【腦震盪】如何定義？

答案：

Frequently defined as a head injury with a temporary loss of brain function, concussion can cause a variety of physical, cognitive, and emotional symptoms. Traditionally, concussion refers to an immediate and transient loss of consciousness (< 30min) accompanied by a brief period of amnesia (< 24hr) after a blow to the head.
