PLIE (Preventing Loss of Independence Through Exercise) is a new program that combines elements of Eastern and Western traditional exercises and emphasizes focus on performing basic functional movements,encouraging social engagement and increasing bodily awareness. In the small group studied, patients would arrive at the exercise facility not remembering that they had been there but would start going through the movements of the routine. This fits with what we know about Alzheimer's : memory for events is impaired but procedural memory holds out and resists declination.
