About

This will be a pilot, single center, randomized, controlled trial to slow cognitive decline in adults undergoing hemodialysis (HD). The investigators will test two interventions (cognitive training and exercise training) against the standard of care.

Full description

This will be a pilot, single center, randomized, controlled trial to slow cognitive decline in adults undergoing hemodialysis (HD). The investigators primary objective is to demonstrate feasibility for the interventions (cognitive training and exercise training) in Aim 1. The investigators will formally test whether whether cognitive training (tablet-based brain games) and exercise training (stationary foot pedal) administered during HD slow cognitive decline as well as improve secondary outcomes (physical function, frailty, and health-related quality of life (HRQOL) as part of Aim 2. The investigators will compare these two interventions against the standard of care. Pre- and post-intervention assessments will be conducted at the dialysis unit by a study coordinator and by research assistants. Participants will be followed for 6 months to assess cognitive decline.

24 participants in 3 patient groups

Standard of care
No Intervention group
Description:
Participants randomized to the standard of care arm will not receive any intervention.
Cognitive training (CT)
Experimental group
Description:
Participants randomized to the CT arm will be given a tablet with connection to Lumosity®, which is a web-based "brain game". Participants will use the tablets to play brain games at each dialysis session.
Treatment:
Other: cognitive training
Exercise training (ET)
Active Comparator group
Description:
Participants randomized to ET arm will be given a stationary foot peddler. This foot peddler will be situated at a comfortable distance from the dialysis chair so that the patient can comfortably reach the peddler. Participants will use the foot peddlers at each dialysis session.
Treatment:
Other: exercise training
