My husband was on a diuretic for mild raised blood pressure for years before dementia and GP instruction was to take it in the morning. When his blood pressure worsened he was prescribed other medication along with the diureic and took all his meds before his breakfast. With the exception of one tablet taken both morning and night. Then of course, with dementia and its progression, I had to attend to that for him. Plus the increasing bladder problems.
I would think taking a diuretic at bedtime not advisable.....
Some years after dementia my husband fell, fractured his hip, had surgery and in hospital his dementia worsened as did incontinence. Also his Type 2 diabetes. He was in 2 acute hospitals over 6 weeks - not good experiences with dementia. At home he had intermittent times of incontinence, but was fully aware of when he needed to go, just did not get there in time.
He was still aware in hospital and very anxious when he needed to go but then was incontinent because he forgot where the toilet was. Toileting by nurses was poor. He had pads put on and left to it, and began to lose awareness.
When later in the Community hospital over 4 months he improved, regained the ability to go to the toilet when he needed. Toileting was good, patients regularly prompted/taken to the toilet. But he had periods when he had to be got up once, even twice, during the night to be changed and washed (which he hated).
To cut a long story short, he was in hospitals six months as not allowed home. Everything gradually improved including incontinence after he went into the care/nursing home. The nurses on the dementia wing were great, and most of the carers they supervised. He regained the ability to go to the toilet when he needed, using a zimmer frame.
But as his dementia progressed his awareness lessened, incontinence worsened and was permanent. He was very wet overnight from neck to toes despite regular checks and was producing excessive urine overnight. So yes, dementa related and eventually double incontinence.
However with women ageing can weaken the bladder even when there is no dementia. Weakened pelvic muscles due to ageing, childbirth etc. Bouts of incontinence, a need to wear pads. Also men with enlarged prostrates. But they don't have the added dementia problem of not knowing when to go, or what to do....
The puppy sheets for the bed get a good name from carers who give home care, and they say they are as good as the more expensive ones. As cheaper, they can put two on the bed or overlap them to cover a wider area.
Just passing on what I have heard. Everyone with dementia can be different though, it can be trail and error can't it... Difficult at home as it becomes a 24/7 problem requiring constant supervision, plus the changing and washing of bedding and clothes. Not easy...
Good luck trying to find ways to deal with this difficult problem.
