An aunt of mine, in her 80s with dementia, in a very nice care home, started refusing food and drink after the umpteenth UTI - she was always prone to them anyway.
As the only contactable relative at the time, I was asked whether we wanted her taken to hospital for drips, or left where she was, where they d keep her comfortable, but where she would almost certainly die.
Of course it was a horrible decision - I could only ask the lovely GP what he’d do if it were his much-loved aunt.
He said he’d leave her where she was, where they’d keep her comfortable. It was only going to happen again, probably quite soon.
I sat with her a lot during her last days. Her mouth was kept moist with those little sponges, but she continued to refuse food and drink - closing her mouth and turning her head away.
She was apparently asleep nearly all the time and drifted away after about a week.
Although I’d hated having to make the decision, I never once regretted it afterwards. I’m sure it’s what her pre dementia self would have wanted.
TBH hospital is a terrible place for anyone with dementia anyway, when they can’t understand what is going on, or why.
