Official Title: Neurocognitive and Radiological Assessments in Adult Patients With Moyamoya Disease Undergoing Surgical Revascularization
Brief Summary:
Adult patients with moyamoya disease (MMD) are reported to suffer from considerable impairment of executive function/attention. Although reduced cerebrovascular reserve (CVR) in frontal areas has been detected by perfusion MRI and then confirmed to be associated with executive dysfunction in adult MMD, the structural and functional changes is still unclear with progression of executive dysfunction. Furthermore, it is very important to study the association between the neurocognitive and radiological improvement after surgical revascularization, so as to help detecting cerebral regions which are involved in executive deterioration or improvement after surgery. Then the investigators can determine whether these regions can be used as indicators to decide rational therapeutic schedule and timing of adult MMD with executive dysfunction.
Thus the aim of this study is to primarily find out the neuropsychological and radiological correlates in adult MMD, and then to quantitatively evaluate the effectiveness of surgical revascularization in prevention of executive dysfunction in adult MMD.
