To examine the different aspects of language and its representation in the brain.
Apractic agraphia, a form of mechanical agraphia, is produced by lesions in the left superior parietal lobe. However, little is known about the dissociation between allographic level representations for cursive writing and printing.
A 78-year-old right-handed patient with a history of transient ischemic attack was evaluated by interview, neurologic and neuropsychiatric examination, neuropsychologic testing, speech and language evaluation, and functional neuroimaging (single photon emission computed tomography).
The patient exhibited a disorder strictly limited to cursive writing resulting from ischemic damage to parietal and occipital lobes bilateral.
These findings support the assertion that printing and cursive writing are represented differentially and an isolated deficit in any of them can be the only presentation of disorder of language organization, secondary to brain damage in left superior parietal area.
研究语言的不同方面及其在大脑中的表征。
失用性失写症是机械性失写症的一种形式,由左侧顶上叶病变引起。然而,关于草书书写和印刷的异体字水平表征之间的分离知之甚少。
对一名78岁有短暂性脑缺血发作病史的右利手患者进行了访谈、神经和神经精神检查、神经心理学测试、言语和语言评估以及功能神经影像学检查(单光子发射计算机断层扫描)。
该患者表现出一种严格限于草书书写的障碍,这是由双侧顶叶和枕叶的缺血性损伤所致。
这些发现支持以下观点,即印刷和草书书写的表征不同,其中任何一种的孤立缺陷都可能是语言组织障碍的唯一表现,继发于左侧顶上叶区域的脑损伤。
