Keeping your heart strong may be the key to preserving a younger, sharper brain, according to new research published in Alzheimer’s & Dementia. The study shows that people whose heart function is less than optimal—though not severe enough to be diagnosed as heart disease—face a higher chance of brain shrinkage and Alzheimer’s disease, particularly if they carry one or more copies of the APOE4 gene.

What the research found

Researchers examined participants with varying levels of cardiac output, a measure of how effectively the heart pumps blood. Those with reduced output displayed smaller total gray matter volumes, as well as decreased frontal and occipital lobe sizes. These brain regions are essential for information processing, memory, planning, movement, vision, and emotional regulation.

The link was strongest among the roughly 28% of participants who possess the APOE4 gene, a known genetic risk factor for Alzheimer’s. While the study does not claim causation, it highlights a clear association between sub‑optimal heart health and early signs of brain aging.

Practical steps to protect heart and brain

The authors stress that maintaining or improving heart health is a practical way to support brain vitality. Here are the lifestyle recommendations emphasized in the article:

• Adopt a plant‑focused diet that includes fatty fish while limiting red and processed meats, added sugars, and highly processed foods.
• Exercise regularly, aiming for at least five days a week of aerobic activity combined with strength‑training sessions.
• Manage stress through daily practices such as meditation, deep‑breathing, or prayer.
• Consider testing your ApoB levels and vitamin D3 status, and discuss a multivitamin/mineral supplement and bovine colostrum with a healthcare professional.
• Stay socially engaged by cultivating supportive relationships, volunteering, or pursuing hobbies that give a sense of purpose.

Why the advice matters for Texans

Heart disease remains a leading cause of death in Texas, and the state also faces a growing burden of dementia and cognitive decline among its aging population. By addressing heart health early, Texans can potentially reduce the personal and economic costs associated with neurodegenerative disease.

Dr. Michael Roizen, chief wellness officer emeritus at the Cleveland Clinic, underscores that “the heart‑brain connection is real, and simple lifestyle changes can make a big difference.” He encourages readers to view heart‑healthy habits as an investment in long‑term mental clarity and independence.

Take action today

Start by evaluating your current diet and activity level. Small, consistent adjustments—like swapping a sugary snack for a piece of fruit, taking a brisk walk after dinner, or setting aside five minutes for quiet reflection—can add up to meaningful improvements in both cardiovascular and cognitive health.
