Abstract

Background A detailed evaluation of migraine aura symptoms is crucial for classification issues and pathophysiological discussion. Few studies have focused on the detailed clinical aspects of migraine aura. Methods We conducted a prospective diary-based study of migraine aura features including presence, quality, laterality, duration of each aura symptom, their temporal succession; presence of headache and its temporal succession with aura. Results Seventy-two patients completed the study recording the characteristics of three consecutive auras ( n = 216 auras). Visual symptoms occurred in 212 (98%), sensory symptoms in 77 (36%) and dysphasic symptoms in 22 (10%). Most auras had more than one visual symptom (median 2, IQR 1-3, range 1-4). The majority of patients (56%) did not report a stereotyped aura on the three attacks with respect to visual features, the combination and/or temporal succession of the three aura symptoms. Fifty-seven percent of patients also reported a different scenario of temporal succession between aura and headache in the three attacks. Five per cent of aura symptoms were longer than four hours. Conclusion These findings show a high inter- and intravariability of migraine with aura attacks. Furthermore, they provide reliable data to enrich and clarify the spectrum of the aura phenotype.
