Mom has mild dementia, 91 years old. When she doesn't like what I tell her to do she makes up stories and talks loudly over me or sings while I speak. I try to to get into her world and not argue but I become very frustrated. She tells me she is moving out or that she has a job lined up and she is leaving, LOL. My kids were never as fresh to me as she is. How do you handle this type of behavior?
