Sundar & Karin G. Johnson Background The impact of circadian misalignment on patients with migraine due to clock transitions is not well understood. Our study investigated the immediate effects of standard time (ST) to daylight saving time (DST) transition on sleep and headaches in patients with migraines. Methods In this prospective observational study, 23 adults with episodic migraine were followed for 4 weeks (2 weeks before and 2 weeks after ST-DST transition on March 12, 2023). Headache variables were documented via diary, sleep data were collected using a Withings under-mattress tracker, and chronotype was determined through the Morningness-Eveningness Questionnaire. Results Despite the lack of significant difference in mean…
