Bumps, knocks and falls are part of growing up, especially for junior sports players running around ovals and courts across the Mornington Peninsula every weekend. Most knocks to the head are minor, but every so often a child or teen takes a hit that affects the brain, and it is not always obvious straight away.
Concussion can look very different from one young person to the next, and symptoms can take hours or even a day or two to fully appear. Knowing what to look for helps parents, coaches and teachers respond calmly and appropriately, rather than waiting until something is clearly wrong.
What Actually Happens in a Concussion
A concussion is a type of mild traumatic brain injury caused by a knock to the head, or a forceful blow elsewhere on the body that jolts the head and brain. It does not require loss of consciousness to be serious, and in fact most concussions do not involve a “knock out”. The brain temporarily struggles to function normally, which is why symptoms can affect thinking, balance, mood and physical wellbeing all at once.
Recognised frameworks such as the AFL concussion guidelines and the Complete Concussions (CCMI) approach, which the team at The Seaside Osteo is trained in, emphasise that concussion is a clinical diagnosis. There is no single scan or test that confirms it on the spot, which is exactly why careful observation and follow-up assessment matter so much.
Common Physical Signs
Physical symptoms are often the first thing parents and coaches notice on the sideline. These can appear immediately or develop over the following hours.
- Headache or a feeling of pressure in the head
- Dizziness or balance problems
- Nausea or vomiting
- Sensitivity to light or noise
- Blurred or double vision
- Fatigue or feeling unusually tired
- Trouble sleeping, or sleeping much more than usual
A young athlete does not need to be knocked unconscious for these symptoms to indicate concussion. Even a seemingly minor collision during football, netball, basketball, cricket or football (soccer) can be enough to trigger them.
Cognitive and Emotional Changes
Concussion does not only affect the body. Many children and teens show changes in thinking and mood that can be mistaken for tiredness, distraction or “just being a teenager”.
- Feeling foggy, slow or “not quite right”
- Difficulty concentrating or remembering things
- Confusion about recent events, such as the score or what happened just before the knock
- Slowed reaction time or answering questions oddly
- Irritability, sadness, anxiousness or being more emotional than usual
Teachers often notice these signs before parents do, particularly when a student struggles to concentrate in class or seems unusually withdrawn in the days after an injury.
Why Younger Brains Need Extra Care
Children and adolescents are generally considered more vulnerable to the effects of concussion than adults, and their recovery timelines can differ. Their brains are still developing, and returning to sport, screens or full school workload too soon may prolong symptoms. This is one reason community clubs and schools around McCrae, Dromana, Rosebud and Rye are increasingly building concussion awareness into their return-to-play planning.
It is also worth remembering that symptoms are not always most severe straight after the incident. Some children seem fine initially, only to develop headaches, fatigue or concentration problems later that day or the next morning. This delayed presentation is a key reason to keep watching a child closely for 24 to 48 hours after any significant knock, even if they say they feel okay.
What to Do If You Suspect a Concussion
If a child or teen shows any of the signs above after a knock to the head or body, the safe approach is to remove them from play immediately. “If in doubt, sit them out” remains a central message across concussion guidelines, because continuing to play while symptomatic carries real risk.
From there, appropriate assessment supports safer decision-making about rest, return to school and eventual return to sport. This is where concussion testing on the Mornington Peninsula can help, giving families and coaches a structured, evidence-informed process to work through rather than guesswork. Our osteopaths are trained through Complete Concussions (CCMI) and use recognised assessment tools to help build a clearer picture of a young person’s presentation and guide next steps, always alongside appropriate medical care where needed.
Testing and clinical assessment do not prevent concussion from occurring, and no single test can guarantee a return to play is completely without risk. What structured assessment can do is support a more informed, staged approach to recovery, which is especially important for growing brains.
Building Awareness Across Local Clubs and Schools
Because concussion can be subtle, education matters as much as testing. Coaches who know the warning signs, parents who understand why “just shake it off” is not appropriate advice, and teachers who recognise concentration changes in the classroom all play a part in protecting young people.
For clubs, schools and community groups wanting to build this knowledge among staff, coaches or parents, our free concussion workshop covers recognition, response and return-to-play principles in plain language. It is a practical starting point for any junior sporting club on the Peninsula wanting to take concussion seriously without unnecessary alarm.
If your child has ongoing symptoms following a head knock, or you simply want a clearer understanding of related conditions, our page on the conditions we treat outlines how osteopathic care fits alongside broader concussion management.
Frequently asked questions
How soon after a knock can concussion symptoms appear in children?
Symptoms can appear immediately, but they often develop gradually over the following hours or even the next day. This is why children should be monitored closely for at least 24 to 48 hours after any significant knock to the head or body, even if they initially seem fine.
Does my child need to lose consciousness to have a concussion?
No. Most concussions do not involve loss of consciousness. Signs such as headache, dizziness, confusion, irritability or difficulty concentrating are far more common indicators and should never be dismissed just because a child stayed alert.
Should my child go straight back to school after a suspected concussion?
Not necessarily. Many children need a short period of relative rest followed by a gradual return to school activities, adjusted according to their symptoms. A staged approach, guided by appropriate assessment, generally supports a smoother recovery than rushing back.
What does concussion testing actually involve?
Concussion assessment typically includes a review of the injury history, symptom checklists, balance testing and cognitive screening, drawing on recognised frameworks such as Complete Concussions (CCMI). It supports informed decision-making about rest and return to activity rather than providing an instant diagnosis from a single test.
When should we see a health professional after a head knock?
Any child showing concussion signs, or who has taken a significant knock even without obvious symptoms, should be removed from play and assessed by an appropriate health professional. Seek urgent medical care immediately if there are red flag signs such as worsening headache, repeated vomiting, seizures or loss of consciousness.
