Hi, 3 years into my dads diagnosis, he’s becoming aggressive, and mum has her first bruise from him. He can’t remember these episodes later in the day, but it’s becoming more common on a daily basis where he talks down to my mum, nasty to her, accuses her of having an affair 20 years ago which isn’t true, he won’t allow my mum to tell anyone, she’s scared if he finds out she’s told me he’ll get angry with her, he’s starting to say terrible things in front of my children but sometimes he’s just back to normal with no problems at our wits end, I know he won’t go see anyone, won’t got to Docs’s etc
