RESUMEN
OBJECTIVES: To evaluate association between presence of time preference of headache attack and social jetlag and circadian preference in patients with migraine with or without aura. METHODS: A total of 50 patients of migraine with or without aura who visited for the first time at a single tertiary medical center were examined and interviewed about their sleep pattern on weekdays and weekends and whether they have time preference of headache attack during a day or not. Frequency of headache and measurement for disability of headache such as six-item Headache Impact Test and other sleep profiles such as sleep duration, sleep quality, daytime sleepiness, and insomnia severity were obtained by a booklet of questionnaire. RESULTS: In this pilot study, the time preference of migraine attack during a day was present in 42% among the participants. In the cross-sectional analysis, the group of presence of time preference of attack showed earlier circadian preference (1:36 am±282 min vs. 4:24 am±186 min, p=0.02) and lower social jetlag than the other group (0.4±0.8 hour vs. 1.4±2.2 hour, p=0.04). Other demographic characteristics and frequency and severity of headache was comparable between groups. CONCLUSIONS: Considering an individual circadian preference might be a strategy in integrated management of migraine.
