Evaluating EEG Features for Predicting Cognitive Disorders After Heart Surgery

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to investigate how electroencephalography (EEG) features can predict the occurrence of perioperative neurocognitive disorders in patients undergoing cardiovascular surgery with general anesthesia. Data will be collected using a standard 32-channel EEG cap, and cognitive assessments will be performed before and after the surgery using the Montreal Cognitive Assessment (MoCA). The study will analyze preoperative and postoperative EEG brain network-related indexes to identify potential predictive markers for cognitive decline following surgery.
