Chronic recurrent headaches may constitute the neurologic presentation of EDS in the absence of structural, congenital or acquired CNS lesions that correlate with their symptoms. Individuals with EDS may be prone to migraine due to an inherent disorder of cerebrovascular reactivity or cortical excitability. Additional studies are needed to elucidate the pathogenesis of headaches in EDS.
