Post traumatic stress disorders dissociative and somatoform disorders

Post-Traumatic Stress Disorders, Dissociative and Somatoform Disorders

Chapter 7


Overview

Overview

  • Dissociation (def)-the disruption of the normally integrated mental processes involved in memory or consciousness.


Stress disorders

Stress Disorders

  • Acute Stress Disorder (ASD)-short term reaction to trauma, characterized by symptoms of dissociation, re-experiencing avoidance, and increases anxiety or arousal.

  • Post Traumatic Stress Disorder (PTSD)-characterized by persistent, maladaptive disruptions in the integration of memory, consciousness, or identity.


Dissociative disorders

Dissociative Disorders

  • Dissociative Fugue-characterized by sudden and unexpected travel away from home, and an inability to recall the past, as well as confusion as to one’s identity or the assumption of a new identity.

  • Dissociative Amnesia-Sudden inability to recall extensive and important personal information that exceeds normal forgetfulness.

  • Dissociative Identity Disorder (DID) aka MPD- characterized by the existence of two or more distinct personalities in a single individual


Somatization disorder

Somatization Disorder

  • Hypochondriasis-belief that the individual is suffering from a physical illness.

  • Pain Disorder-characterized by a preoccupation with pain.

  • Body Dsymorphic disorder-patient is pre-occupied with some imagined defect in appearancetypically a facial feature


Traumatic stress

Traumatic Stress

  • (def)-DSM IV –event that involves actual or threatened death to self or others, creating feelings of intense fear, helplessness or horror.

  • Both survivors and witnesses are expected to be greatly distressed as part of their normal response to traumatic stress.


Acute and post traumatic stress disorders symptoms and features

Acute and Post traumatic Stress Disorders: Symptoms and Features

  • Major Difference is Duration.

    • ASD-develops within 4 weeks

    • Delayed

  • Both characterized by several similar features:

    • Flashbacks-re-experiencing or “reliving” the trauma

    • Marked avoidance of stimuli associated with the trauma

    • Persistent arousal or anxiety


Dissociative symptoms asd

Dissociative Symptoms (ASD)

  • Depersonalization-report feeling dazed or spaced out..

  • De-realization-marked sense of unreality about self or environment.

  • Dissociative amnesia-inability to recall certain aspects of the experience.


Etiology

Etiology

  • Social Factors

    • PTSD more likely to develop as a result of rape or combat, especially if the person suffered physical harm.

    • Social support-lack of support is a strong predictor in the development of both ASD and PTSD


Etiology1

Etiology

  • Biological Factors

    • Family history of mental disorders

    • Women and minorities


Etiology2

Etiology

  • Psychological Factors

    • Two Factor theoryCombination of Classical and Operant Conditioning

    • Cognitive Factors

      • Expectancy

      • Preparedness

      • Control

    • Emotional Processing


Essential elements for successful emotional processing

Essential Elements for Successful Emotional Processing

  • Victim must find a way to be emotionally engaged with the memory.

  • Victims must be able to talk about the experience

  • Victims must learn to develop a balanced view of the world againmeaning making-in the process of integrating the trauma into their belief system and memories people often find some higher value for enduring the trauma


Biological consequences of exposure

Biological Consequences of Exposure

  • Alterations of function and structure of the amygdale and hippocampus associated with increased fear reactivity and intrusive memories following a traumatic event.

  • Increased levels of general arousal such as a higher resting heart rate and increased levels of NEsuggest the sensitization of the sympathetic nervous system and heightened fear response and reactivity.

  • Possible explanations include a failure of the stress response system and continued activation of the Hypothalamic Pituitary Axis.

  • People with PTSD show lower levels of cortisol instead of higher as anticipated, indicating that the stress response activated by the stressful event is not turned off in people with PTSD.


Prevention and treatment

Prevention and Treatment

  • Interventions

  • Critical Incident Stress (CIS)

  • Emergency Treatment of Trauma Victims.

  • Critical Incident Stress De-briefing.


Treatment of asd

Treatment of ASD

  • Based on Cognitive Behavior Therapy

    • First, establish a trusting therapeutic relationship.

    • Provide education abut the process of coping with trauma

    • Stress Management Training

    • Encourage Re-experience of the trauma

    • Integrating the traumatic event into the individual’s experience.


