I agree completely with Snowy. There are two major things involved with Alzheimer's care. One is medication, the other is the way you handle them or treat them as a person. You need to have both. A proper care attitude and proper medications. If either is lacking, then you are only asking for continued trouble. The key is to get a balance here, and get him more cooperative with his care and to make him more happy and give him a better quality of life. None of this will happen without proper care and medications.
I would think that a unit that specilises in the difficult care of Alzheimer's would know that. However, not all care facilities are created equal, and not all doctors either. You need to research and find both who are really specilists and reasonabily intelligent about both of his major care needs.
Sorry I can not be of much help. But, my mom who bite and kicked her physical therapist was much more cooperative when she was placed on the right drugs, and of course when her therapist was changed.
You have my sympathies, I've been there.

PS:On the practical side, be sure that you are at the nurses station every day asking questions. What meds is he on, how often, the dosage, and what is the drug for? Ask if they have spoken to the doctor about his problem behavior; is so. what was the directive, if not, why not? Question everything, if you do not notice an improvement in a few days, why? Can the drug be raised, lowered, substituted for another that works better.
I found that my role as daughter and advocate for my mother required me to take an active, even agressive role in the oversight of her care. I know that we are taught to behave, be quiet and trust the professionals. "Don't make waves". But sometimes it's only after the storm when we can enjoy the beautiful calm sunset and the open still blue sea. I have not only found that the "squeeky wheel gets the grease"; but that if your NOT willing to settle for less, often times you don't HAVE to.
