Free online book about Alzheimers

This book is a very in-depth look at Alzheimers disease including the genetic component and concrete ideas for preventing it.

A second cousin of mine had her mother and most of her aunts and uncles succumb to Alzheimers. My mother at 91 is still pretty sharp, and I'm related to this cousin on my mother's side of the family, so hopefully I don't have the Alzheimers genes, but you can still get it even if you are not genetically pre-disposed.
