My mother was diagnosed with Alzheimer 10 yrs ago and has progressively gotten more docile and compliant. She didnt recognize me as her dtr but did recignize me as someone she trusted. Currently she is recovering from the flu and is now refusing to eat or drink - says she doesn't want to, doesn't need to and doesn't believe I know what I'm talking about.....trying not to take it personally, but she has a sinus infection and UTI that she will not recover from if she doesn't eat or drink more.....
Hope this helps. We got lucky that they tested for those things, bc I think they dropped from dehydration and if they had only given fluids, she'd still be in hospital I believe with no answers as to why she was so rapidly declining. Best wishes to you and your family
