My mum has been in her lovely Nursing Home for 5 1/2 years, since her GP and SS said she needed 24hr care for dementia. She wanted to just be able to pass at that point, but that’s not how it works, obviously.
She has been so well looked after, but has recently really deteriorated. She apparently has an infection (not UTI) which may be the cause - GP to give meds as appropriate, but over a couple of days there was a sudden massive change and she isn’t really eating or drinking and is in bed and barely aware. It was really pitiful to see 
Does anyone have any idea of how long this stage may continue for?
