What Causes Brain Fog? A Systems-Based Look at the Root Causes

If you’ve ever found yourself walking into a room and forgetting why, struggling to find the right words during a conversation, or feeling like your brain is stuck in a haze—you’re not alone.

You are likely dealing with brain fog and have probably thought what causes brain fog?

“Brain fog” is one of the most common complaints we hear in our clinic, Peak Brain and Body a functional medicine and functional neurology clinic in Wesley Chapel. Some know it’s an issue they want addressed, but others aren’t sure if it’s just a normal part of aging. Yet despite how widespread it is, it’s often dismissed, misunderstood, or chalked up to aging, stress, or hormones. But here’s the truth:

Brain fog is not “just in your head.” It’s your body’s way of telling you that something deeper is off, but it’s non-specific. 

In this article, we’re going to explore six major systems in the body that can cause or contribute to brain fog—many of which are often overlooked by conventional healthcare. If you’re someone who’s tried supplements, changed your diet, and still feels “off,” this deep dive is for you.

What Is Brain Fog?

First things first: brain fog isn’t a diagnosis. It’s a symptom – a signal that something in your body is out of balance. It might show up as:

• Difficulty focusing or concentrating
• Forgetting common words or losing your train of thought mid-sentence
• Feeling mentally fatigued even after sleeping well
• Zoning out or spacing out during the day
• A sense that your brain is “in a cloud”

And while it’s common, it’s not always normal – especially when it starts affecting your daily life, your relationships, and your ability to work and connect with others.

Now let’s look at why brain fog happens and what your body may be trying to tell you. Remember brain fog is always a neurological symptom, but it may not always be due to poor brain health and may be the result of problems in other parts of the body.

So, what causes brain fog?

The Six Body Systems That Can Cause Brain Fog

1. Gastrointestinal (Gut) Health and Brain Fog

Your gut and your brain are intimately connected through what scientists call the gut-brain axis. The bacteria in your gut produce neurotransmitters, influence inflammation levels through metabolites known as short chain fatty acids, and communicate directly with your nervous system.

When something is off in the gut, your brain may be impacted.

Common gut-related contributors to brain fog:

• Dysbiosis: An imbalance in gut bacteria. You may have too many harmful bacteria or too few of the beneficial ones. This disrupts digestion, nutrient absorption, and produces inflammatory byproducts that can affect brain function.
• Leaky Gut (Intestinal Permeability): When the gut lining becomes too porous, it allows toxins, food particles, and bacteria to enter the bloodstream and trigger systemic inflammation, including in the brain.
• Processed Foods & Inflammatory Diets: Diets high in sugar, refined carbs, and additives fuel inflammation in both the gut and brain. For some over time, this leads to decreased mental clarity. For others, they may notice changes in brain function minutes or hours after eating foods or drinking certain things.

How to address it:

• Track your food intake for 7 days. Cut out ultra-processed foods and added sugars as a good starting point.
• Consider an elimination diet or Paleo-style eating plan (vegetables, high-quality proteins, healthy fats). Track how you feel with the dietary changes. If you try to reintroduce foods see if you have a negative change in any symptoms; if you do then it’s best to avoid those foods.
• If you’ve cleaned up your nutrition and symptoms persist, stool testing can evaluate your microbiome and identify dysbiosis, pathogens, or leaky gut markers. This allows you to receive a specific treatment tailored for you. 

2. Neurological Function and Brain Fog

Brain fog is a neurological symptom, meaning something is disrupting the way your brain functions. It could be:

• Old concussions (even ones from years ago). In our experience 90% of individuals who are still struggling with concussion issues have no clue it’s what is keeping them stuck.
• Neurological inefficiency (your brain is working too hard to complete simple tasks)
• Visual processing- the brain has to take in an enormous amount of information. This information is taxing on the brain. Problems with eye movement function such as gaze fixation, pursuits, saccades, and vergence can lead to brain fog.

Your brain uses more energy than any other organ. When it becomes inefficient – whether due to an old injury, eye strain, or abnormal sensory input – it starts to feel foggy.

Brain Testing & evaluation:

• Computerized eye movement testing (video oculography) evaluates gaze fixation, saccades, and pursuits. Nearly 99% of our patients have never had this test performed. It’s off in upwards of 75% of the individuals we see and is a big part of their inability to get the results they want until it gets addressed.
• Balance testing and qEEG (quantitative EEG) identify areas of neurological inefficiency.
• A thorough history can reveal concussions that may have been overlooked or dismissed.

Addressing neurological function isn’t just for athletes – it’s often the missing piece for those who have tried everything else such as hormones, b-vitamins, thyroid, and other things.

3. Cardiovascular Health and Brain Fog

Your brain relies on constant, efficient blood flow to function. If your cardiovascular system isn’t working well, your brain may be under-supplied with oxygen and nutrients.

Subtle cardiovascular contributors to brain fog include:

• High blood pressure or undiagnosed hypertension
• Hypotension such as seen in dysautonomia
• Elevated triglycerides or cholesterol
• Inflammatory markers like homocysteine
• Lipoprotein(a) and ApoB (which increase your risk of plaque buildup)
• Low omega-3 fatty acid intake

How to evaluate it:

• Full lipid panel including ApoB and Lipoprotein(a)
• Homocysteine levels
• Omega-3 to omega-6 ratio
• Coronary artery calcium (CAC) scan to assess plaque buildup

Even if you feel “fine,” silent cardiovascular issues could be stealing your brain’s clarity. It takes years for cardiovascular issues to manifest as something bad, prevention is key.

4. Immune System & Chronic Inflammation Contributing to Brain Fog

Chronic inflammation is one of the most common underlying causes of brain fog. When your immune system is out of balance, your brain function can suffer. The key is to identify what impacts the immune system. It should be noted that many of the things that have already been talked about also drive changes in the immune system.

Major immune contributors to brain fog:

• Chronic infections: Epstein-Barr virus, herpes virus, Candida, and gut infections that usually don’t cause fevers can cause chronic inflammation and drive brain fog.
• Mold exposure: Can cause inflammatory reactions in sensitive individuals who have an immune response. This is more than exposure as not everyone who is exposed will develop symptoms.
• Autoimmunity: Your immune system attacking your own tissues (including the brain). Common autoimmune conditions include: lupus, multiple sclerosis, hashimoto’s, rheumatoid arthritis, crohn’s, and ulcerative colitis usually all come with symptoms of brain fog.

How to evaluate it:

• Immune testing for mold (IgG, IgE antibodies to mycotoxins) is preferred over urinary screenings.
• ANA panel (anti-nuclear antibodies) and tissue specific autoimmune markers based on symptoms and history.
• Lab specific testing for chronic infections that is best performed via blood or stool testing depending on the pathogen.
• Autoimmunity is a spectrum. Many individuals will go years before they are diagnosed. Most get diagnosed at the point of tissue destruction versus the early stage of the disease process where autoimmune markers are present.

The earlier you detect immune dysfunction, the more you can do to prevent full-blown autoimmune conditions.

5. Musculoskeletal System and Brain Fog

Tension, misalignment, or dysfunction in the muscles and joints of your upper spine, neck, or jaw can contribute to pain and brain fog.

Key physical contributors:

• TMJ dysfunction (tenderness or tightness in the jaw)
• Neck misalignment or tension
• Poor posture from screen use

While chiropractic care can help in some cases, musculoskeletal issues are rarely the only cause of brain fog. But if you also have neck pain or headaches, it should be evaluated. If you see great results then fantastic, but if not remember there is more to the picture.

Self-check: Press gently where your jaw hinges, just below your temples. If it’s tender, you may benefit from TMJ therapy or manual work on those muscles.

6. Endocrine System (Hormones & Blood Sugar) and Brain Fog

Hormonal imbalances and blood sugar instability are major drivers of brain fog. 

Top endocrine contributors:

• Thyroid dysfunction impacts the rate at which the cells in the brain function. When the rate is slow, then brain fog is common. The most common cause of low thyroid is autoimmune and is known as Hashimoto’s.
• Sex hormone imbalance (estrogen, progesterone, testosterone). These hormones are for more than sexual development and having babies. They play a critical role in immune and neurological health. When these are low or out of balance the brain is routinely impacted.
• Insulin resistance or blood sugar imbalance. Blood sugar that is too high or low impacts brain health. You do not need to be diabetic in order for blood sugar issues to be causing brain fog. 

