澳大利亚前国家橄榄球队球员纳森·查尔斯于9月13日被诊断为运动神经元病（MND）1。查尔斯曾在2014年代表澳大利亚参加过4场测试赛1。他形容这一诊断"极其具有挑战性和压倒性的，有时相当残忍"1。
这一确诊病例引发了对接触性运动与运动神经元病潜在关联的关注。研究数据表明，精英运动员患MND的风险增加了4至15倍1。其中，2022年对前苏格兰国际橄榄球联盟球员的研究发现，他们被诊断为MND的可能性高出15倍1；前美式橄榄球联盟球员死于MND的可能性增加4.5倍1；足球运动中头球导致的MND风险增加近两倍1。
澳大利亚目前约有2,800人患有运动神经元病1。大多数患者在两到五年内面临瘫痪和死亡的风险，约10%的患者可能存活更长时间1。家族性MND约占所有病例的10%左右1。澳大利亚目前缺乏针对橄榄球联盟和澳式足球运动员的MND相关专项研究1。
Nathan Charles, a former Australian rugby international, has been diagnosed with motor neurone disease (MND) on September 13, adding to a growing list of contact sport athletes affected by the condition 1. Charles played four test matches for Australia's national rugby team in 2014 and has described his diagnosis as "extremely challenging and overwhelming, sometimes quite cruel" 1.
The case highlights emerging concerns about a potential connection between contact sports and MND risk. Research indicates that elite athletes face a dramatically elevated risk, with former Scottish international rugby union players showing a 15-fold higher likelihood of MND diagnosis, while former NFL players have a 4.5-fold increased risk of death from the disease 1. Football heading has been associated with a nearly doubled MND risk 1. However, Australia currently lacks dedicated research on MND incidence among rugby league and Australian football players 1.
MND remains a serious neurological condition affecting approximately 2,800 Australians, with most patients facing paralysis and death within two to five years, though about 10 percent may survive longer 1. Familial cases account for roughly 10 percent of all MND cases 1. The precise mechanisms linking contact sports to MND require further investigation to establish definitive causation.
