Alzheimer's Disease

With baby boomers entering their golden years, it's projected that the number of people in the United States with Alzheimer's disease will almost triple by 2050. Dr. Constantine Lyketsos, director of the Johns Hopkins Memory and Alzheimer's Treatment Center, provides the latest in Alzheimer's research, treatment and care. We're also joined by retired nurse Kellie Lynn, whose memoir "Our Long Goodbye" details her experiences as the primary caretaker for her husband, Bob, who died of Alzheimer's.
