Slide 1-

Dissociative Disorders Dr. Kayj Nash Okine
Slide 2-

Dissociation A disruption in the normally integrated functions of identity, consciousness, memory, and perception Not due to the effects of a substance or a general medical condition Results in amnesia, depersonalization, and/or multiple personalities in the same individual
Slide 3-

Common Dissociative Experiences in Everyday Life Daydreaming Missing parts of conversations Vivid fantasizing Forgetting part of drive home Calling one number when intending to call another Driving to one place when intending to drive elsewhere Reading an entire page & not knowing what you read Not sure whether you’ve done something or only thought about doing it Seeing oneself as if looking at another person Remembering the past so vividly you seem to be reliving it Not sure if an event happened or was just a dream
Slide 4-

Possible Causes of Dissociation Fatigue Sleep deprivation Stress Binge drinking Drug use Confronting a new environment Feeling preoccupied or conflicted Engaging in certain religious or cultural rituals or events
Slide 5-

Making a Diagnosis Dissociative symptoms are only concerning when they become chronic and defining features of people’s lives Relevant clinical information for making a diagnosis: Quantity (frequency) & quality of dissociative experiences Cultural influences – are dissociative states accepted as part of religious or social experiences in a culture? Mood swings or changes Unexplained changes in handwriting Amnesia Episodes of unusual and uncharacteristic behavior Unexplained, sudden, extended trips Time distortions or lapses Erratic behavior Having 2 or more distinct identities or personalities
Slide 6-

The Dissociative Disorders Dissociative Amnesia: person forgets important personal facts, including personal identity, for no apparent organic cause Dissociative Fugue: person moves away and assumes a new identity with amnesia for previous identity Depersonalization: frequent episodes where person feels detached from their own mental state or body Dissociative Identity Disorder: formerly known as multiple personality disorder; characterized by disturbances in identity and memory
Slide 7-

Other Conditions With Dissociative Sx Substance Intoxication Psychosis Depression Personality Disorders Malingering
Slide 8-

Types of Amnesia Anterograde amnesia: the inability to form new memories after the condition producing the amnesia occurred; dissociative amnesia seldom involves anterograde amnesia Retrograde amnesia: loss of memory for events that occurred before the onset of the amnesia and the condition that caused it; dissociative amnesia usually involves retrograde amnesia for personal, rather than general, info Psychogenic Amnesia: amnesia due to a traumatic or extremely stressful event(s) Organic Amnesia: brain injury due to disease, drugs, accident, or surgery
Slide 9-

Dissociative Amnesia: Diagnostic Criteria 1 or more episodes of an inability to recall important personal information Can’t be attributed to ordinary forgetfulness Gaps in memory are most commonly related to a traumatic or extremely stressful event(s)
Slide 10-

Patterns of Dissociative Amnesia Localized: inability to remember all events occurring during a circumscribed period of time Selective: inability to remember specific events occurring during a circumscribed period of time Generalized: loss of memory encompasses everything, including one’s identity Continuous: inability to recall events subsequent to a specific point in time through the present Systematized: inability to recall memories related to a certain category of information, e.g. memories related to an individual’s father
Slide 11-

Etiology of Dissociative Amnesia Typically occurs following traumatic events: May involve motivated forgetting of traumatic events Poor storage of information during traumatic events due to overarousal Avoidance of emotions during traumatic events, as well as emotional reactions to the events afterward Dissociation during traumatic events Extreme life stress in the present
Slide 12-

Treatment for Dissociative Amnesia Goals: Help the person to remember forgotten or traumatic events in a controlled way & to accept & integrate them Resolve distressing situations Strengthen coping skills Interventions: Involvement of family member/significant other to remember what happened Trauma work Hypnosis
Slide 13-

