The article focuses on the Glasgow Coma Scale (GCS), a widely used tool for assessing a patient's level of consciousness, particularly in cases of traumatic brain injury or acute brain impairment. It highlights the importance of GCS in managing patients with reduced consciousness.
The article details several developments designed to improve and expand the usefulness of the GCS, including:
GCS Aid: A structured approach to GCS assessment, providing a framework for standardized examination and ensuring consistent, reliable results.
GCS Pupils score (GCS-P): A simple scoring system used to estimate patient outcome; however, it's not a replacement for the GCS.
Verbal Imputation Score: An additional scoring element contributing to a more comprehensive assessment.
These additions aim to enhance the accuracy and applicability of the GCS in clinical practice.
Assessing a patient's level of consciousness using the GCS provides an indication of potential intracranial complications before further deterioration. The management of patients depends on their condition and potential causes, which are determined through clinical history, assessment, and further investigations.

The GCS Aid is an adjunct to the GCS and provides a structured approach to assessing consciousness. It was devised to provide a framework for standardised examination and to support consistent, reliable GCS assessment

For patients with a traumatic brain injury or other acute brain impairment (such as stroke, infective cerebritis, or toxic encephalopathy), assessment of their clinical condition, and how it may change, is fundamental to their care. For almost 50 years, the Glasgow Coma Scale (GCS) has been used worldwide to assess a patient’s responsiveness, or level of consciousness,1 in acute brain impairment.2 When using the GCS, the response of a patient is documented in three components: eyes, verbal, and motor. Each of these components is assessed simultaneously. Over time, lessons learnt have prompted developments to support and extend the usefulness of the GCS. Awareness of the various GCS tools is useful for all doctors involved in the assessment or management of acutely unwell patients. This article offers an overview of the most recent updates, including the GCS Aid,3 GCS Pupils score (GCS-P),45 and the verbal imputation score.6 We discuss how to apply these tools in clinical practice.
Assessment of a patient’s level of consciousness with the GCS provides an index of the likelihood of intracranial complications before further deterioration occurs. The management of patients with reduced consciousness is influenced by their clinical condition and the potential causes (box 1). Investigation of the possible causes requires review of a patient’s clinical history, a thorough clinical assessment, and investigations such …
