Head injury due to accident. Recovered.

It's been 14 days for the accident, at early he was not able to recognise the faces of his family members even, than after a week he started eating on his own as well he started doing daily activities & recognising some faces very quickly, sometimes words are like fumbling not easy to get but he is recognising now to some extent, he also remember the accident how & why it happened, he remember his job & started conversation regularly without stopping, it means he has all memories in his mind but not able to recall completely but I have a one question in my mind will he be able to fit as he was like before, & results are good as he is recovering, pls suggest what should be done now & how much time will more it take him to get recovered.
