Cognitive impairment is common in Chronic Kidney Disease (CKD). Severely reduced kidney function (eGFR) and albuminuria are linked to cognitive decline, suggesting potential dementia prevention strategies.
Area of Science:
- Nephrology
- Neurology
- Geriatrics
Background:
- Cognitive impairment and Chronic Kidney Disease (CKD) are prevalent in aging populations.
- Increasing lifespans are expected to exacerbate the prevalence of both conditions.
- The underlying mechanisms linking CKD to cognitive impairment remain largely unknown.
Purpose of the Study:
- To review the prevalence of cognitive impairment in CKD patients.
- To explore potential mechanisms contributing to cognitive impairment in CKD.
- To examine the association between cognitive impairment and key CKD markers like eGFR and albuminuria.
Main Methods:
- Literature review of studies investigating cognitive function in CKD.
- Analysis of data correlating estimated glomerular filtration rate (eGFR) with cognitive status.
- Evaluation of the impact of albuminuria, dialysis, and kidney transplantation on cognitive function.
Main Results:
- Mild-moderate reductions in eGFR may not significantly impact cognition, but severely decreased eGFR is associated with impairment.
- Patients undergoing dialysis exhibit a high prevalence of cognitive impairment.
- Cognitive function generally improves post-kidney transplantation, though residual deficits persist.
Conclusions:
- Severely reduced eGFR and the presence of albuminuria are linked to cognitive impairment in CKD.
- Albuminuria, often undiagnosed, presents a potential target for dementia prevention strategies.
- Anemia and metabolic disturbances common in CKD may also contribute to cognitive deficits.
