Glasgow Four

The Glasgow Four refers to four phenomena observed in the brain during certain neurological conditions: the Glasgow Coma Scale (GCS), which assesses consciousness level; pupillary light reflexes, indicating brainstem function; eye movements, reflecting brain activity; and motor responses, showing motor pathway integrity. These components help doctors evaluate brain function, especially in patients with brain injuries or coma. Each element provides essential information about different parts of the brain, aiding diagnosis and prognosis. They're part of comprehensive neurological assessments, offering a structured way to understand the brain's responsiveness and health.