Treatment of ptsd

Treatment of PTSD

  • Cognitive Behavioral Therapy-same as ASD, but longer in duration.

  • Anti-depressant therapy-recently approved

  • Re-exposure to the traumatic event

  • Imagery Rehearsal therapy

  • Eye Movement Desensitization


Dissociative disorders1

Dissociative Disorders

  • Controversy as to the extent to which these disorders exist

  • Unconscious processes do exist and they play a role in both normal and abnormal cognition.


Classification dsm iv tr

Classification (DSM-IV-TR)

  • Dissociative Fugue-purposeful travel away from home, accompanied by confusion of identity and memory loss as a response to the trauma.

  • Dissociative Amnesia-sudden inability to recall extensive personal information.

  • Depersonalization-less dramatic problem characterized by severe and persistent feelings of being detached from onesself.


Classification

Classification

  • Dissociative Identity Disorder (DID)-rare disorder characterized by the existence of two or more distinct personalities in a single individual.

    • At least two of the personalities (alters) repeatedly take control of the person’s behavior.

    • Individual is unable to remember events or information when the other personalities are in control.

    • Original Personality may or may not be aware of the alters.


Did disorder or not

DID: Disorder or Not?

  • Two Extremes of the debate

  • Reasons for Skepticism

    • Frequency of diagnosis increased significantly after the release of the book and movie Sybil.

    • Number of personalities co-existing in an individual has gone from 3-4 to more than 100.

    • DID rarely diagnosed outside the US and Canada

  • Cases of Malingering: Kenneth Bianchi


Psychological factors of dissociative disorders

Psychological Factors of Dissociative Disorders

  • Dissociative fugue, amnesia and depersonalization can usually be traced to a specific traumatic experience.

  • Association between trauma and DID is much less clear.


Theories of psychological factors related to did

Theories of Psychological Factors related to DID

  • Early Child Abuse

  • Abuse overwhelms a child’s psychological defense mechanisms, and with continued abuse, dissociation becomes a means of coping.

  • Problem: case studies that report abuse are based on patient’s memories and clinicians evaluations. These are not objective assessments of the past as memories may be selectively recalled, distorted, or created to conform with subsequent experiences.


Biological factors

Biological Factors

  • Twin Studies have found no genetic contribution to dissociative symptoms and suggest it is a factor of shared family environment.

  • There may be indications that there are biological causes not yet discovered due to the development of similar symptoms due to drug abuse and aging.


Social factors

Social Factors

  • Iatrogenesis-the manufacture of the dissociative disorder by the treatment.

  • Expectation and leading questions of the therapist.

  • Diagnosis of DID in Turkey


Treatment of dissociative disorders

Treatment of Dissociative Disorders

  • Uncovering and recounting the past traumatic events.

  • Hypnosis

  • Medication to reduce distress

  • Treatment for DIDintegration of personalities

  • Effectiveness of treatment


Somatoform disorders

Somatoform Disorders

  • Patient does feel pain as the problem is real in the mind of the patient.

  • Can be very dramatic such as blindness and paralysis.

  • More often the person suffers from numerous complaints such as stomach upset, chronic pain and dizziness.

  • Some types of somatoform disorders are defined by a preoccupation with a particular body part or with fears about a particular illness.


Classification1

Classification

  • Conversion Disorder -central assumption that psychological conflicts are converted into physical symptoms

  • Somatization Disorder -(more common) characterized by a history of multiple physical complaints in the absence of a physical cause.

  • Hypochondriasis - fear or belief that one is suffering from a physical illness worries must last at least 6 months and medical evaluations do not alleviate the fear of the disease.

  • Pain Disorder - complaints seem excessive and are motivated at least in part by psychological factors such as the attention the illness brings them.

  • Body Dysmorphic Disorder - preoccupation with some imagined defect that far exceeds normal worries about physical imperfection.


Malingering and factitious disorder

Malingering and Factitious Disorder

  • Malingering-pretending to have a somatoform disorder to achieve some external gain such as disability payment.

  • Factitious Disorder-unlike malingering, although the condition is also faked, the motivation is a desire to assume the sick role. Repetitive patter of the disorder is called Munchhausen Syndrome


Biological factors1

Biological Factors

  • None

  • Diagnosis by exclusion


Psychological factors

Psychological Factors

  • Lack of Research

  • Traumatic Stress appears to be a factor

  • Hypervigilance


Social factors1
