My Mother is starting to lose her memory and repeating things over and over again. My brother lives with her but is having a difficult time stepping in and taking care of what needs to be done. She will agree to do things like calling a serviceman to fix something but when they arrive, she does not remember calling them and sends them away. She has always been a woman that has to be in control but her decisions lately are making no sense. My brother says he is having trouble stepping in to help. This is all new ground for us. How can we step in to help if she refuses to be helped?
