A Glasgow Coma Scale score of 9-12 indicates which level of head injury?

A Glasgow Coma Scale (GCS) score of 9-12 is indicative of a moderate head injury. This scoring system assesses a patient's level of consciousness based on their eye, verbal, and motor responses to stimuli, with scores ranging from 3 (deep coma or death) to 15 (fully alert).

A score in the range of 9-12 reflects varying degrees of compromised consciousness, showing that the individual has some responsive behaviors but not as robust as a mild injury, which typically corresponds to a GCS of 13-15. This scoring provides critical information for assessing injury severity and guiding further medical intervention. It is essential to recognize that while such patients may be coherent to some degree, their capacity for meaningful interaction and awareness is significantly impacted, separating this condition from both mild and severe head injuries, as well as from coma states where the score would be lower than 9.
