Can You Prevent Alzheimer’s?

How do I prevent Alzheimer’s?

As a physician, this is a question I’m frequently asked.  Really, there’s no cut and dry answer. But there are some wrong answers.

When talking about Alzheimer’s, we often refer to amyloid plaques and tau tangles. The common belief is that these are the underlying cause of the disease – and that if you get rid of them, you’ll be cured.

But that theory has been proven wrong, over and over again.

First off, every time they’ve developed a drug to reduce levels of these proteins, it hasn’t work. Instead, these experimental drugs seem to make matters worse.

Second, autopsies show that elderly people who never had memory loss – and even had superior thinking skills late into life – have highly dense plaques and tangles in their brains. But they never showed a single symptom of Alzheimer’s.

What’s the difference between people with amyloid plaques who develop Alzheimer’s, and those who don’t?


Open your arteries, improve blood flow for a new health miracle...

Did you know your circulatory system has over 60,000 miles of arteries, veins and other blood vessels, if stretched end to end?

But as you age, your blood vessels undergo changes, which may cause them to stiffen, thicken and get clogged.

GOOD NEWS! Doctors have now identified a “Miracle Molecule” inside your arteries that helps OPEN your arteries and IMPROVE blood flow.

It’s what Dr. Valentin Fuster calls it, "One of the most important discoveries in the history of cardiovascular medicine."To you, that means...

  • Healthy blood pressure
  • Sharper mind and memory
  • Skyrocketing energy and muscular strength
  • Increased pleasure and passion in the bedroom
  • Improved circulation to every cell and organ in your body

Go here to discover a new natural way to significantly boost the levels of this miracle molecule in YOUR body NOW!

What Causes Alzheimer’s Related Inflammation?

The fact is, amyloid plaque and tau are produced by the brain to protect itself from inflammatory conditions that would harm it. But when high levels of brain inflammation continue, it drives the spread of misfolded plaques and tangles and, eventually, leads to dementia.

There are a lot of inflammatory factors in our lives. But some of the biggest contributors to Alzheimer’s disease include…

Poor sleep habits. The brain: Takes up two percent of the body’s weight and twenty percent of it’s energy needs, every day.

When you sleep it opens your brain’s ventricular highway. Cerebral spinal fluid flushes out all the damaging debris and oxidative stress that accumulates from metabolic processing and information gathering and transmission all day long, via the glymphatic system.

If you don’t get enough sleep, or if you wake up a lot during the night, this system can’t do its job. Your brain isn’t getting cleared of waste and creates an inflammatory state in your brain.

Central obesity. Visceral fat, which accumulates around the belly, is highly inflamed in obese patients. It produces large quantities of inflammatory cytokines which play a central role in the brain’s inflammatory response that results in Alzheimer’s disease.

Obese individuals with central obesity have about a 3.5 times increased risk of dementia. Even people who are at a healthy weight have an estimated two times higher risk if they are carrying around extra belly fat.

Diabetes. High blood sugar is a potential cause of Alzheimer’s because the sugar binds with what we know of as hemoglobin A1C to form what is called advanced glycation end products… AGES; misfolded proteins that add fuel on the fire of potential chronic systemic inflammation.

And the more hemoglobin A1C you have, the more misfolded proteins you’ll have – especially in your brain. This is why Alzheimer’s is often called type 3 diabetes.

Are You Suffering From...

  • Love handles and a pot belly
  • Romance that isn't what it used to
  • Forgetfulness and inattention
  • Low (or no) strength and endurance
  • A sex drive that's shifted into neutral...or worse

High homocysteine levels. This amino acid is normally present in the body. But when levels are high, it becomes highly inflammatory and has a toxic effect on the brain. The brain protects itself by producing more amyloid deposits and tau. Even moderately raised homocysteine can increase the risk of dementia up to 2.5 times in older people.

Leaky brain. I’m talking about a membrane called the Blood-Brain Barrier (BBB).  This barrier naturally has junctions — like doorways — that allow certain materials to pass in and out. It’s designed to keep the toxins and pathogens out of the brain.

Systemic inflammation can cause the actual neurovascular bundle’s membrane integrity to break down, allowing waste material to get in. This leads to neural inflammation that is associated with Alzheimer’s disease.

Knock Inflammation out of Your Brain

If Alzheimer’s is driven by inflammation, the key, then, is to drive inflammation out of your brain.

First, aim for a good night’s sleep, every night. If you’re not getting at least a solid seven hours a night, all of the damaging debris and oxidative stress you’ve accumulated in your glymphatic system during the day won’t get flushed out. Plus, poor sleep habits are linked with inflammation. This makes developing great sleep habits very important.

Get your metabolism in order. Obesity and diabetes go hand-in-hand. Get one under control and you’ll get the other under control.

Besides physical activity, one of the best ways to lose weight is to restrict the amount of time you spend eating food each day.  For example, I only spend about seven or eight hours every day eating.  The rest of the time I am fasting — only drinking clear liquids.

Of course, you need to eat healthy foods during your feeding hours. Add plenty of healthy, organic, plant-based foods to you diet and limit your consumption of junk foods and meat. Not only can this help with weight loss. These daily fasting periods give your body time to clean out inflammatory junk cells.

Lowering homocysteine levels is often as easy as taking a few supplements. Depending on your levels, your doctor will likely prescribe a B complex vitamin with sufficient B6, B12 and folic acid/folate daily to help lower this potentially toxic amino acid.

And what about that leaky brain?

Well, systemic inflammation, poor sleep, obesity, diabetes and high levels of homocysteine all contribute to leaky brain – all of the same things that lead to Alzheimer’s disease!

So when you begin to take care of the rest, it will take care of itself.
