Ericks,
Rush and Consult the Doctors treating him and others with this GBS,from i think Dr.Zhivango below,it looks like it to me also even as a layman.
The problem with the very rare diseases (1 in 100,000) like this one is that they often get misdiagnosed as what now appears to be happening to your friend with them saying the nerves are dead.
I have read that up to 85% recover fully with proper treatment. Let the Doctors rule out this thing and don't listen to one doctor only,push around,consult other doctors as some don't like being corrected and time is moving,move fast.
I am a general consultant,specializing in all areas.
