Research Status of the Long-latency Auditory Evoked Potential in Mild Cognitive Impairment and Alzheimer's Disease / 听力学及言语疾病杂志

ABSTRACT

The long-latency auditory evoked potential can not only reflect the passive sensory processing of sound signals in the brain,but also reflect the active cognitive processing of the brain in different task modes,so it is applied to the assessment of cognitive function.This article reviews the research status of exogenous components(P1,N1,P2)and endogenous components(MMN/N2a,N2b,P3a,P3b)in the long-latency auditory evoked po-tential in mild cognitive impairment and Alzheimer's disease,and provides some reference for those who carry out relevant research in China.
