Association of Cardiovascular-Kidney-Metabolic Syndrome With Cognitive Decline and Dementia: The ARIC Study Insights

Area of Science:

• Cardiovascular health
• Nephrology
• Metabolic disorders
• Neurology
• Gerontology

Background:

• Cardiovascular-kidney-metabolic (CKM) syndrome represents a complex interplay of interrelated conditions.
• A holistic approach is increasingly recognized as essential for managing CKM syndrome.
• The impact of CKM syndrome on cognitive function, including dementia, is not well understood.

Purpose of the Study:

• To investigate the association between CKM syndrome risk categories and the incidence of cognitive decline.
• To examine the relationship between CKM risk levels and dementia development.
• To determine if higher CKM risk is linked to accelerated cognitive decline or dementia progression.

Main Methods:

• Utilized data from 10,426 participants in the Atherosclerosis Risk in Communities (ARIC) study.
• Classified participants into four CKM risk categories: low, borderline, intermediate, and high.
• Employed regression analysis to assess the association between CKM risk and cognitive outcomes.

Main Results:

• A significant association was found between elevated CKM risk levels and increased risks of cognitive decline and dementia.
• Each one-unit increase in CKM risk score correlated with a 6% higher risk of dementia progression.
• The findings remained significant after adjusting for potential confounding factors.

Conclusions:

• There is a strong link between CKM syndrome and cognitive decline or incident dementia.
• Early identification and management of CKM risk factors may be vital for preserving cognitive health.
• Further research is warranted to explore CKM syndrome's specific mechanisms impacting the brain.
