What is 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. Someone with anterograde amnesia will generally have good memory for the past, up until the time of the brain injury, but will have extreme difficulty remembering anything that has happened since then. Such a person may not be able to remember what he had for breakfast, what year it is, what he did yesterday, and so on. However, the person's personality, intelligence and judgement may be unaffected. This type of memory disorder is devastating for patients and for their families. Often, individuals with anterograde amnesia have trouble holding a job -- not because they are not capable of doing the work, but simply because they have trouble remembering from minute to minute what it is they are supposed to be doing. Currently, there is no known way to repair the brain damage which causes anterograde amnesia. However, the use of memory aids (such as detailed daily schedules) and other methods can help these people cope with their memory disorder. 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. |
