On the Glasgow Coma Scale, how many points are awarded for spontaneous eye opening?

In the Glasgow Coma Scale, spontaneous eye opening is the highest level of eye response and is awarded a total of four points. This scale is used to assess a person's level of consciousness based on three aspects: eye opening, verbal response, and motor response. The eye opening responses range from no eye opening at all, which scores one point, to eye opening in response to speech, which scores three points. If a person opens their eyes without any stimulus—indicating they're awake and aware without prompting—they receive the maximum score of four points. This scoring reflects a better neurological function and higher level of alertness compared to other responses, which is critical for assessing the severity of brain injuries or consciousness levels in patients.
