My mom has vascular dementia and has not driven in 2 years. (She also had a below the knee amputation two years ago.) Lately, she gets into a loop of asking for keys and telling me I’m crazy and that she can drive and “just drove the other day”. She tells me I’m stupid and I want to take everything from her. We took her keys over two years ago but of course, she “remembers “ differently. Help! Every call/conversation ends in an argument.
