Syntactic alexia is the inability to comprehend graphically presented sentences when the meaning depends on syntax. Although previously described in association with Broca's aphasia and attributed solely to the frontal lobe portion of the lesions, syntactic alexia has not been reported to accompany conduction aphasia. We studied three patients who had conduction aphasia from temporoparietal lesions and syntactic alexia. None of them had lesions in Broca's area. Broca's aphasics and our patients with conduction aphasia have a syntactic comprehension disturbance. Since Broca's aphasics and our patients have lesions that may extend into the supramarginal gyrus, we postulate that this area may be critical for comprehending syntax.
句法性失读症是指当句子含义取决于句法时，无法理解以图形方式呈现的句子。尽管此前曾有报道称句法性失读症与布罗卡失语症相关，且仅归因于病变的额叶部分，但尚未有报道称其伴随传导性失语症出现。我们研究了三名因颞顶叶病变而患有传导性失语症和句法性失读症的患者。他们均无布罗卡区病变。布罗卡失语症患者和我们的传导性失语症患者都存在句法理解障碍。由于布罗卡失语症患者和我们的患者的病变可能延伸至缘上回，我们推测该区域可能对句法理解至关重要。
