“Heading” the ball may pose a risk to amateur soccer players’ brain health, according to a new study published in the journal Neurology. Researchers found that players who frequently use their heads to pass or deflect a soccer ball are more likely to experience changes within the cerebral cortex, the brain’s wrinkly outer layer.
The study, conducted by a team from Columbia University, highlights that athletes with more of these brain changes performed worse on cognitive tests. “People who experienced more impacts from headers had more disruptions within a specific layer in the folds of the brain, and these disruptions were also linked to poorer performance on thinking and memory tests,” stated Dr. Michael Lipton, the senior researcher and a professor of radiology, in a news release.
Study Details and Findings
The research adds to growing concerns about the effects of sports-related head impacts and concussions on players’ brain health. Researchers performed brain scans on 352 amateur soccer players from the greater New York City area, alongside 77 athletes from non-collision sports. The average age of the soccer players was 26 years.
Participants were categorized into four groups based on their frequency of heading the ball. Those in the highest group averaged 3,152 headers annually, compared to just 105 in the lowest group. The scans revealed more significant changes in the white matter within the brain’s folds, known as the “depths of sulci,” among players who headed the ball most frequently.
“Our findings suggest that this layer of white matter in the folds of the brain is vulnerable to repeated trauma from heading and may be an important place to detect brain injury,” Lipton noted.
Impact on Cognitive Performance
As the frequency of headers increased, the white matter in the brain’s orbitofrontal region, located just above the eye sockets, showed more disruption. This disruption was linked to poorer performance on learning and memory tests among the soccer players.
“More research is needed to further explore this relationship and develop approaches that could lead to early detection of sports-related head trauma,” added Lipton, emphasizing the need for continued investigation.
Broader Context and Implications
This study is part of a broader dialogue on the long-term impacts of head injuries in sports. The findings align with previous research that has raised alarms about the potential for chronic traumatic encephalopathy (CTE) and other neurodegenerative conditions resulting from repeated head impacts.
Historically, sports organizations have grappled with the balance between maintaining the integrity of the game and ensuring player safety. In recent years, there have been calls for stricter regulations and protective measures, particularly in youth sports, to mitigate the risks associated with head impacts.
Next Steps and Recommendations
As the conversation around sports-related brain injuries continues, experts advocate for increased awareness and preventive strategies. The study’s authors suggest that understanding the specific brain regions affected by heading could lead to better diagnostic tools and interventions.
Meanwhile, the American Academy of Orthopedic Surgeons and other health organizations continue to provide resources and guidelines on managing sports concussions. As research evolves, these recommendations may adapt to incorporate new findings, ultimately aiming to protect athletes at all levels.
