@colleenyoung Thank you for pointing out the discussion on dementia and hearing aids. I will check it out.

N has had a couple of hearing tests and it is quite evident that hearing aids would be helpful. He is just stubborn about the situation. Part of it is admitting he is getting older (first test was done approx. 7 years ago, he is now 87), the expense although he can well afford the best quality, he worries that the size is so small he'd lose them (this is his latest excuse as he misplaces his glasses more frequently these days) and finally, the reason that bothers me the most) "I don't think I'm missing anything important." Oh, yes, you are! It has contributed to misunderstandings, confusion, frustrations for both of us. At his annual physical, his doctor complements him on his good physical condition which is true compared to many his age. I'm thinking of making an appt. for myself with his doctor to talk about N condition, hoping that the doctor will take my concerns more seriously and urge him to do something.
Thanks for asking and listening.
