CTE is a brain disease caused by repeated impacts that can lead to bad things.

CTE（慢性创伤脑部病变）是一种由反复撞击所致的脑疾病，这种疾病会导致很多问题。

When doctors did autopsies on former professional football players they saw brains that looked wasted away, from years of repeated impacts that weren't technically concussions.

当医生给前职业足球运动员进行尸检时，医生们会看到很多很虚弱的大脑，由常年反复撞击所致的，虽然这并不是严格意义上的脑震荡。

The organisation is also conducting its own research into head impacts, reviewing existing laws and, it maintains, devising its policy assuming that there is a link between repeated head impacts and CTE.

该组织还在对头部撞击进行自己的研究，审查现行法律， 并坚持认为，假设重复的头部撞击与 CTE 之间存在联系， 从而制定其政策。
