Does anyone else have a dementia parent that wants to use the restroom every 10 minutes?

What's common with dementia and incontinence is an urgency in feeling the need to urinate; the brain is sending fractured signals to the bladder as dementia worsens, so your mom may think she needs to pee when she she doesn't; or she feels the urge to go and only a drop or two comes out. Once you ELIMINATE a UTI which is easy to do via a urine culture (which could cause an increase in frequency to urinate), then make sure she's wearing incontinence briefs at all times. Get her on a schedule of going to the restroom every 2 hours.

I often say that if it wasn't for the need to use the toilet, elders lives would be SO MUCH easier in general, right? Both my parents were fixated with the toilet, and my mother would wind up falling off of it frequently as her dementia advanced, to the point where the caregivers would find her on the floor of the bathroom *in her Memory Care ALF* at least once a week. Thankfully she was checked on frequently, so she never laid on the floor for hours on end. Sigh. She too felt the need to go to the bathroom all the time, but she was wheelchair bound AND in Depends 24/7. Dad hated to actually urinate IN the Depends, so he was constantly wheeling himself back & forth to the toilet too.

I see you said mom isn't 'constipated', so is it BMs she is constantly feeling the need to have? You say she has dementia & mental health issues also, so that could be what's causing her this problem: psychological matters. If her medical scans are good, all you can do is give her more fiber to eat, but then she can wind up with diarrhea which is no good either. My 'uncle' George who's nearly 102 is on hospice and going thru this exact thing right now; but he hasn't had any tests to determine if he has a blockage. He's in the bathroom for hours on end 'trying' to have a BM but nothing happens. He eats very little, also. So there's no answer for him, either, sadly.

I hope this matter resolves itself b/c it's very frustrating for all concerned. There's nothing 'good' about dementia, let's face it, but there are situations that make you want to rip your hair out, I know. This sounds like one of them.

Agree with Geaton on that need to check re urinary problems. Have you asked Mom WHY she is going to the bathroom. There can be, in seniors, brain changes that signal to the senior that the bladder is full when in fact it is NOT. That is common. I am beginning, at 80 to notice those changes myself. At night will awaken thinking I need a bathroom trip, get there and think "That's IT???"
So ask your Mom if she is going because she feels constipated, or is she have some urine frequency. You can order plastic "hats" that you can put in the commode to check how much urine is being eliminated with these frequent trips. There are some medications that can lesson the urge to go if this is necessary. So I would continue of the medical workup. Get that U/A done. And if there's no problem there, discuss with Mom why so frequent on the trips, measure output and times for 24 hours, and then off to a Urologist.

Has she been checked for a UTI? Sometimes dementia impairs their ability to identify and/or express pain. In elderly women, UTIs are very common due to changes in physiology and pH, less to do with hygiene. Often there are no other symptoms other than changes in behavior, increased confusion, etc.
