Which statement about Cantu grading is true?

Which statement about Cantu grading is true?

• A. It uses imaging to assign grades
• B. It uses LOC and PTA to assign grades
• C. It uses symptom duration only
• D. It uses age to adjust grades

Answer: (B)

Cantu grading is a clinical way to gauge concussion severity using what happened after the injury: whether there was any loss of consciousness and whether there was post-traumatic amnesia, and how those states persisted. Imaging isn’t used to assign grades because it doesn’t reliably reflect concussion severity and many concussions don’t show acute imaging changes. Symptom duration can inform monitoring and return-to-play decisions, but it isn’t the basis for the grade itself. Age isn’t a factor in this grading scheme. So, using loss of consciousness and post-traumatic amnesia to assign grades is the correct description.
