  • 1 out of 10 high school athletes who participate in contact sports will sustain a concussion each season
  • It’s estimated that up to 20% of high school football players will sustain a concussion per season
  • Younger athletes are at high risk for sustaining a concussion and may take longer to recover

Supporting Your Child

What to do if a child sustains a concussion?

A concussion occurs when there is a physical blow to the body or head causing an injury to your brain.

Shortly after a concussion, the athlete may experience cognitive, physical, and emotional symptoms.

  • After a suspected concussion, a physician should always evaluate your child.
  • Depending on the severity of your child’s injury and symptoms, your child’s physician may order neuroimaging procedures (i.e., MRI or CT Scan).
  • It is very important to rest from physical activity while one is recovering from a concussion; however, your child should try to return to school as soon as possible, with a “safety net” of accommodations and modifications in place.

    For example, Dr. Kirk typically recommends that upon returning to school, the child is allowed to take breaks during the school day, postpone exams, and have limited homework demands.
  • Most children experience a full recovery within a matter of days to weeks following an uncomplicated concussion; however, if your child’s post-concussive symptoms persist beyond 2-3 weeks and/or they are struggling in school, they should be referred to a neuropsychologist.
  • Our doctors also recommend a neuropsychological evaluation prior to return to play for athletes who have a history of multiple concussions.
  • Our doctors are available for presentations regarding concussion awareness and safe concussion management.

Concussion evaluation and TEsting in Colorado

Kirk Neurobehavioral Health (Kirk NBH) in Louisville, Colorado, offers specialized care for children, adolescents, and young adults recovering from concussions. Led by Dr. John Kirk—credentialed as an independent concussion expert by the NFL, NHL, and MLS—the clinic provides expert neuropsychological evaluations and return-to-play guidance for athletes, including those affiliated with professional teams like the Denver Broncos, Colorado Avalanche, and Colorado Rapids.

Concussions, often resulting from blows to the head or body, can lead to cognitive, physical, and emotional symptoms. Young athletes are particularly vulnerable, with 1 in 10 high school participants in contact sports sustaining a concussion each season. Symptoms such as confusion, memory issues, headaches, and behavioral changes may arise.

At Kirk NBH, we emphasize prompt medical evaluation following a suspected concussion. While rest from physical activity is crucial, a timely return to school with appropriate accommodations—like extended test times or reduced homework—is recommended. If symptoms persist beyond 2–3 weeks or academic challenges continue, a comprehensive neuropsychological assessment is advised. Additionally, athletes with multiple concussions should undergo evaluation before resuming sports.

With over two decades of experience, Kirk NBH is committed to supporting young individuals through recovery, ensuring safe reintegration into daily activities.
