A blow to the head can cause a concussion in children and adolescents even when it leaves no visible mark. The outside can look fine while something inside has changed. The uncertainty that follows is the uncomfortable part, because acting too little and acting too much both carry a cost. What an adult does after the knock can shape how well a child recovers.
When a Knock to the Head Is Something More
Children bump and bang their heads often, and most of the time the result is a small lump or bruise that needs little more than a cuddle and an ice pack. A knock becomes something more when it reaches the brain inside the skull. A concussion is a mild traumatic brain injury, and a child’s brain is still developing. Most children recover, and that recovery depends on the right rest and care.
A concussion in children can happen with no loss of consciousness at all. This means a head knock can injure the brain while a child stays on their feet and keeps playing.
Signs and Symptoms of Concussion
The signs of concussion in children fall into a few groups, and a child may have some without the others. Physical signs are the most familiar: headache, dizziness, nausea, tiredness, blurred vision, poor balance, and sensitivity to light or noise.
Changes in thinking are easier to overlook. A child may seem confused or foggy, answer questions slowly, struggle to remember the fall, or find it hard to concentrate at school.
A concussion also affects mood and sleep. A child may turn more irritable, anxious, or tearful than is normal for them, and may sleep more or less than usual or have trouble settling.
When symptoms appear also varies. At the moment of the knock, a child might briefly lose consciousness, seem dazed, or have no memory of the fall, though a child may have none of these. Other symptoms of a concussion surface over the following hours or days, so a child who seems fine straight after a knock still needs watching.
First Aid for Concussions in Children
The first response to a suspected concussion in children is to stop the child’s activity and keep them out of any game, sport, or rough play. A second knock before the brain has recovered can cause far greater harm, so the child stays out even when they feel ready to keep going.
Stay with the child, keep them calm and still, and watch how they respond. Note whether they can answer you, whether they seem confused, and whether any symptoms are worsening, and do not leave a child with a suspected concussion alone in the first few hours.Some signs mean a child needs emergency care rather than home first aid, such as repeated vomiting, a seizure, or trouble staying awake. Give your child paracetamol for any headaches and avoid ibuprofen and aspirin.
Seek medical advice even when there are no emergency signs, because a concussion can only be confirmed by a doctor. A GP or health professional can examine the child, recognise whether it is a concussion, and guide the days that follow.
When to Go to the Emergency Department
A concussion in children can be managed at home, but some head injuries need emergency care straight away. Call an ambulance, or go to your nearest hospital emergency department, if a child shows any of these concussion symptoms:
loses consciousness, even briefly, or is hard to wake
has a seizure, fit, or twitching
grows more confused, drowsy, or less responsive as time passes
vomits more than once
has a severe headache, or one that keeps getting worse
has weakness, numbness, or tingling in an arm or leg
has slurred speech, blurred or double vision, or trouble with balance
bleeds or leaks clear fluid from an ear or the nose
complains of neck pain or tenderness
Treat the injury as an emergency from the outset when the knock comes from a car crash, a fall from higher than about a metre, or another high-speed impact, even before any symptoms appear. Some of these red flags take hours to develop, so a child sent home after a knock still needs watching across the first day or two.
Recovery and Return to Light Physical Activity
Recovery from concussion depends on rest. For the first 24 to 48 hours, a child needs plenty of sleep, less screen time, and a break from intense exercise and contact sport. Ordinary activities such as reading and short walks can continue, as long as any worsening of symptoms stays brief and mild.
After those first couple of days, a child can return to light physical activity, such as walking or gentle play, while symptoms keep improving. Activity steps up little by little, and each step holds for about a day before the next.
Return to school takes priority over return to sport. A gradual return to learning, with shorter days, rest breaks, or a lighter workload, lets a child keep up without overloading a recovering brain. A child returns to sport only after settling back into school without trouble.
Most children recover within several days, though a concussion in children can take up to four weeks to clear. A child should not return to sport for 21 days, and when signs of concussion remain at 21 days, they wait until every symptom has gone. When symptoms last beyond two weeks or grow worse, a child should visit a GP.
Be Ready Before the Next Head Injury Happens
An adult who stays calm and knows how to respond gives a recovering child the best chance. A child is safest around adults who have practised first aid for concussion in children before an emergency happens. Childcare first aid training gives those who look after children the ability to act in the first minutes after a knock, to tell an emergency apart from an injury that can be managed at home, and to respond without freezing. Your decision to enrol in childcare first aid training is what lets you meet the next head injury with the calm, correct response a child’s recovery depends on.
FAQs
What Are the Long-Term Effects of Concussions?
Most children recover fully and carry no long term effects. The lasting effects mostly come from repeated concussions: a prior concussion raises the risk of another, and recovery can take longer with each.
Can a Concussion Happen Without a Direct Hit to the Head?
Yes. A hard knock to a child’s body can jolt their head sharply enough to shake the brain and bring on a concussion. A heavy tackle, a fall onto the back, or a sudden whip of the neck in a car can each cause one, so a child can be concussed with no bump or mark on their head.
How Can I Lower a Child's Risk of Concussion in Sport?
In addition to using protective gear, warm-up routines build balance, coordination, and neck strength lower concussion rates when done several times a week.
