<s>[INST] my Brother unfortunately faced an accident in 2011 December. had 2 surgeries in brain. his part of skull bone removed and now replace artificial bone. now he is in GCS 6 or 7.. can you explain how many years takes to his recovery???. now it is almost 2 years. have any special treatment, surgery for brain damaged patients, like he to improve his conscious level  ????? [/INST] Hi, it appears to be that he had his heifer functions impaired due to less blood supply, it has to be recovered by the improvement of the blood supply, The period taken will depend upon person to person. Only the time will decide the condition. If a major vessel is obstructed, surgical measures may be helpful. It appears to be the matter with the microcirculation, for these medicines are to be used and wait for the improvement. Thank you. </s>
