We can do little about some of the risk factors Dr. Roberts names--such as being female or being tall--but he provides lengthy lists of measures we CAN take to minimize our exposure to those things he believes can increase our chances of getting the disease. These include diet modification, tobacco, and remaining physically and mentally active in middle age. Particular emphasis is placed on the responsibility of physicians to "Think Alzheimers Disease!"...even if gross memory loss is not yet present, since early detection can maximize preventive efforts.
His book is about prevention of AD--an urgent appeal to people to prevent the development of full-blown AD by avoiding, as much as possible, the neurotoxins in our environment, by minimizing actions that enhance susceptibility, and by avoiding the neurotoxins in our processed foods.
