Abstract

Introduction: The need for early intervention in psychosis has led to the search for useful biomarkers in its prediction, where the analysis of spoken language stands out for its easy obtaining and low economic cost. In this systematic review, we analyze the main speech disturbances in patients at ultra-high risk for psychosis (UHR), evaluating their prevalence and their relationship with transition to psychosis. Methods: A search was carried out in PubMed and Embase databases for studies in English or Spanish, as well as the reference lists of the articles found. Results: Of 140 articles identified, 15 were included. The variables of the language analyzed were Linguistic Cohesion, Semantic Coherence, Syntactic Complexity, Metaphorical Production, Emotional Prosody and Formal Thought Disorder (TFP). The prevalence found ranged between 21% and 85% for disturbances included within the TFP, with no prevalence measures for the rest of the variables. The global accuracy for UHR transition to psychosis ranged from 70% to 100% across studies. Conclusion: There is a wide range of speech disorders in UHR patients, where the TFP is the most studied one. The prevalence of these alterations seems to be high, especially with regard to TFP. The analysis of those speech alterations in UHR patients appears as an excellent tool to predict transition to psychosis, particularly through interview transcription and the use of Artificial Intelligence.

精神病高危心理状态下言语障碍的分析：一项系统回顾。

引言：对精神病早期干预的需求导致了在其预测中寻找有用的生物标志物，其中口语分析以其易于获得和低经济成本而突出。在这篇系统综述中，我们分析了超高精神病风险（UHR）患者的主要言语障碍，评估了其患病率及其与向精神病过渡的关系。方法：在PubMed和Embase数据库中搜索英语或西班牙语的研究，以及找到的文章的参考文献列表。结果：在140篇已鉴定的文章中，包括15篇。所分析的语言变量为语言衔接、语义连贯、句法复杂性、隐喻产生、情感韵律和形式思维障碍。TFP中包含的紊乱的患病率在21%至85%之间，其余变量没有患病率测量。在所有研究中，UHR转变为精神病的全球准确率在70%到100%之间。结论：UHR患者存在广泛的言语障碍，其中TFP是研究最多的一种。这些改变的发生率似乎很高，特别是在TFP方面。对UHR患者的这些言语变化的分析似乎是预测向精神病转变的一个很好的工具，特别是通过访谈转录和人工智能的使用。
