My mother whom has vascular dementia refuses to allow anyone to come in to help in her home. She lives with her husband who is dealing with own health problems and at times is at wits end with her. He is committed to keep her at home as long as she remembers who he is. She can perform basic ADLs but does not cook. Can make toast and coffee. She has never had outside help and thinks that she is cleaning, laundering and cooking just fine. Gets very upset with me if I try to help. I think she feels we are criticizing her that she is not doing her "job". I try to get her to do it along with me but she thinks she just did it yesterday and that nothing is dirty. At times she has become very obstinate and verbally combative. She is very protective and clingy to her husband which has caused issues with his children. Any other suggestions?
