My grandmother atacked my then 4 year old son twice. Once with a large book and then with a pair of scissors. She was not provoked either. That is when I knew I could no longer care for her in my home. Alzheimer's is one of the most evil and vilest diseases out there.
My mom has encountered problems with patients before. They revert back to their childhood. If their childhood was violent, then it's likely the patient will act out. It's take real skill and talent to deal with them.
