Mild TBI

Glasgow Coma Scale

The Glasgow Coma Scale is used as a preliminary evaluation tool to gauge the severity of a TBI. It measures post-trauma eye opening abilities, verbal responses and motor responses, assigning each area a score. The scores from each section are then added together for a total score. The lower the score — the more severe the initial traumatic brain injury.
