Application of electroencephalography in the management of postoperative cognitive dysfunction

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 reflects 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.
