Summary

Considering the complex pathological mechanism and the poor treatment outcomes of schizophrenia, early detection and intervention gradually become the key work for the foundational and clinical research in schizophrenia. Ultra-high risk for psychosis (UHP) is defined as individuals at the prodromal stage of schizophrenia. Early intervention in individual at UHP can effectively delay or even prevent the development of the illness. Long-term longitudinal studies suggested that there are clinical outcomes in people at UHP. Nearly 1/3 of individuals at UHP may be naturally relieved without any intervention, about 1/3 of individuals at UHP will remain at the prodromal stage of schizophrenia, and only 1/3 individuals at UHP will eventually develop schizophrenia. In this regard, it will cause adverse effects on false positive individuals if they accept clinical intervention. Unfortunately, it is difficult to accurately predict which individuals at UHP will make a transition to frank illness. To solve this issue, we explore the association between baseline brain structural and functional networks, methylation modifications, gene expression, neurocognitive function and the clinical outcomes of UHP individuals, and to identify the potential biological and clinical predictors for the long-term outcomes in the individuals at UHP. In addition, we also detect the changes of brain structure and function, methylation status and gene expression in individuals at UHP during follow-up, and further to investigate the etiology and pathogenesis of schizophrenia.
