Hemodialysis-based Interventions to Preserve Cognitive Function

Not Applicable
Terminated
Conditions
Kidney Failure, Chronic
Interventions
Other: cognitive training
Other: exercise training
Registration Number
NCT02697942
Lead Sponsor
Johns Hopkins Bloomberg School of Public Health
Brief Summary

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.

Detailed 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.

Arm && Interventions
GroupInterventionDescription
Cognitive training (CT)cognitive trainingParticipants 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.
Exercise training (ET)exercise trainingParticipants 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.
Primary Outcome Measures
NameTimeMethod
Cognitive function measured using the Modified Mini Mental Status6 months post-intervention

Cognitive decline assessed as both the change in Modified Mini Mental Status and Trail making Test A and B scores as well as 10% decline in these measures of cognitive function

Secondary Outcome Measures
NameTimeMethod
health-related quality of life (HRQOL)6 months post-intervention

measured by the Kidney Disease Quality of Life Scale

Cognitive function6 months post-intervention

measured using the Trails Making Test A and B

physical function measured using the Short Physical Performance Battery (SPBB)6 months post-intervention

SPBB score of \<10 considered as physical function impaired

Fried frailty phenotype6 months post-intervention

Defined by the presence of 3 or more of the following: slowed walking speed, low physical activity, exhaustion, poor grip strength, and low physical activity. This is a binary outcome
