The first volume of The Silver Book was launched in 2006 and has quickly become a trusted resource for health policy practitioners. The Silver Book®: Neurological Disease is the latest volume in this important collection. Each section in the volume includes charts, statistics, and key findings that together paint a comprehensive picture of the burden of neurological disease, focusing on Alzheimer's and Parkinson's diseases, and the tremendous potential of innovation. Much of the data focuses on the older population.
