What does the Glasgow Coma Scale (GCS) assess?

The Glasgow Coma Scale (GCS) is a neurological scale that is specifically designed to assess a patient's level of consciousness after a traumatic brain injury or any acute event that could affect cognitive functioning. It evaluates three key aspects: eye opening, verbal response, and motor response, each of which is scored to give an overall score ranging from 3 to 15. A lower score indicates a more severe impairment in consciousness, while a higher score suggests a better neurological status. The primary purpose of the GCS is to provide a reliable and objective way to monitor changes in a patient's consciousness level, enabling healthcare providers to make informed decisions about further evaluation and interventions.
