I live in the Southwest where there are cities with roads leading into the desert. From time to time we get stories on TV and in newspapers of families looking for their loved one who has Alzheimer's or Dementia and drove off in the car and can't be found. The afflicted loved will get into a car and drive off. Eventually the car is found way out on some road where they ran out of gas or the car malfunctioned and instead of staying on that road, they walk into the harsh desert and die (because of the impact of Alzheimer's or Dementia). Too many die in the desert. They're not found for a while. It's heartbreaking for the family and for everyone that hears about it on the TV and then much later ends up learning the fate. There's a story now of a man missing since June that had Alzheimer's for 8 years, demanded the car keys from his wife and she took them from the hiding place and gave them to him, and he has been missing since June when it was 105 degree heat and the heat only went up from there. Apparently his wife, like others, did not seek information on the ailment to know what to expect. So some organization is going to be a live chat about families, caregiving, wandering, etc. and maybe this will make a difference and save lives.
