UNLABELLED: <p>Introduction: Patients with end-stage kidney disease develop cognitive impairment due to comorbidities and dialysis dependence. Among community-dwelling older adults, cognitive (CT) and exercise training (ET) are promising interventions to preserve cognition; these interventions may be tailored for adults undergoing in-center hemodialysis.
METHODS: Adult (≥18 years) English-speaking patients undergoing hemodialysis (within 3 months to 3 years of initiation) were enrolled in a 2 × 2 factorial randomized controlled trial: Interventions Made to Preserve Cognitive Function Trial (IMPCT). Participants (n = 121) were block-randomized (September, 2018-February, 2023) into 4 arms: control (SC) (n = 26), intradialytic web-based CT (n = 31), ET using foot peddler (n = 29), and combined CT+ET (n = 35). Participants underwent assessments at baseline and 3 months for executive function, global cognitive function, clinical outcomes, and patient-centered outcomes. We estimated 3-month executive function change (primary outcome) and secondary outcomes using linear regression.
RESULTS: There were no differences in 3-month executive function change by arm. Participants exhibited improvement in 3-month global cognitive function in CT+ET arm (Montreal Cognitive Assessment score difference = 2.1, 95% CI: 0.4-3.9), and self-reported 3-month improvement in perceived health change (score difference = 0.8, 95% CI: 0.2-1.4) in ET arm.
CONCLUSION: Clinicians may encourage CT+ET for hemodialysis patients to improve short-term global cognitive function and perceived health. The long-term benefits of these interventions warrant further study. </p>.
