Have you ever encountered persistent notions regarding brain health, perhaps believing them yourself? For example: Dementia is hereditary in my family; I can’t alter my fate. Or Diet and lifestyle lose their potency after a specific age; the damage is irreversible. Let’s delve deeper into these perceptions.
Your brain desires quality sleep
Consistent sleep and wake times along with a bedroom free of screens can enhance sleep quality. It’s also advisable to forgo that nightly drink, as alcohol can disrupt sleep patterns and may lead to brain shrinkage over time, even with minimal to moderate intake levels.
Oral health influences brain health
The state of our oral microbiome is linked to brain health and the risk of Alzheimer’s disease. The correlation is similarly observed in cardiovascular health; increased instances of dental issues can elevate the risk of dementia. Notably, our dietary habits significantly impact oral bacteria levels.
Adopting a Mediterranean-style diet, abundant in whole foods while minimizing ultra-processed items, is beneficial for maintaining a healthier oral microbiota. Furthermore, following the MIND (Mediterranean-DASH Intervention for Neurodegenerative Delay) diet for a decade, irrespective of age, has been connected to a 25% decrease in the likelihood of developing Alzheimer’s disease.
Is your hearing in decline?
Loss of hearing due to age can heighten the risk of cognitive impairment, cognitive decline, and dementia (though not Alzheimer’s specifically). Additionally, social isolation stemming from hearing loss contributes to an increased risk of dementia.
Mitigate the chances of early hearing loss by reducing exposure to loud environments and utilizing protective gear when necessary, such as at concerts.
Linking heart health to brain function
Maintaining cardiovascular health plays a pivotal role in ensuring brain health, a fact that is often overlooked. Evidence indicates that high blood pressure during midlife correlates with accelerated cognitive decline and an increased dementia risk. Fortunately, lifestyle strategies such as a whole foods diet and regular exercise can effectively manage high blood pressure while directly benefiting brain health.
While coronary heart disease (CHD) and diabetes serve as moderate risk factors individually, their combined occurrence heightens the risk of vascular dementia significantly. A history of CHD can raise the dementia risk by nearly 30%, and the risk doubles when heart failure is concurrent.
While these statistics may be concerning, there is a positive aspect: adopting healthier dietary and lifestyle choices can significantly enhance cardiovascular health, effectively reducing the likelihood of both heart and brain issues over time.
Foods that boost brain health
Incorporating a handful of blueberries into your daily regimen can bolster memory, decrease the chances of cognitive decline, and help lower systolic blood pressure (the upper figure).
A significant study revealed that eating dark leafy greens on a daily basis has the potential to slow age-related cognitive decline. Surprisingly, regularly consuming beans—often referred to as “superfoods”—is associated with a lower risk of cognitive decline.
The guidance is clear: adopt a plant-forward diet—exclusivity is not required—that is rich in polyphenols, proteins, and healthy fats from a variety of sources, including vegetables, fruits, coffee, tea, legumes, whole grains, and nuts and seeds, to help mitigate the risk of cognitive decline and neurodegenerative diseases.
Brain health supplements
Once basic health needs such as sleep, nutrition, and physical activity are addressed, consider herbal remedies and supplements to further support brain health:
- Sage, spearmint, and lemon balm may positively influence sleep, anxiety, and memory.
- Bacopa monnieri and Ginkgo biloba have historically been used to promote mental sharpness, although research findings on their cognitive benefits remain mixed.
- Coenzyme Q10 may offer neuroprotective effects, similar to N-acetylcysteine (NAC).
- Sulforaphane has the ability to cross the blood-brain barrier and may alleviate neuroinflammation, while lion’s mane mushroom has demonstrated neuroprotective properties in animal research.
