My Mom was diagnosed with Alzheimers 3 years ago or so. Her short term memory has been non existent for almost a year now, but her long term has always been pretty good. All of a sudden people that she knew from years ago that she has remembered she doesn't. For example she has always talked about some people that we know in Denver, haven't seen them in years but she gets a Christmas Card from them every year. She got one this year but could not place who they are. I know Mom will eventually forget who I am too, when it happens will it happen that quick?
