Exploring the potential relationship between kidney disease index and cognitive dysfunction: a machine learning approach with NHANES data

KDI may be a reliable and effective indicator for predicting cognitive function and the risk of cognitive impairment in the elderly. Research suggests that higher KDI levels may serve as a risk factor for cognitive decline, underscoring the importance of managing KDI for cognitive health, particularly in populations with chronic kidney disease (CKD). Future studies should focus on longitudinal research and clinical interventions to further validate the clinical utility of KDI and develop treatment strategies based on KDI.
