She's always asking me if I hear it and I don't. What should I do and is this something I should take her to the doctor for? I think she has dementia, but the doctor doesn't think so. Her memory is getting very bad, she can't make decisions on her own, characters on her favorite soaps she doesn't remember at times. Is hearing music a part of dementia? Anyone? She's happy but this frustrates her and doesn't understand why this is happening.
At least she's hearing something agreeable!
Actually when my Mom complained about the talk radio she was hearing, I understood.... as late in the afternoon one of my landline phones will pick up a news station so you will hear it in the background while on the phone.
And many years ago, my police/fire scanner would do the same thing. Gosh decades ago I could hear telephone conversations if the person was using what was back then new technology, a cellphone [the phones were the size of a brick].
But I would seriously consider going to a different doctor as the one you mentioned doesn't seem very willing to explore alternate diagnoses. Perhaps a neurologist might help? I'll defer to those who have more experience with dementia diagnoses.
Personally I get crickets. They drive me crazy. I guess you can say that I have musical ears, but it is the music that crickets make. Ack!
It sounds to me like your mom needs a doctor who takes your reported symptoms seriously. I wonder if taking her to a geriatrician is called for at this point.
In general, hallucinations as part of dementia do not need to be treated unless they are disturbing to the person having them. You might say, "This is probably a medical condition that lets you enjoy the good music while I can't. I'm glad the music is good. Just enjoy it!"
