Chronic kidney disease (CKD) is linked to cognitive impairment (CI) in older adults. Managing CKD risk factors and cognitive health is crucial for better patient outcomes.
Area of Science:
- Nephrology
- Neurology
- Geriatrics
Background:
- Chronic kidney disease (CKD) affects 25% of individuals over 70.
- Cognitive impairment (CI) is prevalent in 30-60% of hemodialysis patients.
- CKD-CI link involves shared risk factors (hypertension, diabetes) and CKD-specific mechanisms (vascular, degenerative, toxic).
Purpose of the Study:
- To review the relationship between CKD and CI.
- To identify risk factors and affected cognitive domains in CKD patients.
- To discuss preventive strategies and management considerations for CI in CKD.
Main Methods:
- Literature review focusing on CKD and cognitive impairment.
- Analysis of risk factors, including albuminuria and glomerular filtration rate.
- Examination of cerebrovascular and neurodegenerative pathways linking CKD and CI.
Main Results:
- Albuminuria is a stronger predictor of CI than GFR in non-dialyzed CKD.
- Vascular dementia is the primary cause of CI in CKD; Alzheimer's disease incidence is also elevated in end-stage kidney disease.
- Executive functions, orientation, and attention are the most affected cognitive domains.
Conclusions:
- Controlling blood pressure and using anticoagulants for atrial fibrillation may prevent CI in CKD patients.
- Nephrological care can influence neurological complications; caution is advised with certain medications in CKD.
- Cognitive assessment is recommended for severe CKD patients to guide renal replacement therapy decisions.
