Details and patient eligibility

About

Headaches are extremely common illnesses with a combined lifetime prevalence of 90-99% in Europe. Despite this high prevalence, there are persons who have never, in their whole life, encountered a headache.

The aim of the study is to identify factors that protect against headache by studying multiomics in people who never have had a headache (headache resistant) versus non-resistant controls.

The investigators will measure multiomic changes (transcriptomics and metabolomics) after pain induction by Cold Pressor Test. 3 blood samples, two for RNA and one for metabolites are taken 5 minutes before a Cold Pressor Test and again 1 hour after the Cold Pressor Test.

The investigators hope to contribute with novelty to the current understanding of headache pathophysiology and development of more efficient treatment of headache.
