A Healthy Heart May Decrease Dementia Risk

New research has found that there may be a link between cardiovascular disease and Alzheimer’s.  Conducted at Vanderbilt University Medical Center, researchers found that those with reduced heart function were more likely to develop memory loss.  This study may then suggest that a healthy heart can possible prevent dementia down the road.

The Heart & Brain Relationship

The great news about these findings is that heart health is a controllable factor when it comes to one's dementia risk. Genetics and family history are obviously uncontrollable; however, choosing healthy lifestyle choices can positively affect heart health. A lifestyle that includes a healthy diet and exercise keeps your heart health on the right track.

The study, published in the journal Circulation, began with efforts dating back to 1948. The researchers were trying to identify risk factors associated with heart disease. For eleven years, more than a thousand participants were followed. Over this period of time, thirty-two participants were diagnosed with dementia and twenty-six of those thirty-two developed Alzheimer’s.

Why is there such a strong connection between heart health and dementia risk? Fifteen percent of the blood pumped from the heart goes to the brain. The older we get, however, the vessels in our brain are not as strong as they once were in maintaining a consistent level of blood to support the brain. This can negatively affect brain function and activity.
