Your Brain Has a Retirement Plan. Are You Funding It?

You wouldn’t start saving for retirement after you retire. So, you shouldn’t wait until memory problems arise before taking steps to protect your brain.  

Cognitive health is built over decades. While genetics matter, lifestyle factors substantially reduce or delay the onset of dementia, even in genetically predisposed people.   

The Lancet Commission reports that up to 45% of dementia cases are preventable by managing risk factors throughout your life — identifying 14 modifiable risk factors that when addressed together, could cut dementia cases by nearly half.    

Those 14 factors include:   

1. Lower Education 

2. Hearing Loss 

3. Vision Loss 

4. Hypertension 

5. Obesity 

6. Diabetes 

7. High Cholesterol 

8. Smoking 

9. Excessive Alcohol Use 

10. Physical Inactivity 

11. Depression 

12. Social Isolation 

13. Traumatic Brain Injury 

14. Air Pollution 

Sleep is also essential to preserving cognitive health. Sleep apnea and other sleep disorders are associated with increased dementia risk.  

A 2025 U.S. POINTER study confirms the commission report, showing that a structured, higher-intensity approach involving exercise, nutrition, and intellectually challenging activities improves brain function in older adults.   

The Top 4 Investments 

Move Your Body 

What’s good for the heart is also good for the brain, especially physical activity. Exercise improves blood flow and decreases inflammation. 

Feed Your Brain 

There’s strong evidence that a diet rich in fruits, vegetables, olive oil, fish, and nuts — like the Mediterranean diet — can help protect your brain. Or the DASH Diet (Dietary Approaches to Stop Hypertension), which emphasizes green leafy vegetables, berries, and low sodium. The MIND diet brings these two together for a winning strategy. 

Challenge Your Brain 

Regularly using your mental capabilities builds up cognitive reserve, a buffer against brain aging. While achieving higher education early in life provides lasting benefits, it is never too late to invest. Learn a new language, engage in complex hobbies, or start playing music.  

Stay Connected 

Social isolation is a risk factor for many health problems, like smoking, obesity, and lack of physical activity. 

Starting Your Investment Plan 

The best time to begin was a few decades ago. The second-best time is today. 

• In your 30s and 40s: Build your foundation. Establish healthy diet and exercise habits, pursue education and stimulating work, and prioritize seven to nine hours of sleep. Manage cardiovascular risk factors like blood pressure and weight. 

• In your 50s and 60s: Intensify your efforts during this time, as midlife hypertension, obesity, and diabetes have their greatest impact on future dementia risk. Address hearing and vision deficits, stay socially connected, and maintain physical and mental activity.   

• In your 70s and beyond: Keep investing. Continue walking, surround yourself with loved ones, and nourish your body with healthy food. Stay mentally engaged. Protect yourself against falls and head injuries. Manage chronic medical problems. Finally, be sure to get recommended vaccines, especially shingles, pneumonia, and the flu. 

The Bottom Line 

Just as financial risks can never be completely eliminated, neither can the risk of dementia. You can, however, dramatically improve your odds by developing consistent, long-term habits that compound over time. Invest in your cognitive future for powerful returns, including decades of clear thinking, independence, and a more enjoyable life.
