Chapter 6 Flashcards
Supernatural explanations
Dissociation and related complaints were now seen as the result of demonic possession, and exorcism was the favoured treatment
History: Dissociative disorders and Somatic symptom disorders viewed as Hysteria
An outdated psychiatric term once used to describe a symptom pattern characterized by emotional excitability and physical symptoms (e.g., convulsions, paralyses, numbness, loss of vision) without any organic cause.
-Caused in women by a wandering womb (hysteros)
Freud and Beuer hysteria
posited that trauma, often of a sexual nature, was a predisposing factor for hysteria and established a relationship between dissociation and hypnotic-like states
Freud Conversion symptoms as expressions of unconscious psychological conflicts
He suggested that “conversion” of anxiety to more acceptable physical symptoms relieved the pressure of having to deal directly with the conflict. This avoidance of conflict was termed primary gain and was viewed as the main reinforcement maintaining the somatic symptoms. Freud also recognized that hysterical symptoms could help a patient avoid responsibility and gain attention and sympathy, referring to these reinforcements as secondary gains of the symptoms. The term secondary gain is still commonly used today to refer to the benefits a patient may either unknowingly or knowingly seek by adopting the sick role.
Dissociative disorders
are characterized by severe maladaptive disruptions or alterations of identity, memory, and consciousness that are experienced as being beyond one’s control
Main symptom of dissociative disorders
Dissociation- the lack of normal integration of one or more aspects of psychological functioning, such as identity, memory, consciousness, emotion, sensorimotor functioning, or behaviour
Dissociative tendency fall into two main groups
1) involves mild, non-pathological forms of dissociation, such as absorption and imaginative involvement, that are normally distributed on a continuum across the general population
2) involves more severe, pathological types of experiences, such as amnesia, derealization, depersonalization, and identity alteration, that do not normally occur in the general population and that form a discrete category or taxon
Memories repressed
Referring to memories that a person cannot call into awareness, but that remain in the person’s subconscious and can be retrieved under certain conditions or with the help of a psychotherapist.
Three Major Dissociative Disorders
dissociative amnesia (which includes dissociative fugue as a subtype), depersonalization/derealization disorder, and dissociative identity disorder (formerly known as multiple personality disorder)
Dissociative amnesia
Inability to recall important personal information
-Includes dissociative fugue, a rare condition in which individuals unexpectedly leave home and may turn up in a distant city with no memory of their past
Dissociative identity disorder
-Presence of two or more personality states
-Formerly known as multiple personality disorder; the classic case is The Three Faces of Eve
Depersonalization/derealizatin disorder
Feeling of being detached from oneself and one’s physical and social environment
-Depersonalization experienced for a short period of time is very common and not pathological
Dissociative amnesia occurence
following a traumatic event, such as an automobile accident, or exposure to war trauma or torture that many people have confronted before claiming refugee status in Canada. Afflicted individuals usually have no memory of the precipitating traumatic event, and may be unable to recall their own name, occupation, and other autobiographical information, even though they may still retain general knowledge of world events, such as the name of the current prime minister of Canada
Four patterns of Dissociative Amnesia
(1) localized amnesia, wherein the person fails to recall information from a very specific time period (e.g., the events immediately surrounding a trauma); (2) selective amnesia, wherein only parts of the trauma are forgotten while other parts are remembered; (3) generalized amnesia, wherein the person forgets all personal information from their past; and (4) systematized amnesia, wherein the individual only forgets certain categories of information, such as certain people or places.
Subtype of Dissociative Amnesia: Dissociative Fugue
A type of dissociative amnesia in which an individual suddenly and unexpectedly travels away from home and may take up a new identity, accompanied by a loss of memory for their own identity or other important biographical information.
-The fugue is usually brief in duration, lasting from a few days to a few weeks, but there are rare cases where the individual disappears for a prolonged period of time. The behaviour of individuals presenting with dissociative fugue is not all that unusual; they are able to function reasonably well and may even successfully adopt a new identity and occupation if the disorder is prolonged. Dissociative fugue may end either abruptly or gradually with persistent confusion or amnesia about identity. Often, those who have recovered from the disorder report no memory of what occurred during the fugue state.
