There is currently no effective treatment for VCI induced by CASO. Resveratrol, a type of polyphenol, improves cognitive performance in rat CASO models via pleiotropic effects. Furthermore, we previously reported the longevity gene, <jats:italic>SIRT1<\/jats:italic>, which can be activated by resveratrol, improves cognitive and cerebral blood flow impairment in mouse CASO models by activating endothelial nitric oxide synthase. However, clinical evidence remains limited.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>The REsveratrol for VAscular cognitive impairment investigating cerebral Metabolism and Perfusion (REVAMP) trial is a randomized, double-blind, placebo-controlled trial involving patients with asymptomatic CASO. Each participant will receive either 150\u2009mg\/day of resveratrol or a placebo for 35\u2009weeks. The primary objective is to determine whether resveratrol improves cognitive impairment, as assessed using the Alzheimer\u2019s disease Assessment Scale\u2013cognitive subscale 13. One of our secondary objectives is to determine whether resveratrol improves cerebral hemodynamic impairment as assessed via <jats:sup>15<\/jats:sup>O-gas positron emission tomography. We will recruit 100 patients (50 per group).<\/jats:p><\/jats:sec><jats:sec><jats:title>Discussion<\/jats:title><jats:p>The REVAMP trial may provide valuable insights into new therapeutic options, as
