Abstract
Background As there are no biological markers, a detailed description of symptoms, particularly temporal characteristics, is crucial when diagnosing migraine aura. In ICHD-IIIbeta, migraine aura duration is considered normal when each symptom is no longer than one hour. A recent systematic review of the topic [1] did not find any article exclusively focusing on the duration of the aura. The pooled analysis of data from the literature on aura duration showed that visual symptoms lasting for more than one hour occurred in 6%-10% of patients, sensory symptoms in 14%-27% and dysphasic aura in 17%-60%. Here we investigated the duration of aura symptoms, using a prospective diary-aided approach.
