Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Cognitive levels were assessed 1 day before surgery and 1 week after surgery (7±2 days) using the Montreal Cognitive Assessment (MoCA) . Patients were followed up one month (30±2 days) after surgery using the Telephone version of the Montreal Cognitive Assessment Scale (T-MoCA).
Preoperative and postoperative electroencephalography brain network-related indexes (such as cluster coefficient, small world index, etc.) in patients with PND will be included in the analysis.
