Managing these risk factors can help in preventing both heart disease and dementia. It’s crucial to adopt a healthy lifestyle to reduce these risks.
Impact of Heart Disease on Cognitive Decline

Heart Disease and Brain Health
Heart disease doesn’t just affect your heart; it can also impact your brain. When your heart isn’t working well, it can’t pump enough blood to your brain. This lack of blood flow can lead to cognitive decline. Adults with heart disease are at higher risk for faster cognitive decline in the long-term. This means that keeping your heart healthy is also good for your brain.
Long-term Cognitive Effects
Over time, heart disease can cause serious problems for your brain. Studies show that people with heart disease often experience more rapid cognitive decline. This means they might have trouble remembering things or thinking clearly. It’s important to take care of your heart to help keep your brain sharp as you get older.
Preventive Measures
The good news is that you can take steps to protect both your heart and your brain. Here are some things you can do:
- Eat a healthy diet
- Exercise regularly
- Manage your blood pressure and cholesterol
- Avoid smoking
By following these steps, you can reduce your risk of heart disease and help prevent cognitive decline.
Taking care of your heart is a two-for-one deal: it helps your heart and your brain stay healthy.
Role of Blood Flow to the Brain in Healthy Aging
Importance of Adequate Blood Flow
The health of the blood vessels in your brain is closely linked to your overall heart health. Blood flow to the brain is crucial because the brain, although it makes up just 2 percent of body weight, consumes 20 percent of the body’s oxygen and energy supplies.
Having a healthy heart ensures that enough blood is pumped to the brain, and healthy blood vessels enable oxygen and nutrient-rich blood to reach the brain so it can function normally.
Mechanisms of Blood Flow Regulation
Brain cells need a constant supply of blood and oxygen to work properly. Part of the role of the heart-brain link is to increase blood supply to the brain when it needs more energy and oxygen.
This function is performed by the cerebrovascular reactivity (CVR). Higher CVR is a good indicator of brain health while lower CVR can occur as a result of heart disease. Dr. Suri suggests lower CVR may lead to dementia.
Impact on Cognitive Functions
The body’s largest artery, the aorta, gets stiffer with age, and faster aortic stiffening in mid-life to older age is linked to markers of poorer brain health, for example:
- Lower brain blood supply
- Reduced structural connectivity between different brain regions
- Worse memory
Medical interventions and lifestyle changes made earlier in life could help to slow down arterial stiffening. In an aging society where we expect a near tripling in the number of people living with dementia by 2050, identifying ways to prevent or delay its onset could have significant societal and economic impact.
