What you need to know about aging in place at home

Q. Two elderly gentlemen in their 80s live next door to us with no children and with no relatives or friends close by. They have substantial money and feel they will be OK staying at home. One of the men is showing signs of dementia; the other is unaware of future issues. Their home is a small 1920s home with a small bathroom, is not wheelchair accessible and there is no place for a ramp. I am concerned as a good neighbor and physical therapist. Could you write a column about assessing your living space and needs for the future?
