Claim: Memento depicts the story of a man who has excellent memory.
Evidence: Pearce stars as a man who , as a result of a past trauma , suffers from anterograde amnesia , the inability to form new memories and suffers short-term memory loss approximately every five minutes.
Anterograde amnesia is a loss of the ability to create new memories after the event that caused the amnesia , leading to a partial or complete inability to recall the recent past , while long-term memories from before the event remain intact.
