What red flags indicate a concussion that requires urgent medical evaluation?

• A. Worsening confusion, repeated vomiting, loss of consciousness, slurred speech, seizures, severe or worsening headache, neck pain, focal neurologic signs.
• B. Mild headache that resolves with rest.
• C. Occasional dizziness that resolves in an hour.
• D. Temporary memory lapse after exercise only.

Answer: (C)

The key concept is recognizing red flags after a concussion that signal a potentially serious brain or neck injury and require urgent medical assessment. Signs like worsening confusion or agitation, repeated vomiting, loss of consciousness, slurred speech, seizures, a severe or worsening headache, neck pain, or new focal neurologic signs (such as weakness or numbness on one side, trouble speaking) suggest ongoing or expanding injury and need prompt evaluation, often in an emergency setting.

In contrast, symptoms such as a mild headache that improves with rest, dizziness that resolves within an hour, or a brief memory lapse after exercise are not red flags on their own and don’t automatically require urgent medical care, though they should be watched for any changes or new symptoms. If any red flags appear or symptoms worsen, seek medical attention right away.
