In the MMD subgroup (n=187), advanced MMD had an independent positive association with the total WMH volume (0.120 [0.035]; p<0.001), periventricular WMH volume (0.110 [0.031]; p<0.001), and periventricular-to-subcortical ratio (0.139 [0.038]; p<0.001). Periventricular WMH volume (adjusted hazard ratio [95% confidence interval], 5.12 [1.26–20.79]) and periventricular-to-subcortical ratio (3.80 [1.51–9.56]) were associated with future ischemic events in medically followed-up MMD patients. However, no demonstrable association was found between subcortical WMH volume and MMD, MMD severity, or future ischemic events.DiscussionPeriventricular WMH, but not subcortical WMH, may represent the main pathophysiology of MMD. Periventricular WMH may be used as a marker for ischemic vulnerability in patients with MMD.
