According to our clinical observations from various aspects of stroke patients, such as the total incidence of aphasia, the incidence of aphasia after left brain damage of the dextrals, the aphasia that occurs in patients without hemiplegia, and the types of aphasia, a much higher incidence of crossed aphasia is seen among the stroke patients of the Han (the largest ethnic group in China) as compared with the Uighur-Kazaks (U-K) in China and the Occidentals documented in the literature. Motor aphasia is most common and pure sensory or posterior aphasia is rarely seen in Han patients. The distinct features of the Chinese language is a possible explanation for this difference. We suspect that language function of the Han is not localized in the left brain but in the right or both hemispheres. There is no definite Wernicke's area in the left brain of the Chinese people and the neural pathway of the language function in the brain of the Chinese people is not similar to people who speak phonetic languages. Consequently the universal applicability of the theories of cerebral laterality of the language function and dominant hemisphere established by Dax and Broca are questioned in this paper.
根据我们对中风患者多方面的临床观察，如失语症的总发病率、右利手者左脑损伤后失语症的发病率、无偏瘫患者中出现的失语症以及失语症的类型，发现中国汉族（中国最大的民族）中风患者中交叉性失语症的发病率比中国维吾尔族 - 哈萨克族（维 - 哈族）以及文献记载的西方人群要高得多。运动性失语症最为常见，汉族患者中纯感觉性或后部失语症很少见。汉语的独特特征可能是造成这种差异的一个原因。我们怀疑汉族人的语言功能并非局限于左脑，而是在右脑或双侧半球。中国人左脑没有明确的韦尼克区，中国人脑内语言功能的神经通路与说拼音语言的人不同。因此，本文对达克斯和布罗卡建立的语言功能大脑偏侧化及优势半球理论的普遍适用性提出了质疑。
