Meanings for the term “dissociation” continue to evolve. Dissociation was originally seen as a type of hysteria, related to conversion, and distinct from depersonalization. It included amnesia, fugue, certain altered states (e.g., somnambulism), and multiple personality.
Dissociation is a criteria in DSM III for diagnosis of PTSD and ASD, as “flashback or dissociative episodes”. While flashbacks denotes sensing of something there that is not (positive symptoms), dissociative episodes denotes absence of sensing what is there –detachment, reduced awareness, derealization, depersonalization and amnesia (negative symptoms).
In Borderline Personality Disorder, dissociation in DSM-5 is described as “transient, stress-related…severe dissociative symptoms” with depersonalization as example.
3 distinct meanings of dissociative experiences (p.180):
- Dissociation of some of one’s mental functions or faculties. The DSM-5 definition: “a disruption of and/or discontinuity in the normal integration of consciousness, memory, identity, emotion, perception, body representation, motor control, and behavior” (p. 291). “Negative” dissociative symptoms involve the withdrawal of something, such as dissociation of memory (amnesia), sensation (conversion anesthesia), or affect (emotional blunting). “Positive” dissociative symptoms involve the intrusion of something, such as the sensory reexperiencing of a trauma (flashback), or any other intrusion of affect, knowledge, sensation (in any modality), or behavior (action, unintended vocalization, etc.). Most of these symptoms may occur within a single consciousness.
- Depersonalization/derealization. These may be experienced as the withdrawal of the sense of reality. These are also considered as intrusions in the DSM.
- Dissociative multiplicity. This is a plurality of consciousness, in which the first two types of dissociation commonly co-occur; thus, there is always the possibility that cases featuring the first two types of dissociation may have covert multiplicity as well. The DSM-5 definition does not really work for multiplicity because once there is more than one self occupying the center of consciousness, there is more than one center of subjective experience and consequently more than one set of symptoms.
Dissociation in Childhood Experience of Abuse
Freud and his colleague Josef Breuer (1895) identified the root of hysteria in women as child sexual abuse, specifically incest. Freud eventually reversed that emphasis to focus on a child’s fantasies of sex instead of the reality of sexual abuse. Other contemporaries—notably Pierre Janet (1889) outside the psychoanalytic movement, and Sandor Ferenczi (1949) within it—retained a focus on the trauma of childhood abuse, positing dissociation rather than repression as the main method a child (and later an adult) uses to cope. They observed that if the trauma were not worked through and resolved at some point, its residual effects would often have a lifelong (and negative) influence across various domains.

Dissociative effects of PTSD
Dissociation is PTSD is not psychosis. The person has a flashback — a momentary out of sync with reality, and reliving an experience in a traumatic past experience.
Dissociation is an altered state of consciousness. Unlike psychosis, the individual is functioning but loose track of time/space, etc. The persons may also have a sense of watching him/herself and not being there.
Dissociative effects from Childhood Neglect
The video above addresses dissociation from own feelings. This happens to children of child abuse from narcissistic parent. Most likely the condition of suffering is not unlike complex PTSD.
