State-dependent facial pulsation asymmetry and phase asynchrony measured by imaging photoplethysmography and their coupling with contingent negative variation in migraine
To characterize imaging photoplethysmography (iPPG)-derived facial hemodynamic alterations across migraine states and examine their association with contingent negative variation (CNV).
Key Findings:
Bilateral pulsation amplitude asymmetry (BPA) and bilateral pulsation phase difference (BPP) were higher in migraine patients compared to healthy controls.
Interictal phase participants exhibited higher CNV amplitudes and areas than both healthy controls and migraine attack phase participants.
CNV amplitudes positively associated with BPA and BPP, with angiosome-dependent slopes.
Interpretation:
Remove this section as it contains unsupported conclusions.
Limitations:
Findings require validation in larger, longitudinal, and external cohorts.
Potential confounding factors such as mood symptoms and acute medication use were considered but may still influence results.
Conclusion:
Revise to eliminate unsupported claims and focus on findings directly stated in the source.
