I have A 94-year-old father who wears hearing aids. He complains that he can’t hear with the hearing aids. I have taken him back to the audiologist a number of times who will pair the hearing aids and then my father says he can hear. Then after a day or two he will say the one hearing aid is not working. I make sure that he has fresh batteries in the hearing aid when I go into see him daily. He told the nurse the other day he couldn’t hear with the hearing aids and she said when she took them out of his ears they were whistling and so they did have power in them But he says they’re not working. Other times he says everything is too loud with the hearing aids. I’m just wondering if the dementia is messing with his hearing capabilities. I have tried to research this but only find articles about people that are hard of hearing and how it can possibly make them a candidate for dementia.
