Understanding how CGRP affects autonomic function in migraine patients

Autonomic Functions in Migraine Patients as a Function of Migraine Status and CGRP Inhibition

Observational Medical University of Vienna · NCT04628429

This study is trying to see how a migraine treatment affects the nervous system in people with migraines, both during attacks and when they're feeling fine.

What this trial studies

This observational study aims to explore the role of the autonomic nervous system in patients suffering from episodic and chronic migraines. It will assess whether autonomic functions vary based on migraine status, such as during an attack or in between attacks, and how these functions may be influenced by CGRP monoclonal antibodies. The study will utilize standardized autonomic tests and scales to evaluate symptoms and gather data on the impact of CGRP inhibition on autonomic function. The findings could provide insights into the relationship between migraines and autonomic symptoms.

Who should consider this trial

Good fit: Ideal candidates include individuals with chronic or episodic migraines who have not responded to multiple prophylactic treatments.

Not a fit: Patients with a history of certain cardiovascular conditions or those who are pregnant or lactating may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance our understanding of migraine mechanisms and lead to improved treatment strategies for patients.

How similar studies have performed: While there have been studies on CGRP's role in migraines, this specific focus on autonomic function is relatively novel.
