He has included caregiving to be his obligation. My other siblings and I have discovered abuse on his and his wife's part. We are going to confront him. But we know how arrogant he can be, because he has said this before to us; "I have POA for health." Please, please help. I'm so disturbed by his and his wife's action. They continually say Mom doesn't know better because of Alzheimer's. Mom is not in the advance stages yet. Thank you.
