Alzheimer's can be tricky to diagnosed until it's blatantly obvious. To me it sounds like possible dementia but we can't know for sure since we can't "see" her. It may be that she is not getting enough oxygen in her blood to possible vascular issues. There are just so many factors that can be causing this. What sort of tests has she had already?
