Have you encountered long-held beliefs regarding brain health, perhaps ones you personally subscribe to? For example: Dementia is prevalent in my family; there’s little hope for prevention. Or Once you reach a certain age, diet and lifestyle changes have little impact; the damage is already irreversible. Let’s delve deeper into these notions.
Your brain desires quality sleep
Achieving restorative sleep may lower the risk of dementia development. Insufficient sleep has been implicated as a possible precursor to neurodegenerative conditions. Moreover, lack of proper rest can diminish our tolerance for stress and may escalate the likelihood of depression. While the correlation between depression and dementia remains somewhat vague in studies, there are indications pointing toward a connection.
Consistent sleep and wake times, along with maintaining a device-free bedroom, can enhance sleep efficiency. It could also be wise to forego that regular evening drink, as alcohol can adversely affect sleep and contribute to brain shrinkage over time, even with moderate use.
The correlation between oral health and brain wellness
The makeup of our oral microbiome plays a significant role in brain health along with the risk for Alzheimer’s disease, which also affects cardiovascular health. Increased tooth decay and loss can elevate the risk of dementia. Notably, our diet can influence oral bacteria.
Following a Mediterranean-style diet, which emphasizes whole foods and minimizes ultra-processed items, can lead to a healthier oral microbiome. Furthermore, adhering to the MIND (Mediterranean-DASH Intervention for Neurodegenerative Delay) diet for a decade, regardless of age, has been linked to a 25% lower risk of developing Alzheimer’s disease.
Can you hear me now?
Hearing loss linked to aging can heighten the risk of cognitive impairment and overall cognitive decline, though it does not specifically lead to Alzheimer’s disease. Additionally, social isolation stemming from hearing difficulties is another factor associated with a heightened dementia risk.
You can mitigate the chances of hearing loss or early-onset hearing challenges by reducing exposure to loud sounds and using protective gear whenever necessary (including at concerts!).
The link between heart health and brain health
The importance of cardiovascular health to brain wellness is frequently overlooked. Studies suggest a relationship between midlife high blood pressure and an increased risk of cognitive decline and dementia. Fortunately, managing high blood pressure can involve adopting a whole foods diet and engaging in regular physical activity, both of which directly support brain health.
While coronary heart disease (CHD) and diabetes each present a modest risk for dementia, the presence of both conditions amplifies the risk of vascular dementia. A history of CHD correlates with a nearly 30% increased risk of dementia, and that risk can double in cases of heart failure.
Although these statistics may be concerning, it is important to note that dietary and lifestyle changes can significantly enhance cardiovascular health, subsequently reducing the risk of both cardiac and brain disorders over time.
Foods that support brain function
Incorporating a handful of blueberries into your daily routine can boost memory, lessen the risk of cognitive decline, and help reduce systolic blood pressure (the higher value).
A significant study found that consuming dark leafy greens daily can decelerate age-related cognitive deterioration. Similarly, regularly eating legumes may lower the risk of cognitive decline.
The message is straightforward: strive for a plant-based diet (exclusively is not necessary) rich in polyphenols, proteins, and healthy fats sourced from an array of foods, including vegetables, fruits, coffee, tea, whole grains, and nuts and seeds, to mitigate the risk of cognitive decline and neurodegenerative disorders.
Supplemental aids
Once you have established foundational habits like sleep hygiene, exercise, and nutrition, you might explore herbal remedies and dietary supplements to bolster brain health:
- Sage, spearmint, and lemon balm may yield beneficial effects for sleep, alleviate anxiety, and enhance working memory.
- Bacopa monnieri and Ginkgo biloba have been employed for centuries to foster mental clarity, although there are mixed findings regarding their cognitive advantages.
- Coenzyme Q10 may serve neuroprotective roles, similar to n-acetylcysteine (NAC).
- Sulforaphane can pass through the blood-brain barrier and may mitigate neuroinflammation, while lion’s mane mushroom has shown promising brain-protection properties in animal studies.
