About a month ago my mom started repeatedly shouting sentences “let’s go, let’s go” and one of my sibling's name nonstop–the only time she is not calling and shouting is when she is asleep at night. She has always been an active outdoor person, I typically walk her outside for 30 min every morning and take her on a 1 hour car ride every evening—all this to get her tired but nope. She is on lorazepam 1 mg a day but that doesn’t seem to be working. She is exhausted of the constant calling and shouting, and poor thing's throat and mouth dries up from it—is there a medication out there to keep her quiet and give me some rest from the constant calling?
My own mother used to call out also but it wasn't a constant thing and I could often figure out a way to stop it by going through a list of things that might be agitating her, I called it playing 20 questions - was she hungry? thirsty? needed repositioning? lonely? bored? in pain? needed changing?....??
For those times when nothing helps and it is getting on your nerves get yourself some earplugs. Seriously. Those foam ones from the drug store don't totally eliminate your ability to hear her but they will lower the volume, and sometimes that's enough to give you the ability to go calmly on with your day.
A change in behaviors (a month ago) should always be checked by a doctor.
If nothing seems to be working talk to the doctor there are other medications that can be used for anxiety. It might take a while and different doses.
If it helps, this is common with dementia. My Husband was not verbal but he did make a lot of noises some were quiet some very loud. But it was constant. I told myself at times when it was driving me crazy that someday I was going to miss that noise. And I do.
You can also try ear plugs, ear buds or headphones. As long as it is safe and you would be able to hear if there is a change in the noise or she were in trouble.
In general, many behavior modifying medications cause dry mouth. Have you told the prescribing physician that she’s had the problems with her mouth.
Unfortunately, you may have to wait this one out. The walks and rides and laundry folding and sorting activities are really good activities and certainly worth continuing.
Will she sing with you? If she’s willing to sing, maybe she’d try to match your voice as you sing softer.
If she’ll tolerate wearing ear muff style ear phones, you could try soft music going through them, in case she’s attempting to stimulate herself with her own noise, or even recordings of family voices reading stories.
Hope you find a solution.
