Hello my Dad is almost 80 years old and he has dementia I have been taking care of him for the past 10 years. I have MS and it is getting very hard. We both have good days and bad days. I need to know if there is any kind of medicine that I can get for him that will help him sleep and will also help his moods. He gets very angry at night. Sometimes it gets to the point that he starts screaming and slamming doors I dont know how much more I can take. Some one please help me.
