“…Several studies demonstrated the association between the WMH burden and the frequency of pain attacks 13,14,18 , duration of disorder 11,19 , its progression over time 6,16,20 , the risk of ischaemic stroke 21,22 and CI 23 , while other studies did not establish any relationship between WMH and severity or duration of migraine 4,[24][25][26] , risk of stroke and other vascular events 11,24 , CI 9,16,27,28 , and progression of WMH over time 29 . WMH in patients with different types of migraine are predominantly located within the frontal and parietal lobes 9,12,13,18,26,[30][31][32] , in deep and periventricular 6,8,10,13,26 , and sometimes juxtacortical white matter 20,31,32 , with sizes varying from small single to con uent larger lesions 20,[30][31][32] .
