This study aimed to verify the existence of a double aphasia/apraxia dissociation. Apraxic patients without aphasia and aphasic patients without apraxia were included in a consecutive series of patients with cortical or subcortical CT documented vascular lesions in the left hemisphere. Of 699 patients, 10 were found to be apraxic but not aphasic and 149 aphasic but not apraxic. These findings indicate an aphasia/apraxia double dissociation. This suggests that praxis and language make use of two different, partly overlapping networks.
本研究旨在验证双重失语症/失用症分离的存在。无失语症的失用症患者和无失用症的失语症患者被纳入一系列连续的左半球有皮质或皮质下CT记录的血管病变的患者中。在699名患者中,发现10名患者有失用症但无失语症,149名患者有失语症但无失用症。这些发现表明存在失语症/失用症双重分离。这表明运动运用和语言利用了两个不同但部分重叠的神经网络。
