【摘要】：脑梗死后的语言功能是临床与基础研究关注的问题。传统认为梗死灶的部位是决定失语症表现的主要因素,并根据损伤部位将失语症分为不同的类型。然而,随着影像技术的发展,失语症的类型并不完全符合经典语言区解剖定位。此外,脑梗死后语言功能的恢复机制也尚未阐述清楚,其中最具争议的问题之一是大脑非优势半球语言功能镜像区在语言恢复中的作用。本文主要综述关于语言功能区定位及脑梗死后语言镜像区在语言恢复中作用的相关研究,阐明脑梗死后语言功能变化,为患者的康复治疗提供理论依据。
[Abstract]:Language function after cerebral infarction is a focus of clinical and basic research. Traditionally, the location of infarct is the main factor that determines the expression of aphasia, and the aphasia is divided into different types according to the location of injury. With the development of imaging technology, the type of aphasia does not completely accord with the anatomic localization of classical language area. In addition, the mechanism of recovery of language function after cerebral infarction has not been explained clearly. One of the most controversial issues is the role of the non-dominant hemispheric functional mirror region in language recovery. This paper reviews the research on the location of the language functional area and the role of the language mirror area in the recovery of language after cerebral infarction. To elucidate the changes of language function after cerebral infarction and provide theoretical basis for rehabilitation therapy.
