Imagine finding a glimmer of good news in a diagnosis of Alzheimer's. And imagine how that would change the outlook of the five million Americans who suffer from Alzheimer's disease and other dementias, not to mention their families, loved ones, and caretakers. A neurologist who's been specializing in dementia and memory loss for more than twenty years, Dr. Gayatri Devi rewrites the story of Alzheimer's by defining it as a spectrum disorder—like autism, Alzheimer's is a disease that affects different people differently. She encourages people who are worried about memory impairment to seek a diagnosis, because early treatment will enable doctors and caregivers to manage the disease more effectively through drugs and other therapies. Told through the stories of Dr. Devi's patients, The Spectrum of Hope is the kind of narrative medical writing that is gripping, humanizes the science, and offers equal parts practical advice and wisdom with skillful ease. But beyond the pleasures of great listening, it's a book that offers real hope.
