Which statement accurately reflects the factors used to classify TBI severity?

• A. Glasgow Coma Scale, duration of Loss of Consciousness, and duration of Post-Traumatic Amnesia
• B. Mechanism of injury and patient age
• C. CT findings alone
• D. Seizure history only

Answer: (A)

Severity classification in traumatic brain injury is based on objective measures of brain function and its immediate impact, not just what imaging shows or what happened first. The key factors are the level of consciousness at presentation (often measured with the Glasgow Coma Scale, which combines eye, verbal, and motor responses into a 3–15 score), how long the person was unconscious, and how long they experienced post-traumatic amnesia. A lower GCS score, longer unconsciousness, and longer PTA all point to a more severe injury and worse prognosis. Using these three together provides a practical and consistent way to separate mild, moderate, and severe TBI. Imaging findings from CT are crucial for acute management—identifying bleeding, swelling, or mass effects—but they don’t define severity on their own because imaging can be normal in serious cases and abnormal findings don’t always predict outcome. Similarly, mechanism of injury and patient age influence risk and recovery but do not by themselves determine how severe the injury is. Seizure history affects treatment considerations but isn’t a primary criterion for severity classification.
