Supporting New Zealanders Living With Brain Injury


A concussion, also known as a mild traumatic brain injury, occurs from a blow to the head or violent shaking. It is a very common injury in New Zealand, with approximately 24,000 cases every year.

  • Signs to watch for
    Problems could arise over the first 24 hours. You must go to the hospital if you:

    • ∑ Have a headache that gets worse
    • ∑ Are very drowsy or canít be woken up
    • ∑ Canít recognise people or places
    • ∑ Pass out or have a blackout
    • ∑ Vomit more than 3 times
    • ∑ Behave unusually or seem confused
    • ∑ Have seizures
    • ∑ Have weak arms or legs, or are unsteady on your feet
    • ∑ Slurred speech
  • The person looking after you needs to get you straight to the hospital or call 111 if they notice any of the above symptoms. Donít hesitate Ė remember, it is better to be safe.
  • Sleeping
    It is important not to go to sleep in the first 4 hours. After that, a normal nightís sleep is needed, at the normal time. If sleep seems strange in any way, the person looking after you needs to know to rouse you until you can say a word or two, then let you go back to sleep.

    If there is any worry about the severity of the blow, it is safest on the first night to gently rouse the sleeper every 2 hours during the night, and ask them to answer to simple questions. If a person cannot be woken normally, then medical help must be sought.

    Do not drink alcohol or take sleeping pills for at least 48 hours.

    Do not drive for at least 24 hours. You can drive again when you stop feeling giddy and you feel well enough; if you have any concerns, talk to your doctor.

    Pain relief
    It is safe to take paracetamol for the headache. Donít take medication containing aspirin or dispirin for the next 4 days. This type of of medicine can make you bleed more from cuts and bruises.

    Returning to sport
    You must stand down from sport for at least 3 weeks AND you should not return to sport or training until you are symptom free AND have medical clearance. That way youíll return 100% ready for play.


    • ∑ Repeated concussions have a cumulative effect, so if you keep having concussions you may end up with a more serious injury and a permanent disability.
    • ∑ Second Impact Syndrome Ė acute brain swelling and bleeding that occurs when a second concussion is sustained before the first one has healed properly. This can be difficult to treat, and can be fatal.
