My mother , who is now deceased, first showed signs of Alzheimers in late 1995. In 1996 my dad passed away and it became clear she needed help. The hospital in a larger city about 25 miles from her town operates a monitoring service for patients like her. She had a monitor on a necklace which she could push if she got into trouble. Also there was a monitor in her house and they checked on her everyday. Later in 1997 I saw a drawback to having a monitor on you if you are an Alzheimer's patient. You forget what it's for. But, it still gave me a greater sense of security knowing this was in her house and on her person.
