Headache determination by meteorotropic influences.
Using the biometeorologic system proposed by Brezowsky, the chronological distribution of migraine attacks was analysed in 4 patients over a 5-year period. A correlation of complaints with physical indices (atmospheric pressure, temperature, humidity and ionisation) could not be established. However, a significantly high incidence of headache symptoms was shown in the biometeorologic phase 6Z (although other investigators have reported such an increase in weather phases 3 and 4). The important common denominator of these weather phases seems to be a disturbed circadian rhythm which interferes with endogenous biorhythms and triggers attacks of headache.
