Retrograde Amnesia

Retrograde Amnesia, also known as psychogenic amnesia or a psychogenic fugue, refers to the the loss of memory surrounding a physically or emotionally traumatic event and can be global (loss of all memories) or limited to memories specific to events that the victim might psychologically want to avoid remembering. This type of amnesia can be short-term and does not always include physical damage to the brain. This type of memory loss generally includes not only the event itself, but also events shortly before the event and generally includes both Episodic Memory (events) and Declarative Memory (knowledge), including autobiographical information.
