Thanks so much all of you
Been pondering (more like panicking) about all of this for a few days now and realised I've missed something completely obvious- the need for glasses to read/watch tv.
It's looking like it's going to be a fairly swift descend with the arms & hands. I am now panicking that Gran will not be able to watch TV/read a book because there aren't any carers in the home that have the time free to stay with her to help her do these things. Is she doomed to spend her days blankly staring out of the window until I eventually finish work each day to help her with these things?

So sorry for my (very bleak) outlook, but I am now entering panic-mode about all of this. I cannot bear the thought of her being utterly trapped without any mental stimulation, day after day.

Any thoughts on this?
