Which score reflects the least responsiveness in a GCS assessment?

In a Glasgow Coma Scale (GCS) assessment, the scoring system is designed to evaluate a person's level of consciousness and responsiveness. The GCS consists of three components: eye-opening response, verbal response, and motor response, each contributing to the overall score, which ranges from 3 to 15.

A score of 1 indicates the least responsiveness possible within this scale. It represents a complete lack of response in any of the assessed areas – meaning the individual does not open their eyes, does not respond verbally, and does not move in response to stimuli. This score signifies that the patient is unresponsive and requires immediate medical attention.

Scores greater than 1, such as 3, 5, or 6, indicate varying levels of responsiveness. For example, a score of 3 demonstrates some form of response, even if minimal. Higher scores reflect an increasing level of consciousness and responsiveness. Therefore, a score of 1 distinctly stands out as the lowest possible score in the GCS, marking the least level of responsiveness.
