My uncle also has Alzheimer's. When I tell him I love him, he says it back to me because he knows he should, though I know he doesn't know who I am. It's a tough question. I believe his soul is still there. I can't say why I think this since his personality is just about gone. I don't think he's suffering. Maybe his soul is gone. He doesn't show any emotion or derive pleasure from anything. I guess he's not as far gone as your grandfather.

The best thing to do is believe that God is perfect. If you can have that trust in God, it'll get you through many tough times in your life.

I absolutely believe that sometimes God takes the souls before we know the person is gone. The Terri Schiavo case comes to mind. If I thought for a minute that her soul was still there, I would have been even more on the side of letting her body die.
