Hmm.. not really clear cut for me. I would say 5/6with my dad.
His main problem is he has lost all sense of year, season etc. His immediate memory recall is virtually non existent at times (although he can learn new things - like, in the past week he has learnt where the cemetary is, and walks there easily with no help to my mum's grave (she was buried this Monday).
He is in total denial that he has anything wrong with him at all.
I cannot reason or justify anything to him. He talks utter nonsense at times - thinking he can go off and live where he did 20 years ago at the drop of a hat by just phoning the council and they will give him a place of his choice :-(
He also hides things he things are important (money etc.) and then can't find them! Ocassionally, he refers to peoploe 'wanting to do him in'.
But... he gets up, makes tea every day, makes something to eat (usually just a sandwich), dresses, showers (when reminded), remembers to shave, walks to the shops, buys milk etc and handles his money with no problem.
He sometimes gets our names confused, but on the whole is fine knowing his nearest and dearest.
He seems extreme in some areas, and mild in others.
This all confuses me so much.
