Our young African-Caribbean athletes put themselves at risk every time they step on the field, or step in the ring

In the African-Caribbean communities, there is a strong cultural emphasis on sports, especially high-impact sports. Certain sports, such as football or basketball, are particularly popular and create a sense of identity and pride associated with participation.

The presence of successful African-Caribbean athletes who have excelled in high-impact sports serve as role models for aspiring young athletes. When young people see individuals who look like them achieving success in sports, it inspires them to pursue similar paths.

High-impact sports often offer opportunities for scholarships, college recruitment, and potentially professional careers. For our youth, engaging in these sports can be a pathway to higher education, financial stability, and social mobility.

Sports fans out there have their favorite American football players, their favorite boxers, their favorite MMA fighters, but what many of us don’t realize is that these individuals put themselves at risk every time they step on the field, or step in the ring.

An estimated 50 million new TBI cases are reported worldwide each year and this figure has been increasing. The trend prompted scientists to launch CENTER-TBI, a European Union-funded project aimed at improving care for Traumatic Brain Injury patients.

Even light bumps on the head can cause long-term problems, and researchers may now have an idea why: the brain’s wiring can change in the aftermath of mild concussions.

Prior studies suggested that even mild traumatic brain injuries (TBI) that don’t cause any observable structural damage can still trigger symptoms that persist long term. These symptoms range from problems with concentration and fatigue to depression and anxiety.

Research has found that although there are treatments available for moderate to severe TBI, the understanding of mild TBI and its long-lasting symptoms remains poor.

The CENTER-TBI dataset is unique because, in addition to brain scans, it includes behavioral data, clinical outcomes and biomarkers. Co-senior author Emmanuel Stamatakis, whose University of Cambridge lab specializes in developing methods to understand fMRI data, reported “This makes it possible to relate brain function to observed behavior.”

What has been found is that the brain adapts to injury in other areas of the brain by increasing their connections to the thalamus. The thalamus’ position at the center of the brain also makes it vulnerable to injury from impacts, whatever direction they come from, so the increased connectivity could also be a response to direct thalamus injury.

The thalamus is often described as the “relay” of the brain, because many signals pass through the structure before being shuttled elsewhere. The thalamus is involved in not only primary sensory functions, such as seeing and smelling, but also various complex functions that activate multiple brain regions simultaneously, like concentrating.

Next, the researchers plan to look at the effects of repetitive concussions as often seen in sports, to see whether TBI has cumulative effects.

It’s crucial to let our young men/women know that they must prioritize safety by wearing appropriate protective gear, practicing proper technique, and following the rules and guidelines set forth by the respective sports organizations. We need their young minds to guide us into the future.
