Factors Affecting Neurocognitive Function in Children with Chronic Kidney Disease: A Systematic Review

In children, chronic kidney disease (CKD) has been known to affect neurocognitive function which can impair the quality of life. This study aims to determine the factors and treatment modalities which might affect neurocognitive function in pediatric population with CKD.

A systematic review was done using 3 electronic databases: PubMed, ScienceDirect, SpringerLink, and carried out based on PRISMA guidelines. Our review included articles published in the last 10 years (2011-2021) in English, on children aged 0-18 years with CKD. Factors affecting the children's neurocognitive function were assessed.

Eight articles were included in this study. Three articles reported that parent's education, especially maternal education affect the neurocognitive function of children with CKD. In relation with modalities, in general, children with CKD who had kidney transplant had a better neurocognitive outcome. A longer duration of hemodialysis (HD) was associated with poorer neurocognitive outcomes. Other factors that can affect the neurocognitive function included depression, a history of abnormal births, seizures, and hypertension.

In children, CKD might cause neurocognitive function disorders through various complex and interconnected mechanisms. Further studies are needed to determine the mechanism and prevention of neurocognitive disorders, as well as the best choice of therapeutic modality to improve both kidney function and neurocognitive function in children with CKD.
