Head injuries and concussions

Adapted from the Royal Children's Hospital Fact Sheet Head injuries - General advice 

Children often bump or bang their heads. This can occur during sport, social activities, at work or at play. It is important that you advise the College by contacting Reception on 5233 9200 if your child has experienced a head injury so that we can work together to ensure their recovery and help them return to school.

Head injuries are classified as mild, moderate or severe. Many head injuries are mild, and simply result in a small lump or bruise. Mild head injuries can be managed at home, but if your child has received a moderate or severe injury to the head, they need to see a doctor.

Seek help immediately by calling an ambulance if:

• Your child has had a head injury involving high speeds or heights greater than a metre, for example, car crashes, high-speed skateboard accidents or falling from playground equipment.
• Your child loses consciousness (passes out).
• Your child seems unwell and vomits more than once after hitting their head.

Glossary of head injury terms

Concussion – a mild traumatic brain injury that alters the way the brain functions. Effects of concussion are usually temporary, but can include altered levels of consciousness, headaches, confusion, dizziness, memory loss of events surrounding the injury, and visual disturbance.

Loss of consciousness – when a person is unable to open their eyes, speak or follow commands. They have no awareness of stimulation from outside their body and cannot remember the immediate periods before and after the injury.

Signs and symptoms of head injury

The symptoms experienced straight after a head injury are used to determine how serious the injury is. The information below is a guideline. 

Moderate to severe head injury

If your child has a moderate or severe head injury, they may:

• lose consciousness
• be drowsy and not respond to your voice
• be dazed or shocked
• not cry straight after the knock to the head (younger children)
• be confused, have memory loss or loss of orientation about place, time or the people around them
• experience visual disturbance
• have unequally sized pupils or weakness in their arm or leg
• have something stuck in their head, or a cut causing bleeding that is difficult to stop, or a large bump or bruise on their head
• have a seizure, convulsion or fit
• vomit more than once.

You should call an ambulance immediately if your child has a moderate or severe head injury.

Mild head injury

A mild head injury or concussion is when your child:

• may display altered level of consciousness at the time of the injury
• is now alert and interacts with you
• may have vomited, but only once
• may have bruises or cuts on their head
• is otherwise normal.

You should seek medical advice if your child has any of the above symptoms of mild head injury, and you are worried about them. Otherwise, continue to observe your child for any of the signs and symptoms listed under care at home.

Care at home

Children and adolescents with concussion can take up to four weeks to recover, but most concussions will get better on their own over several days. Following a mild head injury, your child will need to get plenty of rest and sleep, particularly in the first 24 to 48 hours.

Your child may have a headache after a head injury. Give them paracetamol (not ibuprofen or aspirin) every six hours if needed to relieve pain.

There is no need to wake your child during the night unless you have been advised to do so by a doctor. Call an ambulance immediately if you have any difficulty waking your child.

Children who have had a head injury may develop symptoms at various times. Some of the symptoms may begin minutes or hours after the initial injury, while others may take days or weeks to show up.

If your child experiences any of the following symptoms, take them to the doctor or nearest hospital emergency department immediately:

• vomiting more than once
• bleeding or any discharge from the ear or nose
• fits/seizures/twitching/convulsions
• blurred or double vision
• poor coordination or clumsiness
• any new arm or leg weakness, or any existing weakness that gets worse or does not improve
• difficulty swallowing or coughing when eating or drinking
• sensitivity to noise
• slurred or unclear speech
• unusual or confused behaviour 
• severe or persistent headache that is not relieved by paracetamol.

If your child has had a head injury, they should return to school and sport gradually. For moderate to severe head injuries, your doctor will advise you. For advice on returning your child to their usual activities if they have had a mild head injury, see the Royal Children's Hospital fact sheet Head injury – return to school and sport and contact the College so that we can work together to ensure their recovery and help them return to school.
