Objectives
Narrative objectives1
Asymptomatic carotid artery stenosis/occlusion is not only a major causative disease of cerebral infarction, but also considered to be a causaive disease of vascular cognitive impairment even without cerebral infarction. However, no preventive or therapeutic measures for vascular cognitive impairment caused by asymptomatic carotid artery stenosis/obstruction have been established. Resveratrol, which is commercially available as a dietary supplement, is expected to activate endothelial nitric oxide synthase through activation of SIRT1, a longevity gene, and we will examine whether resveratrol is associated with maintenance of cerebral blood flow plus maintenance/improvement of cognitive function.
