My DH is in middle stage ALZ. I have become his safety net. He must know where I am and looks for me, even when I'm in the next room. If I go out alone, he calls quite often because he's frightened. We've had two situations when I was out he tried to use the microwave or put coffee in the toaster oven to heat in a non-oven dish. Fortunately he couldn't figure out how to use the toaster-oven but it was scary thinking of the possibility of a fire. Now I unplug the toaster-oven if I go out. He doesn't like my concerns about leaving him alone. I still leave him alone for short periods of time but when will I know for certain never to leave him alone?