Dissociative Fugue: Symptoms & Characteristics DSM-IV-TR criteria: person suddenly moves away from home and assumes a new identity, with little or no memory of one’s previous identity or past A person travels away from home abruptly and unexpectedly AND Is unable to recall some or all of his/her past Is confused about his/her identity (some disintegration of identity) May assume a partially or completely new identity May seem “normal” to people who don’t know him/her previously Prevalence: very rare – 0.2%
Slide 14-

Etiology of Dissociative Fugue Stressor or traumatic event (most common): person may be physically and mentally escaping a threatening environment or intolerable situation Chronic stress Depression
Slide 15-

Treatment of Dissociative Fugue Fugue states usually end rather abruptly on their own Following the episode, person may or may not recall events that took place during the fugue Supportive psychotherapy to help person identify & resolve stressors leading to fugue state and to learn better coping skills, so that fugue does not happen again
Slide 16-

Depersonalization Disorder: Characteristics 1 or more episodes of depersonalization Depersonalization: feeling detached or estranged from your thoughts or body; e.g. feeling like an outside observer, a robot; feeling like you’re in a dream, watching a movie Reality testing remains intact during periods of depersonalization Derealization: lose sense of external world; e.g. people seem mechanical or dead; things seem dreamlike, or seem to change size &/or shape
Slide 17-

Depersonalization Disorder Continued Occasional experiences of depersonalization are common - ½ of all adults have a single brief episode of depersonalization Sx must be so severe, persistent, and frequent that they cause significant distress or impairment in functioning
Slide 18-

Depersonalization Disorder: Research Findings Very little is known about this disorder and its treatment 50% have additional anxiety and mood disorders Demonstrated cognitive deficits on measures of attention, short-term memory, and spatial reasoning Demonstrated deficits in emotional responding: tendency to inhibit emotional expression; dysregulation in the HPA axis
Slide 19-

Dissociative Identity Disorder: Diagnostic Criteria Presence of 2 or more distinct identities or personalities At least 2 of these identities/personalities recurrently take control of person’s behavior Inability to recall important personal information that is too extensive to be explained by ordinary forgetfulness Disturbance is not due to the effects of a substance or a general medical condition
Slide 20-

Dissociative Identity Disorder: Characteristics 2 or more distinct identities or personalities (alters), each with its own pattern of perceiving, relating, and thinking, as well as unique behaviors, memories, relationships, and personal Hx Alters are often unaware of each other Transitions between alters (switches) are usually abrupt & are often triggered by stress or external cues Self-mutilation, post traumatic stress, conversion symptoms, & suicidal behaviors are common High incidence of comorbid psychological disorders, e.g. substance abuse, depression, anxiety, eating disorders, borderline personality disorder
Slide 21-

DID: Facts & Figures Prevalence: 0.5% -1.0% in nonclinical samples; 3-6% of severely disturbed inpatients Onset: almost always in childhood Gender Differences: 3-9x more frequent in women Women tend to have more identities than men (15 vs. 8) Course: tends to last a lifetime in the absence of Tx Age: frequency of switching may decrease with age Biological Correlates: demonstrated changes in optical functioning in alter identities
Slide 22-

Etiology of DID Alters are created under conditions of extreme childhood trauma, e.g. severe physical or sexual abuse Dissociation represents a natural tendency to escape from unbearable emotional or physical pain, a defense against extreme trauma Personality characteristics: suggestible, imaginative Lack of social support during or after the abuse Chaotic, non-supportive family environment Developmental window of vulnerability for DID closes at approximately 9 years of age
Slide 23-

Treatment of DID Goal: to integrate the alters into 1 coherent personality Identify each personality, and its function, roles, & concerns Negotiate with personalities to fuse into 1 personality Trauma work: identify cues/triggers that provoke memories of trauma &/or dissociation; neutralize emotional charge the memories hold via desensitization; reliving/re-experiencing Help person develop adaptive strategies for dealing with stress Use of hypnosis is common, but controversial Usually long term psychotherapy is indicated Antidepressants & antianxiety drugs may be used Do no harm! Don’t encourage disintegration!