Lab work to ask for:

• Full thyroid panel: TSH, Free T3, Free T4, Total T3, Total T4, Thyroid antibodies
• Sex hormones: Free and total testosterone, estradiol, progesterone,  total estrogen. These have less value for females who have regular cycles. 
• Blood sugar: Fasting glucose, insulin, C-peptide, triglycerides, oral glucose tolerance test (OGTT). Blood sugar and insulin levels should be back to fasting levels 3 hours after eating.

If you feel tired or foggy after eating, your blood sugar may be on a roller coaster. Start by tracking how food affects your energy.

Post-Concussion Syndrome Treatment in Tampa: The Missing Link in Your Recovery

If you’re reading this, there’s a good chance you’re still living with the effects of a concussion—whether it happened recently or years ago. Maybe you’ve been struggling with symptoms like brain fog, fatigue, dizziness, or mood changes. Maybe you’ve tried physical therapy, chiropractic, medications, or supplements, and yet… something still feels off.

You’re not alone—and it’s not in your head despite the likelihood you’ve been told multiple times it’s from anxiety, depression, or that a concussion can’t impact you for that long. Concussions are the most common type of traumatic brain injury and are often classified as mild traumatic brain injury.

In this post, I’m going to walk you through everything you need to know about post-concussion syndrome treatment in Tampa—from how concussions are (often wrongly) diagnosed, to the most common myths, and most importantly, what proper treatment should actually look like.

Because what most people are getting isn’t sufficient? It’s not the full picture. And that’s why you’re not getting better. That is why Peak Brain and Body is a leader in post-concussion syndrome treatment in Tampa and beyond.

This is the information I wish someone had given my wife 15 years before we finally discovered the root cause of her daily symptoms. She shouldn’t of had to suffer with daily headaches amongst many other symptoms.

There is a video version here: https://youtube.com/live/zdA0fYzWMw4

Why I Care So Much About Concussions (And Why You Should Too)

This is personal for me.

My wife had three concussions in her younger years. For over a decade, she battled with brain fog, fatigue, dizziness, and mood swings. She went to a couple doctors and was told it was just hormones, puberty, or stress. Even if she brought it up to her parents, the reply was “you’ve already been to the doctor.” No one put the pieces together. No one ever said, “Hey—this might be from a brain injury.”

That changed when I was working in a brain injury clinic. She realized that the symptoms that individuals were having resolved on a daily basis were part of her everyday life. They were so common that she didn’t even mention them, because weren’t those symptoms that most people had? We finally did the right evaluations, uncovered what was missed, and began treatment that actually addressed her brain function. It was the beginning of her healing—and it changed the trajectory of my career.

Since then, I’ve dedicated my life to helping people who’ve been struggling silently for far too long. 

People like you.

People who know something’s wrong but can’t get clear answers or real solutions. People who’ve been dismissed or told “you’re fine” based on a 5-minute exam or a normal MRI. People who’ve been told to “just wait it out” or “it’s all anxiety.” People who’ve tried functional medicine are told maybe it was their thyroid, hormones, or gut health when in reality it was an unresolved concussion. In my experience, nearly 90% of those still struggling with concussion symptoms have no clue that is the driving factor for the symptoms they have. 

I see you—and I want you to know: there’s hope. And there’s help.

The Most Common Concussion Myths That Keep People From Healing

Let’s start with some hard truths—because these myths are harming people every single day. You’ve been told these from family, friends, co-workers, and even worse other medical providers:

“You didn’t lose consciousness, so it can’t be a concussion.”

False. About 90% of concussions don’t involve loss of consciousness. That’s not a requirement.

“You didn’t hit your head.”

Also false. A whiplash injury—like in a car accident or fall—is more than enough to cause a concussion. You don’t need a visible bump or bruise on your head. In our experience, concussions are the most undiagnosed and untreated injuries that occur in a car accident.

“Your imaging came back normal.”

This one makes my blood boil. A normal CT or MRI just means there’s no bleed or fracture. It says nothing about brain function or about a possible concussion. Most concussions won’t show up on those scans as they aren’t made to detect it. That doesn’t mean you’re okay, even if a provider says your imaging looks good and you are fine. This isn’t true and don’t fall for it.

“You just need to rest and wait it out.”

Maybe that made sense 20 years ago based upon our limited understanding of the brain. But if you’re still being told to sit in a dark room and “wait it out,” you’re not being given current, science-backed guidance. In fact, that kind of advice has been shown to delay your recovery.

“You’re just anxious or depressed.”

Yes, concussions can affect mood—but brushing off your brain-based symptoms as “mental health” issues without evaluating your brain is a huge disservice. We know that it’s very common to develop depression or anxiety after a concussion. We also know that pre-existing depression prolongs concussion recovery and tends to worsen symptoms. That doesn’t mean it is all from depression, but the way these issues interact with concussion recovery.

Post-Concussion Syndrome Symptoms

Maybe you’ve had a concussion and were told you’d bounce back in a few weeks—but here you are, months or years later, still not feeling like yourself.

Here are some of the symptoms we commonly see in people with undiagnosed or untreated post-concussion syndrome:

• Brain fog that makes it hard to think clearly or find words
• Fatigue that worsens throughout the day and doesn’t improve with rest
• Headaches or pressure in your head
• Difficulty focusing or remembering things
• Light and sound sensitivity
• Dizziness, motion sensitivity, or nausea
• Irritability, anxiety, or mood swings
• Sleep issues—either insomnia or waking up unrefreshed

If two or more of these symptoms got worse after your injury—or even if they were already present but intensified—your brain may be struggling to function normally. And you deserve to know why.

How Is a Concussion Diagnosed

Here’s how we determine whether your symptoms are linked to a past concussion:

1. A Clear Mechanism of Injury of Concussion

This could be a car accident, fall, sports collision, or any event involving a blow to the head or body that jolts the brain.

2. Clinical Signs of Concussion

Clinical signs would be findings that occur at the time of the concussion. This includes vomiting, loss of consciousness, confusion, and gross motor instability. You do not need to have these to be diagnosed if you have parts 1, 3 and 4.

3. New or Worsened Symptoms of Concussion

According to clinical guidelines, having two or more new or aggravated symptoms is enough to raise a red flag.

4. Objective Clinical Findings of Concussion

This includes eye movement testing, computerized balance assessments, and vestibular evaluations. (More on that in a second.)

5. No Better Explanation

If your symptoms don’t line up with another condition, and testing reveals brain dysfunction, a concussion diagnosis makes clinical sense—even without imaging abnormalities.

Here is a graphic from the American Congress of Physical Medicine and Rehabilitation for diagnostic criteria for MTBI. 

Why Most People Aren’t Diagnosed Properly For Concussion

Too often, people are told, “Your scans are normal. You’re fine.” They might get a quick check of reflexes and be sent on their way. It’s unfortunate that this happens, but most providers receive little to no training on concussions. 

Here’s what’s missing, objective testing:

Computerized Balance Testing

This shows how well your brain integrates signals from your eyes, vestibular system, and body. The platform measures how much you move on a firm and perturbed surface with eyes open and closed. Beyond this, evaluating tandem stance and one legged stance is also important.

Eye Movement Testing (Video Oculography)

We use specialized goggles to record your eye movements. Why? Because your eye movements are directly connected to brain function. It is important to measure gaze fixation, pursuits, saccades, anti-saccades, optokinetics, and spontaneous nystagmus. If you can’t smoothly follow a target, your brain isn’t processing information correctly and this will routinely cause a variety of symptoms. 

QEEG Brain Mapping

This measures your brainwave activity. While not diagnostic on its own, it’s a powerful way to measure progress and see how your brain is functioning. In the future, this testing will likely be more important as research will be able to correlate certain brainwave patterns with concussions.

Why Most Treatments Fail (And What You Actually Need)

Here’s what we see all the time: people try one therapy at a time. Maybe they did vision therapy for months, vestibular rehab, neurofeedback, or hyperbaric oxygen therapy to see some results but not actually recover.

But they didn’t get better.

Why?

Because concussions are complex. They don’t affect just one system. They affect multiple areas of brain physiology and immunology—including blood flow, inflammation, energy production, and brain connectivity resulting in oculomotor and balance changes.

So if you treat just your eyes… but ignore balance, inflammation, or the immune response? It’s not going to work.

