"People with Alzheimer's Disease sometimes lose the ability to recognize familiar places, to communicate or to remember their own name or address.  They may leave home, become confused and get lost.  This can be dangerous for people with the disease and worrisome for caregivers.  But there is help.  Safely Home is a nationwide program designed to help find the person who is lost and assist in a safe return home.  Developed by the Alzheimer Society of Canada in partnership with the Royal Canadian Mounted Police, a registry stores vital information confidentially on a police database.  The information can be accessed by police anywhere in Canada and the United States."
