Alzheimers: Why So Many People Have It

Allan Gregg in Conversation (Video) show

Summary: David Shenk is the author of "The Forgetting: Alzheimer's, Portrait of an Epidemic". Shenk talks about this insidious disease, which, because of an ageing population, seems to be reaching epidemic proportions. There is still no known cause or cure although some drugs can mask some symptoms experienced in the early part of the disease. (Originally aired: November 2001)
