交叉性失语是一组由于右利手者右侧大脑半球损伤引起的获得性语言障碍综合征，在卒 中患者中的发病率为0.38%～4.6%，包括镜像失语与非典型失语，口语表达障碍多数为非流利性失语。 交叉性失语的发病机制目前仍存在争议，越早进行康复训练，预后越好。本文从交叉性失语的发病 机制、临床特点、影像学检查及康复训练的研究进展进行综述，以提高临床医师的重视，从而为交 叉性失语的诊治提供理论依据。 Abstract: Crossed aphasia (CA) refers to aphasia occurring after right cerebral hemisphere injure in right-handed individuals. The incidence of CA in stroke patients is 0.38%-4.6%. CA includes mirror image crossed aphasia and anomalous crossed aphasia, and impaired oral expression mainly presented with non-fluent aphasia.
