Sara, a 27-year-old woman with no significant past medical history, presents with confusion and a brief loss of consciousness following a minor car accident. What is the most definitive indication that Sara has suffered a concussion?
She experiences headaches that last for several weeks after the incident.
Sara remembers every detail of the accident.
A CT scan shows no cerebral edema.
Sara's Glasgow Coma Scale score is 15.
The Correct Answer is C
A. Headaches are a common symptom of concussion but are not the most definitive indication since it can occur due to other causes.
B. Sara remembering every detail of the accident does not exclude the possibility of a concussion, as some people may have intact memory despite having a brain injury.
C. This indicates that there is no swelling or bleeding in the brain, which is a hallmark of concussion.
D. While a GCS score of 15 suggests normal neurological function, it is not as definitive as a CT scan in ruling out cerebral edema or other brain injuries.
