In concussion grading by the American Academy of Neurology, which grade corresponds to confusion with no loss of consciousness for less than 15 minutes?

• A. Grade 1
• B. Grade 2
• C. Grade 3
• D. Grade 0

Answer: (A)

The idea being tested is how the American Academy of Neurology classified concussion severity based on loss of consciousness and how long symptoms like confusion last. In this scenario there is confusion but no loss of consciousness, and the confusion lasts less than 15 minutes. That combination corresponds to the mildest grade, Grade I. If confusion persisted longer than 15 minutes or there were any loss of consciousness, the grade would be higher (Grade II or Grade III, with loss of consciousness). Grade 0 would be reserved for no concussion symptoms at all, so it doesn’t fit when confusion is present. Grade I signals a mild concussion with transient symptoms, typically managed with rest and a careful return-to-play or return-to-activity plan as symptoms resolve.
