Transient Global Amnesia
=====================
Transient global amnesia is a sudden, temporary episode of memory loss that can't be attributed to a more common neurological condition, such as epilepsy or stroke.
The individual, as the name suggests, is in a temporary state of amnesia, where they can only recall stronger, long term memories such as:
- Who they are
- Where they are from
- Their relatives and friends
They may not remember:
- Where they are
- Why they are here
- How they got here
- Some events from a day, month or even a year ago.
This peculiar pathology has a sudden onset and lasts on average 4-6 hours, although it can get to extend up to 24 hours. At the end of the episode, the person fully recovers his neurological functions, but a "black hole" of a few hours is left, corresponding to the time frame in which he was unable to form new memories.
