My father in law has dementia and he has started wandering. He will sometimes go out of hours and it isn’t usually concerning as he usually goes to the same place and usually comes back. However more recently he has gone further afield not returning and we have had to involve the police. I have heard about trackers for people with Alzheimer’s so you can see where they are when they are out and about but have no idea which one to purchase. Does anybody have any advice please? Thank you
