I just finished watching Away from Her. It was a Canadian movie about a couple of 44 years dealing with the wife developing Alzheimer's. She decides to go into a nursing home. It was a rather slow moving movie but a nice love story nevertheless. It's nothing like "The Notebook," which is my favorite love story. I won't spoil the ending for you in case you decide to watch it.
It makes you wonder what you would do if your loved one had Alzheimer's. I worked with patients with Alzheimer's. At that time Alzheimer's was just being diagnoses. They were often diagnosed with dementia or something else before then . At that time there were no special wards or hospitals for them. The families took care of them or they were put into a nursing home.
I know I would take care of my loved ones whether they had Alzheimer's or anything to where they couldn't take care of themselves. Unless I couldn't absolutely take care of them I would.
