Every brain injury is different, but generally, brain injury is classified as: Severe: GCS 3-8. Intubation and severe facial swelling may preclude the ability to score eye and verbal components. Patients with scores of 3-8 are usually considered to be in a coma. The most widespread revision has been the Simplified Motor and Verbal Scales which shorten the respective sections of the GCS without loss of accuracy. Patients with scores of 3 to 8 are considered to have a severe brain injury. Note that a motor response in any limb is acceptable.

By regularly assessing a patient’s GCS, a downward trend in consciousness level can be recognised early, allowing time for appropriate interventions to be performed. The GCS can be used to monitor the child’s level of consciousness during both the pre-hospital and hospital care. It is commonly used in the context of head trauma, but it is also useful in a wide variety of other non-trauma related settings.

There are four grades starting with the most severe: NT (Not testable). The scale measures three categories: Eye opening (E) Motor response (M) Verbal response (V) The GCS score is the sum of the score in each of the three categories, with a maximum score of 15 (normal) and a minimum score of 3 (deep unconsciousness), as follows: A normal GCS score is equal to 15, which indicates a person is fully conscious. The Glasgow Coma Scale is reported as the combined score (which ranges from 3 to 15) and the score of each test (E for eye, V for Verbal, and M for Motor). This allows for improvement or deterioration in a patient's condition to be quickly and clearly communicated. The GCS helps to define the severity of traumatic brain injury. For these circumstances, the score is frequently noted with a modifier, i.e. Christensen, Buck. Hence, the score is expressed in the form "GCS 9 = E2 V4 M3 at 07:35". Moderate: GCS 9-12. The Glasgow Coma Scale. Individual elements, as well as the sum of the score, are important. A patient's Glasgow Coma Score (GCS) should be documented on a coma scale chart. [10] Although the inter-rater reliability of these newer scores has been slightly higher than that of the GCS, they have not gained consensus as replacements.
