How is the Glasgow Coma Scale Scored?

The GCS assigns a score in each of the three criteria, which are then summed to give an overall score ranging from 3 to 15. The scoring is as follows:

- Eye-opening response:
- Spontaneous (4 points)
- To speech (3 points)
- To pain (2 points)
- No response (1 point)

- Verbal response:
- Oriented (5 points)
- Confused (4 points)
- Inappropriate words (3 points)
- Incomprehensible sounds (2 points)
- No response (1 point)

- Motor response:
- Obeys commands (6 points)
- Localizes pain (5 points)
- Withdrawal from pain (4 points)
- Abnormal flexion (3 points)
- Abnormal extension (2 points)
- No response (1 point)

The total GCS score helps classify the severity of brain injury: mild (13-15), moderate (9-12), or severe (3-8).
