Features of Dissociative Amnesia
- Uncommon (often in adolescent and young females, and in young men during wartime)

- During amnestic episode there is disorientation and perplexity
- Recovery is complete recurrences are rare
Etiology of Dissociative Amnesia
- Follows severe psychosocial stress involving threat of injury or death
- Psychosocially distressing knowledge is repressed
Treatment Dissociative Amnesia
Hypnosis may be useful if person wants memory recovered
Why might a memory not return during dissociative amnesia treatment?
A memory is too distressing
Dissociative Fugue Assessment
- Sudden unexpected travel away from home, unable to recall personal information

- Having an actual physical disordr with similar features is a risk factor
- Lack of insight, repression, and secondary reward (disability sometimes prevents person from something they do not want to do. they are not able to admit this to themselves. Repression keeps the conflict out of awareness. Symtpoms maintained by rewarding consequences of avoidance and/ or attention/ sympathy received)
Conversion Disorder Treatment

- Eliminate secondary reward
- Reduce stress
- Hypnosis to remove symptom
What is Mass Conversion Disorder?
- When a group of people develop the same set of psychosomatic
- Much rarer
What is the Historical Perspective on Psychosomatic Disorders?
- Psychosomatic symtpoms have changed over time reflecting societal beliefs/ concerns
- Pseudoseizures and paralysis common conversion symptoms historically, but much less common today
- In 1890s, coincident with interest in hypnosis, many people reported being in permanent hypnotic state
- Neurasthenia ‘nervous exhaustion’ became popular in late 1890s and continued for several decades (one of the most common diagnoses in early 1900s, but disappeared by WWI
What are some modern conditions that may have replaced these historical conditions?
