Mostofsky E, et al. - In this prospective cohort study, researchers assessed if migraine headaches were triggered by caffeinated beverage intake on the same or the following day. Every morning and evening, 101 adults with episodic migraine filled out electronic diaries. In March 2016-October 2017, 98 candidates (86 women & 12 men, mean age was 35.1 years) finished at least 6 weeks of diaries. Participants reported daily intake of caffeinated beverages, other lifestyle factors, and the timing and a description of each migraine headache. According to findings, there was a statistically significant nonlinear link between the consumption of caffeinated beverage and the likelihood of migraine headache that day. This indicates that on that day, elevated concentrations of consumption of caffeinated beverages can cause migraine headaches. By habitual intake and oral contraceptive use, associations varied.
