Symptoms may become noticeable only hours later, and concussion does not require loss of consciousness.

A fall or blow to the head may cause only a bump, but can also cause concussion, a skull fracture or bleeding. Symptoms may become noticeable only hours later, and concussion does not require loss of consciousness. Repeated vomiting, increasing drowsiness, a seizure, loss of neurological function or unequal pupils requires immediate emergency care.

  • Headache, dizziness, nausea, fatigue, blurred vision, tinnitus or sensitivity to light and sound.
  • Confusion, memory loss around the accident, slower answers, concentration problems or not feeling like yourself.
  • After a mild head injury has been assessed, have a reliable adult stay nearby and check for changes during the first day.
  • Sleep is allowed if the person responds normally and there are no warning signs; follow any specific waking instructions from the doctor.
  • Call the same day after a head injury with vomiting, persistent dizziness, memory loss, severe headache or worsening symptoms.
  • For urgent GP care outside normal opening hours, call HAP 9252. Call Ambulance 912 only for an immediately life-threatening situation.
  • Being unrousable, a seizure, repeated vomiting, increasing confusion, unequal pupils or new paralysis is an immediate emergency.
