Migraine comorbidity: from genotype to phenotype

Abstract

In this paper, we review the “current” and “ancient” concepts of comorbidity in migraine attack and disease. We emphasize the role of migraine as a complex disease and stress the appropriate consideration that genetic determinants require in modern taxonomy of migraine headaches. Novel attempts to revise migraine nosography should consider the complexity of genotype-phenotype-environment interactions in order to identify more rational approaches to treatment.
