    Cardiovascular disease is the leading cause of death worldwide, and nearly half of Americans are living with it.While heart attacks and strokes are among its most serious and life-threatening outcomes, they aren’t the only ways an unhealthy cardiovascular system affects the body. 

    Heart and brain health are deeply connected.  The same network of blood vessels that keeps the heart functioning also supplies the brain with oxygen and nutrients When those vessels become unhealthy, their dysfunction can affect memory, cognitive function, and long-term brain health. 

    February is American Heart Month, an important reminder that caring for your heart is a critical part of healthy aging In this article, we’ll explore how cardiovascular health shapes cognitive function, the shared risk factors linking heart disease and cognitive decline, and practical lifestyle and nutritional strategies that support both systems in the long term. 

     

    How Cardiovascular Disease Impacts Cognitive Decline 

    Cognitive decline doesn’t happen suddenly For many people, it develops gradually, with one significant shaping factor being vascular changes that impact how well the brain is nourished, protected, and able to function.  

     

    Why Healthy Blood Flow Is Essential for Brain Function 

    The brain uses 15-20% of the body’s total blood supply, relying on healthy blood vessels and a constant flow of nutrient-rich blood to carry out basic functions.2   

    When vascular health is compromised by stiffened arteries, narrowed vessels, or small-vessel disease, the brain may not receive what it needs.3  Over time, reduced blood flow can contribute to cumulative brain injury and result in structural changes, such as white matter damage and brain atrophy — both of which are linked to declines in cognitive performance.3  

    Recent research also shows that vascular dysfunction may accelerate age-related brain changes, even in individuals without a history of stroke or neurological disease.4  This suggests that even before cognitive symptoms become apparent, vascular health plays a role in brain aging. 

     

    Cardiovascular Disease as a Risk Factor for Dementia 

    Cardiovascular disease is consistently linked to cognitive decline and dementia In fact, individuals with a history of heart disease have a 27% higher risk of developing dementia than those without.5  

    Additionally, those who experience heart disease earlier in adulthood can carry an even greater long-term cognitive risk, most likely because vascular damage accumulates over decades.4,6  Further studies have supported this connection, linking cardiovascular disease with Alzheimer’s and vascular dementia.7  This stresses the importance of maintaining heart health — for the sake of your heart and your brain.  

     

    Vascular Dementia: Where Heart and Brain Intersect 

    Vascular dementia offers one of the clearest examples of the heart-brain connection.  In contrast to primarily neurodegenerative forms of dementia, vascular dementia results from impaired blood flow to the brain.  This is often caused by strokes, small vessel disease, or chronic vascular injury, including heart conditions like coronary artery disease (also called coronary heart disease), that limits oxygen and nutrient distribution to brain tissue, giving rise to cognitive decline.4  

     

    How Cardiovascular Risk Changes for Women and Why It Matters for Brain Health  

    Cardiovascular and cognitive risks can shift across a woman’s life, particularly after menopause Declining estrogen levels are associated with changes in vascular function, lipid metabolism, and blood pressure, which may increase cardiovascular risk during midlife and beyond.8  Women also experience higher rates of dementia overall, affected by a combination of longevity, hormonal causes, and vascular health.9  This further highlights why maintaining a healthy cardiovascular system is significant for long-term brain health. 

     

    Shared Risk Factors Linking Heart Disease and Cognitive Decline 

    Heart disease and cognitive decline don’t develop in isolation.  Many of the same biological and lifestyle elements that damage the cardiovascular system also affect how the brain ages Addressing them early and consistently can support both heart and brain health across the lifespan. 

    Common Shared Risk Factors:10 

    • High blood pressure (hypertension)
    • High cholesterol and dyslipidemia
    • Diabetes and insulin resistance
    • Chronic inflammation
    • Obesity and metabolic syndrome
    • Sedentary lifestyle
    • Poor diet quality
    • Smoking
    • Excess alcohol use
    • Genetic risk factors such as APOE4, which can interact with lifestyle and vascular health 

    These elements contribute to vascular dysfunction, metabolic stress, and inflammation — processes that affect blood flow and vessel integrity throughout the body Over time, this shared biological burden can weaken both cardiovascular function and the brain’s ability to maintain healthy cognition, showing why prevention strategies commonly overlap for heart and brain health.8,10 

     

    Heart-Healthy Lifestyle Habits That Protect Brain Function 

    Because the brain and heart share risk factors, strategies to prevent decline overlap as well Even modest lifestyle changes can improve vascular function, calm inflammation, and maintain long-term cognitive health. 

     

    How Exercise Supports Both Heart and Brain Health 

    Frequent exercise is one of the most powerful ways to support both heart and brain health.  Regular movement improves blood flow, strengthens the cardiovascular system, and supports oxygen and nutrient supply to the brain Research regularly links higher levels of physical activity to better cognitive performance and a lower risk of cognitive decline and dementia over time.11,12  

    How you can start today: Take a quick 10-minute walk, do stretches, or climb some stairs — and remember that consistency is key.  

     

    How Sleep and Stress Shape Brain Aging and Vascular Health 

    Chronic stress and poor sleep place significant strain on both the cardiovascular and nervous systems Sleep deprivation and prolonged stress are associated with elevated blood pressure, increased inflammation, and weakened cognitive function.13,14  Achieving reparative sleep (between 7-9 hours) and incorporating stress-management practices such as relaxation techniques or routine exercise can help protect heart and brain health. 

    How you can start today: Try a bedtime routine like dimming the lights, avoiding screens, or meditating at night to help your mind and body wind down. 

     

    Smoking, Alcohol, and Cardiovascular Risk to Brain Health 

    Smoking and high alcohol consumption are well-established risk factors for cardiovascular disease and are also linked to increased cognitive decline Both can contribute to vascular damage, inflammation, and impaired brain function over time.15  Reducing or eliminating these habits can greatly lower the risk for both heart disease and cognitive impairment. 

    How you can start today: Work on cutting back gradually Swap a drink for sparkling water and go for smoke-free days.  

     

    Eating for Vascular Health and Cognitive Support 

    Diet plays a central role in protecting cardiovascular and cognitive function.  Certain dietary patterns are consistently associated with better heart health and slower cognitive decline, such as the Mediterranean and DASH (Dietary Approaches to Stop Hypertension) diets.12,16  

    The MIND diet combines these proven eating patterns and prioritizes foods that help reduce inflammation, support vascular health, and protect cognitive function Studies show that greater adherence to the MIND diet corresponds with better cardiovascular and metabolic health, reinforcing its role in long-term heart and brain protection.17 

    Key components to a heart- and brain-healthy diet: 

    • Healthy fats, particularly from plant sources
    • Foods high in fiber to aid metabolic and vascular health
    • Anti-inflammatory food choices, rich in polyphenols
    • Reduced intake of highly processed foods and added sugars 

    How you can start today: Include a handful of berries, nuts, or some avocado during meals.  Simple additions can make a significant difference over time.

    The Proof is in Prevention 

    Periodic health screenings are a critical but often overlooked part of protecting brain health Monitoring blood pressure, cholesterol levels, and blood sugar can help identify vascular risk early, when interventions are most effective Managing these markers supports cardiovascular health and may help preserve cognitive function over time. 

    How you can start today: Check when your last blood pressure, cholesterol, or blood sugar screening was, and schedule your next one if it was over a year ago.
