Still dizzy, foggy, exhausted—or dealing with racing heart symptoms—despite “normal” tests?

In this Q&A episode, Dr. Zimmerman explains why concussions and POTS are often misunderstood, why MRI/CT scans are usually normal in concussion, and what most evaluations miss (objective balance + eye-movement testing). He also breaks down POTS as a nervous system/autonomic issue, why patients get bounced between cardiology and neurology, and how immune/metabolic factors like histamine patterns and low ferritin can worsen symptoms.

A concussion story most people never hear. Dr. Zimmerman and his wife, Sara, share the raw, real experience of navigating yet another concussion—from subtle early symptoms to the emotional toll it takes on daily life.

When symptoms don’t make sense—but your body knows something is wrong. Fatigue, mood swings, dizziness, nausea, memory lapses, and loss of motivation all appeared quickly, even after what seemed like a minor hit.

Why standard care often leaves people stuck. Learn how normal scans, generic treatments, and symptom-chasing can miss the true neurological drivers of post-concussion symptoms.

What actually made the difference this time. From vestibular and eye movement findings to targeted neurological therapies, hear how a personalized approach helped symptoms improve faster than expected.

A powerful reminder for anyone who’s been told “this is just how it is.” This episode challenges the belief that chronic concussion symptoms are permanent—and explains why the right care matters more than ever.

• What if a little-known brain fat could play a major role in fatigue, brain fog, and neurodegeneration? Dr. Zimmerman introduces plasmalogens and why they’ve become a key focus in complex neurological cases.
• Plasmalogens quietly protect brain, nerve, and heart cells—until levels drop. Learn how aging, inflammation, and chronic conditions may accelerate their loss and what that means for symptoms and disease progression.
• Emerging research links low plasmalogens to conditions like Parkinson’s, Alzheimer’s, MS, and neuropathy. This episode explores what the science suggests—and why waiting years for “perfect data” isn’t an option for those suffering now.
• Why supplementation isn’t as simple as “take more.” Dr. Zimmerman breaks down absorption challenges, precursor strategies, and why dosing must be individualized.
• Plasmalogens aren’t a magic bullet—but when stacked with the right neurological and immune support, they may change the trajectory. Discover how they fit into a true brain-body, systems-based approach.

This episode is a must-listen if you’ve tried “everything” and are still searching for answers that actually move the needle.

Myth #1: “It’s just anxiety.” Dr. Z breaks down why this misunderstanding leads to misdiagnosis, gaslighting, and years of unnecessary suffering.

Why drinking more water and pounding salt isn’t a real solution—and what’s actually driving your dizziness, fatigue, and tachycardia.

The shocking truth: Most POTS symptoms are neurological, not cardiovascular—and traditional testing completely misses it.

Why medications help some symptoms but never fix the root problem (and why you crash as soon as you stop them).

The biggest unlock: Your visual system, vestibular system, hormones, blood sugar, and immune health may be the hidden drivers your providers never checked.

If you’re dizzy, exhausted, lightheaded, and constantly brushed off by traditional medicine, this episode will feel like someone is finally connecting the dots.

What you’ll learn:

• Why “normal” labs don’t mean anything is actually normal for POTS patients—and why most people are told everything looks fine when they clearly don’t feel fine.
• The big flaw in the traditional POTS approach: it manages symptoms but ignores the nervous system dysfunction driving them.
• **The hidden neurological issues no one checks—**like eye-tracking and vestibular reflexes—that keep 75–80% of POTS patients dizzy, anxious, and fatigued.
• How advanced testing at Peak Brain & Body uncovers what cardiology and neurology miss, leading to real, lasting improvement.
• Why POTS is never “one thing,” and why treating the whole system (hormones, immune function, infections, mold, anemia, etc.) finally moves the needle.

In this episode I take questions from the audience and review the research on a variety of topics.

The concussion we all missed: Using Mike Evans’ hit as a case study, Dr. Z shows why a “minor” concussion can be far more life-altering than a broken collarbone—and how symptoms get rationalized away.

Depression redefined: New findings on excitatory neurons and microglia link mood and inflammation—explaining why exercise, vitamin D, gut health, and targeted nutrition help some people more than meds alone.

Women’s brain health & hormones: How menopause accelerates brain atrophy in MS, which regions are hit (memory, attention, emotion), and why LC/MS hormone testing changes the conversation on safe HRT.

Parkinson’s is rising—here’s why: Environmental exposures (industrial degreasers, pesticides, head trauma, autoimmunity) drive risk—and the practical levers you can control now.

From POTS to “wear-and-tear” knees: Why POTS is a neuro-immune problem (not a single-cause diagnosis), how ultra-processed foods speed cartilage loss, and what emerging evidence says about Boswellia + celery seed for pain, function, and inflammation.

Chemo brain, demystified: How mitochondrial stress and systemic inflammation drive brain fog, memory lapses, and slowed thinking—and what helps.

Food as a therapeutic tool: A simplified, modified Mediterranean approach (gluten-free, low-sugar, organic) to lower inflammation and feed the brain.

Support during treatment: Why timing matters for intermittent fasting, what to avoid during radiation, and where melatonin and select botanicals may fit.

Cachexia vs. “just eat anything”: Calorie-dense, therapeutic smoothies as a smarter alternative to ultra-processed shakes when appetite is low.

Home detox made doable: High-impact swaps (fragrance plugins, dryer sheets, plastic foodware, bottled water, microwaving in plastic) to cut hormone disruptors.

Stronger bones on AIs/Tamoxifen: The right form of calcium plus D3, K2, collagen precursors—and bone-loading movement—to reduce osteoporosis risk.

Mindset & the “cancer train”: How to pause urgency, build a healing team, and use breathwork, meditation, acupuncture, and graded exercise to steady emotions.

HRT after breast cancer—handle with care: Why this decision must be personalized (oncology, BHRT specialist, Dutch testing, vascular screening, tight lab follow-up).

Neuroplasticity—your brain’s ability to adapt—can work for or against you. In this episode, I explain what it really is, why most providers overlook it, and how to harness it for recovery. From concussion and POTS to migraines, brain fog, and mood issues, I cover how precise testing and targeted therapies can rewire the brain, restore energy, and improve resilience.

In this episode:

• Neuroplasticity, simplified: the brain’s ability to change—sometimes helpful, sometimes harmful—depending on how it’s directed.
• How to measure brain function: neurological exams, balance and eye-movement testing, cognitive testing, and QEEG go beyond standard scans.
• Why generic rehab fails: overdoing or under-dosing therapy stalls progress; success depends on the right dose at the right time.
• Conditions helped by plasticity:
  • Concussions/PCS—rest alone doesn’t heal, but targeted vestibular, visual, and autonomic rehab does.
  • POTS/Dysautonomia—rewiring balance and eye-movement systems improves symptoms.
  • Migraines—strengthening brain circuits raises resilience and reduces attacks.
  • Chronic fatigue, brain fog, mood issues—often tied to inefficient or inflamed brain pathways.
• Tools that drive change: vestibular & vision rehab, cognitive training, neurofeedback, TMS, exercise, nutrition, sleep, and stress control.
• Proof in practice: Sara’s recovery shows the brain can change—even after years of symptoms.

Takeaway

Most brains can change when assessed precisely and treated specifically. Neuroplasticity isn’t a buzzword—it’s the most underused path to healing.
