreck; only survivor;

traumatic and so losses memory of incident.

Dissociative Disorders:

Dissociative Fugue(fUge)

Module 31: Dissociative, Schizophrenia, and Personality Disorders

Dissociative Fugue

• A dissociative disorder characterized by loss of identity and travel to a new location– From the same root word as fugitive.

• The person may develop a new identity and begin a new life.– Can last a few hours, months or even years.– Unconscious response to stress (as with other

dissociative disorders)

Dissociative Disorders:

Dissociative Identity Disorder

Module 31: Dissociative, Schizophrenia, and Personality Disorders

Dissociative Identity Disorder

• Rare and controversial dissociative disorder in which an individual experiences two or more distinct and alternating personalities

• Formerly called multiple personalities– Before the 1970s fewer than 100 cases had ever

been reported.– In the 1980s alone, reports of more than 20,000

diagnosed cases appeared, almost all of them in North America

Controversy

• Psychologists debate whether is really exists. Are today’s clinicians simply more knowledgeable and willing to make a diagnosis? Are there better diagnostic rules (thus reducing the number of cases that were misdiagnosed as other things, like schizophrenia)?

• Skeptics believe the power of suggestion has been at work. Clinicians (who have read about the disorder) may be unintentionally suggesting multiple personalities to their clients.

psychological disorder.– “Schiz” means split, but not slit from personality; it’s a

split from reality– Affects 1% of the world’s population; typically develops

in late adolescence or early adulthood and strikes men at a slightly greater rate than women.

• Brain structure of those with schizophrenia is different than the normal brain

• Those with schizophrenia have smaller amounts of brain tissue and larger fluid filled spaces.

• The thalamus is smaller in those with schizophrenia.

Biological Factors – Brain Function

• The brain of those with schizophrenia operates differently than the normal brain.

• The frontal lobes show less activity.• Those with schizophrenia have a larger

number of receptor sites for the neurotransmitter dopamine.
