[Pathophysiology and Outcome of Asymptomatic Moyamoya Disease].

The widespread use of non-invasive imaging techniques has increased the detection of asymptomatic Moyamoya disease. AMORE, a prospective study launched in 2012, suggests that asymptomatic cases can present with silent infarctions or hemorrhages and have a high risk of cerebrovascular events and disease progression. Thus, strict management of lifestyle-related diseases and regular follow-up imaging are essential. Antiplatelet agents should be used cautiously because of the risk of intracranial hemorrhage. The effectiveness of cerebral revascularization surgery remains unclear.
