PREVALENCE AND HEREDITY OF MIGRAINE AND MIGRAINOID HEADACHES AMONG 461 DANISH DOCTORS

The reason why doctors were preferred as subjects in the present investigation is twofold; firstly, the diagnostic reliability to be obtained via questionnaires would thus be higher than that otherwise obtained in populations of a different composition; secondly, the obtained data might be comparable with the findings concerning prevalence and heredity recently published by Dalsgaard-Nielsen, Engberg-Pedersen and Holm3 who personally interviewed members of a mixed population.
