Acquired dysgraphia has been described as a disorder of graphemic selection and spatial temporal disorganization which can exist in isolation or as a component of a broader language or cognitive syndrome. There is little agreement on the locus of writing centers, although select areas within the left hemisphere have been suggested. We describe a patient who had dysgraphia after a right hemispheric stroke. He had no demonstrable signs of limb apraxia or visual field deficit, and only subtle signs of language impairment other than the writing disturbance. Treatment emphasized progressively more complex writing tasks which included the following: (1) written responses to picture/word stimuli, (2) word and sentence dictation, and (3) self-generated sentences and functional writing tasks. At discharge from the hospital the patient's writing was within normal limits. Our findings were similar to those described for a patient with a left hemispheric stroke who was primarily dysgraphic. We conclude that our patient's dysgraphia was a component of a subtle aphasia as well as a spatial temporal disorganization disorder.
获得性书写障碍被描述为一种字形选择和时空组织紊乱的病症，它可以单独存在，也可以作为更广泛的语言或认知综合征的一个组成部分。关于书写中枢的位置，目前尚无定论，尽管有人提出左半球内的某些特定区域与之相关。我们描述了一名在右半球中风后出现书写障碍的患者。他没有明显的肢体失用或视野缺损迹象，除了书写障碍外，只有轻微的语言障碍迹象。治疗重点是逐步增加书写任务的复杂性，包括以下内容：（1）对图片/单词刺激的书面反应，（2）单词和句子听写，以及（3）自我生成的句子和功能性书写任务。出院时，患者的书写能力恢复到正常水平。我们的研究结果与一名主要表现为书写障碍的左半球中风患者的情况相似。我们得出结论，我们这位患者的书写障碍是一种轻微失语症以及时空组织紊乱症的一个组成部分。
