Alzheimer's

oh my heavens, our extended family is beginning to realize that in spite of all of the awesomeness that exists in our lives it is time to accept that Alzheimer's is now touching us and we need to find a way to deal with it. My grandmother was killed in a car accident when I was 13 and my grandfather remarried a year later to the woman who is now his wife. My grandfather is having major heart and lung problems which just forced them to come home from Arizona. We have been suspecting but now realize that the extremely beligerant behavior that his wife has exhibited over the last 2 years was the beginning of Alzheimer's. My parents went to pick them up in AZ ... and there is no question there is a major problem that must be dealt with immediately - she is so bad she is threatening the welfare of my grandfather. Not a good situation!
