Patients with schizophrenia have difficulties processing the emotional and cognitive states of others. Neuroimaging studies show inconsistent findings.
We used a Seed-based d Mapping meta-analytic method to explore brain activation during facial emotion recognition and theory of mind tasks in schizophrenia patients.
The patients showed lesser recruitment of the facial emotion processing network; behavioural performance was associated with the activation of the precentral gyrus. We found abnormal activation of the mentalising network in schizophrenia patients during reasoning about other people's mental states; patients with worse performances showed lesser activation in the right insula and superior temporal gyrus. Multimodal meta-analysis showed overlaps of brain-related abnormalities for both modalities in schizophrenia, with reduced recruitment of the right insula, anterior cingulate and medial prefrontal cortex and increased activation in the bilateral parietal cortex. Meta-regression results indicate that illness duration, medication and symptomatology might influence social-cognitive network disruptions in schizophrenia.
These findings suggest the complex impairment of social cognition, as demonstrated by neural-related circuit disruptions during facial emotion processing and theory of mind tasks in schizophrenia.
精神分裂症患者在处理他人的情感和认知状态方面存在困难。神经影像学研究得出的结果并不一致。
我们使用基于种子的弥散张量成像(d Mapping)元分析方法,探讨精神分裂症患者在进行面部情绪识别和心理理论任务时的大脑激活情况。
患者的面部情绪处理网络的激活程度较低;行为表现与中央前回的激活有关。我们发现精神分裂症患者在推理他人心理状态时,心理理论网络的激活异常;表现较差的患者右侧脑岛和颞上回的激活程度较低。多模态元分析显示,精神分裂症两种模态的大脑相关异常存在重叠,右侧脑岛、前扣带回和内侧前额叶皮质的激活减少,双侧顶叶皮质的激活增加。元回归结果表明,疾病持续时间、药物和症状可能会影响精神分裂症的社会认知网络紊乱。
这些发现表明,精神分裂症患者在进行面部情绪处理和心理理论任务时,神经相关回路存在紊乱,表明其社会认知存在复杂的损伤。
