原文：皮质下缺血性脑血管疾病（subcortical ischemic vascular

disease,SIVD）是一组以小血管病变为主要病因、以皮质下多发性腔隙性梗死和脑白质病变为主要脑部损害的缺血性脑血管病，是引起血管性认知功能损害（vascular cognitive impairment，VCI）最常见的亚型。SIVD可引起步态障碍，如帕金森样步态、共济失调性步态、走路不稳或无明显诱因的频繁跌倒，有研究表明，步态异常可能是血管性痴呆的早期标志。本文将从SIVD导致步态障碍的病理机制、步态障碍类型、步态障碍与认知损害关系、步态障碍的分析与评价、治疗等方面进行综述。

Subcortical ischemic vascular disease（SIVD）is a case of ischemic cerebrovascular disease, the leading cause of which is small vessel lesions, and the subsequent main damages to the brain are subcortical multiple lacunae infarct and leukodystrophy; it is the most common subtype that causes vascular cognitive impairment (VCI).

SIVD可引起步态障碍，如帕金森样步态、共济失调性步态、走路不稳或无明显诱因的频繁跌倒，有研究表明，步态异常可能是血管性痴呆的早期标志。本文将从SIVD导致步态障碍的病理机制、步态障碍类型、步态障碍与认知损害关系、步态障碍的分析与评价、治疗等方面进行综述。

SIVD can induce gait disorder, such as Parkinson gait, ataxic gait, ataxia or frequent tumbles without obvious causes; research shows that abnormal gait may be early signs of vascular dementia. From the pathological mechanism of gait disorder caused by SIVD, this paper describes the types of gait disorder, the relationship between gait disorder and cognitive impairment and the analysis, evaluation as well as the treatment of gait disorders.
