Transient global amnesia is a rare condition that affects about five out 100,000 people per year. The experience can be frightening for both the person experiencing it and those who are present when it occurs. While experts have not identified a specific cause, some common triggers occur in people who have had transient global amnesia. Luckily, the condition resolves on its own within 24 hours and does not seem to have any long-lasting effects.
Transient global amnesia (TGA) is a temporary short term memory loss that occurs suddenly and is not caused by another neurological event such as a stroke or epilepsy. During an episode, the person becomes suddenly confused about where they are and what they are doing there. They may ask the same questions over and over because they cannot remember the answers they were just given. Otherwise, they are alert and seem to be thinking normally.
