Neuro Unfiltered is the podcast for the patient who has done everything right, seen the specialists, had the scans, followed the protocol, and still doesn't have answers. Dr. Michael Longyear is a chiropractor, functional neurologist, co-founder of the Brain Optimization Institute, and an international educator training physicians around the world. After years in clinical practice, he kept hearing the same questions from patients and their families. Questions conventional medicine either didn't have time for or didn't know how to answer.
EP13: Psilocybin, DMT, and the Brain's Filter: How They Work and Why Researchers Are Paying Attention
In this episode of Neuro Unfiltered, Dr. Michael Longyear answers the question he heard more than any other this past weekend: what are psilocybin and DMT actually doing in the brain? To be clear from the start, this episode is education, not endorsement. Dr. Longyear does not condone, recommend, or promote the use of psilocybin, DMT, or any psychedelic. This is a look at the science, and nothing more.
How do these compounds, built on the same chemical backbone as serotonin and melatonin, interact with the brain's own receptors? What happens downstream to glutamate, the brain's accelerator, and GABA, the brain's brakes? And why is an idea from the 1950s, that the brain filters out most of what comes in and that these compounds may loosen that filter, now getting a second look with modern brain imaging and research into neuroplasticity?
If you have seen these compounds in the headlines and want to understand the neuroscience without the hype or the fear, this episode explains what the research actually says and how early that evidence still is.
Psilocybin and DMT are controlled substances in most of the U.S., including Florida. Nothing in this episode is medical advice. These compounds carry real psychiatric and cardiovascular risks and interact with common medications, including antidepressants. Talk to your physician before making any decision about your health.

EP12: Post-Concussion Syndrome — Why You Haven't Recovered and What to Do Next
In this episode of Neuro Unfiltered, Dr. Michael Longyear confronts one of the most undertreated conditions he sees in clinical practice. Post-concussion syndrome. And why the standard protocol of rest, darkness, and time is failing the patients who need active intervention most.
What is actually keeping a concussion patient stuck months or years after the initial injury? Why do cervicogenic dysfunction, vestibulo-ocular deficits, and autonomic dysregulation so consistently go unidentified in standard post-concussion care? And what does a functional neurological evaluation reveal about incomplete recovery that a standard follow-up appointment never will?
If you have been told you just need more time and your symptoms are still not resolving, this episode explains what the research actually says about why and what comes next.

EP11: POTS and Dysautonomia — Can I Exercise, Should I Exercise, and How Do I Know When I've Done Too Much
In this episode of Neuro Unfiltered, Dr. Michael Longyear addresses one of the most contested and confusing questions in the dysautonomia community. Whether exercise is safe, beneficial, or dangerous for patients living with POTS and autonomic dysfunction.
Why does the standard medical advice of either complete rest or pushing through consistently fail this patient population? What is actually happening in the autonomic nervous system during physical exertion and why does the wrong type of exercise at the wrong intensity make dysautonomia worse rather than better? And what does a safe, progressive, neurologically informed approach to movement actually look like for someone whose nervous system doesn't regulate the way it should?
For every POTS patient who has been given conflicting advice and no clear path forward, this episode is the conversation you have been waiting to have.

EP10: When Anxiety Doesn't Respond to Treatment: What They Missed
In this episode of Neuro Unfiltered, Dr. Michael Longyear examines a reality that millions of patients live with but rarely hear explained. Anxiety that doesn't respond to therapy or medication may not be a psychological problem at all. It may be an unidentified neurological one.
What is the relationship between the vestibular system and anxiety and why does vestibular dysfunction so consistently produce symptoms that look identical to panic and generalized anxiety disorder? How does cerebellar dysfunction contribute to a nervous system that cannot regulate itself? And why are so many patients cycling through therapists and psychiatrists when the answer may lie in a neurological evaluation they have never been offered?
If treatment hasn't worked and nobody has looked at your brain, this episode asks the question your care team may have missed.

EP9: Brain Fog Is Not Depression: What's Actually Happening Inside Your Head
In this episode of Neuro Unfiltered, Dr. Michael Longyear tackles one of the most dismissed and misdiagnosed symptoms in modern neurology. Brain fog. And why treating it as a mood disorder is one of the most common and costly mistakes in conventional medicine.
What is actually happening inside the brain when a patient describes feeling like they are underwater, thinking through mud, or struggling to find words they have known their entire life? Why do so many brain fog patients get handed an antidepressant when the real driver is neurological? And what does the emerging science on neuroinflammation tell us about how to actually address the root cause?
If you have been told your brain fog is stress, depression, or something you just need to manage, this episode offers a very different explanation.

EP8: You Are Not Your Diagnosis: What Makes Me Angry in Health Care
In this episode of Neuro Unfiltered, Dr. Michael Longyear names the thing in health care that angers him most: clinicians who place limits on their patients, and the way a diagnosis can quietly become a ceiling rather than a starting point.
Why do so many patients accept a prognosis as a fact about their future rather than a prediction someone made? What happens when a label stops describing a condition and starts describing a person? And how many diagnoses are actually explanations, versus the patient's own words handed back to them in Latin?
This episode is for every patient who was told this is as good as it gets, every person who has started introducing themselves by their diagnosis, and everyone who has ever wondered whether the limit they were given was real or simply the edge of what one clinician knew.

