The American Academy of Pediatrics (AAP) has released an updated clinical report titled “Sport-Related Concussion in Children and Adolescents” (2023), offering critical new insights on diagnosis, treatment, and prevention of concussions in youth sports. This update builds on the original 2010 guidance, reflecting over a decade of research and evolving clinical practices.
Below is a breakdown of the most significant and evidence-based takeaways from the AAP report and related current literature, with an emphasis on actionable guidance for parents, coaches, and healthcare providers.
Understanding Concussions: Beyond a Simple “Bump on the Head”
Concussions are complex neurometabolic injuries caused by biomechanical forces such as a direct hit or whiplash-like motion. These forces disrupt normal brain cell function, triggering a cascade of metabolic changes—like potassium ion shifts, glutamate release, and reduced cerebral blood flow—that impair brain performance.
Rest & Recovery: What the Science Supports
After a concussion, brief rest (24–48 hours) is beneficial, but extended physical and cognitive inactivity can delay recovery. The AAP recommends a stepwise return-to-learn and return-to-play protocol under professional supervision.
Concussion Reporting Has Increased – But Why?
Reported youth concussion rates have risen over the past decade, with studies indicating increases between 57% and 200%. However, this rise likely reflects better recognition and reporting, not a true increase in incidence.
-
Initiatives like the CDC HEADS UP program have helped raise awareness and improve concussion protocols across school and recreational sports.
Gender Differences in Concussion Risk
Multiple studies show that female athletes are more likely than males to report concussion symptoms and tend to have higher concussion rates in sports such as soccer and basketball.
Potential reasons include:
-
Lower neck strength in female athletes, may lead to greater head acceleration upon impact.
-
Hormonal factors like estrogen may influence brain response to injury, though research is ongoing.
In contrast, boys have higher concussion rates in contact-heavy sports like football, lacrosse, and ice hockey.
Youth Tackle Football: Higher Risk in Older Children
Data suggest that players aged 11–12 experience significantly more concussions than those aged 8–10 in youth football programs. One study found an almost 2.5x increased risk for the older age group.
Common Concussion Symptoms in Youth
The AAP identifies the following as the most frequently reported symptoms among children and teens with concussions:
-
Headache: 86–96%
-
Dizziness: 65–75%
-
Difficulty concentrating: 48–61%
-
Confusion: 40–46%
These symptoms can also mimic pre-existing conditions such as migraine, ADHD, or sleep disorders, making proper clinical evaluation crucial.
SCAT Tools for Sideline Evaluation
The Sport Concussion Assessment Tool (SCAT5) and Child SCAT5 are the most widely used tools for sideline concussion screening. They include:
-
Symptom checklists
-
Memory and concentration tasks
-
Balance tests
-
Neurological assessments
However, SCAT tools are not diagnostic and are most useful when compared to baseline assessments. Also, children under 12 may perform poorly on certain cognitive tasks, so the Child SCAT5 should be used for this group.
Visual-based tools like the King-Devick test are promising but not yet validated for widespread clinical use in children.
Are CT or MRI Scans Needed After a Concussion?
Imaging tests like CT scans or MRIs are not recommended for diagnosing concussions unless a more serious brain injury is suspected (e.g., skull fracture, hemorrhage).
-
CT scans are faster but expose children to radiation.
-
MRI is better for detecting subtle injuries like white matter damage, but is more expensive and less accessible in emergencies.
Imaging should only be used when symptoms suggest a structural brain injury.
Baseline Neurocognitive Testing: Not Foolproof
Computer-based tests like ImPACT or CNS Vital Signs aim to detect subtle cognitive changes post-injury, but concerns remain:
-
Results can vary from year to year, even without injury.
-
Fatigue, ADHD medication, anxiety, or poor sleep can distort results.
-
Athletes may intentionally “sandbag” baseline tests, although trained professionals can often detect this.
Baseline testing should never be the sole determinant of return-to-play decisions.
Multiple Concussions: When Should an Athlete Retire?
There is no established number of concussions that requires retirement. Instead, decisions should be individualized and made in consultation with a specialist in pediatric concussion management, particularly for athletes with:
-
Multiple concussions
-
Prolonged recovery
-
Increasing severity of symptoms
What Actually Works to Prevent Concussions?
Unproven or Ineffective Methods
-
Mouthguards: Do not reduce concussion risk, though they protect teeth and jaws.
-
High-tech helmets and brands: No significant difference between helmet models in preventing concussions.
-
Aftermarket helmet accessories (sensors, pads): No current evidence supports their effectiveness.
-
Soccer headgear: Studies show no reduction in concussion risk and may encourage more aggressive heading behavior.
Evidence-Backed Strategies
-
Education: Teaching symptom recognition and proper response protocols improves outcomes.
-
Neck Strengthening: Stronger neck muscles can help reduce head acceleration during impacts. One study showed that each pound of neck strength may reduce concussion risk by 5%.
-
Rule Changes: Policy changes like banning heading in youth soccer and limiting full-contact practices in football have reduced concussion rates.
Supplements and Biomarkers: Not Ready for Clinical Use
Though researchers are exploring biomarkers (like blood-based proteins) and nutritional supplements (such as omega-3 fatty acids) for concussion diagnosis and recovery, no supplements or biomarkers are currently validated for clinical use in youth populations.
Final Takeaways
-
Concussions in youth sports are neurological injuries, not minor knocks.
-
Rest is important, but prolonged restriction may be harmful.
-
Prevention is best achieved through education, neck strengthening, and rule enforcement—not gear or supplements.
-
Diagnosis and return-to-play decisions must
