Describe the main parameters of GCS?

The Glasgow Coma Scale (GCS) assesses a patient's level of consciousness based on three main parameters: eye opening, verbal response, and motor response. Each parameter is scored on a scale that ranges from 1 to 4 for eye opening, 1 to 5 for verbal response, and 1 to 6 for motor response. The total GCS score ranges from 3 to 15, with lower scores indicating more severe impairment of consciousness. This scale is widely used in clinical settings to evaluate and monitor patients with brain injuries or altered mental states.
