多发性硬化症(MS)的认知症状包括处理速度缺陷和工作记忆障碍。这些缺陷在多发性硬化症患者中相互作用的确切方式仍有待阐明。我们假设在复杂的工作记忆任务上花更多的时间会使MS患者的表现优于健康对照组。53名临床明确的多发性硬化症患者和36名匹配的健康对照者进行了一项系统地操纵认知负荷的计算机化任务。刺激呈现之间的间隔被操纵以增加处理时间。结果证实,有处理速度缺陷的多发性硬化症患者在给予额外的时间来处理工作记忆中的信息时,表现的准确性显著提高。这些发现对开发适当的认知康复干预措施的意义进行了讨论。
Cognitive symptoms of multiple sclerosis (MS) include processing-speed deficits and working memory impairment. The precise manner in which these deficits interact in individuals with MS remains to be explicated. We hypothesized that providing more time on a complex working memory task would result in performance benefits for individuals with MS relative to healthy controls. Fifty-three individuals with clinically definite MS and 36 matched healthy controls performed a computerized task that systematically manipulated cognitive load. The interval between stimuli presentations was manipulated to provide increasing processing time. The results confirmed that individuals with MS who have processing-speed deficits significantly improve in performance accuracy when given additional time to process the information in working memory. Implications of these findings for developing appropriate cognitive rehabilitation interventions are discussed.
