Dissociative Disorders Flashcards
What are the DSM-V classifications of dissociative disorders?
Dissociative Identity Disorder Dissociative Amnesia With or without Dissociative Fugue Depersonalization / Derealization Disorder Other Specified Dissociative Disorder Unspecified Dissociative Disorder
What is the prevalence of dissociative disorders?
The disorders are rare.
According to DSM-V, life prevalence varies from .5 to 2.5 % in the general population
How has the prevalence of dissociative disorders changed over the years?
2 cases of DID per decade 1930-1960
20,000 cases of DID from the 1980s to 2000
Back down again after that (back to being an infrequent diagnosis)
What are the characteristics of Dissociative Identity Disorder?
A person must have at least two separate ego states (called ‘alters’) that exist independently of each other
Alters emerge and are in control at different times
Usually one primary ego state and two to four alters at time of diagnosis
Treatment sought by the primary alter
Gaps in memory occur in all cases
Existence of alters must be long-lasting and cause considerable disruption in one’s life
Often accompanied by headaches, substance abuse, phobias, hallucinations, suicide attempts, sexual dysfunction, and self-abusive behavior
and other dissociative symptoms such as amnesia and depersonalization
What are the three ways that amnesia can manifest?
Gaps in remote memory of personal life events
Lapses in dependable memory (e.g. read, computer use, etc.)
Discovery of evidence for which they have no memory
What are some elements of hypnotizability that seem related to dissociation?
the high eye-roll sign;
readiness to trust;
a relative suspension of critical judgment;
an ease of affiliation (connection) with new experiences;
a telescoped (contracted) time sense;
an easy acceptance of logical incongruities;
an excellent memory;
a capacity for intense concentration;
an overall, tractability (submissive, controllability) and, paradoxically, a rigid core of private beliefs.
Role-confusion and a subtle sense of inferiority are often evident.
What are the different forms of amnesia?
Localized: a failure to recall during a circumscribed period of time
Selective: a failure to recall some of the events
Generalized: complete loss of memory for one’s life
Systematized: failure to recall a specific category of information
Continuous: failure to recall each new event as it occurs
What is a dissociative fugue state?
Memory loss is very extensive
A person can take on a new name, new home, new job, and even new personality characteristics
The fugue is relatively brief and recovery usually complete
After recovery the person does not remember what happened during the fugue
No validation – scanty anecdotal evidence
What is the prevalence of depersonalization/derealization?
Although infrequent, single episodes are common in the general population
Prevalence of pathological form is about 2%
What does unreality/unfamiliarity refer to in relation to derealization and depersonalization?
Subjective state of feeling detached or disconnected from own being.
Sense of going through the motions, one part participating and another part observing.
Unusual sensory experiences
E.g., a person’s voice may seem strange to them, may feel not theirs.
What does hypoemotionality refer to in relation to derealization and depersonalization?
Feeling detached from own emotions, numbed or blunted
What are characteristics of derealization and depersonalization?
Unlike the other disorders, there is no disturbance of memory
Episodes are typically triggered by stress
People suddenly lose their sense of self
Usually begins in adolescence and can last a long time
Most common early disturbance related to emotional abuse
Personality disorders (Borderline, Avoidant, Obsessive-Compulsive, anxiety disorders, and depression) often comorbid
Seems linked to dissociative abilities triggered by stress
What are some examples of Other Specified Dissociative Disorders?
Some changes in identity following coercive event but no amnesia Acute dissociative reaction to stressful events Dissociative trance (not part of culture or religion)
What are Other Specified Dissociative Disorders?
Used when some symptoms are present but not enough to fully qualify as a dissociative disorder
What are the main problems with dissociation?
Has been confusion about dissociation as a symptom, a process, a pathology or an ability
Evaluated through standardized scales (e.g. DES) and clinical interview
Often used in a circular way
Now seen as a continuum between normality and pathology, but when is it one or the other?
More linked to imagination and absorption than trauma
