Key clinical point: Habitual intake of caffeinated beverages may not increase headache frequency, duration, or intensity in patients with episodic migraine, contrary to popular belief.
Major finding : Compared with patients having episodic migraine who did not habitually consume caffeinated beverages, those who consumed 1-2 servings per day reported 0.3 (95% CI −2.0 to 2.5) more headache days per month, whereas those who consumed 3-4 servings per day reported 1.3 (95% CI −4.5 to 1.9) fewer headache days per month. Moreover, the headache duration and intensity did not differ across levels of caffeinated beverage intake.
Study details: This prospective cohort study evaluated the association between habitual caffeinated beverages intake and headache outcomes among 97 patients with episodic migraine (age ≥ 18 years).
