What is dissociative amnesia?
Dissociative amnesia is a disorder in which the distinctive feature is the patient's inability to remember important personal information to a degree that cannot be explained by normal forgetfulness. In many cases, it is a reaction to a traumatic
accident or witnessing a violent crime. Patients with dissociative amnesia may develop depersonalization or trance states as part of the disorder, but they do not experience a change in identity.
Dissociative amnesia is characterized by a blocking out of critical personal information, usually of a traumatic or stressful nature. Dissociative amnesia, unlike other types of amnesia, does not result from other medical trauma (e.g. a blow to the head). Dissociative amnesia has several subtypes. Localized amnesia is present in an individual who has no memory of specific events that took place, usually traumatic. The loss of memory is localized with a specific window of time. For example, a survivor of a car wreck who has no memory of the experience until two days later is experiencing localized amnesia. Selective amnesia happens when a person can recall only small parts of events that took place in a defined period of time. For example, an abuse victim may recall only some parts of the series of events around the abuse. Generalized amnesia is diagnosed when a person's amnesia encompasses his or her entire life. Systematized amnesia is characterized by a loss of memory for a specific category of information. A person with this disorder might, for example, be missing all memories about one specific family member.
