Are these all common aspects of Alzheimer's Stage 6 illness? My 84-year old mother with Alzheimer's Disease seems to be losing cognitive abilities in areas we used to help coach her along. She appears to be losing the ability to understand the meaning of different colors, which I first noticed in a button sorting game we do, then in coloring, and now with clothes. She seems to increasingly not understand the difference in colors. Her ability to dress herself (we lay everything out) is also becoming more difficult. This morning she had no idea how to put a shirt on. We used to watch TV, but now I see her eyes wandering vacantly into space. I ask her about the TV, but she doesn't even know where it is at, when it is right in front of her, she points to the window or the corner when I ask about the TV. Thank God she is still continent.
