Severe brain injury corresponds to which GCS total score range?

Explanation:
The key idea is how the Glasgow Coma Scale (GCS) translates into levels of brain injury severity. The total GCS ranges from 3 to 15, with lower scores showing deeper impaired consciousness. Severe brain injury is defined by a score of 8 or less, which typically reflects coma or near-coma states. Scores from 9 to 12 indicate moderate impairment, and 13 to 15 indicate mild impairment. The option describing 3 to 15 as a severity category isn’t a specific level of severity—it’s simply the full possible score range. That's why the 8 or less option best identifies severe brain injury.