You need a layered, integrated plan that addresses:

• Neurological dysfunction
• Brain energy production and mitochondrial health
• Blood flow and oxygenation
• Vestibular and visual processing
• Inflammatory and immune factors
• Your pre-existing health state before the injury

Think of it like trying to play your favorite song—but each instrument is playing solo. You need them all working together in harmony as that is the only way you get the results you want.

Post-Concussion Syndrome Treatment in Tampa at Peak Brain and Body 

At our clinic, we go beyond checklists and guesswork. Every treatment plan is custom-built based on detailed testing. And instead of treating one system in isolation, we stack therapies together in a sequence that makes sense for your brain.

Our Treatment Toolbox Includes:

• Oculomotor therapy is based on improving the brain’s ability to perform a variety of functions.
• Vestibular therapy to integrate the function of vestibular, visual, and cervical spine.
• Postural and neck retraining
• Photobiomodulation (laser therapy) to reduce inflammation and support cellular energy
• Brain-based cognitive training and hand-eye coordination drills
• Targeted supplementation and peptide therapy
• Functional medicine to address root issues like gut health, hormones, autoimmunity, or mold exposure

We do all of this in a way that’s dynamic—just like your brain. And it works.

Real Recovery Is Possible

If you’ve been told there’s nothing else you can do, I want to tell you this: That’s not true.

I’ve seen people who’ve been struggling for 5, 10, even 15 years start to recover—because someone finally asked the right questions and ran the right tests.

I’ve seen people go from canceling plans and calling off work… to being present with their families again. Getting their careers back. Enjoying life again.

And the best part? Most people don’t need lifetime care. They need the right care at the right time—tailored to their brain. The brain can change fast when it’s provided the right information and supported. 

You’re Not Broken. You’re Just Misunderstood.

If you’ve been told your symptoms are all in your head, or that you should have recovered by now—let me say this loud and clear:

You’re not crazy. You’re not lazy. And you’re not broken.

You’re dealing with a brain that hasn’t fully recovered. And once we understand where the disconnects are—we can start fixing them.

It doesn’t matter what you’ve tried in the past, our clinic is full of individuals who tried numerous other therapies before they finally came in and found answers and solutions.

Functional Neurology Tampa: The Future of Brain Health and Rehabilitation

In the ever-evolving landscape of healthcare, functional medicine has taken center stage in offering a more personalized, in-depth approach to wellness. But within this movement, one of the most transformative and underrecognized fields is Functional Neurology—a groundbreaking approach that holds the key to unlocking solutions for a vast array of neurological conditions and symptoms. You will learn there are many common symptoms that individuals don’t routinely associate with brain health but they actually are. 

At Peak Brain and Body in Wesley Chapel, Florida, Dr. Spencer Zimmerman stands at the forefront of this revolution. As one of the nation’s most sought-after practitioners who combines functional neurology with functional medicine, his expertise extends far beyond state lines—patients from across the country and even internationally travel to see him, seeking answers that conventional neurology has failed to provide.

Here is the video version: click here

What Is Functional Neurology?

Functional Neurology is an advanced, non-pharmaceutical approach to diagnosing and treating neurological dysfunctions. Unlike traditional neurology, which largely relies on MRIs, CT scans, and pathology-based diagnostics, functional neurology delves into how the brain is functioning rather than just identifying structural damage. By assessing eye movements, balance, coordination, cognitive function, and movement patterns, functional neurology evaluates the intricate connections within the brain to pinpoint dysfunction and develop targeted rehabilitation strategies.

Functional neurology is built on the foundation of neuroplasticity—the brain’s ability to adapt, reorganize, and heal itself based on stimulation. By leveraging precise rehabilitation techniques, functional neurology helps retrain the brain, optimize neural pathways, and restore lost function.

Who Can Functional Neurology Help?

Dr. Zimmerman and his team at Peak Brain and Body have treated thousands of patients suffering from a wide range of complex neurological conditions, including:

• Long COVID & Dysautonomia
• Postural Orthostatic Tachycardia Syndrome (POTS)
• Stroke Recovery
• Concussions & Traumatic Brain Injuries (TBI)
• Chronic Fatigue & Brain Fog
• Neurodegenerative Conditions (Parkinson’s, Early Dementia, Alzheimer’s)
• Chronic Migraines & Headaches
• Vertigo & Dizziness
• Neurodevelopmental Disorders (ADHD, Autism Spectrum Disorders)

Even if those with the diagnoses and symptoms above are told what is wrong, they are often left frustrated that there isn’t a lot that can be done. On the other side, many of these individuals are told that their labs and imaging are normal, often leading to them being sent to a mental health provider. 

If you’ve experienced this and have been told your tests are “normal” but you still struggle with symptoms, functional neurology may be the missing piece in your health journey.

How Does Functional Neurology Differ from Traditional Neurology?

One of the biggest misconceptions in healthcare is that there is only one approach to evaluating and treating the nervous system. In reality, traditional neurology and functional neurology take completely different approaches:

Traditional Neurology	Functional Neurology
Focuses on disease pathology and structural damage	Focuses on neurological function and performance
Relies on imaging (MRI, CT scans) and blood work	Uses in-depth neurological testing (eye movements, balance, cognitive function, QEEG)
Treatments focus on medications and surgery	Treatments involve targeted brain rehabilitation and neuroplasticity training
Often tells patients “there’s nothing wrong” if no pathology is found	Identifies and corrects neurological dysfunctions even if imaging is normal

Both of these approaches to brain health and function have a place as neither one is equipped to handle all neurological based symptoms and conditions.

Many patients leave traditional neurology appointments feeling unheard, frustrated, and stuck with no solutions. Functional neurology changes the game by addressing how the brain functions and finding ways to restore it.

What to Expect in a Functional Neurology Evaluation

At Peak Brain and Body, a functional neurology evaluation is a deep dive into your brain’s function, using the latest advanced neurological testing that most doctors don’t even know exist. These evaluations include:

1. Eye Movement Analysis (Video Oculography)

Your eye movements provide a direct window into your brain health. Using cutting-edge videooculography, we can detect dysfunctions in different areas of the brain, helping guide targeted rehabilitation.

2. Balance & Postural Testing (Computerized Balance Posturography)

A specialized computerized balance platform is used to assess postural stability and vestibular function. Poor balance can be an early indicator of neurodegenerative diseases and cognitive decline. Balance is also routinely off with long-covid, concussions, whiplash, strokes, dysautonomia, and postural orthostatic tachycardia syndrome. 

3. Quantitative EEG (QEEG) Brain Mapping

A QEEG measures brain wave activity to identify abnormalities in neural communication, helping tailor treatments for patients with conditions like brain fog, anxiety, PTSD, ADHD, and post-concussion syndrome.

4. Cognitive & Reaction Time Testing

By evaluating how quickly and accurately your brain processes information, we can detect subtle impairments in cognitive function before they become major issues.

5. Functional Neurological Exam

This involves assessing reflexes, coordination, dual-tasking abilities, and cranial nerve function, which reveals how different brain regions are communicating and working together.

Functional Neurology Treatments: Rewiring the Brain for Healing

Once dysfunctions are identified, the next step is highly targeted brain rehabilitation. Unlike protocol-based care (where every patient gets the same generic treatment), functional neurology is about precision—designing a program based on your brain’s unique weaknesses and strengths.

Common Functional Neurology Treatments Include:

• Oculomotor Therapy – Strengthening brain function by using a specific combination of eye movements.
• Vestibular & Balance Training – Restoring vestibular and cerebellar function to improve dizziness, vertigo, and coordination.
• Hand-Eye Coordination & Reaction Time Exercises – Enhancing cognitive flexibility and neural processing speed.
• Transcranial Magnetic Stimulation (TMS) – A non-invasive therapy that stimulates brain activity and helps depression, anxiety, insomnia, and much more.
• Neuromodulation & Brainwave Training – Using neurofeedback and light therapy to retrain the brain.
• Targeted Physical Exercise – Driving neurogenesis (new brain cell growth) and angiogenesis (new blood vessel formation) to optimize brain function to support treatments performed in the office.

The Evolution of Functional Neurology: Beyond Rehab

Early functional neurology focused primarily on rehabilitation, but the field has expanded to address the broader factors influencing brain health.

At Peak Brain and Body, Dr. Zimmerman integrates functional medicine into his neurological treatments, ensuring that underlying factors such as gut health, inflammation, hormones, immune function, and metabolic issues are addressed alongside neurological rehabilitation. This is the main reason Dr. Zimmerman went back to get his nurse practitioner degree even though he had already gone through Chiropractic school. 

