New Study Finds NFL CTE Risk at 25 Percent

Live Poll

Do you trust current youth sports concussion protocols to effectively protect student athletes from long-term injury?

A study published in the British Medical Journal reveals that at least one quarter of NFL players develop neurodegenerative diseases like CTE. The findings have prompted experts to review whether current youth sports concussion protocols are sufficient to mitigate long-term brain health risks.

Why it matters

Identifying and preventing head impacts during youth sports may reduce the risk of developing neurodegenerative conditions later in life. Public health officials are now weighing these outcomes against existing safety standards for student athletes.

A study published in the British Medical Journal projects that 25% of NFL players will develop a neurodegenerative disease. This data is part of a broader field that includes an estimated 2 million youth concussions occurring annually in the U.S.

The players

British Medical Journal

This is an international peer-reviewed medical trade journal that publishes research findings on global health and clinical practice.

The details

The British Medical Journal study analyzed brains donated by NFL players after their deaths to determine the prevalence of neurodegenerative disease. Current protocols in California require that students suspected of a concussion be removed from play until cleared by a licensed health care provider.

The study on NFL players was published in 2026.

Season Trajectory

The findings force a re-evaluation of California's seven-day return-to-play protocol, which currently governs how schools manage head injuries. This research shifts the narrative from immediate game-day safety to the long-term cumulative effects of contact sports on brain health.

California school coaches must ensure all student athletes follow the mandatory seven-day return-to-play protocol after any confirmed concussion. Because there is currently no MRI or blood test to diagnose a concussion, staff must rely on symptom observation to remove students from play.

The takeaway

Understanding the long-term risks associated with head impacts is essential for parents and coaches in contact sports. Implementing rigorous, science-backed safety protocols remains the primary method for protecting the brain health of youth athletes.
