【摘要】 本文主要对失语患者失写症的分类、表现、各型失写症的大脑定位以及失写症的可能机制进行综述。书写障碍不仅包括脑高级神经功能障碍所致的失写症,也包括初级运动功能受损导致的机械性书写障碍,而失写症是由于后天获得性脑损害所引起的书写功能受损或丧失。国外对于失写症的研究主要是针对拼音语系,而汉语为藏汉语系,因此国外的研究方法不适宜被我们直接搬用。国内对于失写症的研究多为个案研究,且研究方法并不一致,对于汉语失写症的病理机制也无统一定论。更多还原

【Abstract】 This paper discussed the classification,performance,cerebral localization and the possible mechanism of agraphia in patients with aphasia.Writing disorders include not only agraphia caused by the neurological dysfunction of the brain,but also mechanical writing disorders caused by the primary motor dysfunction.Agraphia is a damage or loss of writing capability caused by acquired brain damage.The study abroad on agraphia focuses on phonetic language.Chinese characters and alphabetic languages belong to different language systems.Therefore,foreign research methods are not suitable for us.Domestic studies on agraphia are mostly case reports,and research methods and the pathological mechanism of Chinese agraphia are not consistent.更多还原
