My mother has lost 95% of her short term memory; her long time memory is pretty good. She has developed severe incontinence, she sleeps a lot and tires very quickly. No mood swings and she has lost interest in many activities and is content to just sit and stare. We have gotten an aide each day to help get Mom ready for the day (1 1/2 hrs per day). Mom is 90 and my Dad is 92 and helping some, but he is not capable of doing much because he has mobility and processing issues himself.
