 The number of elderly people who may need surgical intervention will significantly rise as the population ages. Cognitive function is highly vulnerable to surgery and/or anesthesia;perioperative neurocognitive disorders, including acute postoperative delirium(POD), are more frequent in the elderly. Evidence suggests a close relationship between the development of POD and the increasing risk of subsequent persistent cognitive decline, including dementia. Hence, preventing POD may improve elderly patients’ postoperative quality of life. On the other hand, POD pathogenesis is complex and related to the aging process, for which there is no specific treatment. Currently, non-pharmacological interventions are recommended with demonstrated dose-dependent effectiveness. Although urgent surgery is common among elderly patients, there are time constraints particularly before surgery. However, a multidisciplinary team should implement all possible measures during each phase of the perioperative period. Therefore, it is desirable to improve the quality of medical care for the elderly in daily clinical practice. Here, we present the current status of POD pathogenesis and putative biomarkers for early detection and will focus on the preventive strategy to reduce POD, especially in urgent surgery.
