Which score on the Glasgow Coma Scale is the highest indicating normal function?

The score of 15 on the Glasgow Coma Scale (GCS) indicates normal function and is the highest possible score. This scale is used to assess a person's level of consciousness following a brain injury. The GCS evaluates three aspects of responsiveness: eye opening, verbal response, and motor response, assigning points based on the severity of impairment.

A score of 15 signifies that a patient is fully alert and oriented, capable of responding appropriately to stimuli. In contrast, lower scores reflect varying degrees of impaired consciousness or coma, where lower values indicate greater degrees of impairment in awareness, response, and functioning. Therefore, a score of 15 is crucial in determining optimal neurological function and recovery potential.
