Using Psychology to Aid Alzheimer's Patients

Fake bus stop keeps Alzheimer's patients from wandering off- The patients start to wander off, they see a bus station and stop to catch the bus.  Nursing home workers come by, tell them the bus won't be by for a while and invite them back inside for coffee and in a few minutes the Alzheimer patient forgets he ever was waiting for a bus.
