Abstract:

Introduction: As the most important and frequent type of headache found in children, migraines are responsible for chronic headache, abdominal pains and vomiting. Objective: To characterize the vestibular function in children with normal hearing diagnosed with migraine. Method: 17 children with normal audiometry and migraine underwent electronystagmography (ENG). Results: The most frequent symptoms were dizziness, nausea and vertigo. Alterations were observed only in the caloric test: asymmetric labyrinth preponderance and directional preponderance of nystagmus and hyperactive caloric responses, the most common occurrence. No observation suggested central disorders. Conclusion: Children diagnosed with migraine showed mostly the occurrence of irritative peripheral vestibular syndrome due to hyperactive caloric responses in the ENG.
