"In 2019, 5.8 million Americans had Alzheimer's, and more than half a million will die of Alzheimer's disease dementia. 16 million caregivers are responsible for paying as much as half of the $226 billion annual costs of their care. As more people live beyond their seventies and eighties, the number of patients will rise to an estimated 13.8 million by 2025. Part case studies, part meditation on the past, present, and future of the disease, [this book] traces Alzheimer's disease from its discovery and tells the story of the biomedical breakthroughs that may allow it to finally be prevented and treated by medicine"-- Provided by publisher.
