Tracking the evolution of non-headache symptoms through the migraine attack

The migraine attack is classically divided into the prodromal, aura, headache and postdromal phase. Previous studies have highlighted non-headache symptoms associated with migraine occurring during the prodromal or postdromal phase. This study aimed to track the evolution of non-headache symptoms throughout all phases of the migraine attack. We also wished to delineate the phenotype of patients with more symptomatic migraine episodes and explore the association between non-painful symptoms and migraine disease activity and patients' disability.
