This book is the first comprehensive overview on the molecular basis of Alzheimer's outside of the brain, merging the most recent findings within the field into a single book. It aims to educate the reader on the many overlooked aspects of Alzheimer's disease that occur outside the brain. It uniquely provides step-by-step, peer-reviewed evidence that the current research model may be misguided and that a new and emerging model is more accurate. It carefully outlines the molecular research in Alzheimer's outside the brain and argues that a more thorough, whole-body diagnosis will provide better answers about its causes and lead to new treatments. It is beneficial to researchers who need to be apprised of the emerging science on the causes of Alzheimer's, and will hopefully redirect many into new avenues of cellular research and discovery.
