Three former NFL players have been diagnosed with having signs of chronic traumatic encephalopathy (CTE), including former Dallas Cowboys great and football Hall of Famer Tony Dorsett, 59. Up until recently, the only way to diagnose CTE was by studying brain tissue after death, but a UCLA research team has pioneered a brain-imaging technique that identifies a build-up of abnormal proteins called tau in the brain.
The other players diagnosed were Hall of Fame offensive lineman Joe DeLamielleure, 62, and former All-Pro defensive lineman Leonard Marshall, 52. One other unidentified player was also tested but his results are not yet known.
The presence of tau in the amygdala and subcortical regions of the brain is believed to be triggered by trauma from repeated blows to the head.

三名前任國家橄欖球隊隊員被診斷出患有慢性創(chuàng)傷性腦病(CTE)的跡象,其中包括達拉斯牛仔隊的殿堂級人物——59歲的Tony Dorsett。
直到最近,診斷CTE的唯一途徑還是研究患者死后的腦組織,但是加州大學洛杉磯分校的研究團隊開創(chuàng)了一種腦成像技術(shù),這種技術(shù)可以識別一種叫做“tau”的異常蛋白質(zhì)在腦中的聚集體。
其他被診斷為CTE的球員還有位列名人堂的進攻前鋒,62歲的Joe DeLamielleure和前職業(yè)防守前鋒52歲的Leonard Marshall。另一位身份不明的球員也接受了測試,但是他的測試結(jié)果尚且不得而知。
研究人員認為tau蛋白在大腦杏仁核和皮質(zhì)下區(qū)域存在的原因是反復打擊頭部所引發(fā)的創(chuàng)傷。

三名美國職業(yè)橄欖球大聯(lián)盟的前隊員被診斷為患有慢性創(chuàng)傷性腦病變(CTE),其中包括現(xiàn)今59歲的前達拉斯牛仔隊的名人堂級球員托尼多賽特。
直到最近,診斷CET的唯一方法還只是研究死后的腦組織,但是加州大學洛杉磯分校的一個研究小組已經(jīng)率先研發(fā)出一種腦造影技術(shù),這項技術(shù)能夠識別出大腦內(nèi)部一種名為tau蛋白的異常。
另外兩名隊員分別是62歲的名人堂進攻線衛(wèi)喬德拉梅列爾和52歲的前全明星防守線衛(wèi)萊納德馬歇爾。還有一名身份不明的球員也接受了檢查,但他的檢查結(jié)果還沒有得出。
大腦的扁桃體和皮下區(qū)域出現(xiàn)的Tau 蛋白已經(jīng)被確定為是由頭部的反復撞擊造成的損傷所致。 |
