Disentangling the multiple links between renal dysfunction and cerebrovascular disease

Area of Science:

• Nephrology and Neurology
• Epidemiology of Chronic Diseases
• Cardiovascular and Cerebrovascular Health

Background:

• Chronic kidney disease (CKD) prevalence is rising globally, particularly in older adults.
• CKD is a significant risk factor for cardiovascular disease, especially stroke.
• Associations exist between CKD and subclinical cerebrovascular abnormalities, cognitive impairment, and dementia.

Purpose of the Study:

• To review the current understanding of cerebrovascular disease epidemiology in CKD patients.
• To explore the pathophysiology linking CKD to cerebrovascular complications.
• To discuss the role of traditional and non-traditional risk factors in this association.

Main Methods:

• Review of cohort studies and clinical trials.
• Analysis of epidemiological data on CKD and stroke incidence.
• Examination of pathophysiological mechanisms and risk factors.

Main Results:

• Reduced glomerular filtration rate increases stroke risk by approximately 40%.
• Proteinuria elevates stroke risk by approximately 70%.
• CKD is linked to both traditional (hypertension, diabetes) and non-traditional (uremia, oxidative stress) risk factors.

Conclusions:

• CKD poses a substantial risk for cerebrovascular disease, including stroke and cognitive decline.
• Multiple traditional and non-traditional factors contribute to the CKD-cerebrovascular link.
• Understanding these mechanisms is crucial for managing stroke risk and treatment in CKD patients.
