TV shows are apparently going by the old myth that a person that suffered a concussion needs to remain awake. Pyth, this also answers why your parents were told to wake you occasionally.

It has long been thought that a person with a concussion should not sleep because they might slip into a coma or lose consciousness. Through research ... we now know that there is no need to make a patient with a concussion stay awake.

If the person who is injured is awake and holding a conversation, you can let him or her fall asleep as long as they are not developing any other symptoms such as dilated pupils or issues with walking. "Usually after a concussion, a person may be dazed or may vomit,” explains Dr. Alexander. “For children, we advise parents to wake up the child a couple times during the night to make sure they are able to be aroused."
