What is the Glasgow Coma Scale score range for minor TBI?

The Glasgow Coma Scale (GCS) is utilized to assess the level of consciousness in individuals, particularly after a head injury. The scale ranges from 3 to 15, with higher scores indicating a better level of consciousness and functioning.

A score of 13 to 15 on the GCS signifies that the patient has a mild traumatic brain injury (TBI). This range indicates that the individual is fully conscious or only mildly impaired, showing clear responsiveness and ability to follow commands. In clinical practice, mild TBI may occur after a concussion or a minor blow to the head, where the patient retains orientation and cognitive abilities to a significant extent.

On the other hand, scores lower than 13 indicate increasing severity of brain injury, with scores of 9-12 suggesting moderate TBI, and those below 8 generally correspond to severe TBI. Therefore, the correct range for minor TBI is distinctly categorized by the GCS score of 13 to 15.
