Various modalities of six neuropsychological functions (graphia, calculia, finger gnosis, right-left orientation, praxia and constructive praxia) referred to as parietal or nonverbal have been investigated in the light of speech disorders. We examined 20 patients with brain lesion of vascular origin, who met the diagnostic criteria of mild and moderate dysphagia, 13 patients with Wernicke's and 7 with Broca's dysphasia. Verbal and nonverbal functions in patients with ischemic focuses of the speech area of the left hemisphere were investigated the Boston Diagnostic Aphasia Examination (BDAE). The investigation revealed that the presence and the type of mild and moderate dysphasia had a noteworthy role in pathoplasticity of correlated signs, thus implying in clinical practice a parietal lesion. Generally, poorer and at the same time more heterogeneous results were obtained in patients with Wernicke's dysphasia, mostly on calculia and right-left orientation. Finger agnosia was not considered as an authentic parietal sign, while each modality of graphia was impaired to a varying extent in speech disorders caused by presylvian and retrosylvian lesions. The paper also deals with the significance of lobulus parietalis inferior in speech.
针对言语障碍，人们已经根据被称为顶叶或非言语的六种神经心理功能（书写、计算、手指识别、左右定向、失用症和结构性失用症）的不同方式展开了研究。我们检查了20例血管源性脑损伤患者，这些患者符合轻度和中度吞咽困难的诊断标准，其中13例为韦尼克失语症患者，7例为布罗卡失语症患者。采用波士顿诊断性失语症检查（BDAE）对左半球言语区缺血灶患者的言语和非言语功能进行了研究。调查发现，轻度和中度失语症的存在及类型在相关体征的病理可塑性中具有显著作用，从而在临床实践中提示存在顶叶病变。一般来说，韦尼克失语症患者的结果更差且同时更具异质性，主要体现在计算和左右定向方面。手指失认症不被视为真正的顶叶体征，而在由颞叶前和颞叶后病变引起的言语障碍中，书写的每种方式都有不同程度的受损。本文还探讨了顶下小叶在言语中的意义。
