P060. Vitamin D deficiency in episodic migraine, chronic migraine and medication-overuse headache patients

Abstract

Background Various studies have hypothesized a common inflammatory pathogenesis for headache and hypovitaminosis D (HD), showing that migraine patients have low levels of vitamin D [1]. Other studies did not confirm this [2]. Recently, a relationship between HD and reduced pharmacological response has been hypothesized, while vitamin D supplementary intake in HD patients may contribute to clinical improvement [3]. Aim of our prospective study was to evaluate the relationship between vitamin D levels and headache frequency and management in a cohort of patients accessing to our Centre for Headache from April 2015 to October 2015. We present preliminary data about patients enrolled until June 2015.
