The highest occurrence of deaths occurred between the ages of 16-35 years (44.3%), and the most common causes were traffic accidents (53.2%). The mortality rates were 78.5% in GCS 3-8, 13.9% in GCS 9-12, and 7.6% in GCS 13-15. Conclusion: Traumatic brain injury is a significant cause of mortality, and the severity of brain injury is directly related to the level of consciousness (GCS).
