Summary
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.

| 0:00.0 | The number one early sign of dementia. |
| 0:03.3 | You've never heard about this before. |
| 0:04.9 | In fact, I just recently found out about it, and this involves everyone, especially if you |
| 0:09.5 | want to prevent the different types of dementia, Alzheimer's, etc. |
| 0:13.8 | I think most people know that the first symptom of a heart attack over 50% of the time is death |
| 0:19.4 | because there is no symptom. And the same thing with the liver. |
| 0:22.2 | There really is no symptoms until the later stages when sometimes it's too late. Well, guess what? |
| 0:27.1 | The brain is the same thing. It takes decades to develop dementia. And in the meantime, |
| 0:32.1 | there's virtually no symptoms except one, which I'm going to discuss. And this is because |
| 0:36.7 | the different organs, especially the |
| 0:38.3 | brain, just keep compensating over a period of time until they can't compensate anymore. And so the |
| 0:43.5 | earliest sign of dementia involves the retina. It's nerve tissue that is literally sticking out |
| 0:50.0 | of your skull in your eye socket. The retina has certain cells that pick up information from the |
| 0:55.5 | environment and it allows you to see. And so they found a very large correlation between |
| 0:59.7 | problems in the retina and problems in the brain. Specifically with the outer layer of the retina, |
| 1:05.5 | and then you have all sorts of issues with the eye itself. Problems with night vision, |
| 1:09.7 | problems with central vision, floaters, |
| 1:12.8 | light sensitivity issues, and a lot of times people will just, you know, get a new set of glasses, |
| 1:17.9 | and they may even develop something called amyloid beta placking on the retina itself at the end of the |
| 1:25.1 | video and also in the description, I'll tell you what test |
| 1:28.5 | would pick this information up. You also might notice problems with detecting different shades of |
| 1:34.6 | gray or even differentiate different colors as well. They also evaluated cadavers' brains. And so they |
