Yes, dementia is scary. But in Canada, people are entitled to self-determination, meaning they are allowed to live at risk if they want to, as long as it doesn't put others at risk. Early in my nursing career, I worked part time in a home support position and there were a lot of elderly people living at home alone in filthy places, eating raw meat, and doing things you would never dream of. In BC, we also have a formal end of life planning process that all people are encouraged to fill out and register so their wishes are known. But it's still the person's wishes, not mine. So I guess my plan for when my parents are old and can't look after themselves is to go to the registry and implement their wishes. Either way, it's still not my plan; it's theirs. Even if it were verbal, it would be their plan. The OP says "What is your plan..." But I won't have a plan. It will always be my parents' plans.
