BU CTE study reveals early brain damage in young athletes from head impacts

A new BU CTE study reveals repetitive head impacts cause brain damage in young athletes before CTE onset. Researchers found significant neuron loss, inflammation, and vascular damage in young contact sport athletes, even those without CTE, suggesting early brain injury independent of the disease. The findings could alter perceptions of contact sports and emphasize the need for reduced head impacts at all levels to protect athletes.
