Abstract Several reports document crossed aphasia following a right cerebral infarct. However, few of them provide a detailed investigation of associated neuropsychological disorders. A personal neglect disorder with no difficulty in orienting attention in the contralesional space has not been frequently reported independently of lesion side for the language deficit. In most cases, the deficit is described in the acute period. We report the case of a patient who showed severe crossed aphasia several months after cerebral damage. In addition to his language deficit, he suffered from finger agnosia, acalculia, and right/left confusion. Although he was able to orient attention in the contralesional space, he had a persistent personal neglect disorder with severe difficulty in attending to his own body. Results suggest that right hemisphere language dominance does not preclude ipsilateral specialisation for other functions. Furthermore, the dissociation between the two spatial functions provides further confirmation that they are subserved by two independent systems.
摘要 有几份报告记录了右侧脑梗死继发交叉性失语的情况。然而，其中很少有对相关神经心理障碍进行详细调查的。一种在对侧空间定向注意力无障碍的个人忽视障碍，独立于语言缺陷的病变侧而被频繁报道的情况并不多见。在大多数情况下，这种缺陷是在急性期描述的。我们报告了一例患者，其在脑损伤数月后出现严重的交叉性失语。除了语言缺陷外，他还患有手指失认症、失算症和左右定向障碍。尽管他能够在对侧空间定向注意力，但他存在持续的个人忽视障碍，在关注自身身体方面有严重困难。结果表明，右侧半球语言优势并不排除同侧在其他功能上的特化。此外，两种空间功能之间的分离进一步证实它们由两个独立的系统所支持。
