We investigated the role of perceptual and motor factors in visuospatial impairment in 30 patients with Parkinson's disease (PD) and 30 matched controls. All subjects were administered visuospatial tests, which included "visuoperceptual" tasks, requiring minimal motor responses, and "visuomotor" tasks. The performance of patients with PD was considerably impaired on several tasks from both groups, and this impairment was not related to depression or intellectual impairment. Patients in stage 3 of the disease tended to show the greatest impairment. Those in stage 1 (unilateral symptoms), however, tended to show more impairment than those in stage 2.
我们调查了30名帕金森病（PD）患者和30名匹配对照者中感知和运动因素在视觉空间障碍中的作用。所有受试者都接受了视觉空间测试，其中包括需要最少运动反应的“视觉感知”任务和“视觉运动”任务。PD患者在两组的多项任务中表现出明显受损，且这种损伤与抑郁或智力损伤无关。疾病3期的患者往往表现出最严重的损伤。然而，1期（单侧症状）的患者比2期的患者往往表现出更多的损伤。
