Anterograde amnesia

From Academic Kids

Anterograde amnesia is a form of amnesia where new events are not transferred to long-term memory, so the sufferer will not be able to remember anything that occurs after the onset of this type of amnesia for more than a few moments.

Sufferers from "pure" anterograde amnesia will still be able to remember memories laid down before the onset of anterograde amnesia, but will exist in a transient world where anything beyond their immediate attention-span disappears permanently from their consciousness.

Damage to the hippocampus, fornix, or mammillary bodies can result in anterograde amnesia, suggesting that they are involved in the process of laying down long-term memories. A temporary form of anterograde amnesia is also induced by some medications, such as Versed (midazolam).

Steve Wozniak suffered from anterograde amnesia for approximately five weeks in 1981 following the crash of an ultralight plane he piloted.

A sufferer of anterograde amnesia is one of the patients profiled by Oliver Sacks in his book The Man Who Mistook His Wife for a Hat. In the book, the patient is called "The Lost Mariner": a man who began forgetting everything from the end of WWII. He does not even know that he suffers from amnesia and believes himself to be decades younger than he is.

Anterograde amnesia has also featured in fiction:
