Parkinson's disease is characterised by the presence of motor symptoms including hypomimia, and by non-motor symptoms including alterations in facial recognition of basic emotions. Few studies have investigated this alteration and its relationship to the severity of hypomimia.
The objective is to study the relationship between hypomimia and the facial recognition of basic emotions in subjects with Parkinson's disease.
Twenty-three patients and 29 controls were evaluated with the test battery for basic emotion facial recognition. The patients were divided into two subgroups according to the intensity of their hypomimia.
The comparison in battery test performance between the minimal/mild hypomimia and moderate/severe hypomimia groups was statistically significant in favour of the former group.
This finding shows a close relationship between expression and facial recognition of emotions, which could be explained through the mechanism of motor simulation.
帕金森病的特征是存在包括表情减少在内的运动症状，以及包括基本情绪面部识别改变在内的非运动症状。很少有研究调查这种改变及其与表情减少严重程度的关系。
研究帕金森病患者表情减少与基本情绪面部识别之间的关系。
对23例患者和29名对照者进行基本情绪面部识别测试组评估。根据表情减少的程度将患者分为两个亚组。
最小/轻度表情减少组与中度/重度表情减少组在测试组表现上的比较具有统计学意义，前者更具优势。
这一发现表明情绪表达与面部识别之间存在密切关系，这可以通过运动模拟机制来解释。
