What is the severity of a head injury with a GCS between 13-15?

• A. Moderate
• B. Mild
• C. Severe
• D. Critical

Answer: (B)

Interpreting Glasgow Coma Scale scores to gauge head injury severity. The Glasgow Coma Scale evaluates eye opening, verbal response, and motor response, with a total from 3 to 15. A score in the upper end, 13 to 15, reflects near-normal mental status and consciousness. This is categorized as mild traumatic brain injury because the patient is typically awake, oriented, and able to follow commands, with only minimal impairment. It may include brief loss of consciousness or transient confusion, but overall brain function is largely preserved. Moderate injury (roughly 9 to 12) shows more noticeable confusion and reduced responsiveness, while severe injury (8 or below) indicates substantial impairment, often coma. So, a Glasgow Coma Scale between 13 and 15 corresponds to mild head injury, usually with a better prognosis, though monitoring is still important since symptoms can evolve.
