失用性失写症是一种书写障碍，尽管感觉运动功能、视觉反馈以及单词和字母知识正常，但字母和单词的实际正字法产生是异常的。我们报告一个病例，并回顾有限的临床解剖学文献。对现有病例的分析支持这一假设，即失读性失写症是由于空间和动觉调制运动的丧失而引起的几种相关临床疾病之一。它是由上级顶叶的病变引起的，通常在语言优势半球。
Apractic agraphia is an impairment in writing in which the actual orthographic production of letters and words is abnormal despite normal sensorimotor function, visual feedback, and word and letter knowledge. We report one case and review the limited clinicoanatomical literature. Analysis of available cases supports the hypothesis that apractic agraphia is one of several related clinical disorders that are due to the loss of spatially and kinesthetically modulated movements. it is produced by lesions in the superior parietal lobule, usually in the hemisphere dominant for language.
