My mom has Parkinson’s dementia and last week began saying “help me” with every breath. We can ask her a question and she will answer it then goes right back to that phrase. It upsets everyone who visits her because they want to help her but there’s nothing we can do.
I would just give family and friends a heads up about what she's saying and to just try and ignore it as she doesn't really need help.
You might be able to find something that she can do that might keep her occupied so that she does not say "help me"
Does she like music? Can you put on songs she will sing to?
My Husband did not have a phrase he made noise and moaned.
Sometimes quietly other times very loudly.
I dealt with it by telling myself that I would miss it when he was gone.
I do..... sometimes.
there are medications that might help but medications with Parkinson's can be tricky.
Once, when he was lucid, I asked him why he kept asking for help. He said he didn't know, but we determined that he was comfortable and pain free.
It was destressing to hear him, but it felt easier knowing that he was okay. I hope this helps you to cope, too.
