In clinical terms, a Glasgow Coma Scale score of 15 is generally considered?

• A. A sign of coma
• B. Severe brain injury
• C. Normal consciousness
• D. Moderate impairment

Answer: (C)

Glasgow Coma Scale measures level of consciousness by scoring eye opening, verbal response, and motor response, with a total range from 3 to 15. A score of 15 means each domain is at its best—eyes open spontaneously, verbal response is fully oriented, and the patient follows commands. That combination corresponds to normal consciousness and no detectable impairment in these functions.

In practice, a very low score indicates coma or severe brain injury (often ≤8 for coma), while mild injuries hover toward higher scores. Keep in mind factors like sedation, intoxication, or intubation can affect the components, especially the verbal score, even if consciousness is otherwise normal.
