  Purpose
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".

Condition Intervention
End Stage Renal Disease Chronic Kidney Disease Other: Cognitive Function Testing-10 Tests Other: Sleep Assessment Testing Other: Periodic Leg Movement Syndrome Assessment

Further study details as provided by Satellite Healthcare:

Primary Outcome Measures:
  • Distribution of cognitive function impairment in ESRD patients undergoing more frequent hemodialysis [ Time Frame: baseline, 4 months and 12 months ]

Secondary Outcome Measures:
  • Longitudinal analysis of cognitive function over time to test the hypothesis that more frequent hemodialysis contributes to delay in cognitive function impairment [ 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 ]
  • Influence of cognitive function on survival. [ Time Frame: 12 months ]

Estimated Enrollment: 100
Study Start Date: December 2007
Estimated Study Completion Date: December 2011
Estimated Primary Completion Date: December 2011 (Final data collection date for primary outcome measure)
