Abstract: This paper discussed the classification, performance, cerebral localization and the possible mechanism of agraphia in patientswith aphasia. Writing disorders include not only agraphia caused by the neurological dysfunction of the brain, but also mechanicalwriting 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 languagesystems. Therefore, foreign research methods are not suitable for us. Domestic studies on agraphia are mostly case reports, and researchmethods and the pathological mechanism of Chinese agraphia are not consistent.
