Use Your Bone-Brain Link To Sharpen Your Memory

Imagine if the strength of your bones held the key to the sharpness of your mind. It may sound far-fetched, but emerging research is uncovering a surprising link between bone density and brain health. While we often think of our skeleton as merely the framework that supports movement, scientists now suggest that weak bones could be an early warning sign of something far more concerning—dementia. Could your bone health predict your cognitive future? A groundbreaking study offers compelling evidence that maintaining strong bones may be just as crucial for your memory as it is for your mobility.

Key Takeaways

• Higher Bone Density, Sharper Mind: Research shows that individuals with high bone density tend to have better memory retention and a lower risk of cognitive decline.

• 42% Increased Dementia Risk: Those with low bone density were found to be 42% more likely to develop dementia, suggesting a deeper connection between bone loss and brain degeneration.

• Lifestyle Matters: Regular exercise, proper nutrition, and key supplements like Vitamin D3 and K2 can support both bone and brain health, potentially reducing the risk of dementia.

Why Bone Strength Could Determine Your Cognitive Future

When you think of your bones and your brain you might not consider that they are intimately linked. Of course, the brain tells your muscles how to move your bones, but that’s about it, right?

There’s a lot more to it, say researchers who are learning about the association between brain health and bone health.

This isn’t the first time I’ve cast a spotlight on the bone-brain connection. In the past, I shared the results of a study regarding the bone-derived hormone osteocalcin, which is necessary for both brain development and healthy brain and memory function. Now, a new study published in the journal Neurology, suggests that people with high bone density maintain sharper memories than those with weaker bones. If you have low bone density you’re at a 42 percent higher risk for dementia.¹ Over 55 million people worldwide have dementia, a number that’s expected to increase. Meanwhile, approximately ten million Americans have the bone-weakening disease osteoporosis, and another 44 million have low bone density, placing them at increased risk of bone fracture, and yes, dementia.²

The Surprising Link Between Your Bones And Your Brain

For this new study, researchers in the Netherlands evaluated health data and the X-rays of 3,651 people who participated in the large Rotterdam Study. They had an average age of 72. Researchers interviewed all the participants every four to five years and completed physical exams, including X-rays and screening for dementia.

At the beginning of the study, none of the participants had a dementia diagnosis. However, over the next 11 years, Dr. Mohammad Arfan Ikram and his team observed a surprising shift.

They found that 19 percent of the men and women went on to develop dementia. Furthermore, among the 1,211 people with the lowest bone density, 90 people developed dementia within ten years. Conversely, of the 1,211 people with the highest bone density, 57 developed dementia within ten years.

42 Percent Higher Dementia Risk If You Have Low Bone Density

So, after crunching the numbers and adjusting for age, gender, education, illnesses, and family history of dementia, researchers reported that those with weaker bones were 42 percent more likely to develop dementia.

Dr. Ikram explained, saying, “Low bone density and dementia are two conditions that commonly affect older people simultaneously, especially as bone loss often increases due to physical inactivity and poor nutrition during dementia.”

Dr. Ikram added that little is known about bone loss that occurs in the period leading up to dementia. “Our study found that bone loss indeed already occurs before dementia and thus is linked to a higher risk of dementia.” Dr. Ikram goes on to say further research is warranted to determine whether or not this is a coincidence linking these two common age-related conditions.

The Takeaway

I suspect there is a stronger link between brain and bone health than was once believed. I believe this is a reasonable finding because there are a few common denominators between dementia and bone loss. Both diseases are closely linked to age. Additionally, inflammation plays a role in both disorders. Diet, nutrition, and lifestyle influence both bone and brain health. And this is why I say it’s never too late to make your lifestyle a priority. For instance, incorporating plenty of physical activity, including bone-supporting resistance training, is essential. Eating a nutritious, well-balanced diet, and taking calcium, vitamin D3, and vitamin K2 supplementation can help, too. Finally, limit alcohol, prioritize sleep, don’t smoke, manage stress, and find ways to stay socially connected. Each of these diet and lifestyle changes can make a huge difference in your bone and brain health today and tomorrow.

Summary

A recent study published in Neurology suggests a surprising connection between bone density and brain health. Researchers found that individuals with lower bone density had a 42% higher risk of developing dementia over time. This discovery sheds light on the importance of bone health beyond just preventing fractures—it could also play a crucial role in preserving cognitive function. The study highlights how factors like physical activity, proper nutrition, and key supplements can influence both bone and brain health. These findings reinforce the idea that a holistic lifestyle approach may be vital in reducing dementia risk while strengthening the body and mind.

Frequently Asked Questions

How are bone health and brain health connected?

Research suggests that bone density is linked to cognitive function, with lower bone density associated with a higher risk of dementia. This may be due to shared factors like aging, inflammation, and lifestyle choices.

What role does osteocalcin play in brain health?

Osteocalcin, a hormone produced by bones, has been shown to support brain development, memory function, and overall cognitive health.

Can improving bone density reduce the risk of dementia?

While more research is needed, maintaining strong bones through exercise, proper nutrition, and supplementation may contribute to better brain health and lower dementia risk.

What lifestyle changes can support both bone and brain health?

Regular resistance training, a nutrient-rich diet, sufficient Vitamin D3 and K2 intake, avoiding smoking, managing stress, and staying socially active can benefit both bones and brain function.

Who is most at risk for both osteoporosis and dementia?

Older adults, particularly women post-menopause, those with a family history of osteoporosis or dementia, and individuals with poor diet and sedentary lifestyles are at higher risk.
