My dad is 88 and has been having mini-strokes which has caused moderate dementia. He also has had 2 major surgeries in 3 months, so for awhile he realized he couldn't drive, and let my sister drive him around. Now he forgets that the doctor told him he can't drive and he gets mad that we have taken the car away. He insists he can drive and is getting angry. Yesterday the car was there for a few hours, and he was demanding the keys and searching everywhere for them so he could show us he is capable. At times he can "pull himself together" enough to seem "ok", but other times he gets "lost" in his kitchen. He lives in the country with a full time aide who is afraid to have a car there, so my sister drives him to dr., etc. Now he is insisting that he will drive himself and is getting angry and upset. He is fiercely independent, "self-made" and controlling man. Can the police help? What can we do to make him understand that he could kill himself and innocent people if he gets behind the wheel of a car?? We are desperate for advice... Thanks in advance!
