  1. Data are presented as means (SD) for continuous data and as n (% of column) for categorical data. DVP: disturbances of visual perception (i.e. blurred/foggy vision, ‘like looking through heat waves or water’, deformed images,…). . ^In the analysis, the authors dissected every visual into elementary disturbance as reported by Viana et al. 2017 (Cephalalgia 37: 979–989). *A and B can be referred to 1st and 2nd aura symptoms or 2nd and 3rd aura symptoms (67 auras had at least 2 symptoms, 14 auras had 3 symptoms). When two symptoms started simultaneously, we designated the first completing symptom as A
