Twenty eight patients with Parkinson's disease (average age 63 years, average duration of disease 8 years) and 28 normal elderly controls (average age 70 years) were tested for their ability to appreciate the prosodic aspects of their own and others' speech and facial expression. Compared with the controls the Parkinsonian subjects performed worse at these tests, though both groups could easily identify neutral statements. The Parkinsonian subjects were unable to produce statements in an angry or questioning form. These seemed to be features of early Parkinson's disease.
对28名帕金森病患者（平均年龄63岁，平均病程8年）和28名正常老年对照者（平均年龄70岁）进行了测试，以评估他们理解自身及他人言语和面部表情韵律方面的能力。与对照组相比，帕金森病受试者在这些测试中的表现较差，不过两组都能轻松识别中性陈述。帕金森病受试者无法以愤怒或疑问的形式表达陈述。这些似乎是早期帕金森病的特征。
