While my mother is in the hospital, I am taking care of my father (95 years old). I work full time and have caregivers come in. He has gotten along with most of them but the last one he yelled at her to get out of the house and locked the door on her. She said she was afraid because he was very angry. My father has also been very angry at me. He yells at me, says he is going to punch me, and comes toward me in a threatening way. I contacted the doctor and told him about this increasingly disturbing behavior. He then prescribed some medication that can address this issue. My husband does not like my father's behavior and does not want him in the house anymore. I don't like the way his angry outbursts make me feel. It makes me sick. I know it is the disease, I know I should not take it personally and not engage with him. But his behavior is upsetting the harmony in my home. All the advice I read about not engaging when a dementia patient's rants and raves is not reality. This evening I wanted to visit my mother in the hospital and usually my father is willing to go with me, but this evening he yelled that he wasn't going and said he would punch me. I can't leave him alone so we didn't go. I was very disappointed that I couldn't see my mother. I can't make him do anything he doesn't want to do. I am very unhappy. What can I do?
