The ability to recognize emotions from facial expression (FER) may be impaired in Parkinson's disease (PD). We aimed to explore FER in PD patients by using a dynamic presentation of emotions across different intensities and to examine the extent to which executive and affective alterations contributed to FER deficits.
Fifteen PD patients and 15 healthy controls were assessed on the emotion recognition task (ERT). We also explored how clinical and executive factors could have contributed to ERT accuracy.
PD patients showed poorer performance on the ERT, specifically on angry expressions, but they benefited from increased intensity as much as controls did. Differences were also found for apathy, depression, and executive tests, especially in the inhibition domain. Importantly, differences between groups on the ERT disappeared when controlling for inhibition and the affective symptoms. A significant effect of inhibition dysfunction was also observed on the ERT performance.
Our findings demonstrate the presence of emotion recognition deficits of morphed facial expressions in patients with PD. Moreover, they suggest that inhibition dysfunctions may act as an important factor negatively influencing FER. The present study highlights the complex nature of emotion processing and its relation with emotional-affective and cognitive aspects to provide a better understanding of FER deficits in PD.

识别面部表情（FER）所表达的情绪的能力可能在帕金森病（PD）患者中受损。我们旨在通过使用不同强度的情绪动态呈现来探索 PD 患者的 FER，并研究执行和情感改变在多大程度上导致 FER 缺陷。
15 名 PD 患者和 15 名健康对照者接受了情绪识别任务（ERT）评估。我们还探讨了临床和执行因素如何有助于 ERT 准确性。
PD 患者在 ERT 上表现较差，特别是在识别愤怒表情方面，但他们像对照组一样受益于表情强度的增加。在冷漠、抑郁和执行测试方面也存在差异，尤其是在抑制领域。重要的是，当控制抑制和情感症状时，组间在 ERT 上的差异消失。抑制功能障碍对 ERT 表现也有显著影响。
我们的研究结果表明，PD 患者存在变形面部表情的情绪识别缺陷。此外，它们表明抑制功能障碍可能是一个重要因素，对 FER 产生负面影响。本研究强调了情绪处理的复杂性及其与情感-情感和认知方面的关系，以更好地理解 PD 中的 FER 缺陷。
