Alzheimer’s Disease and Music Engagement Economic Impact Analysis, an analysis undertaken by KPMG, estimates the economic impact of having people with Alzheimer’s disease engage with music. Based on its modeling assumptions, KPMG calculated a potential contribution of $830 million to GDP in the United States alone. In tackling that work, analysts developed a first-of-its-kind model that can be applied to many other art modalities, diseases, and outcome measures.
