Glasgow Coma Scale

The Glasgow Coma Scale or GCS is a neurological scale that aims to give a reliable, objective way of recording the conscious state of a person for initial as well as subsequent assessment.

The Glasgow Coma Scale (GCS) is the most common scoring system used to describe the level of consciousness in a person following a traumatic brain injury.

Based on a 15 point scale for estimating and categorizing the outcomes of brain injury on the basis of overall social capability or dependence on others.


The GCS measures the following functions:

Eye Opening (E)

  • 4 = spontaneous
  • 3 = to voice
  • 2 = to pain
  • 1 = none

Verbal Response (V)

  • 5 = normal conversation
  • 4 = disoriented conversation
  • 3 = words, but not coherent
  • 2 = no words, only sounds
  • 1 = none

Motor Response (M)

  • 6 = normal
  • 5 = localized to pain
  • 4 = withdraws to pain
  • 3 = decorticate posture (an abnormal posture that can include rigidity, clenched fists, legs held straight out, and arms bent inward toward the body with the wrists and fingers bend and held on the chest)
  • 2 = decerebrate (an abnormal posture that can include rigidity, arms and legs held straight out, toes pointed downward, head and neck arched backwards)
  • 1 = none

Clinicians use this scale to rate the best eye opening response, the best verbal response, and the best motor response an individual makes. The final GCS score or grade is the sum of these numbers.


Using the Glasgow Coma Scale

Every brain injury is different, but generally, brain injury is classified as:

  • GCS 3 – 8: Severe (You cannot score lower than a 3)
  • GCS 9 – 12: Moderate
  • GCS 13 – 15: Mild
    • Mild brain injuries can result in temporary or permanent neurological symptoms and a neuro-imaging tests such as CT scan or MRI may or may not show evidence of any damage.

      Moderate and severe brain injuries often result in long-term impairments in cognition (thinking skills), physical skills, and/or emotional/behavioral functioning.
