Patients with end-stage renal disease on continuous ambulatory peritoneal dialysis (CAPD) showed better cognitive function than those on hemodialysis. This suggests dialysis modality may impact neurological health in kidney failure patients.

Area of Science:

  • Nephrology
  • Neuroscience
  • Clinical Medicine

Background:

  • End-stage renal disease (ESRD) is associated with neurological complications, including impaired cognitive function.
  • Cognitive deficits may differ based on the type of renal replacement therapy used.

Purpose of the Study:

  • To compare mental performance between patients undergoing hemodialysis (HD) and continuous ambulatory peritoneal dialysis (CAPD).
  • To assess cognitive function using the Trail Test A in ESRD patients and healthy controls.

Main Methods:

  • A cohort of patients on HD and CAPD, along with age- and sex-matched healthy controls, were administered the Trail Test A.
  • Completion time for Trail Test A served as the primary measure of cognitive performance.

Main Results:

  • Healthy controls completed the test in 30.7 ± 2.4 seconds.
  • CAPD patients averaged 47.2 ± 6.4 seconds, significantly faster than hemodialysis patients (82.6 ± 11 seconds).
  • Patients on CAPD demonstrated significantly better cognitive performance compared to those on hemodialysis (p < 0.05).

Conclusions:

  • Continuous ambulatory peritoneal dialysis is associated with superior cognitive function compared to hemodialysis in end-stage renal disease patients.
  • The observed differences in mental performance may be multifactorial and warrant further investigation.
  • Findings may inform clinical decisions for patients and clinicians considering dialysis modality options.
