She spent years trying to treat mast cell activation, Epstein–Barr, inflammation… and every immune protocol you can imagine.

Sometimes things would improve a little.�But it never stuck.

Because the real question rarely gets asked:
What’s controlling the immune system in the first place?

Your immune system isn’t operating on its own.�It’s regulated by your nervous system and brain.
The same brain centers that regulate autonomic function also influence immune responses. So when those control systems aren’t working properly, the immune system can become hypersensitive and overreactive.

That’s when people start experiencing things like:
• Histamine reactions�• Mast cell symptoms�• Food sensitivities�• GI dysfunction�• Cycles of inflammation that never fully resolve

In those cases, treating the immune system alone often turns into a cycle of elimination diets, supplements, and medications that provide temporary relief… but never solve the underlying problem.

Sometimes the real shift happens when you step back and ask a different question:
How is the brain regulating the immune system?
Because when that neurological control improves, many of those immune responses can begin to settle down.

If reading a few pages or having a simple conversation leaves you stuck in bed for hours… that’s not typical POTS physiology.

In many neurological cases, the problem isn’t just standing up. The problem is energy delivery to the brain.

When neurons fire, they’re supposed to signal for more blood flow so they can get oxygen and glucose. But after certain brain injuries, that communication breaks down.

This is called neurovascular decoupling.
The neurons are asking for fuel… but the blood flow never arrives.

So the brain struggles to keep up with even basic cognitive tasks, and the body compensates by raising heart rate.

The solution isn’t simply lowering heart rate.
It’s retraining the brain so blood flow and neuronal activity reconnect — gradually increasing stimulus so the brain can rebuild its energy capacity.

When that coupling returns, symptoms often improve and the compensation isn’t needed anymore.

You did the tilt table test.
�You got the diagnosis.

…but you still feel awful.

That’s because the conventional tilt table test is only measuring heart rate and blood pressure. What it doesn’t tell us is the question that actually matters:
Is enough blood reaching the brain?

When blood flow to the brain drops, the body compensates by increasing heart rate. So the high heart rate seen in POTS is often not the root problem — it’s the body’s attempt to keep the brain supplied with blood.

Using transcranial Doppler ultrasound during tilt testing allows us to measure blood flow directly in the brain. That changes everything.

Instead of chasing the symptom (heart rate), we can start identifying why the brain isn’t getting enough blood in the first place.

And when you find the mechanism, treatment becomes much more targeted.

A diagnosis like POTS tells us what the body is doing — not necessarily why it’s happening.

For many patients, the elevated heart rate when standing is the body trying to compensate for something deeper, often related to how the brain regulates blood flow.

When treatment focuses only on suppressing the symptom, people can stay stuck.

But when we start asking better questions about the underlying mechanism, new treatment pathways open up — and that’s often when patients who have struggled for years finally start moving forward again.

When people with ME/CFS hear the phrase graded exercise therapy, the instinct is often to run the other direction.

And honestly — that reaction makes sense.
The problem isn’t the concept of gradual capacity building. The problem is when exercise is applied like a generic algorithm, pushing the entire system instead of identifying the specific pathway that’s failing.

Recovery isn’t about forcing global workouts. It’s about finding the bottleneck — neurological, metabolic, autonomic, vestibular — and gently improving that system without exceeding the patient’s tolerance.

Capacity grows when the right system is challenged just enough.

Push the wrong system, and you crash.

Mold gets blamed for a lot of chronic illness symptoms online.
And while it can absolutely be a real trigger, it’s not always the root mechanism.
For many patients with neurological conditions, the bigger question is how the brain and nervous system are regulating the immune system and interpreting environmental signals.
When that system isn’t functioning well, the body can become overly reactive to things that others tolerate just fine.
So yes—remediation and detox can matter.
But sometimes the missing piece is helping the nervous system process and regulate those environmental inputs more effectively.
Because the goal isn’t just removing the trigger.�It’s restoring the system that’s supposed to handle it.

Ever feel dizzy in places that shouldn’t make you dizzy?

Sometimes it’s not the inner ear at all. It can be something as simple as patterns in your environment—grocery store aisles, busy carpets, tile floors, or passing scenery through a window.

The key question to ask:
• Does it happen just from looking?�• Or does it happen when your eyes and head move together?

That distinction helps determine whether the issue is coming from visual pathways, vestibular reflexes, neck input, or a combination of systems working together.

Once you understand the mechanism, you can finally start addressing the root cause.

Many people assume dizziness always comes from the inner ear.

But sometimes the problem is actually the communication between the inner ear and the brain that coordinates your eyes.

Here’s a simple trick that may help give you a clue:
• Cover one eye�• Look straight ahead�• Hold for about 5 minutes

If your body starts to relax or symptoms decrease, it may indicate that your eyes are not working together properly. In many cases this can reflect a central vestibular issue affecting eye coordination.

This can show up in conditions like:�• visual vertigo�• PPPD�• post-concussion syndrome�• vestibular dysfunction
It’s not a diagnosis — but it can be an interesting signal worth exploring further.
Try it and let me know what you notice.

Your brain lives in a dark box (your skull). It only knows the world through its "gauges." Hoemann (2019) proves that if your balance gauge is flickering, the brain builds a world of stress. We’re going to show you how to steady the gauges so your brain can finally construct a world of ease.

Most people assume dizziness always comes from the inner ear.
But sometimes the issue isn’t in the ear at all — it’s in how the brain interprets visual motion.

Crowded environments, fast-moving surroundings, scrolling screens, or even walking through stores can overwhelm the brain’s motion-processing systems. When visual information doesn’t align with signals from the body and balance system, the brain struggles to determine what’s actually moving.
That sensory mismatch can trigger dizziness, nausea, lightheadedness, and the unsettling feeling that your body and environment aren’t syncing properly.

For patients who’ve ruled out common vestibular causes, understanding how the brain processes visual input can be an important step toward recovery.

If medications alone were going to solve ME/CFS… many more people would already be better.
A recent study looking at ~3,500 ME/CFS patients using nearly 150 different treatment approaches uncovered something important:

ME/CFS isn’t one condition.
Researchers found distinct symptom clusters, including:�
• Autonomic / POTS-dominant�
• MCAS / histamine-dominant�
• Cognitive dysfunction-dominant

And those clusters respond very differently to treatment.
Which helps explain why one person improves on medications while another sees little change.
There’s also a key overlap between ME/CFS and POTS.
Both conditions often involve cerebral hypoperfusion — meaning the brain isn’t receiving adequate blood flow.

03/04/2026

POTS flare or ME/CFS flare… or both?
This is one of the most common (and confusing) questions.
The truth? There’s a significant overlap. Many people with ME/CFS experience POTS symptoms. Many people with POTS experience profound fatigue. The labels can blur.
One of the strongest physiological links between them is cerebral hypoperfusion — reduced blood flow to the brain. When the brain isn’t getting what it needs, symptoms like dizziness, fatigue, brain fog, and exercise intolerance can show up regardless of the diagnosis.
Instead of obsessing over the label, ask:�What’s the underlying mechanism?
When you test and understand what’s driving symptoms — blood flow regulation, autonomic dysfunction, oxygen delivery — treatment becomes much more targeted.
Less mystery. More clarity.�If you want a deeper breakdown, we’ve got long-form content on YouTube explaining how POTS and ME/CFS intersect.
