ObjectivesChronic pain, cognitive deficits, and pain-related disability are interrelated. The prevalence of chronic pain and undiagnosed cognitive difficulties in middle age and older adults is increasing. Of the cognitive systems, executive function and episodic memory are most relevant to chronic pain. We examined the hypothesis that cognitive screening composite scores for executive function and memory would negatively associate with pain intensity and pain disability in a group of middle-aged and older adults with knee pain with or at risk for osteoarthritis.MethodsA total of 120 adults (44 men/76 women), an average age of 59 years, participated in the study. Demographic, health history, clinical pain, and cognitive measures were completed. Relationships between pain intensity, pain disability, and the Montreal Cognitive Assessment (MoCA) total and composite scores were examined with relevant covariates in the model.ResultsMoCA raw scores ranged from 13 to 30 with a mean score of 23.9. Pain intensity was negatively associated with overall MoCA total and executive function and memory composite scores. Pain disability over the previous 6 months was negatively associated with executive function, while pain disability over the past 48 hours was not associated with executive function.ConclusionThe results of the current study demonstrates associations between pain metrics and cognitive domain scores within a common cognitive screening tool.Copyright © 2022 Wolters Kluwer Health, Inc.
