Intracerebral hemorrhages in CADASIL.

Intracerebral hemorrhage (ICH) has been described only sporadically for patients with cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL). However, cerebral microbleeds (CMBs) were found in 31% to 69% of the patients with CADASIL, and this predicted an increased risk of ICH. In this study, the authors found that 25% of the symptomatic patients with CADASIL had ICHs, and their development was closely related to the number of CMBs.
