Brain Health Starts with Heart: A Lifestyle Guide to Preventing Dementia

Dementia is affecting millions of people globally, and this number is projected to double by 2050. But there is hope — the World Health Organization points out that by changing our lifestyle, we can significantly reduce our risk of disease.

The key is: Protecting your heart protects your brain.

Research has found surprisingly similar roots between Alzheimer's disease and vascular dementia: high blood pressure, high cholesterol, diabetes, and obesity — these "culprits" that damage the heart similarly damage cerebral blood vessels, reduce brain blood flow, and lead to cognitive decline.

Four Core Prevention Strategies:

1. Move Your Body: At least 150 minutes of moderate-intensity exercise per week, such as brisk walking or swimming, can effectively reduce dementia risk.

2. Eat Right: Consume more vegetables, fruits, whole grains, nuts, and fish while reducing processed foods, added sugars, and saturated fats. Heart-healthy foods are "nutrients" for the brain.

3. Quit Smoking and Limit Alcohol: Smoking and excessive alcohol accelerate blood vessel damage, especially critical for those with memory problems.

4. Sleep Well, Connect, Reduce Stress: Adequate sleep, active social engagement, and emotional management have all been proven to protect cognitive function.

Even with a family history or existing mild cognitive impairment, changes made now can still buy precious "healthy time" for your brain. Every heartbeat works to supply oxygen to your brain.