This whole-body approach ensures that patients get the highest level of care and long-term success that functional neurology on its own may not achieve.

Why Patients Travel from Across the Country to See Dr. Zimmerman

Patients don’t just come to Peak Brain and Body from Florida—they fly in from all over the United States and beyond because of Dr. Zimmerman’s expertise, advanced diagnostic techniques, and groundbreaking treatment protocols.

When traditional medicine fails to provide answers, Peak Brain and Body is often able to deliver results.

Is Functional Neurology Right for You?

If you have been struggling with brain fog, dizziness, chronic fatigue, memory loss, headaches, concussions, or other neurological symptoms and have been told “everything is normal or nothing else can be done and you must wait it out,” functional neurology may be the answer you’ve been looking for.

At Peak Brain and Body, we go beyond symptom management—we uncover and correct the root cause of neurological dysfunction to help you regain control of your brain and body.

A Functional Medicine Approach to Chronic Fatigue Syndrome: Understanding the Root Cause

Chronic fatigue syndrome (CFS) is one of the most common reasons people seek medical care, yet traditional treatments often fall short. Many individuals feel dismissed or unheard after being diagnosed, with limited options for true recovery. Functional medicine, however, offers a root-cause approach, addressing the underlying drivers of CFS rather than just managing symptoms.

Dr. Zimmerman at Peak Brain and Body in Wesley Chapel is a leading expert in helping individuals find answers and solutions for chronic fatigue syndrome through a non-pharmaceutical approach.

In this article, we’ll explore what actually causes chronic fatigue syndrome, why traditional medicine struggles to treat it effectively, and how a functional medicine approach can lead to better outcomes.

Understanding Chronic Fatigue Syndrome in Tampa

What Is Chronic Fatigue Syndrome?

Chronic fatigue syndrome, also known as myalgic encephalomyelitis (ME/CFS), is a complex condition characterized by extreme fatigue that doesn’t improve with rest. It is classified as a syndrome, meaning it consists of a set of correlated medical signs and symptoms rather than a specific disease with one defined cause.

There are a variety of symptoms individuals may experience: fatigue, weakness, dizziness, lightheadedness, nausea, brain fog, headache, tachycardia, allergies, and frequently getting sick.

Chronic fatigue syndrome is more common in females than males and is typically diagnosed when symptoms persist for six months or longer after ruling out other conditions like iron deficiency, blood sugar imbalances, thyroid or diabetes as the sole cause. With that being said, these can co-exist and may play a role in chronic fatigue syndrome.

The Overlapping Conditions of Chronic Fatigue Syndrome

One of the key challenges in treating CFS is its overlap with other conditions. Postural Orthostatic Tachycardia Syndrome (POTS), for example, has significant symptom similarities, including dizziness, fatigue, brain fog, and immune dysfunction. Research shows that 95% of CFS patients experience worsening symptoms when moving from a seated or lying position to standing.We have a couple blog posts on POTS and you can read one here: POTS Blog Post.

Rather than viewing CFS as a single disease, it’s more helpful to see it as a multi-system dysfunction impacting neurological, immune, gastrointestinal, musculoskeletal, and cardiovascular systems. This is why individuals are sent to a variety of specialists, but also struggle to get better. By the end of this article you are going to have a greater understanding of what should be done.

What Causes Chronic Fatigue Syndrome?

The functional medicine approach to chronic fatigue syndrome starts with a fundamental question: What is driving the condition? As in, we know the symptoms these individuals experience, but why do these symptoms manifest to begin with? 

Several contributing factors can set off the cycle of chronic fatigue, including infections, neurological dysfunction, gut health issues, and immune dysregulation.

1. Pathogens and Chronic Infections Role in Chronic Fatigue Syndrome

Pathogens—including viruses, bacteria, fungi, and parasites—can play a significant role in the development and persistence of chronic fatigue. Some of the most common infectious triggers include:

• Epstein-Barr virus (EBV) – Often associated with reactivation in CFS patients. Note that most of the population has been exposed to EBV. The labs that would suggest an ongoing EBV issue include EBV early antigen IgG and EBV viral capsid antigen IgM.
• SARS-CoV-2 (Long COVID) – Can lead to post-viral fatigue and brain inflammation. Numerous studies have shown that the immune response can create a brain injury which explains why so many struggle with neurological symptoms after COVID.
• Herpes viruses – Including cytomegalovirus (CMV) and HHV-6.
• Lyme disease and co-infections – Bartonella, Babesia, and Mycoplasma pneumonia.
• Mold and mycotoxins – Often overlooked but significant in chronic fatigue cases.

Functional medicine focuses on identifying why the immune system is weakened, allowing these infections to persist, rather than just killing the pathogens. 

2. Neurological Dysfunction and Brain Inflammation

Chronic fatigue syndrome is often associated with neurological impairments, such as brain fog, dizziness, headaches, concentration, and word-finding difficulties. Research shows that inflammation in the body can cross the blood-brain barrier, triggering an immune response in the brain’s microglial cells. This leads to:

• Cognitive dysfunction (memory issues, poor concentration).
• Mood imbalances (anxiety, depression, irritability).
• Dysautonomia (heart rate and blood pressure irregularities).

Additionally, brain connectivity issues can impair energy regulation, making daily activities overwhelming for CFS patients. We will discuss below how to evaluate and treat brain connectivity issues. 

3. Gut Health and Chronic Fatigue Syndrome

The gut plays a crucial role in immune function and inflammation. Many CFS patients have dysbiosis (an imbalance of gut bacteria), which contributes to:

• Leaky gut (intestinal permeability) – Allowing inflammatory molecules to enter circulation.
• Low butyrate production – Reducing the gut’s ability to regulate inflammation.
• Inflammation spilling into the brain – Worsening cognitive symptoms and fatigue.

Addressing gut health through targeted nutrition, prebiotics, and probiotics can help improve overall energy levels and immune function.

Why Traditional Medicine Fails to Treat Chronic Fatigue Syndrome

In conventional medicine, treatment for CFS is typically symptom-based, relying on medications rather than addressing the root cause. Here’s a comparison of the traditional vs. functional medicine approach:

Symptom	Traditional Treatment	Functional Medicine Approach
Fatigue	Stimulants (Adderall, Modafinil)	Addressing infections, gut health, mitochondrial function
Brain Fog	Antidepressants, stimulants	Reducing neuroinflammation, improving brain connectivity
Pain	NSAIDs, muscle relaxants	Reducing systemic inflammation, targeted neurological exercises
Gut Issues	Laxatives, antidiarrheals	Restoring gut microbiome balance, healing leaky gut

Additionally, short office visits and reliance on insurance models make it difficult for conventional doctors to dig deeper into the complex factors contributing to CFS. Beyond this, there individuals are referred to different specialists to address symptoms, but the symptoms are just that. They don’t tell us why they are there and most specialists are frustrated and do not know where to turn because the places they are trained to look at aren’t providing solutions.

A Functional Medicine Approach to Chronic Fatigue Syndrome in Wesley Chapel

Functional medicine goes beyond symptom management by performing in-depth testing to find the underlying factors driving the symptoms that make up this syndrome. We are going to explore some that that providers will often use when utilizing a functinal medicine approach to chronic fatigue syndrome. With this testing the provider is able to create personalized treatment plans. Here’s how it differs from conventional care:

1. Comprehensive Testing

A functional medicine provider will assess multiple body systems using tests such as:

• Advanced stool testing – Identifies gut imbalances and infections.
• Blood panels: to evaluate endocrine, metabolic, and vascular factors.
• Mold and mycotoxin testing – Evaluates mold exposure’s impact on the immune system. There is a dispute on the best testing: urine vs blood. We utilize blood testing that measures the immune response to mycotoxins and believe it is superior to urine. Having mycotoxins in urine doesn’t mean it’s creating an issue for the individual.
• Immune function panels – Measures inflammatory markers and immune imbalances.
• Neurological testing – Includes video oculography to assess brain function. We will discuss this more below as over 95% of functional medicine providers do not measure brain health and function.

It is important to note that those with advanced training will not run every single test as they’ll use the exam to determine what should be done. Those without as much experience tend to over compensate by using an over abundance of labs to make up for clinical abilities. 

