[Migraine: differential diagnosis in episodic vertigo]

Abstract

Vestibular symptoms can be the predominant feature of migraine both in children and adults. Attacks of spontaneous or positional vertigo lasting from minutes to days may occur with or without concomitant headache. In the literature three syndromes of vestibular migraine have evolved: basilar artery migraine, benign recurrent vertigo and benign recurrent vertigo of childhood. In clinical practice, however, variants seem to be more frequent than the pure syndromes. Diagnosis is based on the individual constellation of typical precipitants and symptoms of migraine and the efficacy of pharmacological migraine prophylaxis. Nine cases are presented.
