My dad is in the moderate stage of vascular dementia and is quite hard of hearing, although it does seem to be somewhat selective at times. I got him hearing aids, but he didn't like them at all, so I stopped asking him to wear them. Something I would like input on is this: He invariably as me to repeat what I said, even if it is just yes or no. I try to give positive answers to his questions and say...."yes, that is a very good idea"......pardon? "yes!" - a typical exchange. He then gets huffy and says that I'm shouting and he never shouts at me, so why am I shouting at him. It makes my brain boil for a few minutes, so I go out of the room, then go back in again, by which time he has forgotten about it. Is there any good way for me to improve the situation?
