The Alzheimer's Association has a new tool to help families keep track of their loved ones.

It's designed to prevent patients from wandering, which about 60 percent of Alzheimer's patients do at some point.

The group's new "Comfort Zone" system uses a transmitter and a web-based mapping system. Families get a text message or an email if their loved ones leave a virtual perimeter zone.

The system could prevent accidents among the five million Americans who have Alzheimer's disease.
