About this study

The purpose of this clinical study is to better understand the function of the autonomic nervous system in patients with migraine. We aim to understand whether the autonomic functions change depending on the migraine status (i.e. whether they are between or during attacks) and whether the CGRP monoclonal antibody (mAb) class of drugs affects the autonomic functions. The aim is not to investigate the effect of CGRP-mAb on migraine frequency. Calcitonin gene-related peptide (CGRP) is a neurotransmitter in the nervous system that plays an essential role in the development of migraine headache. Monoclonal antibodies can block the function of this messenger substance. Several studies have shown that this blockade leads to a reduction in the frequency of migraine. In addition to its role in migraine, CGRP also acts on the blood vessels and the autonomic nervous system. The autonomic nervous system is responsible for everything we have no control over in our body. This includes everything from heart rate and blood pressure to our digestion.
