ABSTRACT
ABSTRACT Vertigo symptoms and subclinical vestibular dysfunctions may occur in migraine. The Minimal Caloric Test (MCT), an easy-to-perform, convenient and yet informative procedure was used to test the vestibular function in 30 vertigo-free migraine patients outside attacks and 30 paired controls. Although not statistically significant, a right-to-left nystagmus duration asymmetry greater than 25% was present in both groups. This difference was greater in the patients group, suggesting the presence of subclinical vestibular imbalance in migraine.
RESUMO
RESUMO Vertigem e alterações vestibulares subclínicas têm sido identificadas na enxaqueca. O teste calórico mínimo é simples de realizar, informativo e conveniente. Ele foi realizado em 30 pacientes com enxaqueca sem queixa de vertigem e 30 controles pareados. Embora não estatisticamente significativo, ocorreu assimetria direita-esquerda superior a 25% na duração do nistagmo em ambos os grupos, maior nos pacientes, o que sugere a presença de desequilíbrio vestibular subclínico na enxaqueca.
