There is growing evidence of a link between very early stages of brain and heart disease.
Several studies have found a correlation between brain health and heart health, with researchers suggesting that the two are closely related. In particular, some studies have found that people with heart disease are more likely to develop cognitive impairment or dementia later in life, and that changes in brain structure and function can be detected even in the early stages of heart disease.
Recent research has also focused on the relationship between brain health and cardiovascular risk factors such as high blood pressure, high cholesterol, and diabetes. For example, a study published in the journal Neurology in 2020 found that people with higher levels of blood pressure, cholesterol, and blood sugar in midlife had more brain shrinkage and more white matter damage in their brains later in life. Other studies have found similar associations between cardiovascular risk factors and early changes in brain structure and function.
While the exact mechanisms underlying the link between brain and heart health are not fully understood, researchers believe that factors such as inflammation, oxidative stress, and endothelial dysfunction may play a role. Overall, the evidence suggests that taking steps to maintain heart health, such as through a healthy diet, regular exercise, and managing cardiovascular risk factors, may also help to support brain health and prevent cognitive decline.
