Five million Americans suffer from Alzheimer’s disease and that number is expected to grow considerably with the aging population. But there is some good news. Recently there have been some promising new developments that could lead to advances in the diagnosis and the treatment of the disease. This hour, Marty sits down with two Alzheimer’s researchers to talk about the latest developments in the field. Our guests are JOHN TROJANOWSKI, Professor of Geriatric Medicine and Gerontology at University of Pennsylvania, Director of the Institute on Aging and Director of the NIA Alzheimer’s Disease Core Center and JASON KARLAWISH is an Associate Professor of Medicine and Medical Ethics at the University of Pennsylvania and Associate Director of the Penn Memory Center.
