My cousin a week and a half was unconscious for about 2 hour he's a diabetic and where he was at could not get him to wake up so 911 was called at first the drs., said he had 2 major strokes then they said he didnt. Check menegiti s, they say now he had a seizure, put don't know how much brain damage he had about 3 days ago he woke up but he still does not talk or follow commands, can a seizure do this and what are prognosis?
