How to get Mom to wear hearing aids?

Is she worried about the expense? Would she be willing to try a personal amplifier?
If it is vanity that is holding her back you might try pointing out that her deafness emphasises her age much more than hearing aids would.

With ALZ and Dementia it may not just be Moms hearing. It maybe how she processes. I found with Mom when you talked to her she was still trying to process the first couple of words and I was going onto something else. People with ALZ/ Dementia get overwhelmed in crowds. Like children, they get over stimulated.

Point out to her other aides she uses to maintain a level of independence. Glasses, dentures, wheelchair, walker, etc.

I deal with that problem as well. Extremely frustrating. My solution has been to (shout) at my husband to tell him that IF he wants me to answer him, talk to him, he MUST wear his hearing aids. If he doesn't, I won't. He doesn't like it, but it is HIS decision whether or not he wants a conversation with me. Don't make the mistake of taking on someone else's problem as yours. It isn't yours. It is hers. I realize that older people can become steadfast in their actions/reactions - my husband is 87. But stick with it. if you don't want to be confrontational, you could (shout) to advise your mom, that you will leave the room if she wants to talk to you without hearing aids. Even if she just puts them in for the short time you are talking with her, then takes them out again (they may bother her ears). Hope this helps. Remember, if you are to be there for HER, you have to take care of YOURSELF first.

Its hard for the elderly to wear hearing aides. Ur Mom has Dementia and its hard to do an eval if they can't follow directions or process. Then they won't wear them and have a hard time adjusting with the small wheels on the aide. As a person who has been married to a man who has had hearing problems since he was 4, even with a hearing aide Mom will have trouble in crowds. Its hard to concentrate on one conversation when more are going on around you. This is true for grandmom now. She needs to be in a small group of people with no background noise. Her and maybe two others. Each person looking at her when they talk. No talking over each other.

Has she worn hearing aids before? or does she refuse to wear the hearing aids she has now?

If so, the problem might be comfort. Mine -- the behind-the-ear kind, with a tiny cone on a clear wire all that goes into the ear -- came with cones that were too big for me, uncomfortable when in and almost impossible to get placed correctly. My audiologist replaced them with cones from a different brand. I wear 'tiniest possible' in one ear and 'only one size bigger than that' in the other.

I also notice a problem with manual dexterity. When my hands are stiff or trembling I have trouble getting them in right, and changing those tiny batteries can be a nightmare.

If they're adjusted too loud - say, because my hand trembled when I tried to adjust with those tiny controls - they're intolerable. The solution to that turned out to be a device I can wear on my belt or around my neck that has bigger buttons.

Hearing aids, no matter how good, can be unbearable in noisy environments.

There is a hearing amplifier that can be set on a nearly table or worn around the neck or in a pocket with a outlet for standard ear buds and head phones that can work better than hearing aids for many older people. They are about the size of a transistor radio. The switches are larger and easier to work and they can take the headphones off/on when they want. They are a lot less expensive than hearing aids too - only $30-50.

I am 81 and have been wearing hearing aids for almost 20 years. Not only are they expensive (although less so than 20 years ago), they are tiny, hard to keep up with, hard to manipulate, easy to lose and step on. The first ones I got were actually the best, but maybe that was because I was younger. They were molded to fit my ear and completely in the canal. And cost $5000 a pair, but I had a good job then. My hearing continues to go downhill, and the last pair of hearing aids I got 2 years ago at an audiology school are already not enough. They are behind the ear, and very easy to knock off if you are always putting your reading glasses on and off as I am. Still, not being able to hear your grandchildren is motivation enough for me.

Perhaps you could try making a written notice that says 'You cannot hear us and we cannot keep shouting. You must get a hearing aid. Then we can talk.' Get multiples made, and put one in front of her each time. She will cry a couple of times, but after that she may get it. Cuddle her and point at the notice.

I already answered once, but reading other replies made me think of something that I did not see mentioned. First, I did not mention that I too wear hearing aids. I do not hear high pitched sounds at all, or so faintly that I don't notice them. My most recent visit to the audiologist gave me some new information, It seems that there is more than one reason for hearing difficulties. One - the most prevalent one - is loss of volume of sound. But a really sneaky one is an inability to decipher sounds. My audiologist told me that the decoding function is not an ear problem, it is a function of the brain. There is NO fix for that malfunction. Sorry to say, that is my problem. I will hear a word like - mile. I hear the long I in the middle of the word, but not the beginning or end of it. So many words I miss whether wearing hearing aids or not. So, often I don't use them. If your mom has been diagnosed with loss of volume - has she also been diagnosed for deciphering words she hears? If that is her main problem wearing hearing aids will not make much difference. The other difficulty might be that they hurt/bother her ears when they are in. If that is the case, see if you can get her to wear them only when she wants a conversation with you. She might be up to using them if she doesn't have to keep them in all the time. Hope some of this - along with other advise given - helps. I live with both sides of that issue and it isn't fun.
