Abstract: Silent brain infarction（SBI） is a kind of cerebral infarction which often has no definite stroke history，typical clinical symptoms and signs of nervous system dysfunction，and needs to be found by cranial imaging or autopsy.With the development of related studies，SBI has been proved to be not completely asymptomatic，it may manifest as non-specific neurological impairments in some patients such as dizziness，headache，sleep disorders，memory loss and so on.Moreover，a large number of clinical reports show that sleep disorders is a common complication after stroke，which often adversely affects the prognosis and quality of life of patients.As one of the types of stroke，SBI is also associated with sleep disorders.However，due to non-specific clinical characteristics，it is often ignored by clinicians，and sleep problems in SBI patients are even less concerned，and there is a lack of related research reports on the association between them at home and abroad.This article reviews the possible mechanism and negative effects of sleep disorders in SBI，to improve clinical concerns of this disease to achieve early diagnosis and treatment.

摘要： 无症状性脑梗死（SBI）是指常无明确的卒中史、典型的临床症状及神经系统阳性体征，需通过颅脑影像学或尸检发现的脑梗死。随着研究的深入，SBI已被证实并非完全无症状，部分患者可能存在头晕、头痛、睡眠障碍、记忆力下降等非特异性神经功能损害表现。同时，大量临床报道显示，睡眠障碍是脑卒中后常见的并发症，并常会对患者的预后和生活质量产生不利影响。SBI作为脑梗死类型中的一种，与睡眠障碍也存在一定的联系，但由于SBI的临床特征，本身常被临床医生忽视，睡眠问题便更不受关注，国内外也缺乏相关研究报道。因此，本文对SBI与睡眠障碍共病的可能发生机制以及可能伴发的负面影响进行了综述，以便提高临床医生对其的关注度，做到早期诊治。
