From your accounts I would say that palcing your mother in hospital care is probably the best move for you, your family and your mother. Especially if she is dangerous to herself and others. From the little information you have given, it sounds like your mother is undergoing a psychotic episode. With rest and medication she may be able to start dealing with the causes of the episode.
Patience and strength my friend, you are going to need them. These issues take time to sort out. I sincerely hope your mother is better now that she has rested and received some professional help.
