Which factors are used to classify the severity of TBI?

• A. Glasgow Coma Scale score, duration of Loss of Consciousness, and duration of Post-Traumatic Amnesia
• B. Age, Mechanism of Injury, and CT findings
• C. Seizure history
• D. Imaging findings alone

Answer: (B)

Severity is best understood as the overall impact and prognosis of the brain injury, which is often gauged by age, mechanism of injury, and CT findings. Age matters because older patients generally have less brain reserve and more comorbidities, leading to slower or poorer recovery and more complications. Mechanism of injury conveys the energy transferred to the brain and helps predict injury patterns—from focal contusions to diffuse damage—affecting how severe the injury is likely to be. CT findings provide an objective snapshot of structural damage, such as hemorrhages, contusions, edema, or mass effect, which directly reflects injury burden and urgency of intervention. Together, these factors give a practical way to stratify severity and guide early management. While functional scales like the Glasgow Coma Scale with duration of loss of consciousness and post-traumatic amnesia are important, this combination emphasizes prognosis-related factors that are frequently used to classify severity in many clinical and research contexts.
