Patients with Parkinson's disease have difficulty in performing two different tasks simultaneously. The present study tested whether this deficit was specific to the disease or was found in other patient groups. An identical pattern of performance was shown by a group of patients with cerebellar disease and, to a lesser extent, by a group of patients with Huntington's disease. Further research should focus on clarifying the nature of the deficits and the reasons for the similar performances in the various patient groups.
帕金森病患者在同时执行两项不同任务时存在困难。本研究测试了这种缺陷是该疾病所特有的，还是在其他患者群体中也存在。一组小脑疾病患者表现出了相同的表现模式，而一组亨廷顿舞蹈症患者在较小程度上也表现出了相同的表现模式。进一步的研究应集中于阐明这些缺陷的本质以及不同患者群体中表现相似的原因。
