Glasgow coma scale

December 9, 2017

A standardized system used to assess the degree of brain impairment and to identify the seriousness of injury in relation to outcome. The system involves three determinants: eye opening, verbal responses and motor response – all of which are evaluated independently according to a numerical value that indicates the level of consciousness and degree of dysfunction. Scores run from a high of 15 to a low of 3. Persons are considered to have experienced a “mild brain” injury when their score is 13 to 15. A score of 9 to 12 is considered to reflect a “moderate” brain injury and a score of 8 or less reflects a “severe” brain injury.
