Is autonomic function altered in migraineurs during headache-free periods compared to controls?
Is autonomic function altered in migraineurs during headache-free periods compared to controls?
Autonomic function, as measured by cardiovascular reflexes and power spectral analysis of heart rate and blood pressure variability, appears normal in migraineurs during headache-free periods.
No takes yet. Share an insight, caveat, or question.
Autonomic function appears preserved interictally in migraine; supports normal sympathovagal balance but leaves open attack-phase or longitudinal changes.
Pierangeli et al. (1997) studied this question.
