Over five million people in the United States have Alzheimer's and related disorders. That number will triple by 2050. Well over 50 percent of these people wander and become lost. A lost person with Alzheimer's or other dementia represents a critical emergency. They are unaware of their situation, they do not call out for help and do not respond to people calling out to them. Nearly half of them will die, and many can become injured or fall victim to predators if they are not located within 24 hours. If you are not yet touched in some way by Alzheimer's or a related disorder, chances are you will be within the next several years. You will find it among neighbors, your friends, co-workers, and perhaps within your own family. Project Lifesaver forms partnerships with local law enforcement and public safety organizations. Project Lifesaver deploys specially trained teams with the most reliable technology available to quickly locate and return wandering adults and children to their families and caregivers. Project Lifesaver, a nonprofit organization, has become internationally recognized as an aggressive and proven program that saves lives. It is not a registry system. It is an active response to the problem of locating wandering patients before they fall victim to the elements, accidents, or predators.
