To investigate the association between chronotype and migraine-related disability in patients with migraine.
Key Findings:
Migraine patients exhibited poorer sleep quality (PSQI: 7.28 vs. 4.37, p < 0.001).
Chronic migraine (CM) patients showed the highest disability (MIDAS: 36.17 vs. 9.63, p < 0.001).
No significant difference in chronotype distribution was observed between groups (p = 0.48).
Morning chronotypes had lower MIDAS scores compared to intermediate and evening types, though differences were non-significant (p = 0.082).
Interpretation:
Chronotype does not directly correlate with migraine-related disability; however, poor sleep quality in migraine patients, particularly those with CM, is noted.
Limitations:
The study was observational and cross-sectional, limiting causal inferences.
Self-reported questionnaires may introduce bias.
Conclusion:
The findings indicate that while chronotype may not directly influence migraine-related disability, the association with sleep quality warrants further investigation.
