Brain white matter hyperintensities in migraine: Clinical and radiological correlates

Abstract

Objective: Migraine is a recognised cause of brain white matter hyperintensities (WMHs) on magnetic resonance imaging (MRI). However radiological characteristics of those in migraine are not well defined. We sought to study the radiological characteristics and factors associated with WMH in migraine. Methods: Migraine patients who were investigated with MRI of the brain in the outpatient clinic were studied retrospectively. Two groups were delineated based on the presence or absence of WMH in MRI scans. The clinical and demographic characteristics between the two groups were compared to delineate the associations of WMH. Results: Forty four patients were studied, out of which 19 demonstrated..
