"Wow - well, if alcohol prevents Alzheimers my "ex" will live to be about 999 years old."
Yes, but it does not prevent it. “Research has shown an association between drinking alcohol in moderation and having a lower risk for developing Alzheimer's disease.” This is from the website WG found.
I know its miss leading because of the BOOK title "Alzheimer's Prevention Program". (I am talking about the book not the website, but they are the same).
It's weird that that title says "Prevention" because when you read the book though, you will see that you can only slow Alzheimer's symptoms but never prevent it from happening.
Alzheimer's disease cannot be prevented yet.
