Introduction

Glasgow Coma Scale (GCS) is the most commonly recognised scoring system used to measure a person’s level of consciousness following a brain injury, it was designed in 1974 by professors of neurosurgery at the University of Glasgow.​

My Recorded GCS Values

The following GCS values were obtained from a neuropsychologist’s report, which contained a consolidation of all my hospital records.

​Anecdote: After my mother suffered heart attack symptoms in 2018, I accompanied her on the ambulance journey to hospital. I enquired of GCS 3 during conversation with the paramedics, they casually said something along the lines of “it basically means you’re dead.”


GCS Scoring System

GCS uses a triple criteria scoring system: best eye opening (maximum 4 points), best verbal response (maximum 5 points), and best motor response (maximum 6 points). These scores are added together to provide a total score between 3 (most severe) and 15 (normal).

Eye Response

Verbal Response