2. Targeted, Root-Cause Treatments For Chronic Fatigue Syndrome

Once underlying causes are identified, treatment focuses on restoring balance. This may include:

• Mitochondrial support – Improving energy production with key nutrients like CoQ10, acetyl-L-carnitine, and B vitamins; but this is always done in conjunction with nutrition changes.
• Brain connectivity therapy – Strengthening brain function through functional neurology techniques.
• Gut repair protocols – Using dietary interventions and microbiome support. 
• Detoxification support – Removing toxins that contribute to inflammation by avoiding exposure and using targeted nutrition to support detoxification pathways in the body.
• Neuroinflammation reduction – Utilizing lifestyle strategies to calm the brain’s immune response.

3. A Holistic, Patient-Centered Approach

Unlike traditional medicine, functional medicine providers take the time to listen, analyze the full history, and develop an individualized plan. Lifestyle changes such as nutrition, sleep optimization, movement, and stress reduction play a central role in recovery.

The Missing Link: Functional Neurology

While functional medicine addresses many underlying causes of chronic fatigue syndrome, brain connectivity remains an overlooked factor. Functional neurology bridges this gap by:

• Evaluating eye movements to detect neurological dysfunction by using videooculography.
• Using balance testing to assess brain-body communication through computerized balance posturography.
• Providing targeted exercises to restore brain function and energy regulation.

In our experience, when these test results are off you can take all the supplements in the world but it’s not going to yield great results. The brain uses 25% of the entire body’s energy supply and to get someone out of a state of chronic fatigue by ignoring brain dysfunction is very hard. 

For the best results, working with a provider who combines functional medicine and functional neurology can provide a more complete approach to healing.

Final Thoughts

Chronic fatigue syndrome is a complex, multi-system condition that requires a comprehensive and personalized approach. While traditional medicine focuses on symptom management, functional medicine identifies and treats the underlying root causes, including infections, neurological dysfunction, gut health, and immune imbalances.

If you’re struggling with chronic fatigue and conventional treatments haven’t worked, consider working with a functional medicine and neurology expert to uncover what’s really driving your symptoms.

The Power of Vitamin D for Brain Health: What You Need to Know

Vitamin D is routinely associated with bone health and sun exposure, but this sells the benefits of vitamin D far short of what it’s truly capable of. At Peak Brain and Body in Wesley Chapel, our functional medicine experts want you to understand the role of vitamin D for brain fog and overall health.

Emerging research continues to link vitamin D levels to cognitive function, mental health, and even neurodegenerative diseases like Alzheimer’s and Parkinson’s. In this article, we will explore the science behind vitamin D’s impact on brain function, mental health, and neurological disorders, as well as the best ways to maintain optimal levels for long-term well-being.

It’s important to understand as we go through this article that vitamin D is a great way to support many symptoms and conditions, but if it’s used as a stand alone treatment then the results are not what they’d be when combined with other targeted treatments.

Vitamin D and Mental Health: The Scientific Connection

A recent study found that higher levels of vitamin D are associated with improved physical function and a reduction in depressive symptoms. The research showed that adults with lower vitamin D levels exhibited more depressive symptoms, and individuals diagnosed with depression had significantly lower intake of vitamin D compared to those without depression.

This isn’t the first and won’t be the last research on vitamin D and mental health. It’s been researched beyond depression and this includes anxiety, ADHD, and bipolar.

This highlights the importance of adequate vitamin D intake, whether through diet, supplementation, or sun exposure, for maintaining mental well-being.

How Does Vitamin D Affect Mood?

Vitamin D plays a crucial role in mood regulation by influencing neurotransmitters like serotonin, which is often referred to as the “feel-good” hormone. Selective serotonin reuptake inhibitors (SSRIs), common medications for depression, aim to increase serotonin availability in the brain. These are some of the most prescribed medications, but despite that the mental health crisis is continuing to worsen. Research suggests that vitamin D may naturally enhance serotonin synthesis, offering a non-pharmaceutical approach to improving mood and reducing depressive symptoms. Plus, there are no side effects of vitamin D compared to SSRIs which routinely come with side effects. We have other blogs which focus on different mental health diagnoses and won’t spend more time on it here. Click to learn more about depression 

Mood and mental health disorders go beyond serotonin levels though. Numerous research has looked at the contribution of inflammatory and immune mediated changes that drive these disorders and symptoms.

Vitamin D helps regulate inflammatory cytokines, which are often elevated in individuals suffering from depression and other mood disorders. Lowering inflammation can have a profound impact on mood stability and mental resilience.

Vitamin D For Brain Fog and Overall Health

Cognitive decline is one of the biggest fears as people age. Millions of individuals are living in a state of pre-dementia and it’s estimated over 90% have no clue they have mild cognitive impairment. With mild cognitive impairment and dementia rates rising, researchers have been investigating how vitamin D influences brain health.

A study on aging rats showed that higher vitamin D levels enhanced hippocampal synaptic function. The hippocampus, a brain region critical for learning and memory, relies on strong synaptic connections to function effectively. Rats with sufficient vitamin D levels performed better on complex memory tasks, suggesting that vitamin D may improve cognitive aging and reduce the risk of dementia.

Vitamin D and Alzheimer’s Disease

Research indicates that vitamin D may help prevent Alzheimer’s disease by reducing amyloid-beta production and enhancing its degradation. Amyloid-beta is the protein that accumulates in the brains of individuals with Alzheimer’s, leading to cognitive decline. Additionally, vitamin D increases levels of brain-derived neurotrophic factor (BDNF), which supports neuron survival and enhances synaptic plasticity—key factors in preventing cognitive decline.

Vitamin D and Parkinson’s Disease

For those concerned about Parkinson’s disease, vitamin D has shown promising neuroprotective effects. Research demonstrates that adequate vitamin D levels can reduce alpha-synuclein, the protein associated with Parkinson’s disease. It also increases dopamine neuron survival, helping to mitigate symptoms of the condition.

Vitamin D and Stroke Recovery

Strokes are a leading cause of death and disability, and vitamin D plays an important role in neuroprotection and recovery. Studies show that vitamin D helps:

• Reduce inflammation post-stroke
• Support neuron survival
• Improve motor function recovery

Since strokes can cause widespread brain damage, ensuring optimal vitamin D levels may contribute to a better recovery outcome.

Vitamin D Deficiency: How Much is Enough?

Many individuals take vitamin D routinely because they’ve heard about the health benefits, but how do you know you are getting enough? This is why testing is essential. The definition of vitamin D deficiency varies among different health organizations, but general guidelines suggest:

• Deficiency: Below 30 ng/mL
• Insufficient: 30-50 ng/mL
• Optimal: 50-75 ng/mL

My personal preference is if someone has immune issues including getting sick frequently, autoimmune disease, or neurodegeneration they should shoot to be on the higher end of 70-80 ng/mL. When we talk about these optimal ranges this is what many in functional medicine are shooting for as we understand traditional values are not meant for optimal health.

In traditional medicine, individuals with low vitamin D levels are often prescribed a high-dose regimen, such as 50,000 IU once a week for a few months. Depending on the provider the levels will be rechecked or not, but it’s not something routinely done. It’s crucial to continue monitoring levels since temporary supplementation does not guarantee reaching an optimal level or long-term sufficiency.

For ongoing maintenance, many experts recommend daily doses of 2,000-5,000 IU, depending on individual absorption rates, lifestyle factors, and geographic location. Once again, the ongoing dosing should be based off lab values because in our experience there isn’t an exact dose for every individual.

Can You Take Too Much Vitamin D?

Vitamin D toxicity is rare but can occur with extreme supplementation (e.g., 20,000+ IU per day for extended periods). Excess vitamin D leads to hypercalcemia, which can cause kidney stones, nausea, and other complications. This underscores the importance of regularly checking vitamin D levels to determine appropriate dosing.

Maximizing Vitamin D Absorption

1. Get Regular Sun Exposure

Your skin synthesizes vitamin D when exposed to sunlight, making outdoor activity an excellent way to maintain healthy levels. Aim for 10-30 minutes of midday sun exposure on bare skin several times a week, depending on skin type and geographic location. Despite this recommendation, in our experience sun exposure is not enough on its own to get optimal vitamin D levels despite what many claim.

