What does GCS mean?

Glasgow Coma Scale (GCS) is a neurological scale used to assess a patient's level of consciousness after a head injury or other neurological disorders. It was first introduced by Graham Teasdale and Bryan J. Jennett in 1974 at the University of Glasgow located in Scotland, United Kingdom.

GCS is designed to assess a person's level of consciousness through three key areas:
Eye response: This evaluates how a person opens their eyes in response to stimuli.
Verbal response: This assesses the patient's ability to communicate and respond verbally.
Motor response: This evaluates the patient's ability to move their body in response to commands or stimuli.

Each of these tests is scored independently, and then the scores are summed to give a total score. The lowest possible GCS score is 3 (indicating deep coma), while the highest is 15 (indicating full alertness).
