[Epidemiology of vascular headache and migraine in the population of Warsaw].

An inquiry investigation carried out in a randomly selected group of adult population of Warsaw comprising 3 518 subjects showed that 37% of men and 68% of women (54% of the whole group) had headaches. The index of migraine prevalence (Mg) and vascular-tension headaches prevalence (Nbg) estimated on the basis of medical examination of 10% of the sample was 4% and 13% respectively in women and 2% and 6% respectively in men. For the whole sample this index was 3% and 10% respectively. The percent prevalence of Mg and Nbg among patients complaining spontaneously of headaches was 12% and 39% respectively, and among patients answering to questions about headaches this index was 6% and 19% respectively. On the basis of these results the prevalence of Mg and Nbg in the general population was calculated. No greater prevalence of Mg was found among epileptics and first-degree relatives of epileptics.
