Which GCS range defines moderate TBI?

• A. 9-12
• B. 13-15
• C. 3-8
• D. 6-10

Answer: (A)

Understanding how the Glasgow Coma Scale defines injury severity is the key. The GCS sums eye opening, verbal response, and motor response to yield a score from 3 to 15. Moderate traumatic brain injury is the mid-range, typically scoring 9 to 12. This reflects a noticeable but not deepest level of consciousness impairment—patients are not fully alert or oriented, yet they are not in a coma. It sits between mild injuries (13 to 15) and severe injuries (3 to 8). A range like 6 to 10 is less precise for defining moderate because it includes some severe scores (6–8) and excludes some moderate scores (11–12), muddying the boundary.