2. Eat Vitamin D-Rich Foods

While it’s difficult to get sufficient vitamin D from food alone, the following sources can help:

• Fatty fish (salmon, mackerel, sardines)
• Egg yolks
• Beef liver
• Fortified dairy and plant-based milks

3. Take a High-Quality Supplement

Vitamin D3 (cholecalciferol) is the most effective supplement form. We prefer to use liquid or a liposomal form to facilitate absorption. There is some thought that pairing it with vitamin K2 may further enhance benefits, as K2 helps direct calcium to bones and away from arteries. In our experience even without K2, individuals are routinely able to achieve optimal vitamin D levels.

4. Monitor Your Levels

Regular blood testing ensures that you’re not deficient or exceeding safe levels. Individual needs vary, so personalized dosing is key. Initially checking levels every 3 months works best in our experience.

Final Thoughts: The Big Picture on Vitamin D and Brain Health

Vitamin D is more than just a bone health booster—it’s a powerful neuroprotective agent that supports mental health, cognitive function, and neurological resilience. With links to depression, dementia, Parkinson’s, and stroke recovery, maintaining optimal vitamin D levels should be a top priority for anyone invested in long-term brain health.

While vitamin D alone is not a magic bullet, it plays a crucial role in a comprehensive brain health strategy. Pairing adequate vitamin D intake with a nutrient-rich diet, physical activity, and proper sleep can significantly impact cognitive function and overall well-being.

Key Takeaways:

• Low vitamin D levels are linked to depression and cognitive decline. 
• Vitamin D for brain health may help prevent Alzheimer’s and Parkinson’s disease. 
• Deficiency is common—regular testing and supplementation may be needed.
• Sun exposure, diet, and supplements can help maintain optimal levels.
• If you’re concerned about your vitamin D levels, consider getting tested and working with a healthcare professional to develop a personalized strategy for optimal brain health.

What Causes Dizziness: Causes, Types, and How to Get Relief

Dizziness is a common yet frustrating symptom that can disrupt daily life, making it difficult to function at work, engage in activities, and even complete simple tasks. Many are trying to find out what causes dizziness and Dr. Zimmerman at Peak Brain and Body in Wesley Chapel, Tampa area, have helped many complex dizziness cases using an integrative medicine approach that combines both functional medicine and functional neurology.

Many people struggle for months or even years to get answers because they don’t know where to look or what questions to ask. If that sounds like you, keep reading—we’re going to break down everything you need to know about dizziness, its causes, and how you can take steps toward recovery. This is going to help you understand why some people do well with one treatment, but others don’t respond at all. Individuals can have predictable results, but knowing what you’re looking at is the first step. 

What is Dizziness?

Dizziness is a broad term that can mean different things to different people. Some describe it as feeling lightheaded, off-balance, or like the world is shifting around them. Others experience a sensation of spinning, known as vertigo. Understanding the difference is critical because using the wrong terminology could lead to misdiagnosis and ineffective treatment.

• Vertigo: A rotational sensation where either you feel like you are spinning, or the world around you is spinning.
• Dizziness: A general feeling of unsteadiness, lightheadedness, or imbalance without a spinning sensation.

The distinction matters because the underlying causes and treatment approaches vary based on the type of dizziness you’re experiencing. Unfortunately many providers will not ask their patients to specify exactly what they mean and this can lead to a lot of frustration. 

The 5 Key Causes of Dizziness

In this section we are going to discuss in detail what causes dizziness and set a framework for finding answers. Dizziness is a brain-based issue, meaning that if your brain isn’t processing signals correctly, you’re going to feel off balance. There are many reasons why the brain may not process signals correctly, but here are the five categories that cause dizziness:

1. Inflammation

Inflammation in the brain or the body can impact your nervous system, leading to dizziness. When you have inflammation it can disrupt how well the brain is connecting. Common sources include:

• Food sensitivities: Gluten, dairy, and ultra-processed foods can cause systemic inflammation.
• Infections: Viral, bacterial, or fungal infections, including mold exposure, can contribute to dizziness.
• Allergies: Seasonal allergies can create congestion in the eustachian tubes, impacting balance and stability.

2. Metabolic Issues

Your body’s metabolic processes directly affect how well your brain functions. When you hear the term metabolic, think about how efficient something is. For example, an efficient car gets great mileage. An efficient brain and body produces and uses energy extremely well. Key metabolic causes of dizziness include:

• Anemia: Low iron levels reduce oxygen delivery to the brain, leading to dizziness. A complete iron panel (including ferritin and iron saturation) is essential for proper diagnosis. Many will only have a CBC and told things are normal, but this will miss many individuals who have iron deficiency.
• Thyroid Dysfunction: Hypothyroidism or hyperthyroidism can contribute to dizziness. Proper thyroid testing should include TSH, T4, T3, Free T3, Free T4, and thyroid antibodies.
• Blood Sugar Imbalances: Both high and low blood sugar levels can cause dizziness. Symptoms of dysregulated blood sugar include energy crashes after meals or sudden surges in energy.

3. Musculoskeletal Issues

Your neck and spinal alignment play a significant role in balance. Dysfunction in these areas can cause dizziness due to poor communication between the cervical spine and the brain. 

• Cervical Spine Dysfunction: Poor posture, injuries, or surgeries in the neck can lead to dizziness.
• Muscle Imbalances: If the muscles around your neck send incorrect signals to your brain, it can create instability as it creates confusion within the brain. 

For some of these individuals they do well with Chiropractic or Physical Therapy, but others will be made worse.

4. Vascular Issues

Proper blood flow is critical for brain function. When blood flow is disrupted, dizziness can occur.

• Blood Pressure: If blood pressure goes too high or low then dizziness is a common symptom.
• Dehydration: A lack of fluids can cause dizziness and lightheadedness.
• Circulatory Problems: Conditions affecting the heart or blood vessels can impair blood flow to the brain, leading to dizziness.

5. Neurological Causes

Dizziness is ultimately a neurological issue, meaning that problems within the nervous system can be a major cause.

• Dysautonomia/POTS: A condition where the autonomic nervous system fails to regulate blood pressure and heart rate properly, leading to dizziness upon standing.
• Vestibular Dysfunction: The inner ear plays a crucial role in balance. If the vestibular system is impaired, dizziness and vertigo can result.
• Concussions and Brain Injuries: Even mild concussions can lead to dizziness for months or years if left untreated.
• Stroke & Multiple Sclerosis: More severe neurological conditions such as stroke and MS can impact balance and coordination.

As you are probably gathering by know, when someone wants to know what causes dizziness the answer isn’t black and white. Some individuals only have one of the components from above, but many others will have overlapping components that have to be addressed as a complete unit.

How to Get Relief from Dizziness

If you’re experiencing dizziness, the key to relief is identifying and addressing the root cause. Here are some steps you can take:

1. Get Proper Testing: Functional Medicine Labs in Wesley Chapel | Tampa FL

Most traditional doctors only check basic bloodwork, but you may need more comprehensive testing, including:

• Iron panel (Ferritin, TIBC, Iron Saturation, Serum Iron)
• Thyroid panel (TSH, Free T3, Free T4, Thyroid Antibodies)
• Comprehensive Metabolic Panel (CMP)
• Inflammatory Markers (CRP, Homocysteine, ESR)
• Functional Neurological Evaluation

A functional neurological evaluation for dizziness includes videooculography, computerized balance posturography, and a comprehensive physical examination that reveals what MRI and CT scans don’t. It’s why we see so many individuals finally get answers after they’ve been told nothing is wrong or the provider didn’t know what could be done.

2. Address Inflammation

• Eliminate inflammatory foods (processed foods, gluten, dairy, excess sugar).
• Reduce exposure to mold, allergens, and environmental toxins.
• Consider anti-inflammatory supplements such as omega-3s and curcumin.

3. Support Your Metabolism

• Ensure adequate iron, B vitamins, and thyroid support based off lab values.
• Balance blood sugar by eating protein-rich, fiber-dense meals.
• Stay hydrated with adequate electrolytes.

4. Improve Neck and Postural Health

• Seek chiropractic care, physical therapy, or massage if musculoskeletal issues are contributing to dizziness. If this helps you, then fantastic and keep going. If it’s not helping you or makes you feel worse then know there is more to the story and a more in-depth evaluation and treatment is necessary.
• Work on neck exercises and posture correction to optimize brain-body communication.

5. Strengthen Brain & Nervous System Function Utilizing Functional Neurology

• Perform eye and vestibular exercises under professional guidance.
• Targeted neurological therapy integrating cognition, hand-eye coordination, reaction time, and balance.
• Avoid excessive caffeine or stimulants that could worsen symptoms.

