Introduction

Glasgow Coma Scale (GCS) is the most commonly employed 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 /flippantly said something along the lines of “it basically means you’re dead.”


GCS Scoring System

GCS uses a triple criteria scoring system, whereby the scores for each of the following criteria are added together to provide a single value between 3 (most severe) and 15 (normal).

  • Eyes: minimum 1 point (no response), maximum 4 points (normal response)
  • Verbal: minimum 1 point (no response), maximum 5 points (normal response)
  • Motor: minimum 1 point (no response), maximum 6 points (normal response)