EP7: Your Labs Came Back Normal: So Why Do You Still Feel Like This?
In this episode of Neuro Unfiltered, Dr. Michael Longyear breaks down what lab work actually tells you, why standard panels are built to catch disease rather than dysfunction, and why so many patients are handed normal results while their symptoms go unexplained.
What is a routine annual panel actually designed to detect, and what falls outside its reach? Why can the same blood produce an in-range result at one lab and an out-of-range result at another? And when a doctor says everything looks fine but nothing feels fine, what is the next question a patient should be asking?
This episode is for every patient carrying a folder of normal results with no explanation, every person who has been told their labs are unremarkable while their life is anything but, and every patient who suspects the right test was never ordered in the first place.

EP6: Getting Off Antidepressants: What the Conversation With Your Doctor Should Actually Include
In this episode of Neuro Unfiltered, Dr. Michael Longyear addresses one of the most requested and most avoided conversations in his practice. What it actually looks like to safely and thoughtfully taper off antidepressant medication with proper neurological support.
Please note: nothing in this episode is medical advice and Dr. Longyear is not recommending that anyone stop their medication. Always consult the physician who prescribed your medication before making any changes.
What does the brain actually go through during antidepressant discontinuation and why do so many patients experience severe withdrawal symptoms that their prescribing doctor never warned them about? What does a supported, neurologically informed taper look like compared to stopping abruptly or reducing too quickly? And what questions should every patient be asking before, during, and after the process? Questions that most 15-minute appointments never get to.
This is the conversation your prescriber may not have had time to have with you.

E5: Your DNA Is Not Your Destiny: Genetics, Genomics, and Epigenetics Explained
In this episode of Neuro Unfiltered, Dr. Michael Longyear explores one of the most empowering and most misunderstood concepts in modern neuroscience. The idea that the genes you were born with do not determine the neurological future you will have.
What is the actual difference between your genetic code and your gene expression and why does that distinction change everything? How do environment, lifestyle, stress, and sleep literally talk to your DNA in ways that can accelerate or protect against neurological disease? And what does epigenetics mean for the patient who has been told their condition is simply genetic and therefore fixed?
The science of epigenetics puts more control back in your hands than most doctors will ever tell you. This episode explains exactly how.

EP4:Trust Your Mom Gut: Why Mothers Are the Best Functional Neurologists in the Room
In this episode of Neuro Unfiltered, Dr. Michael Longyear makes the case that mothers are among the most accurate early detection systems in neurological care and that the medical system is failing them by not listening.
Why do mothers consistently identify that something is wrong before any clinician does? What do natural observation settings reveal about neurological function that a 20-minute clinical appointment never could? And when a mother's instinct conflicts with a doctor's assessment, who should she trust and what should she do next?
This episode is for every mother who has been told she is overreacting, every caregiver who was dismissed before they could finish a sentence, and every parent who walked out of an appointment knowing the answer they received wasn't the right one.

EP3: What Is Functional Neurology: Why Your Neurologist Doesn't Do It
In this episode of Neuro Unfiltered, Dr. Michael Longyear breaks down one of the most misunderstood distinctions in modern medicine. The difference between conventional neurology and functional neurology, and why that difference could change everything for patients who have run out of answers.
Why do so many people with debilitating neurological symptoms get told their tests are normal? What is conventional medicine actually designed to find and what does it consistently miss? And what does it mean to evaluate the brain not just for disease, but for dysfunction?
If you have ever walked out of a neurologist's office with a clean MRI and no explanation for what you are experiencing, this episode was built for you.

E2: Can I Get Better? The Question Every Patient Is Afraid to Ask Out Loud
In this episode of Neuro Unfiltered, Dr. Michael Longyear answers the question that sits behind every first appointment, every second opinion, and every sleepless night spent searching for answers. Can I actually get better?
What does neuroplasticity really mean when you take it out of the self-help world and put it into a clinical setting? What separates the patients who recover from the ones who stay stuck? And what does the science actually say about the brain's capacity to reorganize, adapt, and heal even after years of dysfunction?
This isn't false hope. This is the honest, science-backed answer to the question most doctors don't have time to fully address.

E1: From Paralysis to Doctor: Why I Do What I Do
In this episode of Neuro Unfiltered, Dr. Michael Longyear takes you back to the moment that changed everything. Waking up at 15 years old unable to move his legs, facing a medical system that had no answers, and walking out of a hospital with a missed diagnosis and a decision that would define the rest of his life.
What does it feel like to experience a neurological event that nobody can explain? What happens to a patient and a future doctor when the system designed to help them fails completely? And how does that experience shape the way a clinician shows up for the patients who have been dismissed, misdiagnosed, and told to simply learn to live with it?
This is the story behind Brain Optimization Institute, behind Neuro Unfiltered, and behind a career dedicated to finding what others miss. If you have ever felt like medicine gave up on you, this episode is where we start.
