Abstract

Understanding facial emotions is fundamental to interact in social environments and modify behavior accordingly. Neurodegenerative processes can progressively transform affective responses and affect social competence. This exploratory study examined the neurocognitive correlates of face recognition, in individuals with two mild cognitive impairment (MCI) etiologies (prodromal to dementia - MCI, or consequent to Parkinson's disease - PD-MCI). Performance on the identification and memorization of neutral and emotional facial expressions was assessed in 31 individuals with MCI, 26 with PD-MCI, and 30 healthy controls (HC). Individuals with MCI exhibited selective impairment in recognizing faces expressing fear, along with difficulties in remembering both neutral and emotional faces. Conversely, individuals with PD-MCI showed no differences compared with the HC in either emotion recognition or memory. In MCI, no significant association emerged between the memory for facial expressions and cognitive difficulties. In PD-MCI, regression analyses showed significant associations with higher-level cognitive functions in the emotional memory task, suggesting the presence of compensatory mechanisms. In a subset of participants, voxel-based morphometry revealed that the performance on emotional tasks correlated with regional changes in gray matter volume. The performance in the matching of negative expressions was predicted by volumetric changes in brain areas engaged in face and emotional processing, in particular increased volume in thalamic nuclei and atrophy in the right parietal cortex. Future studies should leverage on neuroimaging data to determine whether differences in emotional recognition are mediated by pathology-specific atrophic patterns.

轻度认知障碍患者的面部情绪识别:一项探索性研究。
了解面部情绪是在社会环境中进行互动并相应改变行为的基础。神经退行性过程会逐渐改变情感反应并影响社交能力。这项探索性研究考察了两种轻度认知障碍(MCI)病因(痴呆前驱期--MCI,或帕金森病后遗症--PD-MCI)患者面部识别的神经认知相关性。我们对31名MCI患者、26名帕金森病-MCI患者和30名健康对照组(HC)进行了中性和情绪性面部表情的识别和记忆能力评估。MCI 患者在识别表示恐惧的面部表情方面表现出选择性障碍,同时在记忆中性和情绪面部表情方面也存在困难。相反,PD-MCI 患者与 HC 相比,在情绪识别或记忆方面均无差异。在 MCI 患者中,面部表情记忆与认知困难之间没有明显联系。在帕金森氏综合症-多发性硬化症患者中,回归分析表明情绪记忆任务与更高层次的认知功能有显著关联,这表明存在补偿机制。在一部分参与者中,基于体素的形态测量显示,情绪任务的表现与灰质体积的区域变化相关。参与面部和情绪处理的大脑区域的体积变化,尤其是丘脑核体积的增加和右顶叶皮层的萎缩,预测了负性表情匹配的表现。未来的研究应利用神经影像学数据来确定情绪识别方面的差异是否由病理学特异性萎缩模式介导。

期刊介绍: Cognitive, Affective, & Behavioral Neuroscience (CABN) offers theoretical, review, and primary research articles on behavior and brain processes in humans. Coverage includes normal function as well as patients with injuries or processes that influence brain function: neurological disorders, including both healthy and disordered aging; and psychiatric disorders such as schizophrenia and depression. CABN is the leading vehicle for strongly psychologically motivated studies of brain–behavior relationships, through the presentation of papers that integrate psychological theory and the conduct and interpretation of the neuroscientific data. The range of topics includes perception, attention, memory, language, problem solving, reasoning, and decision-making; emotional processes, motivation, reward prediction, and affective states; and individual differences in relevant domains, including personality. Cognitive, Affective, & Behavioral Neuroscience is a publication of the Psychonomic Society.
