Slowed processing speed is the primary cognitive deficit in multiple sclerosis (MS). However, no studies have examined how patients perceive this deficit. The purpose of this paper is to examine perceived processing speed difficulties in clinical and community samples of MS patients. As expected, MS patients reported more processing speed difficulties than controls. Perceived processing speed difficulties were significantly associated with impulsivity, slowed motor speed, greater anxiety, and increased introversion. In contrast, perceived processing speed did not correlate well with objective measures of processing speed. Findings showed that MS patients perceive their thinking to be significantly slowed. Perceived cognitive slowing was most related to performance on motor tasks and elevated anxiety. Evaluation of anxiety and patient education about objective measures versus subjective perceptions of slowed processing speed may be helpful to MS patients who report significant cognitive slowing.
处理速度缓慢是多发性硬化症（MS）的主要认知缺陷。然而，目前还没有研究调查患者如何感知这种缺陷。本文旨在研究 MS 患者的临床和社区样本中感知到的处理速度困难。正如预期的那样，MS 患者报告的处理速度困难比对照组更多。感知到的处理速度困难与冲动、运动速度减慢、更大的焦虑和更高的内向性显著相关。相比之下，感知到的处理速度与处理速度的客观测量没有很好的相关性。研究结果表明，MS 患者认为他们的思维明显减慢。感知到的认知减速与运动任务的表现和焦虑水平升高最为相关。对焦虑的评估以及对客观测量与感知到的处理速度减慢之间关系的患者教育，可能对报告存在显著认知减速的 MS 患者有所帮助。
