Defining migraine days

A correct and standardized definition of a migraine day is important for clinical and research purposes. In our new article published in the scientific journal Cephalalgia, we compared different definitions of a migraine day using data from headache E-diaries of 1494 migraine patients.

Based on the results, we recommend defining a migraine day as a day on which at least one of the following three criteria is met:

headache lasting at least 30 minutes with at least two of the four migraine characteristics;
a (visual) aura lasting 5-60 minutes;
or a day on which acute migraine-specific medication is used regardless of its effect.
