About the Glasgow Coma Scale (GCS)
The Glasgow Coma Scale (GCS) is a standardised neurological assessment tool measuring level of consciousness. Scores range from 3 (deeply unconscious) to 15 (fully alert).
GCS ≤8 is traditionally associated with severe brain injury and loss of airway reflexes. Always interpret in clinical context.
