Glasgow Coma Scale
Comas are rated according to the Glasgow Coma Scale (GCS), which assesses three different functions: eye opening, motor response, and verbal response. Scores can range from 15 to 3. A lower score indicates a person is less responsive. Scores are interpreted as follows:
• 15-13-mild brain injury
• 12-9-moderate brain injury
• 8 or less-a severe brain injury
