About

The Glasgow Coma Scale (GCS) is a neurological scale used to assess the level of consciousness in patients with acute brain injury. It evaluates three components: eye opening, verbal response, and motor response. The GCS is widely used in emergency medicine and critical care for initial assessment, ongoing monitoring, and prognostication.

GCS = Eye Opening (E) + Verbal Response (V) + Motor Response (M)
Range: 3 (worst) to 15 (best)
