OK @OppsUpsSide I'll bite with your 'binning your parents into a care home' idea. Here's our story (shortened or you'll be here all day).
Mum developed Alzheimer's 6 years before she died. She was living in sheltered accommodation so had her own flat but with a communal area and warden on patrol.
We started off helping her with her shopping, then the cleaning as she forgot to change beds, clean toilets, wipe down surface in the kitchen. We got a cleaner (thanks to attendance allowance) which took some pressure off. Imagine going into your parent's home and finding a dirty loo and the kitchen surfaces sticky with tea/food etc., Short of going in every day you need a cleaner.
Then she started calling at 3am to say her diabetic nurse hadn't been (she used to come at 3pm but dementia often takes away the fact that there are 2 x 3 o'clock each day).
She had a heart condition, diabetes and kidney problems so one year I covered 27 separate appointments - on top of her dementia help.
She started having falls and ended up in hospital on a number of occasions. On one occasion she was on her kitchen floor from 9pm until 6am as she left her pendant alarm off!
We got her moved to an extra care facility - same as sheltered but with carers on site. They took over her medicine regime as she'd started taking warfarin and we found she'd left some in her poppet pill box or (worse) she'd taken two lots (plus) in one day as she'd forgotten what day it was. Even if we called her (four times a day) to remind her to take a tablet, she'd forget on her way to the tablet box or would remember twice and take two days worth.
Then, a few years ago, we discovered her putting her dinner in the oven at 9am. The carer would get her breakfast and do her dinner but would find meals 'missing' (she'd cooked them just after breakfast). As a diabetic she needed regular meals, not breakfast immediately followed by dinner and then a gap til a sandwich at lunch time. We then got the equivalent of meals on wheels for her so she didn't have to worry about cooking and there wouldn't be food in the fridge to cook. The carer would do breakfast and make her a sandwich in the evening as she had her hot meal delivered mid day.
The 3am calls continued then she took to wandering and was found heading for the main doors in her flats by a carer - it was 4.30am and a main road was outside...
Then she had a massive collapse. I was there and she literally couldn't move her feet. I got her to the floor, ambulance arrived and she never went back.
She was assessed in hospital as needing respite care but the respite people said she needed 24/7 care as she was, by then, tripping up regularly. She then began to lose control of her bowels but would try to clean herself up - with bare hands...(often happens with Alzheimer's).
So a decision was made to find a care home and she moved into one. The change was amazing. She had company, 3 regular meals plus snacks. They put her on a diabetic safe diet so her diabetes came back under control. She had a number of falls but instead of me having to rush round to her flat they called paramedics or got her back to bed as they were trained to assess her. When I was getting calls for falls I would either be leaving DS who was at junior school with DH who would have to call into work to say he'd be late so he could get DS to school or, on more than one occasion, I had to leave DS to be picked up from school by a friend as DH was working 600 plus miles away at one time. He'd have to fly home as I'd often be in A&E for 12 hours plus then on a ward trying to settle her.
When mum was in the care home she continued with the bowel problems (we'd often have to summon help to get her clean as she'd use her hands to wipe her bottom, smear the poo on the walls, drop it on the floor then step in it). I'm telling you this so you can see dementia doesn't always mean a lovely little old lady who can't remember certain things. It affects everything from swallowing to toileting, movement to temperament.
The care home saved my sanity and gave me a couple of precious years of actually sitting with my mum chatting over a cup of tea instead of checking medications, shopping, cleaning, laundry, hospital appointments and the dreaded phone call in the early hours.
Don't knock care homes or those who use them until you've walked in their shoes.
