Glasgow Coma Scale score calculation

The Glasgow Coma Scale (GCS) assesses a person's level of consciousness after a brain injury by examining three areas: eye opening, verbal response, and motor response. Each area has specific scoring options, with higher scores indicating better function. Eye opening is scored from 1 (none) to 4 (spontaneous), verbal response from 1 (none) to 5 (oriented), and motor response from 1 (none) to 6 (obeys commands). The total GCS score is the sum of these three numbers, ranging from 3 (deep coma or death) to 15 (fully alert), helping healthcare providers gauge severity and monitor progress.
