What Is the Connection Between Heart Health and Dementia

When we think about heart health and dementia, we often consider them as separate issues. Heart health is about keeping our arteries clear and our heart pumping well, while dementia is about memory loss and cognitive decline. However, recent research has shown that these two health concerns are more connected than we might think.

The heart and brain are closely linked through the vascular system. The brain uses a significant amount of oxygen and energy, which it receives from the blood flowing through our veins. When our heart is healthy, it efficiently pumps blood to all parts of the body, including the brain, ensuring it gets the oxygen it needs to function properly. But if the heart is not working well, this can disrupt the supply of oxygen-rich blood to the brain, leading to problems with thinking and memory.

High blood pressure, high cholesterol, and other heart conditions can damage the delicate blood vessels in the brain. This damage can lead to reduced blood flow, which may result in cognitive decline and increase the risk of dementia. For instance, chronic high blood pressure can cause vascular dementia by damaging the blood vessels in the brain. Similarly, high levels of “bad” cholesterol have been linked to a higher risk of dementia.

The connection between heart health and dementia is not just about physical damage; there are also shared genetic and lifestyle risk factors. People who are at risk for heart disease due to genetics or lifestyle choices may also be at a higher risk for dementia. This suggests that taking care of our heart health could also help protect our brain health.

So, what can we do? Maintaining a healthy lifestyle, including regular exercise, a balanced diet, and managing stress, can help keep both our heart and brain healthy. By understanding the link between heart health and dementia, we can take proactive steps to reduce our risk of cognitive decline and ensure a sharper mind as we age.
