Hello @joseph1956,
A couple of years ago I helped a friend write a book about her experience with Alzheimer's Disease. She published the book and included resources for those struggling with this disease. Then she sold the book at cost, without profit.
My friend did not have Alzheimer's. Her husband did. They had a marriage that lasted many decades, and he stayed with her until almost the very end. Only hours before he died did she allow hospice to take charge of his care and ease his passing.
I found your portrayal to be sensitive and spot on. My friend's husband was there, and not there. He was aware of deficits, and that awareness seemed to bring him his greatest distress. I think his decline was less precipitous than it might have been because she kept him home (with professional help) and in familiar surroundings.
Can't tell you how impressed I am with your story.
