I’m sorry to hear about your father. It’s really hard to watch our loved ones age, and it’s also really difficult when they have falls and hurt themselves. This can be a very frustrating time for the family and the patient. I understand this as I am a professional that works in physical rehabilitation.

The only way that he can be designated as not of sound mind is if a doctor has expressed it and/or there has been legal action with proof that he is not of sound mind. I don’t want to discount your feelings or thoughts as you try to communicate with him. Your feelings are yours and it’s absolutely okay to express them. This is just how it is- a doctor and/or legal action with proof. If this hasn’t happened and/or a doctor has expressed that your father has his faculties and is able to communicate to people with nods, etc as he does, then the doctor’s medical evaluation is what is followed. Now if you are concerned about any of this, then there is something that you can do. You can bring this to the attention of his immediate caregivers, a social worker, and/or his doctor. However, decisions of this nature are usually done with doctors, POA(s) if there are any, immediate caregivers, and/or an attorney depending on the situation. I do not know where you fall into these categories… You do not have to go into any more details as there is no need for me to know any more of his case or your personal details. And honestly, please don’t because internet/Reddit is not a place where I’m comfortable with any identifying information from anyone. But I wanted to convey that there are people that you can talk to if you feel that you need to express your concerns about your father and what is happening with him. I sincerely wish you and your family all the best.
