title: [Menstrual headache: subtypes, clinical phenotypes and treatment].
abstract: BACKGROUND
  Up to 60% of women relate their episodes of headache to menstrual cycle. Menstrual migraine has been included in the second edition of the International Classification of Headache disorders. Menstrual tension-type headache has not yet been recognised by the International Headache Society.
  
  
  OBJECTIVE
  To evaluate the prevalence of different subtypes of menstrual headache and to analyze their clinical features and the treatment prescribed.
  
  
  METHODS
  We prospectively included women attending several neurology outpatient clinics, from January to November 2008 whose headache appeared during the menstrual period.
  
  
  RESULTS
  A total of 108 patients were included during the study period. Mean age was 34.8 ± 8.9 years-old. 29.3% suffered from pure menstrual migraine, 58.7% from menstrual related migraine, 4.5% from pure menstrual tension-type headache and 7.5% from menstrual related tension type headache.
  
  
  CONCLUSIONS
  Our data suggest that menstrual related tension-type headaches exist with a prevalence found about 12%, in our neurology outpatient clinics.
