Definition: The inability to form memories for new information (as opposed to retrograde amnesia, which involves the inability to remember information previously stored in memory.)

Quite Simply...


  • After a tragic brain injury, someone with anterograde amnesia would only be able to remember things up to a certain point in time; anything after the event would be forgotten.
  • When a person is incapable of encoding and storing new memories, but is still able to retrieve old memories.
  • Not being able to form new memories or remember new information.
  • Only being able to remember things previously stored in long term memory.

Examples


  • A man who gets a head injury in a car accident and can only remember the events before the accident would have anterograde amnesia.Therefore, he can not remember new events that occur after the accident.
  • In the movie "50 First Dates", the girl could remember everything that had happened before her car accident, but couldn't remember anything that happened to her after that day.
  • The movie "Memento" where a man can't remember anything since his wife's murder so he must piece together the clues he finds by tattooing them on his body because he cannot store new memories.
  • The tragic case of H.M., who had his corpus callosum cut to cure his epilepsy. After parts of his amygdala and hippocampus were accidentally removed, he could only remember events that occurred before his operation. While he cannot form new declarative memories, he has demonstrated the ability to store new procedural memories.
  • In the beginning of Finding Nemo, Dori demonstrates anterograde amnesia when she keeps forgetting why Marvin is following her, even after he asked her multiple times for help finding Nemo.
