We've always been pretty good with the financial side of things, proper files of up to date paperwork for bank accounts, savings accounts, investments, pensions etc. and also had wills ever since we got married and bought our first home, which we've updated since, first time when DS was born and then again when he reached 18 years old, so hopefully we've covered things financially as far as we can for each other and ultimately our DS.
But we'd not really thought about the "care" side of things. Until a couple of years ago when MIL started going downhill rapidly with dementia. She'd been "forgetful" for a few years and we'd started to have to do more and more for her, but it was manageable, i.e. taking her shopping and to the bank every week etc. and visiting her daily (instead of previously a couple of times per week). We thought things would be OK if we just called in more often, did "complicated" things for her more often etc. At that time, things seemed pretty slow/steady and manageable.
She deteriorated amazingly quickly - almost getting worse by the day. Suddenly forget how to turn on the heating, and in fact, forgot she had heating, so we'd turn up and she'd be sat shivering. We had to start phoning her first thing every morning to talk her through turning on the heating! (She'd got into the habit of turning it off every night, which was an automatic habit she didn't think about!!). Then she'd mess up the TV tuning every time she turned it on - heaven knows how but she'd ring to say there was nothing on TV and we'd have to go down and found there were no channels tuned in, so we had to do the "auto retune" function almost every day. She'd previously been an avid enthusiastic gardener, but her garden became wild and overgrown - she'd keep saying she was going to do it "tomorrow" but never did. We got a gardener booked, told her about it daily beforehand, phoned her the morning he was due to arrive, but when he turned up, she threw him off the premises, shouting that she did it herself, etc - the guy phoned us from his van and we had to go down to pacify her and had to sit with her trying to get her mind of it whilst he did the garden. Same happened the following week, and every week afterwards.
Within maybe 6-8 weeks, she turned from someone needing a "bit of help" to someone completely incapable of being alone more than an hour. She'd do stupid things, like she had a bedside alarm clock which she'd had for years - red LED numbers. We noticed she'd started to turn it away from her in bed and we kept asking but she had no idea why she turned it. Eventually she remembered it was too bright, so that explained it. One night, around 3 am she phoned us in distress saying that there'd been a bang and flash and all her electric had gone off. We rushed around to find the electrics had tripped. We just reset it and things looked OK, so we settled her down and went home again. Next day, when tidying her bedroom, we noticed the alarm clock wasn't working - then we looked at the wire and she'd cut through it with a pair of scissors! She couldn't remember doing it, and couldn't understand why there were her big kitchen scissors in the bed! I think it was then that we realised she was dangerous being left alone.
Suddenly, things became very urgent - she couldn't deal with the bank and bills anymore, and we didn't have POA so we'd have to take her to the bank and luckily, it was a local branch where some of the staff had been there years so knew her and knew what she did with her "numerous" bank accounts where she seemed to transfer money between them for no obvious reason, but the bank staff just continued the pattern to appease her. Sometimes if someone she knew wasn't there, the other staff would just send us away as they could see she hadn't a clue and was incapable and weren't willing to do anything on our say so!
We tried to get a grasp of the finances, but there were piles of paperwork all over the house going back years, randomly placed in drawers, boxes, etc. no organisation at all, not even back a few years earlier when she was supposedly capable of looking after things. It took several full days to search the house and then organise through it all. We needed a handle on things as we realised the urgency of both financial and care POAs. Even if we got carers organised, we couldn't pay them out of her money as she had no internet banking set up. Those few weeks were an absolute nightmare. Sadly, her deterioration was so rapid, her health suffered too and she ended up with pneumonia and died within a few weeks (after an awful 3 days in a corridor in A&E!).
There'd been no time to organise carers nor POAs as the deterioration had been so quick. Then of course, we had to spend weeks decluttering her home before we could put it up for sale as it was full of a lifetime of possessions (plus what they inherited from their parents etc).
That made us re-evaluate ourselves and we've not set up care and financial POAs, we've also decluttered our home as far as possible, made lots of lists/notes etc. It made us realise that a will, whilst important, doesn't even begin to cover all the other aspects that serious/rapid ill health causes.
