Postoperative cognitive dysfunction is a kind of obstacle in the thinking process, so far there is no effective treatment and prevention means.More and more attention has been paid to reduce the occurrence of postoperative cognitive impairment and promote the recovery of postoperative cognitive function and some studies have found that cognitive reserve can be used as a preventive measure for POCD.We reviewed foreign literature to elucidate the pathophysiological mechanisms of POCD and cognitive reserve and to summarize their correlation. The effectiveness and mechanism of cognitive reserve in the treatment of POCD were analyzed to provide reference for the clinical treatment and prevention of POCD.
