Glasgow Coma Scale
Standardized scoring system to assess level of consciousness in neurologically impaired patients.
Full Definition
The Glasgow Coma Scale (GCS) is a standardized neurological assessment tool used to evaluate and monitor the level of consciousness in patients with brain injury or altered mental status. The scale assesses three components: eye opening (1-4 points), verbal response (1-5 points), and motor response (1-6 points), with scores ranging from 3 (worst) to 15 (best). Developed in Glasgow, Scotland, the GCS provides objective measurement for clinical communication and helps guide treatment decisions. Scores of 13-15 indicate mild impairment, 9-12 moderate impairment, and 3-8 severe impairment.
Usage
Usage note: Commonly abbreviated as GCS; always specify the individual component scores.
