Possibly suffered a concussion? Here are 3 things that should be evaluated, but most think it's imaging and that's not part of an exam.

02/15/2026

If you’re dealing with dizziness, you’ve probably heard this before

“Your MRI looks normal.”
“Your labs are fine.”
“Maybe it’s just anxiety.”

But you still feel off.
Unsteady.
Lightheaded.
Disconnected.

Whether it started after a concussion, with POTS, or seemingly out of nowhere. Dizziness is rarely random.

Your brain has to constantly process information from your eyes, inner ears, and neck to keep you stable.

If even one of those systems is sending distorted information, your brain struggles to create a clear picture of where you are in space.

And that’s when dizziness happens.

Imaging doesn’t measure function.
- It doesn’t measure eye movements.
- It doesn’t measure balance integration.
- It doesn’t measure how your brain coordinates incoming information.

Functional testing does.

For many people, the problem isn’t that nothing is wrong.
It’s that the right things were never measured.

At Peak Brain and Body, we look at how these systems are communicating — not just whether a scan looks normal.

Because dizziness isn’t something you should have to just fight through.

And when the real driver is identified, stability becomes possible again.

If this sounds like you, you’re not crazy.
You’re likely just missing the right evaluation.

We treat patients from all over the Tampa Bay Metro and across the United States. International patients may also travel in.

For those who would travel in we offer intensives where over a short period of time most see a lot of progress.

What are symptoms that someone who experiences a concussion may have?

Happy Valentine's Day

Friendly reminder, there is nothing more important you can give a loved one then their health.

This isn't about medspa treatment, massages, or other very optional things that don't matter after a week.

It's about chronic headaches, fatigue, dizziness, brain fog, etc that routinely impacts their daily life.

If your loved one doesn't have any of those, then great use the money and do the traditional things. But if they routinely talk about those symptoms, then it's time for them to feel good.

Why does dizziness occur after a concussion?

If your provider doesn't understand this, then you won't get better

02/13/2026

If you've been diagnosed with POTS, this picture is about the extent of what you've been told.

Just add in rotating different medications: metoprolol/propranolol, midodrine, ivabradine, fludrocortisone and that's about it.

What if there is more that you can do?

After treating this extensively the past few years and in total over a decade, clinically I can tell you people are misled to accept less than what they are capable of.

It's not because the provider intends to, it's the model of treatment doesn't work.

When you switch the model from cardiology to understanding neurology and what impacts neurology you will routinely get your life back.

It all starts by understand where you are at so you can get a plan tailored to your unique needs.

Are you dizzy with simple movements?

Maybe you've suffered a concussion or diagnosed with POTS/dysautonomia, or not sure.

Here's what you should know

If you've been diagnosed with POTS or Dysautonomia, you may have realized that a lot of attention gets paid to managing heart rate and blood pressure.

While it's important to acknowledge these, you still don't find that medication management truly makes you feel much better.

At Peak Brain and Body we understand that changes to heart rate and blood pressure are just another symptom that individuals experience.

When you identify what causes nervous system dysfunction that's where not only do your vitals improve, but so does energy, brain fog, headaches, dizziness, and much more.

We go beyond the standard care for POTS as it doesn't work.

POTS?
Is it a neuro or cardiac issue, plus is that all that should be considered?
