5200 IMPACT OF MINERAL BONE PARAMETERS IN COGNITIVE IMPAIRMENT IN DIALYSIS PATIENTS

Abstract Background and Aims Mineral bone disease and cognitive impairment are related diseases in the CKD population. Vascular calcification, a marker of MBD, may play a role in the early detection of cognitive decline. This study aims to identify a relationship between MBD biomarkers and cognitive function and to identify dialysis patients with a high risk of dementia. Method A total of 98 patients participated in this cross-sectional study, with 63 on hemodialysis and 35 on peritoneal dialysis. They underwent the Montreal Cognitive Assessment (MoCA) questionnaire, which categorized mild, moderate, severe, and severe based on scoring. PTH, P, Ca, ALP, and Mg serum concentrations and vascular calcification were measured as MBD biomarkers. The Adragaos score was applied to graphs of the hands and pelvis to evaluate vascular calcification. Results The mean MoCA score was 20,28±5.8. Based on the responses, it was concluded that 70% of HD patients had mild cognitive impairment, compared to 63% of PD patients. According to the descriptive data, patients whose underlying CKD was caused by nephroangisclerosis had the lowest MOCA test results compared to other groups (p
