The most commonly used group of prescription drugs which can produce amnesia are benzodiazepines, especially if combined with alcohol, however, in limited quantities, triazolam (Halcion) is not associated with amnesia or memory impairment.
[40] Lacunar amnesia is the loss of memory about one specific event. It is a type of amnesia that leaves a lacuna (a gap) in the record of memory in the cortex region of the brain. The cause of this type of amnesia is the result of brain damage to the limbic system which control memories and emotions.
The attack lessens over a period of hours, with older memories returning first, and the repetitive fugue slowly lengthening so that the victim retains short-term memory for longer periods. This characteristic of TGA, where the length of time affected by retrograde amnesia shortens (i.e. older memories return first, followed by more recent ...

Recent studies have shown that there are multiple memory systems supported by discrete brain regions, and the acute effects of alcohol and learning and memory may result from alteration of the ...

Anterograde amnesia is one type of memory loss where people have difficulty forming new memories after the amnesia-causing event. Having a hard time remembering recent events? You may have a type ...
A person experiencing a TEA episode has very little short-term memory, so that there is profound difficulty remembering events in the past few minutes (anterograde amnesia), or of events in the hours before the onset of the attack, and even memories of important events in recent years may not be accessible during the amnestic event (retrograde amnesia).
