New Zealand Confirms First Case of CTE in Former Rugby Player

New Zealand has reported its first confirmed case of Chronic Traumatic Encephalopathy (CTE), a degenerative brain disease linked to repeated head trauma, in a former rugby league player. The 79-year-old man, who died in 2021, had a long history of playing rugby and boxing, representing New Zealand in rugby league during the 1960s and early 1970s. Throughout his career, he sustained multiple minor head knocks, including one that resulted in hospitalization.

Why this matters: This case highlights the urgent need for sporting organizations to prioritize player safety and implement effective concussion protocols to prevent long-term brain damage. As more cases of CTE emerge, it raises critical questions about the future of contact sports and the responsibility of governing bodies to protect athletes' health and well-being.

The former player, whose identity has not been disclosed, experienced a range of neurological and cognitive symptoms later in life. At age 64, he was diagnosed with Parkinson's disease, and by age 70, he exhibited cognitive difficulties, apathy, and low mood. As his condition progressed, he developed dementia, requiring hospital-level care in his final years. Following his death, his brain was donated to the Neurological Foundation Human Brain Bank for analysis.

Neuropathological examination revealed the hallmark signs of CTE, including tau protein deposits in the depths of the brain's sulci. The final diagnosis also included Lewy body disease, consistent with his Parkinson's diagnosis, plus low-level Alzheimer's disease and cerebral amyloid angiopathy. Professor Maurice Curtis, co-director of the brain bank, emphasized the significance of this case, stating,"It's significant because up until this case has come out, there have been a lot of diagnosed cases from other sporting codes, but relatively few from rugby league and rugby union, particularly in a New Zealand context."

The confirmation of CTE in a former New Zealand rugby player highlights the importance of further research into the long-term consequences of repetitive head impacts in sports. While the exact prevalence of CTE among athletes remains unknown, studies have found rates ranging from 9% to 31.8% in contact sport participants. Professor Curtis cautioned that this case is likely"just thetip of the iceberg"and that more cases of CTE are expected to emerge as awareness grows and more athletes donate their brains for research.

The findings from this case contribute to the growing body of evidence linking repetitive head trauma to long-term neurological consequences. As more cases of CTE are identified, it raises important questions about the safety of contact sports and the need for improved concussion protocols and player welfare measures. In response to growing concerns, New Zealand's community rugby league rules were strengthened in 2023 to require medical clearance after a 21-day stand-down period for concussed players. However, some argue that more needs to be done to protect athletes at all levels of the game.

The challenge now lies in finding ways to maintain the spirit and physicality of rugby while minimizing the long-term risks to players' health and well-being. As former player Ken Laban put it,"At the end of the day, we can't sugar coat the reality of what the sport is. If your opponent's got the ball, your job is to stop it, whatever way you can. "The confirmation of CTE in a former New Zealand rugby league player serves as a stark warning of the potential consequences of repetitive head impacts in sports." It is essential that sporting organizations, players, and the wider community work together to prioritize player safety and support ongoing efforts to better understand and prevent CTE.
