This is the best brain book I've read. It actually bases its findings on scientific evidence performed by the author and his partners in the field of medicine. Most other books usually focus on nutrition and brain games. This one promotes his brain training program based on his studies that the brain is plastic and can pretty much change up most maladies that befall our aging body...first and and foremost, an aging brain that forgets, can't track, and struggles in finding the right words in conversations, etc. People with brain injuries or other diseases can now find hope that all is not completely lost. One can recover some of the functions whether of limb or mind by devoting oneself to daily brain training exercises created by the author. The only downside to the book was the huge number of testimonials and studies one had to wade through to get to the salient point: brain training and its amazing benefits. Guess he really wanted to showcase the effectiveness of his program. To me, he's a genius!
