Although schizophrenia has traditionally been interpreted as a disorder of thought, contemporary perspectives suggest that it may be more appropriate to conceptualize it as a disorder of language connectivity. The linguistic anomalies present in schizophrenia possess distinctive characteristics that, despite certain connections, are not comparable to aphasic disorders. It is proposed that these anomalies are the result of dysfunctions in verbal self-monitoring mechanisms, which may influence other neuropsychological dimensions. This study set out to examine the neuropsychological dimensions associated with alterations in the neural networks of verbal self-monitoring in schizophrenic language, based on the scientific evidence published to date. Exhaustive searches were conducted in PubMed, Web of Science, and Scopus to identify magnetic resonance studies that evaluated verbal self-monitoring mechanisms in schizophrenia. Of a total of 133 articles identified, 22 were selected for qualitative analysis. The general findings indicated alterations in frontotemporoparietal networks and in systems such as the insula, amygdala, anterior cingulate cortex, putamen, and hippocampus. Despite the heterogeneity of the data, it is concluded that language plays a fundamental role in schizophrenia and that its alterations are linked with other neuropsychological dimensions, particularly emotional and perceptual ones.
尽管精神分裂症传统上被解释为一种思维障碍,但当代观点认为,将其概念化为语言连接障碍可能更为合适。精神分裂症中出现的语言异常具有独特的特征,尽管存在某些联系,但与失语症不同。有人提出,这些异常是言语自我监测机制功能障碍的结果,这可能会影响其他神经心理学维度。本研究旨在根据迄今为止发表的科学证据,研究与精神分裂症语言中言语自我监测神经网络改变相关的神经心理学维度。在PubMed、科学网和Scopus中进行了详尽的检索,以识别评估精神分裂症言语自我监测机制的磁共振研究。在总共识别出的133篇文章中,选择了22篇进行定性分析。总体研究结果表明额颞顶叶网络以及脑岛、杏仁核、前扣带回皮质、壳核和海马体等系统存在改变。尽管数据存在异质性,但得出的结论是,语言在精神分裂症中起着重要作用,其改变与其他神经心理学维度相关,尤其是情感和感知维度。
