Which of the following is a symptom of a concussion?

• A. Headache
• B. Dizziness
• C. Confusion
• D. All of the above

Answer: (D)

Concussions produce a range of symptoms that can affect physical, cognitive, and balance systems. A headache is a common physical symptom, dizziness reflects vestibular disruption, and confusion indicates cognitive impairment. Because each of these can occur after a concussion, recognizing that multiple symptoms may be present makes the best answer “All of the above.” In practice, this means if an athlete reports any of these after a head impact, they should be removed from play and evaluated, and they should not return until cleared by a medical professional. While any single symptom can occur in isolation, the typical pattern often includes more than one, so acknowledging all of them covers the common presentation.
