In everyday language, the book explains how Johns Hopkins scientists and the NIH showed that 30 million Americans with hearing loss have up to 500% higher risk of dementia (including Alzheimer’s) and falls with broken bones, and yet the vast majority (80%) don’t use hearing aids. It serves as a easy-to-use guidebook to overcome three obstacles (including Medicare policies), so that people can get hearing aids that work as well as advertised and that can dramatically reduce their risk of Alzheimer’s and the other major health issues. The information in this book is critical for advocates of improved US healthcare policy and insurers because Alzheimer’s care is costing American $230 billion/year and this will increase to $1 trillion in 7 years unless something is done soon.
