S.H.
That is what my late Dad had, exactly, before he died, and he also had a stroke.
My ideas are:
Doing things for him, around the house. BUT... to make him feel a part of it and still a "Man"... 'allow' him to suggest what needs fixing or what needs cleaning up etc.
Then, YOU hire a service, to do that for him.
Don't give food. Unless you know for SURE... that he CAN eat, what you give. Otherwise it will be detrimental to his condition.
Or, a large sized, tv remote control. My Dad had poor vision, so we got him a large sized remote, with large letters/numbers on it, so he could see.
Try Google Search it.
We found ours at Radio Shack.
Or, write him a nice note/poem, on how much you all love him and appreciate him. With a photo of you all. And then put it in a nice frame, for him. To display.
