We all have to put up with the trials of dementia. Our loved one's not undersatanding the simplist of things, having to repeat ourselves over and over again etc etc etc....its all part of the illness. My husband has Parkinson's and Lewy body. When he struggles to get off the chair or is slow moving, I can accept it is the Parkinson's and will help him. But when it is something that effects him mentally, such as telling me there are people in the room or he can't remember something I said 5 minutes ago, I go mad. I get so agitated and wound up and can't accept it is the illness. Just think he is a raving idiot. I've tried to see reason but somehow I can't. This just makes me an angry carer which does not help either of us. My husband has been ill 13 years(3 with LB) so I should have accepted it by now.
