This is a randomized, controlled trial to slow cognitive decline in adults undergoing hemodialysis (HD). The investigators will test three interventions cognitive training (CT), exercise training (ET), and combined cognitive and exercise training (CT+ET) relative to standard of care (SC).

Study summary:

This will be a two by two factorial, randomized, controlled trial to slow cognitive decline in adults undergoing hemodialysis (HD). The investigators primary objective is to determine if receiving cognitive training (tablet-based brain games), exercise training (stationary foot pedal), or combined cognitive and exercise training preserves executive function relative to those with standard of care . The secondary objectives are to compare the rates of end stage renal disease (ESRD)-specific clinical outcomes and patient centered outcomes among those receiving CT, or ET, or CT+ET relative to those in SC. The investigators will formally test whether receiving CT or ET will preserve executive function and receiving combined CT+ET will preserve executive function better than CT or ET alone.


Inclusion Criteria: - 18 years or older at enrollment - English speaking - within 3 months to 3 years of initiating hemodialysis - receiving hemodialysis at participating dialysis centers Exclusion Criteria: Patients with the following conditions will be excluded: - Pregnancy - Angina Pectoris - Chronic lung disease requiring oxygen - Musculoskeletal conditions that limit mobility - Upper or lower extremity amputation - Orthopedic disorders exacerbated by physical activity - Femoral arteriovenous (AV) access - Hepatitis B infection - Blindness/Legal blindness In addition to conditions outlined above, patients who are currently incarcerated will be excluded from the study.
