Making GCS as easy as 1, 2, 3, 4, 5, 6.

The Glasgow Coma Scale (GCS) is an easy to use tool for assessing neurological function and brain injury in comatose patients particularly in acute stages of traumatic injury or illness. Due to the simplicity of the scale, however, proper training is often overlooked limiting its usefulness. This manuscript describes the basic components of the GCS and the proper scoring method to elicit accurate evaluations.
