Perceived Cognitive Function in People with Systemic Sclerosis: Associations with Symptoms and Daily Life Functioning

Résumé

OBJECTIVES: Perceived cognitive dysfunction is prevalent in patients with systemic sclerosis (SSc) but not well-understood. This study aimed to examine potential factors associated with perceived cognitive function and to investigate the contributions of perceived cognitive function and symptoms to functional measures. METHODS: A cross-sectional survey was conducted among patients with SSc (N = 106). Participants were mainly female (84%) and White (82%). Perceived cognitive function, symptoms, and functional measures were assessed with PROMIS measures. A multivariable regression was conducted to identify factors associated with perceived cognition. Hierarchical linear regressions examined the unique contributions of perceived cognitive function and symptoms to social participation and physical function. RESULTS: Fifty-nine (56%) patients with SSc perceived mild to severe cognitive dysfunction. Being on work disability and having more fatigue were both significantly associated with perceived cognitive dysfunction. When examining the contributions of cognition and other symptoms to functional measures, self-reported cognition became nonsignificant after fatigue and pain were entered into the regression model. CONCLUSION: Being on work disability and having more fatigue were most highly associated with perceived cognitive dysfunction in patients with SSc. Unlike fatigue and pain, perceived cognitive function was not independently associated with functional measures. Nonetheless, future research should disentangle cognitive function and other symptoms as well as their effects on daily activities in SSc. This article is protected by copyright. All rights reserved.
