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. Basically, it is used to help gauge the severity of an acute brain injury. The test is simple, reliable, and correlates well with outcome following severe brain injury.

Using the Glasgow Coma Scale

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

Severe: GCS 3-8 (You cannot score lower than a 3.)
Moderate: GCS 9-12
Mild: GCS 13-15

„Victima este într-o stare destul de gravă, critică am putea spune, cu un scor Glasgow 4. Ca să păstrăm proporţiile, noi avem scor Glasgow 15, unul care intră în moarte cerebrală are de la 3 în jos şi el are 4.
