Anterograde amnesia
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.
