title: Headache-related disability among medical students in Amazon: a cross-sectional study.
abstract: OBJECTIVE
  To evaluate the prevalence of headache in medical students, and quantify the degree of disability through HIT-6 and MIDAS SCALE.
  
  
  METHODS
  The criteria established by International Headache Society were used and the HIT-6 and MIDAS, to asses disability.
  
  
  RESULTS
  140 medical students from UFAM were evaluated. 16.43% cases of migraine headache, 6.43% of probable migraine, and 23.57% of tension headaches were detected. 6.42% reported an absence of headache; and another 11.42% had secondary headache. According to the HIT-6 questionnaire, in 7.14% and 18.57% of the students, headaches were classified as having substantial to severe impact, respectively.
  
  
  CONCLUSIONS
  Migraine and probable migraine had higher scores than the other types of headache and, therefore, led to higher levels of disability. The present study did not find a significant correlation between student semester, age or extracurricular activities on the impact generated by headache.
