Comparison of Dialysis Therapies on Cognitive Function

April 16, 2019 updated by: Satellite Healthcare
This study will evaluate the effects of more frequent dialysis on cognitive function including the assessment of sleep apnea and restless legs. Our hypothesis is that more frequent dialysis improves cognitive function and may have important implications on clinical care of ESRD patients and help to emphasize the need for treatments that will allow patients to live "with dialysis" rather than live "for dialysis".

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
1
Prevalent patients who have been receiving more frequent dialysis.
Trailmaking A, Trailmaking B, Rey Auditory Verbal Learning, Letter Number Sequencing, Digit Symbol Substitution, Grooved Pegboard, Controlled Oral Word Association, Beck Depression Index, Feeling Thermometer, Modified Mini-Mental Status

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Time Frame
Distribution of cognitive function impairment in ESRD patients undergoing more frequent hemodialysis
Time Frame: baseline, 4 months and 12 months

To test the hypothesis that nightly or daily hemodialysis treatment can ultimately be proven to be cost effective options by preserving cognitive function.
Time Frame: 12 months
12 months
Influence of cognitive function on survival.
