Highlights
● Maintaining anesthesia depth within speciffc ranges, as indicated by electroencephalography monitors, may reduce the risk of postoperative cognitive dysfunction.
● Quantitative analysis of electroencephalography data can provide insights into the characteristics of postoperative cognitive dysfunction, aiding in its early detection and diagnosis.
● Combining electroencephalography with functional magnetic resonance imaging may enhance the assessment of brain function and improve the accuracy of monitoring devices.

Abstract

Postoperative cognitive dysfunction (POCD) is a common postoperative complication in elder patients, elevating the risk of dementia, impacting patient prognosis, and adding to the socio-economic burden. Electroencephalography (EEG) enables the recording of brain electrical activity and reffects the state of consciousness. Changes in the electrogram may signal diverse pathological and physiological states. Currently, EEG and its associated monitoring devices are extensively utilized in clinical practice. This paper presents a thorough review of the use of EEG in POCD research, aiming to establish a more substantial foundation for the prediction and prevention of POCD.

Keywords: Electroencephalography, depth of anesthesia, postoperative cognitive dysfunction, postoperative neurocognitive disorder