Final Thoughts: Taking Control of Your Health

If you’ve been struggling with dizziness for months or even years without answers, it’s time to take a different approach. Many providers don’t receive the training necessary to diagnose and treat complex dizziness cases properly. That’s why knowing the right questions to ask and seeking the right type of care can make all the difference.

If you want to dive deeper into what’s causing your dizziness and get real solutions, consider working with a specialist trained in functional neurology and functional medicine. You don’t have to keep suffering—answers are available. We will help you identify what causes dizziness for you, because as we’ve covered there are many factors that contribute to dizziness and it’s not the same for everyone.

Dysautonomia and POTS Treatment| Peak Brain and Body | Tampa and Wesley Chapel FL

Dysautonomia, POTS and Chronic Fatigue – Why You Have Dizziness, Headaches, and Other Common Symptoms

This may be the first time you’ve heard the phrase Postural Orthostatic Tachycardia Syndrome (POTS Syndrome) or you’ve been battling this condition for years and are struggling to find answers. Dr. Zimmerman at Peak Brain and Body has helped many in Tampa, FL and beyond get their lives back through advanced testing and treatment for Postural Orthostatic Tachycardia Syndrome (POTS). This blog is going to provide insight into not only what POTS and chronic fatigue are but why treating it as a cardiovascular-based condition fails so many.

Postural Orthostatic Tachycardia Syndrome (POTS) is more than just feeling dizzy when you stand up. It’s a complex neurological disorder that disrupts the body’s ability to regulate blood flow, leading to a cascade of symptoms that affect daily life. If you’ve been struggling with unexplained fatigue, dizziness, heart palpitations, gut issues, or even brain fog, this could be the missing piece of your health puzzle.

There is also a YouTube version of this: watch here

What Is POTS?

POTS is a form of dysautonomia, meaning it involves dysfunction in the autonomic nervous system—the system responsible for controlling involuntary functions like heart rate, blood pressure, digestion, and temperature regulation. It primarily affects women, with an estimated 80% of cases occurring in females.

The defining characteristic of POTS is an excessive increase in heart rate (by 30 beats per minute for adults, or 40 beats per minute for teens) within 10 minutes of standing, without a significant drop in blood pressure. If blood pressure does drop significantly, then it falls under a broader category of dysautonomia rather than POTS specifically.

POTS vs. Dysautonomia: What’s the Difference?

Dysautonomia is a broader term referring to dysfunction in the autonomic nervous system. POTS is a specific subtype of dysautonomia, characterized by increased heart rate upon standing without major blood pressure drops. If blood pressure does drop significantly, then the condition falls under categories like orthostatic hypotension rather than POTS.

While all POTS patients have dysautonomia, not all dysautonomia patients have POTS. Think of it like this: If dysautonomia were a car brand, POTS would be one specific model. Understanding this distinction is crucial because treatment approaches will differ when you see a traditional medical provider. It doesn’t matter as much when we look at non-traditional approaches which you’ll understand a lot more as you progress through this article.

Who Gets POTS and Why?

Over 3 million Americans are estimated to have POTS, and cases have skyrocketed, especially following COVID-19. It is important to note that it existed before COVID-19, but it wasn’t a routinely accepted diagnosis. This lead to many individuals who’ve dealt with it in the past to not receive a diagnosis. While COVID-19 infection is known to cause POTS or dysautonomia, it’s not the only thing. Other known triggers include:

• Viral infections (including flu and COVID-19)
• Concussions and brain injuries (including mild concussions that were dismissed)
• Autoimmune conditions (POTS can be an autoimmune-driven disorder)
• Chronic migraines (which can be both a cause and an effect of POTS)
• Surgery and prolonged bed rest
• Mast cell activation syndrome (MCAS)
• Vaccine side effects
• Hormonal shifts (such as menstruation and perimenopause)
• Genetic disorders like Ehlers-Danlos Syndrome (EDS) (particularly hypermobile EDS)

Symptoms of POTS: More Than Just Dizziness

POTS affects multiple body systems, making it difficult to diagnose and manage. Common symptoms include:

• Cardiovascular: Palpitations, fainting, feeling lightheaded, Raynaud’s syndrome (cold, discolored hands and feet)
• Neurological: Brain fog, headaches, dizziness, blurry vision, vertigo, ADHD-like symptoms, anxiety
• Gastrointestinal: Nausea, bloating, constipation, diarrhea, irritable bowel syndrome (IBS)
• Musculoskeletal: Weakness, joint pain, hypermobility, muscle fatigue
• Endocrine: Menstrual cycle irregularities, extreme fatigue, heat intolerance

Many POTS patients find themselves visiting multiple specialists—cardiologists, neurologists, endocrinologists—who only focus on one system. The issue? POTS impacts multiple systems at once. The symptoms above may be associated with the system above, but this is not the underlying reason for the array of symptoms that individuals have. Without a whole-body approach, treatment often falls short and many are left frustrated.

Why Standard Medical Approaches Fall Short

Most POTS patients are given five main recommendations:

1. Increase salt intake
2. Wear compression stockings
3. Take beta-blockers (like propranolol) to lower heart rate
4. If there is a blood pressure drop, which as we noted this wouldn’t be true POTS then individuals are given a medication to increase blood pressure.
5. Cardiology and neurology often try to work together to send the individual to do physical therapy with a focus on building back up strength and endurance.

While these can help some symptoms, they fail to address the root cause. Many patients feel frustrated when medications like propranolol leave them with brain fog and fatigue but don’t actually fix what’s causing their POTS in the first place.

Physical therapy in our experience often makes these individuals worse as it’s not done at the right time. It’s not as simple as just building up physical endurance, you must identify what is driving the POTS to begin with. After that is treated then physical therapy or simply going to a gym and working up can go well.

A Smarter Approach to Treating POTS

To understand what to look for in treatment it’s important to understand that even though it’s often treated as a cardiovascular condition; it’s not for many. It is a neurological and immune based issue that manifests with a variety of symptoms with the hallmark feature being heart rate.

To truly improve, you need a comprehensive plan that evaluates:

1. Neurological function – Brain imbalances can lead to autonomic dysfunction. Testing eye movements and balance can provide crucial insights into nervous system health.
2. Immune system health – Autoimmune issues and chronic inflammation are major drivers of POTS.
3. Gut health – IBS and leaky gut can worsen POTS symptoms due to their connection with the nervous and immune systems.
4. Mast cell activation & histamine response – Many POTS patients also experience extreme reactions to foods, environmental triggers, and stress.
5. Hormonal balance – Menstrual cycles, adrenal dysfunction, and thyroid disorders all influence POTS symptoms.

We will briefly discuss how to evaluate the nervous and immune system in pots and dysautonomia.

Many people will naturally think they need a MRI or a CT scan due to the headaches, dizziness, and nausea. They are routinely disappointed if they do get one as this does not provide any information for someone with POTS and chronic fatigue. It should be done if there is worry of something like a tumor or brain bleed. It is essential to look at nervous system function.

The eyes are known as the windows into the health of the brain. A comprehensive eye movement assessment should be done using computerized technology known as videooculography. This allows for the highest level of evaluation and is very educational as it allows you to see where you did well and did not. Components of an eye movement examination should include: vergence, fixation, pursuits, saccades, and optokinetics.

The other side of the neurological evaluation is balance. Balance testing is routinely off with many POTS patients. What we’ve found is if it’s only balance then it’s not necessarily something that is treated. If both eye movements and balance are off then neurological rehab does really well. You may be wondering why it’s not necessarily appropriate to treat poor balance. As you’ve experienced, you notice fatigue, weakness, and inability to be on your feet too long. When balance is off it could be due to neurological dysfunction or simply related to the fatigue and weakness many have.

The immune system is initially evaluated by looking at triggers that impact symptoms. What happens when you get stressed, sick, menses, food choices, or sleep changes. Based on this it gives the provider a good idea of where to start. Beyond this it is often beneficial to evaluate immune system markers, gut health, and reactions to mycotoxins from molds.

How We Help People with POTS Recover and Feel Better

At Peak Brain and Body, we take a root-cause approach to POTS and chronic fatigue treatment, using advanced neurological testing, brain function assessments, immune system evaluations, and metabolic panels to uncover hidden triggers. This isn’t just another evaluation or brief visit, this is the most in-depth evaluation most of our patients have ever had.

