Improved Heart Health Linked to Slower Brain Aging and Reduced Dementia Risk

March 17, 2025 - 14:02

A recent study published in JAMA Network Open highlights the connection between cardiovascular health and brain aging in older adults. The research reveals that maintaining better cardiovascular health (CVH) is associated with lower levels of neurodegenerative biomarkers, specifically neurofilament light chain (NfL), which is a key indicator of neurodegeneration.

The findings suggest that individuals with optimal heart health experience significant benefits in brain function, regardless of their racial background. This is particularly noteworthy for those who carry genetic risks associated with Alzheimer's disease. The study underscores the importance of cardiovascular wellness not only for heart health but also for cognitive longevity.

As the population ages, understanding the interplay between heart health and brain function becomes increasingly vital. This research provides valuable insights that could inform preventive strategies aimed at reducing the risk of dementia and promoting healthier aging. Emphasizing cardiovascular health may be a promising avenue for enhancing overall cognitive resilience in older adults.
