Which of the following would be the first and most important sign of a serious head injury

Children and teens who show or report one or more of the signs and symptoms listed below, or simply say they just “don’t feel right” after a bump, blow, or jolt to the head or body, may have a concussion or more serious brain injury.

  • Can’t recall events prior to or after a hit or fall.
  • Appears dazed or stunned.
  • Forgets an instruction, is confused about an assignment or position, or is unsure of the game, score, or opponent.
  • Moves clumsily.
  • Answers questions slowly.
  • Loses consciousness (even briefly).
  • Shows mood, behavior, or personality changes.

  • Headache or “pressure” in head.
  • Nausea or vomiting.
  • Balance problems or dizziness, or double or blurry vision.
  • Bothered by light or noise.
  • Feeling sluggish, hazy, foggy, or groggy.
  • Confusion, or concentration or memory problems.
  • Just not “feeling right,” or “feeling down”.

Signs and symptoms generally show up soon after the injury. However, you may not know how serious the injury is at first and some symptoms may not show up for hours or days. For example, in the first few minutes your child or teen might be a little confused or a bit dazed, but an hour later your child might not be able to remember how he or she got hurt.

You should continue to check for signs of concussion right after the injury and a few days after the injury. If your child or teen’s concussion signs or symptoms get worse, you should take him or her to the emergency department right away.

A blow to the head may result in someone having pain or a headache. There may be a bump on their head and they may look pale.

1. Ask them to rest and apply something cold to the injury – for example, frozen vegetables wrapped in a tea towel. 

Applying something cold to the injury for up to 20 minutes will reduce external swelling and pain. When a person has a blow to the head, their brain can be shaken inside the skull as well. This may cause a more serious head injury which may make them feel sick or drowsy.

2. Call 999 if they become drowsy, repeatedly vomit or their condition gets worse.

This could be a sign of a serious injury to the head. If you can’t call 999, get someone else to do it.

3. Make sure someone responsible is able to look after them 

If the injury has happened when playing sports, they must not return to sport until they have been seen by a medical professional.  

Some people should always seek medical advice after a head injury because they are at greater risk. See the FAQ’s for more detail.
