Define dissociation.
Segregation of any group of mental processes from the rest of someone’s physiological activity.
What are the 5 core symptoms of dissociative disorders?
- Amnesia
- Depersonalization
- Derealization
- Identity Confusion
- Identity Alteration
Define depersonalization.
Sense of detachment or disconnection from one’s self.
No longer personal.
Often described as stranger in one’s own body.
Feeling like you’re a robot or on autopilot.
Define derealization.
Sense of disconnection from familiar people or one’s surroundings.

Define identity confusion.
Inner struggle about one’s sense of self/identity
I don’t know who I am anymore
I don’t know which me is the real me
Define identity alteration.
Sense of acting like a different person some of the time.
Like split personalities
May use different names in different situations.
May have a learned skill without recollection of learning that ability.
What falls under dissociative disorders?
Dissociative amnesia
Depersonalization/Derealization disorder
Dissociative Identity Disorder
Define dissociative amnesia.
Potentially reversible memory impairment that primarily affects AUTObiographical memory (name, address, phone #).
Cannot recall personal info.
Define dissociative fugue.
Sudden unexpected travel or wandering in a dissociated state, with subsequent dissociative for the episode.
Subtype of dissociative amnesia
Usually occurs due to looking for the gaps in their memory.
When do we usually see dissociative amnesia?
Late adolescence/early adulthood
What is the diagnostic criteria for Dissociative Amnesia?
- Inability to recall important AUTObiographical information, usually of a traumatic or stressful nature, INCONSISTENT with ordinary forgetfulness.
- Significant distress/impairment in functioning
- Not caused by something else (Ex: Alzheimer’s)
- To add on dissociative fugue, must include purposeful travel or bewildered wandering associated with amnesia.
DX: Dissociative Amnesia w/ Dissociative fugue or just DA.
What are the 5 types of dissociative amnesia?
- Localized amnesia
- Continuous amnesia
- Generalized amnesia
- Selective amnesia
- Systematized amnesia
Systematized example: failure to rememer a category of info, such as all memories related to one’s family.
What is the treatment of choice in dissociative amnesia?
- Phase oriented psychotherapy (Standard of care)
- Cognitive therapy
- Hypnosis
- Group therapy
What is the role of meds in dissociative amnesia?
No use in standard treatment.
Benzos/amphetamines/barbs can be used to facilitate interviews.
What are the 3 phases in phase-oriented therapy?
- Stabilization and safety
- Work on traumatic memories
- Fusion, integration, resolution, and recovery
Fusion is combining 2+ psychological entities at a point in time, w/ subjective loss of all separateness.
How common is depersonalization/derealization disorder (DDD)?
Transient is more common, but it is generally rare in general.
1-3% lifetime prevalence.
What is the main risk factor and comorbidities for DDD?
Risk factor: Chronic trauma/stressor exposure
Depression and anxiety
What is the diagnostic criteria for DDD?
- Presence of persistent or recurrent experiences of depersonalization, derealization, or both
- Reality testing remains intact
- Causes distress
- Not due to a condition/mental disorder
What is reality testing?
If you ask a patient about reality, they answer appropriately still even while under derealization.
How is DDD treated?
Refractory to treatment often.
Psychotherapy often gives mixed results.
SSRIs may be helpful.
Define Dissociative Identity Disorder (DID).
Two or more distinct selves with distinct memories, thoughts, opinions, and goals.
What is the common demographic for DID?
Women
20s-30s
PTSD (MCC)
Childhood trauma (MCC risk factor)
What is the diagnostic criteria for DID?
- Presence of 2+ distinct identities or personality states.
- Amnesia must occur
- Distress/functional impairment
- Disturbance CANNOT be due to cultural/religious practices
- Syndrome is not due to other conditions
What are some signs that people may have DID?
- Referring to self in first (we) or third person (they)
- Depersonalized references
- Referring to parts of themselves by their roles (the wife, the angry one)
