Which GCS score defines severe brain injury?

Which GCS score defines severe brain injury?

• A. 3 or less
• B. 8 or less
• C. 9 to 12
• D. 13 or higher

Answer: (B)

Glasgow Coma Scale is used to gauge level of consciousness by adding three components: eye opening, verbal response, and motor response, giving a total score from 3 to 15. A score of eight or less defines severe brain injury because it reflects substantial impairment across the board—little to no eye opening, severely reduced or absent verbal response, and poor motor response. This level typically means the patient cannot protect their airway and has a high risk of deterioration, prompting urgent airway management and aggressive treatment. Scores from nine to twelve indicate moderate injury, while thirteen to fifteen indicate mild injury with better responsiveness and prognosis. The key takeaway is that eight or fewer marks severe impairment and drives urgent, life-saving decisions.
