Which sign requires immediate medical referral during concussion evaluation?

• A. Worsening confusion
• B. Repeated vomiting
• C. Seizures
• D. Neck pain

Answer: (A)

Worsening confusion signals that brain function is deteriorating after a concussion, which can indicate ongoing injury such as swelling or bleeding. This kind of cognitive decline can progress quickly, so directing the person for immediate medical evaluation is essential to assess and manage the risk of serious complications. Other red flags like repeated vomiting, seizures, or neck pain are also important and require urgent care, but they don’t as directly reflect a decline in brain function. The key point is that increasing confusion is the most urgent cue to seek prompt professional assessment.
