The Glasgow Coma Scale (GCS) was devised by doctors to assess head trauma and, importantly, to help keep track of patients' progress over a period of time. The scale is comprised of three tests: eye, verbal and motor responses. The lowest possible GCS is 3 (deep coma) whilst the highest is 15 (fully awake person).
