Alan Alda investigates how people create memories -- and how as they age, memories become slippery and elusive, sometimes vanishing forever. He visits two men who live entirely in the present or the distant past, unable to recall events that happened even a few minutes ago. Viewers peer inside Alda's own brain and find out what's at work as he memorizes names and faces. Alda discovers how ice water can boost memory (no, not drinking it) and how easy it is to have a false memory implanted. He also meets a volunteer in an experimental treatment for Alzheimer's disease, gets the latest on the search for an Alzheimer's vaccine and joins a group of baby boomers who are learning how to keep their brains young and their memories intact. watch
