In contrast to the classic form of alexia without agraphia, subangular alexia results from a single lesion located deep in the white matter of the left parietal lobe. In the present report, a patient with subangular alexia and features of mixed transcortical aphasia is described. Neurolinguistic findings include: alexia without agraphia, paucity of spontaneous speech, moderate auditory comprehension difficulty, excellent repetition, echopraxia, colour agnosia, and naming disorder. Neurolinguistic tests revealed intact phonological organisation and grammatical filter." Our studies revealed a "double disconnection syndrome," the co-existence of two relatively rare neurobehavioural disorders. Furthermore, the studies reported here clearly show dissociations of language functions in both the visual and auditory modality, which demonstrates that the stages of language processing are separable.
与经典型失读不伴失写症不同，角回下失读症是由位于左侧顶叶白质深部的单个病灶引起的。在本报告中，描述了一名患有角回下失读症和混合性经皮质失语症特征的患者。神经语言学发现包括：失读不伴失写、自发言语匮乏、中度听觉理解困难、复述良好、模仿动作、颜色失认和命名障碍。神经语言学测试显示语音组织和语法筛选功能完好。我们的研究揭示了一种“双重分离综合征”，即两种相对罕见的神经行为障碍并存。此外，这里报告的研究清楚地表明了语言功能在视觉和听觉模式上的分离，这证明了语言处理阶段是可分离的。
