后部失语症患者的书写障碍

Writing disturbance of patients with posterior aphasia

分析５２例后部失语患者的书写障碍，书写检查包括写姓名地址、抄写、系列写数、听写、看图写及写短文。５２例均有书写障碍，且后３项的书写障碍比前３项严重。汉字词的书写障碍主要是构字障碍和字词错写。构字障碍表现为部分完成、部分代替、笔画添加或遗漏和新字；字词错写是以另一字代替作业要求写的字，包括近形、近音、近义或无关字代替。字词的书写障碍可能与汉字形为镶嵌结构和对字形的回忆障碍有关。

Analysis the writing disturbance of 52 patients with posterior aphasia.Writing tests included writing one s name and address.copying,writing number 1～21,dictating.writing confrontation naming from piotures.and writing about the state of illness.All patients had writing disturbance.The degree of writing disturbance of the latter three subtests of 52 patients was severer than that of the former three.Writing disturbance of Chinese characters included dysorthography and paragraphia.The dysorthograpg presented partial completion,partial substitution,extra or missing strokes,and neograph.Paragraphia presented that the target character was substituted by another one which was similar sound,similar form,similar meaning or unrelated with the target.The mechanism of writing disturbance might be related to the mosaic construction of Chinese idiographs,and to be inable to recall of character form.
