Which statement about mild TBI presentation is true?

• A. Amnesia about the event with no loss of consciousness can occur
• B. Loss of consciousness always occurs
• C. Imaging always abnormal
• D. Seizures always occur

Answer: (A)

Mild traumatic brain injury often presents with features like confusion and amnesia around the time of injury, and loss of consciousness is not required for the diagnosis. In fact, many people with a concussion are fully awake but cannot recall the event or have retrograde/anterograde amnesia for a period around the impact. Imaging can be normal in mild TBI, and seizures are not a constant or universal finding. So the statement that amnesia about the event with no loss of consciousness can occur accurately describes typical mild TBI presentations.
