进食障碍患者注意偏向及抑制控制的事件相关电位研究(综述)

A review of studies on event-related potentials of attentional bias and inhibitory control in patients with eating disorders

进食障碍是一类易复发、疾病负担重的慢性疾病。进食障碍患者存在与执行功能相关的神经认知缺陷,其中最主要的表现是注意偏向及抑制控制的异常。随着事件相关电位研究的发展,进食障碍患者认知异常背后的神经机制得以被探究。本文回顾了近年来进食障碍患者注意偏向以及抑制控制两方面相关的事件相关电位研究,为基于神经认知机制诊疗方案的发展提供了参考。

Bating disorders(EDs)are a kind of chronic disease with high relapse rate and heavy disease burden.Patients with EDs have neurocognitive deficits related to executive function,among which the main manifestations are abnommal attentional bias and inhibitory control.Event-related potential studies are being undertaken to explore the underlying neural mechanism of cognitive abnormalities in EDs.This paper reviews the research of event-related potentials in EDs from the aspect of attentional bias and inhibition control.Suggestions for the future diagnosis and treatment programs based on neurocognitive mechanism are provided.
