Young Athletes, Concussions, and the Nervous System: What Parents Need to Know
Why Some Kids Bounce Back After a Concussion While Others Struggle
One child is back to normal within a couple of weeks.
Another is still dealing with headaches, fatigue, difficulty concentrating, mood changes, and poor sleep months later.
Why?
While every concussion is unique, one of the most overlooked factors in recovery may be the health and adaptability of the nervous system itself.
At Healthy Families Chiropractic, we often explain that a concussion is not simply a head injury. It is a neurological event that affects how the brain and body communicate and function together.
Understanding the nervous system's role in concussion recovery can help parents better support their child through the healing process.
What Is a Concussion?
A concussion is a mild traumatic brain injury that occurs when a force causes the brain to move rapidly within the skull.
Concussions can occur during rugby, football, netball, hockey, cycling, gymnastics, mountain biking, skiing, or even everyday accidents and falls.
Importantly, a child does not need to lose consciousness to have a concussion.
Common symptoms may include:
Headaches
Dizziness
Nausea
Sensitivity to light or noise
Fatigue
Difficulty concentrating
Memory challenges
Mood changes
Sleep disturbances
Balance and coordination difficulties
While these symptoms often improve over time, some children experience ongoing challenges long after the initial injury.
A Concussion Is More Than a Head Injury
When a concussion occurs, the brain's ability to process information efficiently can become disrupted.
This can affect multiple systems throughout the body, including:
Balance and coordination
Focus and concentration
Sleep regulation
Emotional regulation
Reaction time
Recovery and adaptability
From a nervous system perspective, the goal is not simply to wait for symptoms to disappear. The goal is to support the brain and body as they restore healthy communication and regulation.
Why the Nervous System Matters
The autonomic nervous system controls many of the functions we don't consciously think about:
Heart rate
Breathing
Digestion
Sleep
Recovery
Stress responses
Following a concussion, some young athletes can experience changes in autonomic nervous system function.
Research has shown that altered heart rate variability (HRV), changes in autonomic regulation, and difficulties adapting to physical and mental stress can sometimes persist after a concussion.
This may help explain why some athletes continue to experience symptoms even after they appear physically recovered.
In simple terms, the nervous system may still be struggling to regulate and adapt efficiently.
Signs Your Child's Nervous System May Still Be Under Stress
Even after medical clearance, some young athletes continue to experience signs that their nervous system is working harder than it should.
Parents may notice:
Increased fatigue
Reduced stamina during training
Poor sleep
Heightened anxiety
Emotional ups and downs
Difficulty focusing at school
Slower recovery after exercise
Headaches triggered by physical or mental exertion
These symptoms do not necessarily mean something is seriously wrong, but they may indicate that the nervous system still needs time and support to recover.
Recovery Is About More Than Rest
Years ago, concussion management often focused primarily on complete rest.
Today, most concussion guidelines recognise that recovery is more complex.
Appropriately guided return-to-learn and return-to-play strategies are now considered important parts of recovery.
The nervous system benefits from the right amount of challenge at the right time.
Too much stress can aggravate symptoms.
Too little stimulation can sometimes slow adaptation and recovery.
Finding that balance is key.
Where Neurologically Focused Chiropractic Fits In
At Healthy Families Chiropractic, we do not diagnose or treat concussions.
Any child who experiences a concussion should be assessed and managed according to appropriate medical and sporting guidelines.
Our role is to evaluate how the nervous system is functioning and adapting during the recovery process.
Using INSiGHT scans, including Heart Rate Variability (HRV), we can assess patterns related to stress, regulation, and adaptability within the autonomic nervous system.
For some young athletes, these scans provide additional information about how their nervous system is coping with the demands of recovery, school, sport, and daily life.
Our focus is always on helping the brain and body communicate and adapt as efficiently as possible.
Looking Beyond Symptoms
One of the biggest challenges with concussion recovery is that symptoms do not always tell the whole story.
A child may say they feel fine but still struggle with concentration.
Another may be cleared to return to sport but continue experiencing poor sleep and fatigue.
This is why many practitioners now recognise the importance of looking at the whole picture, including neurological function, recovery capacity, stress levels, and overall resilience.
The Goal Is a Stronger, More Resilient Athlete
Every parent wants their child to enjoy sport safely.
Concussion recovery is not simply about getting back on the field as quickly as possible.
It is about ensuring the brain and nervous system have had the opportunity to recover, adapt, and build resilience.
When young athletes have a well-regulated nervous system, they are often better equipped to handle the physical, mental, and emotional demands of both sport and life.
If your child has experienced a concussion and you're concerned about their recovery, our team would love to help you better understand how their nervous system is functioning and whether additional support may be beneficial.
