A growing body of evidence suggests Chronic Lower Back Pain (CLBP) is associated with cognitive dysfunction. Little is known, however, about the extent of cognitive impairment in CLBP. The present study explored the cognitive profile of people with CLBP and sought to determine the extent of Mild Cognitive Impairment (MCI) according to the DSM-V and the Movement Disorders Society criteria for MCI. Thirty-one participants with CLBP and 27 age and gender matched healthy controls completed a full neuropsychological battery, consisting of two tasks for each of the five cognitive domains (Executive Function, Attention/Working Memory, Memory, Language, and Visuospatial). Participants with CLBP performed worse, compared to controls, on measures of Attention/Working Memory, Memory, Language, and Visuospatial performance. Cognitive performance in CLBP was also compared to equivalent normative data to determine cognitive impairment. Sixteen CLBP participants were impaired on at least one cognitive measure, with 5 participants meeting criteria for MCI. MCI was not associated with pain-related experience, or psychological health. The present study supports and extends previous findings that CLBP is associated with cognitive dysfunction and some people with CLBP meet criteria for MCI. These findings support that rehabilitation in people with CLBP requires a multidisciplinary approach.

越来越多的证据表明，慢性下腰痛（CLBP）与认知功能障碍有关。然而，关于CLBP认知障碍的程度知之甚少。本研究探讨了患有CLBP的人的认知状况，并试图根据DSM-V和运动障碍协会针对MCI的标准确定轻度认知障碍（MCI）的程度。31名具有CLBP和27位年龄和性别相匹配的健康对照组的参与者完成了完整的神经心理学研究，其中包括针对五个认知领域（执行功能，注意力/工作记忆，记忆，语言和视觉空间）中的每一项的两项任务。与对照组相比，CLBP的参与者在注意/工作记忆，记忆，语言和视觉空间表现方面的表现较差。还将CLBP的认知表现与同等的规范数据进行比较，以确定认知障碍。16名CLBP参与者在至少一项认知指标上受损，其中5名参与者符合MCI标准。MCI与疼痛相关的经历或心理健康无关。本研究支持并扩展了先前的发现，即CLBP与认知功能障碍相关，并且某些CLBP符合MCI标准。这些发现支持CLBP患者的康复需要多学科的方法。本研究支持并扩展了先前的发现，即CLBP与认知功能障碍相关，并且某些CLBP符合MCI标准。这些发现支持CLBP患者的康复需要多学科的方法。本研究支持并扩展了先前的发现，即CLBP与认知功能障碍相关，并且某些CLBP符合MCI标准。这些发现支持CLBP患者的康复需要多学科的方法。
