Abstract: Approximately one-third of stroke patients experience post-stroke cognitive impairment(PSCI),which significantly impacts their quality of life and survival time.The clinical evaluations of PSCI mainly rely on subjective neurophysiological scales due to its complex pathogenesis and lack of reliable,objective diagnostic tools.However,electroencephalogram(EEG)and magnetic resonance imaging(MRI)could provide objective indicators for diagnosis of PSCI.Based on EEG,MRI and EEG-MRI fusion,this article reviews recent advances in the central mechanisms of PSCI,focusing on changes in brainwave spectrum,brain structure,brain network etc.,in order to explore the clinical values of EEG and MRI in predicting and diagnosing PSCI,enhance the understanding of its pathogenesis and provide a basis for accurate clinical diagnosis.
