It’s exciting to see more and more experts embracing lifestyle as a powerful tool to prevent cognitive decline. After all, when it comes to brain health, it’s important to mitigate potential issues before they manifest with symptoms. Translation: With cognitive decline, it’s best to intervene as early as you can.
Enter neurologist Dale Bredesen, M.D., author of the New York Times bestselling book The End of Alzheimer’s. He has made it his mission to provide actionable advice on cognitive decline and help people truly optimize their brain health—regardless of their age or cognitive status.
On this episode of the mindbodygreen podcast, Bredesen rattles off some less obvious factors that can significantly affect your brain health. Make sure you have the below on your radar:
1.
Your oral microbiome
You might be familiar with how the gut microbiome affects basically every function in your body (including brain health), but did you know your oral microbiome is just as critical? It’s true: Your mouth, after all, is the gateway to your body and the beginning of your gastrointestinal tract. “So I recommend everyone check out your oral microbiome,” advises Bredesen. (He suggests using a service like MyPerioPath.) “Do you have P. gingivalis, T. denticola, prevotella intermedia, F. nucleatum? These organisms are being found in the brain’ they’re being found in the plaques of coronary arteries… These things are impacting us systemically1.”
Vitamin D is one impressive micronutrient: The sunshine vitamin influences not only brain development4 but also everyday brain function5; it even works to protect your brain as you age5. In fact, one meta-analysis6 conducted in 2019 that reviewed 11 studies on a total of 21,784 participants found significant associations between vitamin D deficiency and both dementia and Alzheimer’s disease.
It’s something Bredesen sees all the time in his own practice. “It’s surprisingly common to see people come in with cognitive decline and their vitamin D level is 19 or 20 [ng/mL].” For reference, a blood level of 30 ng/mL7 is often considered the minimum cutoff for “normal” vitamin D status, but many experts believe a level of at least 50 ng/mL is crucial to keep your body healthy and feel your best.

The takeaway
A few unsuspecting factors can play a significant role when it comes to brain health. Of course, you can supercharge your brain health in myriad ways (polyphenol-rich veggies, anyone?), so consider this another helpful list to have on your radar.
