Editing Repressed memory (section)

===Amnesia===
[[Amnesia]] is partial or complete loss of memory that goes beyond mere forgetting. Often it is temporary and involves only part of a person's experience. Amnesia is often caused by an injury to the brain, for instance after a blow to the head, and sometimes by psychological trauma. [[Anterograde amnesia]] is a failure to remember new experiences that occur after damage to the brain; [[retrograde amnesia]] is the loss of memories of events that occurred before a trauma or injury. [[Dissociative amnesia]] is defined in the [[DSM-5]] as the "inability to recall autobiographical information" that is (a) "traumatic or stressful in nature", (b) "inconsistent with ordinary forgetting", (c) "successfully stored", (d) involves a period of time when the patient is unable to recall the experience, (e) is not caused by a substance or neurological condition, and (f) is "always potentially reversible". McNally<ref name="pmid17803876" /> and others<ref name="Otgaar" /> have noted that this definition is essentially the same as the defining characteristics of memory repression, and that all of the reasons for questioning the reality of memory repression apply equally well to claims regarding dissociative amnesia.
