A recent study published in JAMA Network Open reveals that approximately 74.5% of deceased former NFL players suffered from chronic traumatic encephalopathy (CTE), a degenerative brain disease directly tied to repetitive head trauma.

This striking statistic inevitably forces parents of children and young adults playing tackle football to weigh a difficult choice: should youngsters continue participating in a sport with documented long-term neurological dangers?

As both a medical doctor and a parent—as well as a former high school football player from an era when such data was nonexistent—this issue hits particularly close to home.

The findings, however, should not trigger immediate panic. Instead, they serve as a critical data point that families must evaluate alongside existing scientific literature.

The core factor driving severe brain injury is cumulative exposure. The overall risk scales with the number of years played, the level of competition, and the frequency of impacts. The vast majority of children who participate in youth or high school football for a few seasons never approach the cumulative exposure levels seen in a professional NFL career.

Furthermore, while broader population data regarding former high school athletes remains largely reassuring, specific studies continue to highlight measurable brain alterations following just a single season of play.

Breakdown of the JAMA Network Open Study

Historically, much of what researchers understood about CTE derived from brain banks, where families donate a deceased loved one's brain for scientific study.

A natural selection bias exists within these repositories. Families of individuals who displayed neurological symptoms—such as severe memory loss, behavioral challenges, or mood fluctuations—are far more likely to donate, artificially inflating the apparent disease prevalence compared to the general population.

To correct for this distortion, researchers analyzed the death records of 2,362 former NFL players who passed away between 2008 and 2023. Out of that cohort, 396 individuals were brain donors, and 94% of those specific donors exhibited CTE.

The research team estimated that players showing distinct cognitive symptoms were roughly five times more likely to have their brains donated. Once adjusted for this bias, the prevalence rate for the entire group adjusted to 75%, with a 95% confidence interval spanning from 70% to 78%.

Contrasting Head Impact Dangers: Professional versus Youth Sports

Professional athletes accumulate extensive exposure long before reaching the league. A child playing recreationally takes far fewer hits, offering a degree of reassurance. Nevertheless, this comfort is tempered by the reality that children's brains are still developing, and early exposure introduces unique vulnerabilities.

Scientific literature consistently demonstrates a dose-response relationship between football impacts and CTE. An analysis featured in the American Journal of Epidemiology indicated that college and professional players face roughly two and a half times the CTE risk of athletes whose careers ended in high school.

During a single season, an individual player—even at the high school level—might absorb anywhere from 500 to upwards of 2,000 head strikes. A 2026 study in the Journal of Neurotrauma tracked 87 player-seasons showing no clinical evidence of concussions. It found that higher cumulative impact exposure directly correlated with frontal cortex changes visible on MRIs. These physical alterations appeared exclusively within the high-exposure cohort, aligning with brain regions typically affected by CTE.

Additional research highlights that compared to non-contact athletes, football participants experienced diminished brain connectivity at the close of the season. They also demonstrated slower improvements in verbal and visual memory, with 27% scoring lower than expected on verbal memory tests, compared to just 6% of non-contact peers.

Autopsy investigations focusing on young contact-sport athletes have likewise identified early-stage CTE. A 2023 study published in JAMA Neurology analyzed 152 brain donors under the age of 30, uncovering CTE in 63 cases—predominantly mild. Notably, 16 of those individuals had never played football past high school, and two donors who played exclusively youth football had substantial head-impact exposure stemming from other activities.

Conversely, other investigations offer encouraging findings. Research published in Biological Psychiatry observed that former high school athletes from the 1957–1970 cohorts experienced no elevated rates of neurodegenerative disease or cognitive impairment when compared to matched control groups.

A primary limitation across much of this literature is that it does not directly isolate severe head impacts, namely clinical concussions. A concussion represents a distinct head trauma causing temporary disruption in how cellular pathways and brain chemicals communicate.

Proper Protocol for Managing Concussions

While most children and adolescents recover from concussions within a month, healing times can occasionally extend significantly. Continuing to participate in athletic activities immediately following an injury prolongs recovery, while returning to contact sports prematurely drastically increases the danger of severe reinjury.

The American Academy of Pediatrics (AAP) maintains a definitive stance: no young athlete should return to play on the same day they suffer a suspected concussion. Their guiding philosophy remains clear: When in doubt, sit them out.

Furthermore, young athletes must not resume physical contact until all symptoms have completely subsided, they have successfully reintegrated into full academic workloads, and they have cleared a gradual, stepwise return-to-sport progression. Any child experiencing multiple concussions, or dealing with recovery timelines exceeding four weeks, requires evaluation by a specialist experienced in pediatric concussion management.

Parents must remain vigilant for persistent headaches, prolonged symptom durations, and sudden shifts in mood, attention, sleep patterns, or memory. Any of these warning signs demand professional medical assessment. No matter what pressure comes from coaches or teams, a symptomatic child should never receive clearance to play.

Proven Strategies to Enhance Tackle Football Safety

Despite documented hazards, many families choose to let their children play. To mitigate risk, the single most effective structural adjustment is curtailing full-contact drills during practice sessions.

A 2022 meta-analysis featured in Sports Medicine demonstrated that youth leagues implementing coaching education on proper tackling techniques alongside strict limitations on practice contact achieved dramatically lower concussion rates compared to programs utilizing neither measure.

Treating tackling as a fundamental, highly technical skill rather than a display of toughness is essential. The AAP actively advocates for zero-tolerance policies penalizing illegal head-first impacts.

Conversely, protective equipment offers limited defense against concussions. While properly fitted helmets successfully reduce catastrophic injuries like skull fractures and intracranial hemorrhaging—making them mandatory—the AAP notes that no specific helmet model or aftermarket accessory has been proven to prevent concussions entirely. Families should never rely on helmet safety ratings alone.

Some safety advocates push for postponing the introduction of tackle football until later childhood. While the AAP acknowledges that delaying tackling eliminates injuries at younger ages, they caution that older, faster adolescents hitting with greater force could face elevated injury risks unless they master proper technique beforehand.

Parents should consider asking program organizers the following vital questions before enrolling a child:

  • Is a certified athletic trainer present at all practices and games, as recommended by the AAP?
  • Does the organization maintain a strict, written concussion protocol requiring medical clearance before returning to play?
  • What specific limits govern the amount of full-contact tackling permitted during weekly practices?
  • Are coaching staffs formally trained in safe tackling mechanics, and are illegal helmet impacts strictly penalized?
  • Are all athletic injuries systematically tracked, recorded, and reported?

The answers to these inquiries will provide profound insight into an organization's safety culture and overall commitment to player well-being.

Ultimately, the finding that three out of four former NFL players show evidence of CTE underscores the severe long-term risks associated with a sustained professional career. While existing scientific literature does not draw the exact same definitive line for high school sports, parents must arm themselves with current research before making an informed decision.

Families should carefully balance the physical, social, and emotional benefits of exercise, teamwork, and camaraderie against the inherent physical risks, favoring leagues that prioritize athlete protection. Personally, my own high school football background provided immense foundational value, instilling resilience, grit, and discipline that directly benefited my medical career.

For those who choose to support their child's participation in tackle football, the most prudent course of action involves asking the right safety questions, monitoring closely for symptoms, and acting decisively. If a program fails to meet rigorous safety standards, alternative options like flag football deliver many of the same athletic rewards with significantly reduced head impact exposure.
