Which finding in a child with cyclic vomiting syndrome warrants referral for neurologic evaluation?

• A. Abnormal eye movements and mild ataxia
• B. Frequent vomiting without neuro signs
• C. Normal neurologic exam
• D. Headache only

Answer: (A)

Abnormal eye movements with mild ataxia signal involvement of the brain beyond the gut. Eye movements and coordination are governed by the central nervous system, especially the brainstem and cerebellum, so their disturbance during episodes raises concern for a neurologic or structural problem rather than a purely functional GI issue. That combination can indicate conditions ranging from complex migraines with neurologic features to more serious central nervous system processes, so it appropriately prompts a neurologic evaluation to look for treatable issues and guide management. Frequent vomiting without neuro signs, a normal neurologic exam, or headaches alone can occur with cyclic vomiting syndrome or primary headaches and do not by themselves mandate urgent neurology referral unless new red flags appear.
