Wow this story is a bit terrifying, I can't imagine being trapped like that for so long with no way of communicating with people.
This story is amazing! I have always believed that this is possible. I worked in ICU and seen many people in this state. And I always talked to them and treated them with the thought that I knew some where in there they can hear and understand. This is just soooo good for the Medical world and also for all those in this fellas state, to give hope to family to help encourage action! God bless and the best of luck to the 46 year old.
