Concussion in Children and Adolescents: What Parents Need to Know About Recovery, Return to Sport, and Nutrition
A modern evidence-based guide to helping young brains recover safely.
A knock to the head during soccer.
A collision on the rugby field.
A fall from a bike or scooter.
For many parents, these moments are followed by a worrying question:
"Could my child have a concussion?"
Concussion is one of the most common injuries affecting children and adolescents, particularly as participation in organised sport continues to grow. While most young people recover fully, how concussion is managed during the first few days and weeks can significantly influence recovery outcomes.
Fortunately, our understanding of concussion has evolved dramatically over the past decade. Gone are the days of prescribing complete bed rest in a dark room until symptoms disappear. Modern concussion management focuses on a carefully balanced approach involving relative rest, gradual return to learning, progressive exercise, and appropriate nutritional support.
Understanding what concussion is—and what it is not—can help parents make informed decisions and support their child's recovery with confidence.
What Exactly Is a Concussion?
A concussion is a mild traumatic brain injury that temporarily affects how the brain functions.
Importantly, concussion does not require a direct blow to the head.
It can occur when a force causes the brain to rapidly move within the skull, such as during:
Sporting collisions
Falls
Bicycle or scooter accidents
Motor vehicle accidents
Sudden whiplash-type injuries
Unlike a broken bone or torn ligament, concussion is primarily a functional injury rather than a structural one. This means standard CT scans and MRIs are often completely normal despite significant symptoms.
The injury occurs at a microscopic level, affecting brain cell communication, energy production, blood flow regulation, and nervous system function.
Recognising the Signs of Concussion
Symptoms can appear immediately or develop gradually over several hours.
Every child experiences concussion differently, which is why recognising a broad range of symptoms is important.
Physical Symptoms
Children may complain of:
Headaches
Dizziness
Feeling "off balance"
Nausea
Blurred vision
Sensitivity to light
Sensitivity to noise
Fatigue
Cognitive Symptoms
Parents and teachers may notice:
Difficulty concentrating
Slower processing speed
Brain fog
Memory difficulties
Reduced academic performance
Emotional Symptoms
Some children experience:
Irritability
Anxiety
Mood swings
Emotional sensitivity
Sleep Disturbances
Changes may include:
Sleeping more than usual
Difficulty falling asleep
Frequent waking
Feeling unrefreshed upon waking
Even mild symptoms should be taken seriously, particularly following a known head injury.
The Biggest Myth About Concussion Recovery
For many years, concussion management centred around one piece of advice:
"Rest until you're completely symptom-free."
While this approach was well-intentioned, research now shows that excessive rest may actually delay recovery for some individuals.
Current evidence suggests that the brain benefits from a gradual and guided return to normal activities rather than prolonged isolation.
Recovery is not about doing nothing.
Recovery is about doing the right amount at the right time.
The First 48 Hours: What Should Parents Do?
The first two days following a concussion are important for allowing the brain to begin recovering.
Current Australian recommendations focus on relative rest.
Relative rest means:
Avoiding strenuous physical activity
Limiting activities that significantly worsen symptoms
Prioritising hydration and nutrition
Maintaining regular sleep patterns
Reducing excessive screen exposure if it aggravates symptoms
However, children should not be confined to bed all day.
Gentle movement around the home, light conversation, and normal daily activities that do not provoke symptoms are generally encouraged.
This balanced approach helps prevent physical deconditioning while supporting recovery.
Why Returning to School Comes Before Returning to Sport
One of the most important principles in paediatric concussion management is:
Return to Learn Before Return to Play
The brain's primary job during childhood and adolescence is learning.
If a child cannot yet tolerate a full day of school, they are unlikely to be ready for competitive sport.
A structured Return to Learn program allows the brain to gradually rebuild cognitive capacity.
This process may begin with:
Short periods of reading
Brief homework tasks
Limited screen time
As symptoms improve, children can gradually increase:
Concentration demands
School attendance
Homework load
Classroom participation
Many schools now provide temporary accommodations such as reduced workloads, extra breaks, or modified assessment requirements to support recovery.
Returning to Sport Safely
For young athletes, the temptation to return to sport quickly can be enormous.
However, premature return to contact sport carries significant risks.