Depersonalization/derealization disorder
is a dissociative disorder in which the individual has persistent or recurrent experiences of depersonalization and/or derealization
Depersonalization
is a condition in which individuals have a distinct sense of unreality and detachment from their own thoughts, feelings, sensations, actions, or body. Fleeting experiences of depersonalization are relatively common, with approximately half of the general population reporting such symptoms, often during times of stress
Depersonalization/derealization disorder diagnosed
only when severe depersonalization is the primary problem, and when the symptoms are persistent and cause clinically significant impairment or distress. Individuals with this disorder experience recurrent episodes of depersonalization, in which they feel as though they are living in a dream, observing their own mental processes or body from the outside, or as if time is moving slowly. They commonly describe feeling like a robot that is able to respond to their environment, but without feeling connected to their actions
Derealization
A dissociative symptom in which one has a sense of unreality or detachment with respect to objects or other people in the environment, experiencing them as unreal, dreamlike, foggy, or distorted.
Disorder is present
-High rates of comorbidity with anxiety, depression, personality disorders, and other dissociative disorders have been found
-reduced emotional reactivity to stressful or emotionally arousing stimuli
-Cognitive disruptions in perceptual and attentional processes
Brain regions and the disorder
reduced activity in brain regions responsible for processing emotional information (e.g., the insula and limbic regions including hypothalamus and amygdala) is associated with depersonalization/derealization
Dissociative Identity Disorder (DID)
The most severe and chronic of the dissociative disorders, characterized by the existence of two or more unique personalities in a single individual. Each personality may have its own constellation of behaviour, tone of voice, and physical gestures, and so on.
DID: Alternative personality states
resemble different identities or personalities that periodically intrude into the consciousness and assume control of a person’s behaviour.
Alters: DID
Refers to each of the unique personalities in an individual who has dissociative identity disorder (DID). Alters may be very different from each other, with opposite personality traits (e.g., one very extraverted and another very introverted) and differences in the age, sex, race, and family history they claim to have.
Switching: DID
The transition from one alter to another in an individual with dissociative identity disorder. Occurs suddenly and is often precipitated by stress or some other identifiable cue in the surrounding environment.
Diagnosis of DID
no longer required to display distinct “identities” that appear to “take control” of behaviour in order to receive a diagnosis of this disorder. Instead, it is recognized that alternative personality states may vary according to their level of overtness, and signs of identity disturbance may be quite subtle. For example, the emergence of an alternative personality state could correspond with the sudden occurrence of emotions or behaviours that individuals find perplexing and not within their control.
Self destructive behaviour in DID
elf-inflicted burns, wrist slashing, and overdosing
-Suicide attempts
Two competiting theories of the etiology of dissociative identity disorder
1) Trauma Model
2)Socio-cognitive model
The trauma model
The theory that dissociative identity disorder is caused by severe childhood trauma, including sexual, physical, and emotional abuse, accompanied by personality traits that predispose the individual to employ dissociation as a defence mechanism or coping strategy.
For children, dissociation can imply
means of escape when no other means is possible. If the child can escape into a fantasy world and become somebody else and if this escape blunts the physical and emotional pain temporarily, they will likely do it again
Brain areas affected due to DID
smaller cortical and subcortical volumes in areas of the brain that involve perception and personal awareness (hippocampus, amygdala, parietal structures) and in brain regions that pertain to movement and fear learning (frontal cortical structures). They also exhibit larger white matter tracts, responsible for communication between somatosensory association areas
Attachment theory and DID
The lack of such sensitive responding by the caregiver results in insecure attachment, wherein children lack confidence in relations with others
Disorganized pattern: Insecure Attachment style
Can be seen to be connected
Social Cognitive Model
The theory that dissociative identity disorder is a form of role-playing in which individuals come to construe themselves as possessing multiple selves and then begin to act in ways consistent with their or their therapist’s conception of the disorder.
-Diagnosed in adults and almost never during childhood
-represents a very different etiological position that is taken by many mental health professionals who do not accept DID as a legitimate disorder
