Impaired cognitive empathy (ie, understanding the emotional experiences of others) is associated with poor social functioning in schizophrenia. However, it is unclear whether the neural activity underlying cognitive empathy relates to social functioning. This study examined the neural activation supporting cognitive empathy performance and whether empathy-related activation during correctly performed trials was associated with self-reported cognitive empathy and measures of social functioning. Thirty schizophrenia outpatients and 24 controls completed a cognitive empathy paradigm during functional magnetic resonance imaging. Neural activity corresponding to correct judgments about the expected emotional expression in a social interaction was compared in schizophrenia subjects relative to control subjects. Participants also completed a self-report measure of empathy and 2 social functioning measures (social competence and social attainment). Schizophrenia subjects demonstrated significantly lower accuracy in task performance and were characterized by hypoactivation in empathy-related frontal, temporal, and parietal regions as well as hyperactivation in occipital regions compared with control subjects during accurate cognitive empathy trials. A cluster with peak activation in the supplementary motor area (SMA) extending to the anterior midcingulate cortex (aMCC) correlated with social competence and social attainment in schizophrenia subjects but not controls. These results suggest that neural correlates of cognitive empathy may be promising targets for interventions aiming to improve social functioning and that brain activation in the SMA/aMCC region could be used as a biomarker for monitoring treatment response.
认知共情受损(即理解他人的情感体验)与精神分裂症患者的社会功能不良有关。然而,认知共情背后的神经活动是否与社会功能相关尚不清楚。本研究考察了支持认知共情表现的神经激活,以及在正确执行试验期间与共情相关的激活是否与自我报告的认知共情和社会功能测量指标相关。30名精神分裂症门诊患者和24名对照者在功能磁共振成像期间完成了一项认知共情范式。比较了精神分裂症患者与对照者在社交互动中对预期情绪表达的正确判断所对应的神经活动。参与者还完成了一项共情的自我报告测量以及两项社会功能测量(社交能力和社会成就)。与对照者相比,在准确的认知共情试验期间,精神分裂症患者在任务表现上的准确性显著较低,其特点是与共情相关的额叶、颞叶和顶叶区域激活不足,以及枕叶区域激活过度。在辅助运动区(SMA)有峰值激活并延伸至前扣带回中部(aMCC)的一个簇与精神分裂症患者而非对照者的社交能力和社会成就相关。这些结果表明,认知共情的神经关联可能是旨在改善社会功能的干预措施的有希望的靶点,并且SMA/aMCC区域的脑激活可作为监测治疗反应的生物标志物。
