摘要精神病临床高危综合征以弱化的精神病性症状和认知功能损伤为特征，随访时转化为精神分裂症的患者往往表现出更严重的认知功能损伤。近年来，任务态功能磁共振成像研究为揭示不同认知功能损伤的神经生物学基础提供了客观特征，为预测精神病高转化风险的人群提供了生物学标志，并为发展早期干预提供了潜在靶点。本文对精神病临床高危综合征认知功能损伤的功能磁共振成像研究进展进行综述，包括认知功能相关的脑区活动异常特征、与临床症状的关联等，并对利用功能磁共振成像特征预测转化风险进行展望。

abstractsAttenuated psychotic symptoms and cognitive impairments characterize individuals at clinical high risk (CHR) for psychosis. Those who convert to schizophrenia during the follow-up often exhibit more severe cognitive impairments. Recently, task functional magnetic resonance imaging(fMRI) studies have provided imaging features for revealing the neurobiological basis of different cognitive function impairments, biomarkers for predicting conversion to psychosis, and potential targets for developing the early intervention. This review summarized the progress of fMRI studies focused on cognitive impairments, including the features of abnormal brain activities related to cognitive functions and clinical symptoms. The authors also looked at the possibility of predicting clinical conversion based on the fMRI features.
