With the global aging population undergoing more surgical procedures, POD has emerged as a serious complication in surgical patients that can prolong hospital stays and increase the risk of developing Alzheimer's disease. The study utilizes an innovative VR system that combines eye-tracking cognitive assessment with interactive rehabilitation games to evaluate and train patients' cognitive function before non-cardiac and non-intracranial operations. Conducted at Peking University Third Hospital and First Hospital, this research specifically targets patients undergoing general surgery, orthopedic surgery and other non-intracranial\u002Fnon-cardiac procedures to determine if this technology-based intervention can effectively reduce POD incidence in this population while exploring its underlying mechanisms. The findings could lead to a practical solution for protecting cognitive health in elderly patients undergoing routine surgical procedures during recovery",[80,81],"Postoperative Delirium (POD)","Cerebral Small Vessel Diseases",[83,84,85,86],"postoperative delirium","cerebral small vascular disease","virtual reality","cognitive function","NOT_YET_RECRUITING","2025-05-22",{"date":90,"type":91},"2025-05-31","ACTUAL",{"date":90,"type":74},{"date":94,"type":74},"2027-12-31",{"name":5,"class":6},2]
