The purpose of the study was to examine the hypothesis that patients with Parkinson's disease have a general inability to cope with concurrent task demands, and that this inability stems from a lack of attentional control of motor and cognitive activities. Performance on a verbal and on a visuospatial memory task was compared with performance on largely identical memory tasks which were combined with concurrent non-motor tasks. As a further index of a possible weakness of the attentional control of cognitive function order memory was assessed and compared with item memory. Both parkinsonian patients and controls showed a decline of memory performance when the concurrent task was introduced, but the degree of decline did not differ between groups. Parkinsonian patients scored worse than controls on both conditions of the verbal memory task and had more intrusions from previous lists in the verbal single task. There was no significant difference between groups in either item or order memory, but in parkinsonians the scores on order memory decreased with advancing illness. It is concluded that patients with Parkinson's disease do not have a general inability to cope with concurrent task demands, but that the results can be interpreted as indicating a weakness of certain aspects of the attentional control of cognitive function.
帕金森病患者普遍无法应对并发任务需求,且这种无能源于对运动和认知活动缺乏注意力控制。将言语和视觉空间记忆任务的表现与在很大程度上相同但与并发非运动任务相结合的记忆任务的表现进行比较。作为认知功能注意力控制可能存在弱点的进一步指标,对顺序记忆进行评估并与项目记忆进行比较。引入并发任务时,帕金森病患者和对照组的记忆表现均有所下降,但两组下降程度无差异。在言语记忆任务的两种情况下,帕金森病患者的得分均低于对照组,且在言语单一任务中,来自先前列表的干扰更多。在项目记忆或顺序记忆方面,两组之间无显著差异,但在帕金森病患者中,顺序记忆得分随病情进展而下降。得出的结论是,帕金森病患者并非普遍无法应对并发任务需求,但结果可解释为表明认知功能注意力控制的某些方面存在弱点。
