I think I’m about to answer my own question but it’s always clearer when I write it down and seek advice. Mum hasn’t had an official diagnosis because she refuses at every turn to go to the dr. But dr is aware of situation. So far she has been safe living alone. Able to cook clean and quite physically able. Things have changed and she now seems very confused about cooking. Mainly what needs to be cooked and how to do it. She can’t read / make sense of instructions anymore and is eating foods, which look cooked, raw ie pizza & battered fish (two of the things I know about) she didn’t know how to cook fresh veg & can’t make a cup of tea properly. I have done my best to put food in her fridge and freezer which won’t harm her if she eats then uncooked but worried about what she might buy (she shops most days...) i can’t decide whether she just gets flustered and out of her normal routine when I visit (now every 3weeks for a couple of days) or whether she really can’t cook now. She is very able with everything else personal hygiene, cleaning the house and walks everyday. But she has NOBODY to keep an eye on her on a daily basis. I live 3hrs away my sister 2hrs. Have we reached the point of daily care?