Here’s what makes our approach different:

• We connect the dots between your brain, nervous system, and immune function.
• We perform in-depth testing beyond standard labs to find hidden infections, gut imbalances, or underlying concussions that may be contributing to your symptoms.
• We use targeted therapies like eye movement therapy, balance retraining, cognitive therapy, low level laser, hyperbaric oxygen therapy, and functional medicine interventions to restore nervous system balance.

Based on your testing a customized care plan is created. It’s not just about finding out what is wrong, but knowing the order things should be addressed.

The Path to Healing From Pots and Dysautonomia

Healing from POTS isn’t about finding a magic pill—it’s about finding the right roadmap for your unique body. While no two POTS cases are identical, addressing neurological health, immune balance, and gut function can make a world of difference.

If you’re tired of bouncing from doctor to doctor without answers, it’s time for a different approach. You deserve to work with someone who understands the bigger picture and has the tools to help you get your life back.

At the end of the day, knowledge is power. You don’t have to live with POTS controlling your life. With the right approach individuals routinely find healing is possible even if they’ve been told nothing else can be done.

Brain Fog Treatment | Peak Brain and Body | Tampa and Wesley Chapel, FL.

Finding the right brain fog treatment is often frustrating. If you go to a doctor and complain of brain fog, they’ll often tell you it’s not a big deal, labs are normal, or it’s related to mental health. But, is that really all there is when it comes to brain fog? First, let’s establish some basics. 

When you hear the term brain fog, what do you think of?

• Your brain is running slow and feel like you are in a haze.
• When having conversations with friends and co-workers you seem to struggle to find the word even though it is right at the tip of your tongue.
• Maybe you just feel off and not yourself.
• You catch yourself walking into the kitchen to grab something but when you get there you forget why you went in there to start.

If so, you might be experiencing brain fog, which is a term that refers to the inability to think clearly or you just feel off.

It may persist days, months, or even years until the underlying cause has been identified. Some of these causes occur in an instant, but others you may not think of. Before we dive into what can cause brain fog, I want you to think of brain fog as inflammation, impaired connections or reduced oxygen in the brain impacting function.

HERE ARE FIVE REASONS WHY YOU ARE SUFFERING FROM BRAIN FOG

1. FOOD INTAKE

Have you ever noticed feeling tired and unable to think after eating a meal that contains gluten or dairy? Or You sit down to enjoy a big chicken sandwich and fries at lunch to only want to take a nap 30 minutes later as your brain starts shutting down.

This occurs because eating certain foods creates inflammation. Inflammatory foods lack nutrients we need to be healthy but also may block the absorption of nutrients that your brain needs to function at its best.

Research shows that lack of the following nutrients may result in brain fog : 1

• Omega 3 fatty acids (DHA)
• Flavonoids
• Curcumin
• B vitamins
• Vitamin D
• Choline
• Vitamins A, C, and E
• Zinc
• Selenium
• Copper
• Iron
• Magnesium

While saturated fat has been shown to promote cognitive decline, omega 3 fatty acids help prevent it. So, try eating more fish and less processed red meat.

Here are some other foods to add to your diet to reduce brain fog:

• Fatty fish
• Flax seeds
• Krill
• Chia seeds
• Walnuts
• Unprocessed cocoa
• Green tea
• Kiwi
• Avocado
• Asparagus
• Mushrooms
• Green, leafy vegetables
• Citrus fruits
• Oysters

2. GUT INFLAMMATION.

Is your brain fog accompanied by digestive problems like constipation, bloating, diarrhea, or gas? How about dry skin, bad breath, acne, and weight gain around your waist and hips?

If so, that’s a sign of gut inflammation and it’s likely the reason why you are unable to think after eating certain inflammatory foods, such as crackers, pasta, or cheese.

So, why and how does this happen?

It’s because your gut and brain are connected by the vagus nerve, which runs from your brain to the stomach. It brings information to your stomach, but also brings information back to the brain.

When you eat inflammatory foods (gluten, dairy, refined sugars, processed grains, or candy), it causes your gut to send “distress” signals to your brain, affecting your thought process.

However, when your gut is healthy and working properly, it allows you to think more clearly and have better memory recall by properly stimulating the vagus nerve.

Additionally, your gut produces many hormones and neurotransmitters that control weight, appetite, and mood.

• 85% of serotonin is produced in the gut and is important for happiness
• Dopamine is responsible for reward and motivation

Here’s how to restore gut health:

• Eliminate refined sugars and processed foods from your diet (pretzels, crackers candy, soda, packaged snacks, and bread)
• Avoid gluten, dairy, refined sugars, and grains
• Supplement with probiotics
• Eat more fresh fruits and vegetables
• Focus on eating minimally processed foods
• Get regular exercise
• Focus on getting eight hours of sleep each night

3. STRESS

Has a highly stressful conversation with someone immediately made you feel like you forgot how to speak mid-conversation? That’s stress.

Maybe the stress carries with you the rest of the day and you develop a headache, dizziness, or poor concentration.

Research shows that high cortisol, stress chemical, levels shrink parts of the brain that are responsible for learning and memory . It’s also linked to premature brain aging. 2

Having a healthy outlet for stress is important for proper brain function. The old mindset of grin and bear it is detrimental to our brain health.

Here are some ways help with stress and bring down cortisol levels:

• Exercise regularly
• Practice breathing exercises
• Try yoga or meditation
• Focus on improving your quality of sleep
• Eat an anti-inflammatory diet
• Avoid refined sugar and processed foods
• Use your vacation days

4. INSUFFICIENT QUANTITY OR QUALITY OF SLEEP

Do you feel like you can’t think at all in the morning after a restless night of sleep? Do you find that easy tasks like getting your kid’s backpack ready is impossible?

Maybe when you try to go sleep your mind starts racing and you need Benadryl or melatonin to fall asleep an hour or two later.

Sleep is essential for brain function. During sleep, your brain “cleans” itself by removing toxins and waste that negatively impact cognitive function and help make morning tasks easier. If you don’t sleep this is like the garbage truck not showing up and no one wants that.

Here are some tips for getting better sleep:

• Set a bedtime routine
• Sun exposure
• Go to bed and wake up at the same time daily
• Reduce exposure to light before bed
• Keep your room cool and dark
• Eat a light dinner based around fats and proteins with low carbs
• Avoid drinking too close to bedtime
• Limit screen time
• Blue light filter

5. CONCUSSION

You may think a concussion isn’t a big deal, but did you know that 50 percent of people who suffer a concussion have brain fog years later, even if you don’t have it right away ? 3

A concussion is the most common form of traumatic brain injury. Unfortunately many suffer a concussion but never receive a proper diagnosis or do not know that it can impact them years later.

You can suffer a concussion without hitting your head even from a rapid movement of your head forward and back. Common causes of concussion are car accidents, sports injuries, slips and falls, and blows to the head.

Although the incident might not seem a big deal at the time, some research suggests that nearly 50% will have long-lasting symptoms due to inflammatory changes that occurred when you became injured. 4

Symptoms of a concussion impact cognition, physical, and emotions:

• Feeling like you’re moving slowly
• Difficulty concentrating and remembering things
• Inability to focus
• Frequent headaches
• Sensitivity to light and noise
• Sleep disturbances
• Balance problems
• Fatigue
• Vision changes, fuzzy or blurry vision
• Anxiety or mood fluctuations

LAST THOUGHTS

So what exactly is brain fog, well it is a description that individuals use when their brain isn’t processing correctly or they are in a haze. At a cellular level this can occur due to inflammation, reduced oxygen, or impaired connections in the brain.

There are many causes of brain fog and we didn’t even cover them all. For beginners, don’t look past the role of nutrition, gut health, stress, sleep, and concussions as contributing factors to brain fog.

It is okay, you are likely overwhelmed at the thought of how many different things may contribute to your brain fog and would like expert help.

You may be wondering how we evaluate and address the cause of your brain fog. We utilize The BMB Method (Brain, Mind, & Body) that has been refined over the past 9 years. This allows us to look where others aren’t, as well as view each person as an individual by:

• Evaluating the brain looking at function using eye movements, balance, and brain waves.
• Evaluating the mind reviewing past traumas and the subconscious programming that prevents you from success in life.
• Identifying how the different systems in the body are functioning using symptoms and lab testing.

By using The BMB Method we are able to provide answers and solutions when other programs have failed. If you are ready to try a new approach to these symptoms that are robbing you of your life then request your health strategy session today.