Australian concussion guidelines are among the most conservative globally and recommend:
A Minimum 21-Day Stand-Down Period
For children and adolescents under 19 years of age:
No same-day return to sport
No return to competitive contact sport for at least 21 days
Successful return to school before return to competition
Progression through a graduated exercise program
This approach significantly reduces the risk of repeat concussion and prolonged recovery.
The goal is not simply getting back onto the field as quickly as possible.
The goal is ensuring the developing brain has fully recovered before being exposed to further impacts.
Why Some Children Recover Quickly While Others Don't
Most children recover within several weeks.
However, recovery timelines vary considerably.
Factors that may influence recovery include:
Previous concussion history
Migraine history
Sleep quality
Anxiety or stress
Learning difficulties
Symptom severity
Age
Concussion recovery is rarely linear.
Many children experience good days and bad days before symptoms eventually settle.
This variability is normal and does not necessarily indicate a setback.
The Role of Nutrition in Concussion Recovery
Nutrition cannot magically cure a concussion.
However, the brain is one of the most metabolically active organs in the body, and appropriate nutrition may help create an optimal environment for recovery.
Think of nutrition as providing the building blocks the brain requires to heal and function efficiently.
Fuel the Brain Adequately
The brain consumes approximately 20% of the body's energy despite representing only a small proportion of total body weight.
Following a concussion, energy demands may increase.
Children who skip meals or under-fuel during recovery often report:
Increased headaches
Fatigue
Reduced concentration
Poorer mood
Consistent meals containing quality protein, healthy fats, and complex carbohydrates can help maintain stable energy levels throughout the day.
Omega-3 Fatty Acids: Supporting Brain Health
Omega-3 fatty acids, particularly DHA, are major structural components of brain tissue.
Emerging research suggests they may assist with:
Neuronal repair
Brain cell communication
Neuroplasticity
Inflammatory regulation
Excellent food sources include:
Salmon
Sardines
Mackerel
Trout
For children who consume little seafood, discussing supplementation with a qualified healthcare professional may be appropriate.
Prioritise Protein
Protein provides amino acids required for tissue repair and neurotransmitter production.
Including protein at each meal may help support recovery.
Good options include:
Eggs
Greek yoghurt
Lean meats
Chicken
Fish
Tofu
Legumes
For adolescent athletes, adequate protein intake becomes even more important when returning to physical activity.
Hydration Matters More Than Many Parents Realise
Even mild dehydration can worsen:
Headaches
Fatigue
Dizziness
Concentration difficulties
Encouraging regular water intake throughout the recovery process is a simple but often overlooked strategy.
A reusable water bottle and regular drinking habits can make a meaningful difference.
Antioxidant-Rich Foods
Following a concussion, a temporary inflammatory and oxidative stress response occurs within the brain.
While no specific food can eliminate this process, a diet rich in colourful fruits and vegetables may help support overall recovery.
Excellent choices include:
Blueberries
Strawberries
Raspberries
Spinach
Broccoli
Capsicum
Tomatoes
The goal is simple:
Eat the rainbow.
The greater the variety of colours, the broader the range of beneficial nutrients consumed.
Sleep: The Most Powerful Recovery Tool
While nutrition is important, sleep may be the most influential recovery factor of all.
During sleep, the brain:
Consolidates memories
Repairs cellular damage
Regulates inflammation
Restores energy reserves
Children recovering from concussion should aim for consistent sleep schedules and age-appropriate sleep durations.
Late-night gaming, excessive screen exposure, and irregular bedtimes can significantly slow recovery.
When Should Parents Seek Further Help?
Most children recover without complication.
However, further assessment is recommended if symptoms:
Persist beyond several weeks
Continue affecting school performance
Worsen over time
Interfere with normal daily activities
Cause ongoing mood or behavioural changes
Persistent symptoms often benefit from a multidisciplinary approach involving healthcare providers experienced in concussion management.
The Bottom Line
Concussion can be frightening for both children and parents, but modern evidence-based management has transformed how we approach recovery.
The best outcomes occur when children are supported through a gradual, structured recovery process that includes:
Relative rest during the first 24–48 hours
Early symptom-guided activity
Progressive return to learning
Graduated return to exercise
Appropriate nutrition and hydration
Quality sleep
Careful return-to-sport decision making
Most importantly, concussion recovery is not about complete inactivity.
It is about finding the right balance between rest and gradual re-engagement with life.
When managed appropriately, the vast majority of children and adolescents make a full recovery and safely return to school, sport, and the activities they love.
