Head injury symptoms

Head injuries range in seriousness from very minor to life-threatening.

If you have a fit or seizure or fall unconscious, even if its only for a second, you should call triple zero (000) and ask for an ambulance.

If you are bleeding and it won’t stop, or if you have fluid coming from your nose or ears, you should go to your nearest emergency department immediately.

Even with a minor head injury, you can:

  • get a bump or bruise
  • feel sick
  • get a mild headache
  • become slightly dizzy.

Even in a mild head injury there is a small risk of you developing serious complications so you should be watched closely by another adult for 24 hours after the accident. If you show any of these symptoms or signs after your head injury, or you get worse, go to the nearest hospital, doctor or telephone an ambulance immediately.

  • Fainting or drowsiness - or you can’t wake up
  • Acting strange, saying things that do not make sense (change in behaviour)
  • A constant severe headache or a headache that gets worse
  • Vomiting or throwing up more than twice
  • Cannot remember new events, recognise people or places (increased confusion)
  • Pass out or have a blackout or a seizure (any jerking of the body or limbs)
  • Cannot move parts of your body or clumsiness
  • Blurred vision or slurred speech
  • Continual fluid or bleeding from the ear or nose
