Which of the following GCS scale scores is indicative of a moderate brain injury?

A score of 9-12 on the Glasgow Coma Scale (GCS) is considered indicative of a moderate brain injury. The GCS is a vital tool used to assess a person's level of consciousness following a brain injury, combining different aspects of responsiveness: eye opening, verbal response, and motor response.

A score in the 9-12 range reflects a patient who shows some response and interaction with their environment but is not fully alert or oriented. This level of responsiveness suggests that the patient may need medical attention and rehabilitation, but they still retain a level of cognitive function and a possibility for recovery.

In contrast, scores of 3-8 are indicative of a severe brain injury, where the individual may be in a coma. A score of 13-15 represents mild brain injury, indicating a relatively higher level of consciousness and function. Scores of 1-2 suggest profound impairment and lack of meaningful response. Thus, the range of 9-12 clearly correlates with moderate brain injury and the potential for varying degrees of recovery.
