Dad can't seem to shake this doom and gloom vision of the world. I try to change the subject, but he rounds back to the Depression, being poor, drafted, political situations long over etc... I try to focus him on other positive notes and he'll mock it or stay with it for a minute then right back to 1935, We're not poor, we have a nice home, he lives with us and has 24 hour care by family, regular doctor appointments, eats well... Other family will talk to him and he ignores them and leaves room. Any suggestions? He's at stage 6 Alzheimer's...
