Alzheimer’s disease researchers are developing new techniques for identifying the disease much earlier than was possible in the past. This requires patients, families, and the medical community to talk about Alzheimer’s disease and dementia in different ways. Our guest Dr. Jason Karlawish joins us to discuss the evolving definitions of Alzheimer’s disease and dementia, as well as the ethical and social issues people with dementia face. Guest: Dr. Jason Karlawish, Penn Memory Center, Professor of Medicine, Medical Ethics and Health Policy, and Neurology at the University of Pennsylvania
