近期發表於《英國醫學期刊》(The BMJ) 的一項研究，對前 NFL 球員所面臨的健康風險有了新的見解。
A recent study published in The BMJ has shed new light on the health risks facing former NFL players.
研究人員檢視了 2016 年至 2021 年間過世的運動員大腦，發現至少有 24.5%的運動員患有慢性創傷性腦病變 (CTE)。
By examining the brains of athletes who passed away between 2016 and 2021, researchers discovered that at least 24.5%—roughly one in four—suffered from Chronic Traumatic Encephalopathy (CTE).
主導作者丹尼爾·達內什瓦爾 (Daniel Daneshvar) 博士將此數據描述為一個保守估計，並指出實際的盛行率可能還要高得多。

由於慢性創傷性腦病變 (CTE) 只能在死後進行確診，這項研究有助於縮小小型腦庫研究與更廣大過世球員群體之間的差距。
Daniel Daneshvar describes this figure as a conservative estimate, noting that the true prevalence could potentially be much higher.
研究結果也揭示了慢性創傷性腦病變 (CTE) 與認知能力下降之間存在明顯的關聯；在患有此病症的人群中，有 61.3% 出現了失智症狀，而在最嚴重的病例中，此比例更超過 90%。
Because CTE can only be definitively diagnosed after death, this study helps bridge the gap between small-sample brain bank research and the broader population of deceased players.
專家將這種職業傷害比作接觸石綿 (Asbestos) 等重大健康風險，因為慢性創傷性腦病變 (CTE) 在一般大眾中的盛行率不到 1%。
The findings also reveal a stark correlation between CTE and cognitive decline; among those with the condition, 61.3% showed symptoms of dementia, with that number rising to over 90% in the most severe cases.
雖然這項研究無法追蹤在世球員的健康狀況，但它已引發了對於加強球員安全與進一步研究該種會改變人生病症的潛在治療方法的急迫呼籲。
Experts compare this occupational hazard to significant health risks like asbestos exposure, as the prevalence of CTE in the general public is less than 1%.
