I know there's a vast range of how dementia patients present in their varying stages, but how can it be that Mom fools virtually everyone other than family members? Upon her initial diagnosis, she missed almost all of the mini mental exam, and yet she can carry on a remarkably fluid conversation, only stumbling a bit here and there. I think she relies on a repetitious script for the most common topics. I listen to her all the time and everything she says is regurgitated over and over. Emotionally she's a bit more stable now that she's on full-dose Aricept and Namenda, but every once in awhile she goes off on a topic, something she's really upset about and you wish she would just shut up about it! You might have to hear about it for weeks and then she'll drop it for awhile and then pick it back up again days or weeks later. Memory-wise she cannot retain information much longer than 24 hours, often less, but the next day if you reference some one who visited her the day before, she'll make up some BS story. .She is unbelievably paranoid. She's convinced that all conversations she's not included in are about her. No one is as they seem. They are all conspiring against her. Someone is leaving the lights/TV/whatever on. Someone stole her hearing aids. Someone has been in her room (at MC) and rummaging through her stuff, even though the room looks completely undisturbed. She thinks I am stealing from her, taking advantage of her, etc,: doesn't confront me directly about my "crimes" but tells fantastic stories to everyone else she sees (and many believe them!!!!) She can still use her telephone but screws it up from time to time. (The cleaning ladies bumped one of the buttons. It's never Mom's fault. Mom is still remarkably neat and tidy and usually dresses appropriately, although I cannot say the same about her conduct. At 90 she still insists on getting her hair "done" and wears makeup every day. Sometimes she says the most outrageous things and lies like a rug. How can people who have known her for years not see this! Sorry for rant. Just blowing off steam.
