I have read parts of the book. My husband refused to participate in ANY changes to his life years ago when I saw signs of memory issues. I think IF the person with dementia cooperates, there are really 32 holes in the roof that can be repaired. It is NOT an easy protocol to follow and everyone needs to be dedicated. That being said, I think if the genetic sequence is in action, no matter what we do, it will not change the course of the disease....
