(尤指头部受到撞击后导致的)脑震荡:一种轻度创伤性脑损伤,常见表现包括头痛、眩晕、恶心、短暂意识模糊、记忆或注意力受影响等。(也可泛指“震荡、冲击”,但最常用的是医学/运动伤害义。)
/ˈkən.kʌʃ.ən/
He got a concussion after hitting his head.
他撞到头后得了脑震荡。
Although she never lost consciousness, the doctor diagnosed a concussion and told her to rest and avoid screens for a few days.
虽然她没有失去意识,医生仍诊断为脑震荡,并让她休息几天、避免看屏幕。
来自拉丁语 concutere(“猛烈摇动、震动”),由 *com-*(加强/共同)+ quatere(“摇动、击打”)构成。后来经由中古法语进入英语,逐渐固定为医学上“脑震荡”的含义。
