A survey of cognitive function in peritoneal dialysis patients.

Introduction: The aim of this study was to investigate how peritoneal dialysis and other influencing factors affect patients' cognitive function.

Methods: The 85 subjects in the study group were regular patients in our center. The control group included 88 age and gender matched healthy individuals who were with normal renal function. The study subjects' cognitive levels and related factors were analyzed using several screening instruments: the cognitive function was measured using the Montreal Cognitive Assessment Scale and statistical analysis was conducted based on the relevant data.

Results: The results showed that cognitive impairment was higher in peritoneal dialysis patients than in non-dialysis subjects. Age and educational background were single factors that affected cognitive function, which was more likely to be impaired at a higher age level and/or a lower educational level.

Conclusion: Cognitive function can be impaired by peritoneal dialysis, and age and education levels are influencing factors.
