My mother has started this. She's in assisted living but had a UTI not long ago and it seems her dementia is much worse. She is under hospice care but gets around with a walker. She seems to not remember my daughter now and also has come out of her room with only one clothing item on, thankfully he nurse on duty turned her around and took her back to her room to finish dressing. She is nothing like this, she would never do that before the dementia took over. Did another UTI test and it was all negative so I guess there is no stopping this. She is almost 94 so I imagine we just have to accept the fact that this is the road to her end..
