It sounds like the docs (and his wife) remain hopeful about his recovery. Maybe once they have him fully off the vent, he'll be able to speak; but it appears that he will have a tough physical therapy regimen to get back use of his right side. He's a very lucky guy to have a staff that acted quickly when he began to have symptoms.
Are you sure they acted quickly? The impression I had was they waited too long before calling the doctor.
