He was diagnosed with vascular dementia in May and since then he has fallen off the deep end. He is agitated 24/7, he hates my mother who is his caretaker and the sweetest person. He has been going psycho lately, he tried to punch her, thrown anything he could get his hands on and it has gotten to the point where I’m scared to leave her alone with him. I’m only 19 and don’t know how to handle this. He is so biligerent and mean. We want to get him into a home considering I have a 13 year old brother who my dad also hates. He tried to run him over with the lawn mower yesterday. Please help, since this started, I now have insomnia and am on anti anxiety medications. My dad also refuses to go to the doctor and they tried him on 3 different kinds of anti anxiety and depression medicines but they all made him worse. His speech is awful and we can barely understand him at all. If you have any suggestions please help because I am going insane.
