Jeffrey Kaye, MD, is the Director of the Layton Aging & Alzheimer's Disease Center at Oregon Health & Science University, where he is also a professor of neurology and biomedical engineering. Dr. Kaye joins us on the show to discuss the growing dementia epidemic. He’ll help us address frequently asked questions like these: How do we know if someone has dementia? Are there early signs? How does Alzheimer's progress? Are there treatments? We also discuss practicing healthy lifestyles that are showing promising results in easing the symptoms of dementia.
