Dissociative amnesia or functional amnesia, is a form of amnesia where there is an inability to recall information, usually about stressful or traumatic events in persons' lives, such as a violent attack or rape. The memory is stored in long term memory, but access to it is impaired because of psychological defense mechanisms. Persons retain the capacity to learn new information and there may be some later partial or complete recovery of memory.

This contrasts with e.g. anterograde amnesia caused by amnestics such as benzodiazepines or alcohol, where an experience was prevented from being transferred from temporary to permanent memory storage: it will never be recovered, because it was never stored in the first instance.

Dissociative amnesia is a dissociative psychiatric disorder that involves alterations in consciousness and identity. Its presentation varies considerably from individual to individual, but in most cases functional amnesia is preceded by physical or emotional trauma and occurs in association with some prior psychiatric history (Kritchevsky et al., 2004). Often, the patient is admitted to the hospital in a confused or frightened state. Memory for the past is lost, especially autobiographical memory and even personal identity. Semantic or factual information about the world is often preserved, though factual information about the patient’s life may be unavailable. Despite profound impairment in the ability to recall information about the past, the ability to learn new information is usually intact. The disorder sometimes clears and the lost memories return. Sometimes, the disorder lasts longer, and sizable pieces of the past remain unavailable.

In the usual process the pairing of emotion with an event seems to strengthen memory, so in dissociative amnesia other processes must be at work.
