Perioperative neurocognitive disorders(PND)are common perioperative diseases,which bring heavy burden to patients and society.Due to complex pathogenesis of PND and the lack of relia-ble diagnosis and intervention means,and electroencephalography(EEG)and magnetic resonance imaging(MRI)have the advantage of providing objective indicators,so their application in the study of PND has gradually become a hot topic.In this review,the intraoperative processed EEG indices,EEG spectral analy-sis,EEG functional connectivity analysis,EEG nonlinear dynamics analysis,and perioperative MRI analysis in patients with PND are reviewed,aiming to explore the clinical value of EEG and MRI in predic-ting and diagnosing PND.
