[Review of the Austrian field study on headache (author's transl)].

In our field study on headache we made use of individual medical interviews and of an anterospectively programmed inventory designed for computer analysis. With regard to this aspect our investigation is the first of its kind in literature. We could find some new aspects concerning etiology and therapy of headache, among others the importance of the factor "unstable hypotension" in a general state of vascular lability, and of the factor of manual labour as a prophylactic aid against headache. Furthermore, evidence concerning the general incidence and the varying morbidity in different professional and social groups could be collected.
