Recent research by scientists from Boston University, the University of Glasgow, and the University of Sydney suggests a direct link between the duration of a rugby union player's career and an increased risk of developing chronic traumatic encephalopathy (CTE), a brain condition prevalent among contact sports athletes. This study evaluated post-mortem brain exams from 31 former amateur and pro rugby union players, revealing a 14% rise in CTE risk for each added year of play as reported by the Boston Herald.
CTE is often linked to American Football players—they are subjected regularly to repeated head impacts and concussion injuries. It can only be officially diagnosed post-mortem. The study, which analyzed brain donations from the U.S., UK, and Australia, found 68% of the brains examined had CTE, affecting both low-level and elite-level players, according to the Independent.
Professor Willie Stewart from the University of Glasgow, a leading author for the study, emphasized the crucial nature of limiting repeated head impacts in both games and training to reduce CTE risk, described as a preventable disease associated with contact sports. The risk factors for developing CTE, according to the research, are directly related to the player's career length rather than the playing position or participation level, states the Boston Herald.
Ann McKee, the BU CTE Center and UNITE brain bank director, assured Stewart's views, emphasizing the urgent need to lessen both the frequency and the magnitude of head impacts in rugby and other contact sports, to safeguard players from CTE, as reported by the Independent.
It is well established that rugby union poses a high risk for concussion, with professional levels having higher injury rates. World Rugby is currently exploring means for enhancing concussion management and minimizing head impact exposure. Strategies being considered include globally trialing a reduction in tackle height to below the sternum, known as a "belly tackle." Furthermore, a "recognize and remove" tactic is being promoted, alongside comprehensive return-to-play protocols designed to address concussions in amateur and elite tiers of the sport, according to the Independent.
Legal action has been taken against World Rugby, the Rugby Football Union, and the Welsh Rugby Union by a group of former professional and amateur players diagnosed with early-onset dementia. They claim that these governing bodies failed in taking reasonable precautions to prevent permanent injury caused by repeated concussive and sub-concussive impacts, as published in the Independent.
Following the conclusion of the University of Glasgow study, a representative from World Rugby reasserted their commitment for aligning with the latest scientific evidence and working alongside top brain health experts to decrease the occurrence of head impacts in the sport. This commitment aligns with the counsel provided by the Independent Concussion Working Group and Professor Ann McKee from Boston University, according to the Independent.
