amnesia is a condition in which one's memory is lost. The causes of amnesia have traditionally been divided into categories. Functional causes are psychological factors, such as mental disorder, post-traumatic stress or, in psychoanalytic terms, defense mechanisms.
Repressed memory refers to the inability to recall information, usually about stressful or traumatic events in persons' lives, such as a violent attack or rape. (From Wikipedia)
