Previous research on visuospatial function in Parkinson's disease is reviewed. The present experiment was designed to test two fundamental aspects of spatial ability, namely right-left discrimination and the manipulation of those concepts in different spatial perspectives. Measures of accuracy and reaction time were taken. The performance of patients with Parkinson's disease did not differ from that of normal subjects in the spatial components of the task. Neither a review of the literature, nor the results of the present study, give support to the idea of a generalized visuospatial deficit in Parkinson's disease.
本文回顾了先前关于帕金森病视觉空间功能的研究。本实验旨在测试空间能力的两个基本方面，即左右辨别以及在不同空间视角下对这些概念的操作。记录了准确性和反应时间的测量结果。帕金森病患者在该任务的空间组成部分上的表现与正常受试者无异。无论是文献综述还是本研究的结果，均不支持帕金森病存在普遍视觉空间缺陷这一观点。
