INSIGHT

Dementia's Silent Development

Dementia develops over decades with virtually no symptoms, similar to heart attacks and liver problems.
Organs compensate until they can no longer, masking early signs.

INSIGHT

Retina as an Early Indicator

The retina, being nerve tissue connected to the brain, exhibits early signs of dementia.
Problems with vision, like night vision, central vision, floaters, and light sensitivity, can indicate dementia.

INSIGHT

Brain Inflammation and Microbes

Studies of cadavers' brains reveal a link between inflammation, cognitive deficits, and dementia.
A microbe commonly found in teeth has been discovered in the brains of Alzheimer's patients, suggesting a potential link with dental infections.

Surprisingly, one of the earliest signs of dementia involves the retina. There is a high correlation between problems in the retina and problems in the brain. Problems with night vision or central vision, floaters, and light sensitivity issues are the earliest signs of dementia.

Some people develop amyloid-beta plaquing on the retina and may experience problems differentiating shades of grey and other colors. Researchers have found high levels of microbes, typically found in the mouth, in the brains of Alzheimer’s patients.

When people die from dementia, it’s usually caused by an infection such as a UTI or lung infection. For some people, surgery can be too much on the body and lead to death. Some people with dementia have a slow, progressive degeneration of the brain to the point they’re bedridden and stop eating and drinking, which ultimately leads to death.

Focus on cleaning your brain and reducing inflammation for dementia prevention. The glymphatic system cleans the brain, mainly at night, which is one of the primary purposes of sleep. This system removes malformed proteins and plaquing and rejuvenates the brain.

Anything that inhibits sleeping may increase your risk for Alzheimer’s, heart attacks, strokes, cancer, blood sugar issues, and type 2 diabetes. Sleep apnea can also be problematic. You need 8 to 9 hours of sleep! Alcohol significantly interferes with REM sleep and is very damaging to brain health.

To prevent Alzheimer’s, you must flood the brain with oxygen. Exercise is one of the best ways to do this! Exercise stimulates the growth of brain cells and the hormone BDNF (brain-derived neurotrophic factor).

Adequate sun exposure and high amounts of vitamin D can help support healthy sleep.

A diet high in sugar and carbohydrates can starve your neurons. Brain cells love ketones! To get into ketosis, you must lower your carbohydrate intake. If you have any early signs of dementia, try taking ketones as a supplement or MCT oil. Niacin may also be helpful. Take 50 mg daily, slowly increasing to 500 mg per day.
