The person age 57 in 2013, normally has excellent long term memory including vivid details of events during early childhood. Also fairly good short term memory except when impared by hypoglycemia low blood glucose [glucose i brain fuel] and iron anemia possible cause of short term memory deficite. The unusual phenomenon about remembering a slightly different history is discovering that detailed memories of certain events in history do not match actual recordeed history. Nothing important or significant. Just little differences. Example, memory of subscribing to NOVA magazine of science and science fiction starting with its first issue January 1982, same month the novel 2010 Odyssey Two was published. Remembering both were boight together at same bookstore. After several issues, its name is changed to OMNI magazine. Of course it would be useful to have old copies of NOVA magazine to prove it actually happened that way. Recorded history shows the name was changed from NOVA to OMNI before the first issue was published in October 1978. Further, memory of reading an ad in that magazine in 1982 for the soon to be released movie Alien, the first one. The memory of reading in the magazine the ad about the movie while sitting at dining table in apartment in 1982. But history records that movie came out in 1979. The history difference spans 3 to 4 years. What could cause such a memory difference of history? What would the phenomenon be known as? Has anyone here heard of this happening to anyone? What might the cause be? What might the treatment be?
