Three new studies explore preventing secondary stroke, a potential biomarker for MS prediction, and a link between vitamin D and headache.
Three new studies in neurology -- one in stroke, one in headache, and one in multiple sclerosis (MS) -- include: the diabetes drug pioglitazone can help prevent secondary stroke in those with abnormal glucose metabolism; men with low blood levels of vitamin D have a higher risk of frequent headaches; and a biomarker may predict which patients with clinically isolated syndrome (CIS) may develop MS.
