I have just written some posts about exercise and diet which should have been in this forum.
My partner's mother has Alzheimer's and apart from helping where I can I have done a bit of research.
The official figures say 43% of Americans between 75 and 84 have Alzheimer's/dementia. I am 81.
It drops to 38% over 84 presumably because of deaths.
My partner who is a lot younger says she will push my wheelchair if necessary, change my toilet pads and feed me pureed food with a small spoon to reduce the possibility of pneumonia if it happens to me.
In Japan the figure is one in 17 Japanese, that is one in 17 of the total population. People are living longer and less babies are being born so the average age is rising sharply.
Exercise and eating properly aren't sure preventatives but they certainly reduce the risk !
More motivators to do the right things.
