Can autonomic dysfunction affect migraine?
Short answer
Yes. The autonomic nervous system is closely tied to migraine biology. Poor regulation of heart rate, blood pressure, and blood flow can amplify migraine frequency and severity.
More detail
Symptoms such as light-headedness with standing, heart racing on mild exertion, and post-activity crashes often coexist with migraine — particularly after concussion or prolonged illness — and can share underlying autonomic mechanisms.
Care that supports autonomic regulation is often adjunctive to migraine management, not a substitute for it.
