Tom, found these on another board so take it for what it is worth.
"Apparently he came round briefly this morning but he had very little brain acivity. They are now keeping him sedated and continuing tests."
"Serge seems a lot better. He is opening his eyes and responding to conversation by squeezing hands. He still can't speak yet, but lets hope he is now well on his way back."
"Latest is that Serge is OUT of the Coma and now breathing on his own. He still cannot talk and has only limited movement. He is showing some understanding of people talking to him. Hopefully he will make a full recovery but as yet there is still no news of any possible permanent damage."
