early diagnosis global transient amnesia http://en.wikipedia.org/wiki/Transient_global_amnesia
Transient global amnesia (TGA) is a syndrome in clinical neurology whose key defining characteristic is a temporary but almost total disruption of short-term memory with a range of problems accessing older memories. A person in a state of TGA exhibits no other signs of impaired cognitive functioning but recalls only the last few moments of consciousness plus deeply encoded facts of the individualís past, such as his or her own name.
I think it directly relates to this
If the definition of a precipitating event is widened to include events days or weeks earlier, and to take in emotionally stressful burdens such as money worries, attending a funeral or exhaustion due to overwork or unusual childcare responsibilities, a large majority, over 80%, of TGA attacks are said to correlate with precipitating events.
