Poor MIL has had Alzheimer's for about 14 years and is in the later stages. She is very difficult to deal with, doubly incontinent, often refuses food and drink for longer than you'd think survival possible. She's forever being pumped full of antibiotics to keep her going. I don't think she would have wanted this and I want to give my kids/healthcare providers power to decline the same for me if I ever get diagnosed with dementia. It would save the NHS a lot if there was a simple, free way to register your wishes, perhaps with your GP or the DWP and it were the norm to register your wishes. I'm not talking euthanasia here. I just think there must be an awful lot of families in our position with their loved one receiving treatment you doubt they would have wanted but because you're not sure, someone who might well believe it would be kinder to let them stay asleep rather than wake them up to ambulance them to hospital for drip and antibiotics has to treat them that way anyway. AIBU to think it should be the norm to register your wishes?
