The Prevalence and Impact of Headache in Brazil
In Brazil, several epidemiological studies on headache have been produced, most with an emphasis on prevalence and the association of primary headaches with some sociodemographic characteristics of the population. Data on the burden of headache, however, are scarce. The aim of this paper is to review all Brazilian population‐based studies on headache, as well as to analyze the Migraine Disability Assessment Score (MIDAS) data collected with the PhD thesis of the senior author (LPQ).
