CLINICAL MEDICINE

Detailed explanation-1: -The Glasgow Coma Scale (GCS) classifies Traumatic Brain Injuries (TBI) as Mild (14–15); Moderate (9–13) or Severe (3–8). The ATLS modified this classification so that a GCS score of 13 is categorized as mild TBI.

Detailed explanation-2: -Interpretation of the GCS total score is as follows: Minor head injury = 13-15. Moderate head injury = 9-12. Severe head injury (coma) = 8 or less.

Detailed explanation-3: -GCS is the common scale to assess the level of consciousness after injury. According to the GCS, TBI is classified as mild (13–15 GCS), moderate (9–12 GCS), and severe (3–8 GCS). Debate exists over whether GCS 13 should be classified as moderate or mild TBI (Steyerberg et al., 2019).

Detailed explanation-4: -Patients with scores of 3 to 8 are usually considered to be in a coma. Generally, brain injury is classified as: Severe, GCS ≤ 8. Moderate, GCS 9–12.
