It is not a matter that anything happens during sleep that would affect someone after a brain injury, instead the recommendation given to patients after receiving a blow to the head is to stay awake simply as a means of determining whether a serious injury has occurred. If a patient were to go to sleep, one could not assess the mental status changes that sometimes occur in a delayed fashion after a traumatic brain injury. cheers, gabriel vargas md/phd
