Reputed Neurosurgeon Gupta has the ability to make complex medical matters simple. He explains things in layman's terms on TV and does so in this book also. "Keep Sharp" scared me at first because Gupta tells us that diseases like Alzheimer's begin in our brains decades before symptoms show up and there are really no effective treatments for them. However, the sub-title of the book "Build a Better Brain at Any Age," is reassuring and this is what we need to focus on. Gupta has some easy exercises, both physical and mental, to practice that he assures us will go a long way in managing dementia. Reading this book will definitely keep us sharp.
