I am facing this problem myself. My mom can barely walk but is too vain to use a walker or be around "old people" (she is 85). She lives in her messy home (she is too embarassed to bring in a cleaner and won't let her children throw anything away) and when she is upset she cries how her house is a mess. She talks of moving to an assisted living facility but, if her house is sold, that would leave no place for my alcoholic brother (who suffers like me, I believe, from PTSD; he may also be bipolar or manic depressive) to live. So, she continues to live at home. I am visiting on Monday to take her to the doctor. It's hard to get any real news out of her as she has really never liked me. She tells me what she wants me to hear and that's it. As for my alcoholic brother, he doesn't talk to me at all which is probably for the better. Still, at some point, something is going to have to be done.
