The case of a female dextral patient (MN) is reported. MN sustained a partial frontotemporal infarction in the right hemisphere. Clinically, MN presented herself mainly with aphasic symptoms. The dextrality of the patient and the laterality of the lesion as well as the nature of language deficits would legitimate the diagnosis of a crossed aphasia, implying paradoxical lateralization of language in MN. However, comprehensive neuropsychological assessment revealed the presence of a global dysexecutive syndrome in MN, suggesting a general cognitive impairment, part of which must be the aphasic symptoms. General issues regarding the relationship between language and cognition and the lateralization of cognitive functions are discussed.
报告了一例右利手女性患者（MN）的病例。MN右侧半球发生部分额颞叶梗死。临床上，MN主要表现为失语症状。患者的右利手、病变的侧别以及语言缺陷的性质使交叉性失语的诊断合理，这意味着MN的语言存在矛盾的偏侧化。然而，全面的神经心理学评估显示MN存在全面的执行功能障碍综合征，提示存在一般认知损害，其中部分损害必定是失语症状。本文讨论了语言与认知之间的关系以及认知功能偏侧化的一般问题。
