通过31项自评问卷调查帕金森病（PD）的视觉/视觉空间和运动症状的相互作用。81名非痴呆患者中的大多数报告了依赖于视觉或视觉空间能力的非运动任务的问题。超过三分之一的人报告了幻视、复视和难以估计空间关系。步态冻结与幻视、复视和对比敏感度缺陷有关。视觉策略经常被用来克服冻结。结果强调了研究PD中视觉和视觉空间障碍及其与运动症状的关系的重要性，以帮助患者制定成功的补偿策略。(c)2004 Elsevier Ltd.保留所有权利。
The interaction of visual/visuospatial and motor symptoms in Parkinson's disease (PD) was investigated by means of a 31-item self-report questionnaire. The majority of 81 non-demented patients reported problems on non-motor tasks that depended on visual or visuospatial abilities. Over a third reported visual hallucinations, double vision and difficulty estimating spatial relations. Freezing of gait was associated with visual hallucinations, double vision and contrast sensitivity deficits. Visual strategies frequently were employed to overcome freezing. The results underscore the importance of investigating visual and visuospatial impairments in PD and their relation to motor symptoms, in order to help patients develop successful compensatory strategies.
