Hi doctor My bf is in coma from past two months. It was a case of severe tbi. Subdural hematoma. Gcs4-5. Pupil mild dilated. All other parameters like bp, wbc count etc normal. Responds to painful stimulation. He sometimes moves his head when his name is called. Sometimes water comes out of his eyes. His improvement is very slow. Im in long distance relationship so I don't have much information. I just want to ask you that can we predict by any test or something that when he will gain consciousness? And also will he go in vegetative state? Are there chances of his body impairment? thank you for your time doctor Please do the needful If you want any other document please let me, I really want him to be good soon. thank you again Anonymous.
