Dissociative amnesia is another dissociative disorder in which a significant, selective memory loss occurs. Dissociative amnesia is unlike simple amnesia, which involves an actual loss of information from memory, typically resulting from a physiological cause. In contrast, in cases of dissociative amnesia, the “forgotten” material is still present in memory – it simply cannot be recalled. The term repressed memories is sometimes used to describe the lost memories of people with dissociative amnesia.
