What Does a Functional Neurologist Actually Do?

The Gap Between "Normal" and "Well"

Conventional medicine is extraordinarily good at detecting structural disease. MRI can identify a tumour to the millimetre. Blood panels can flag autoimmune markers. Nerve conduction studies can pinpoint a damaged nerve. These tools are essential — and when they find something, the pathway forward is usually clear.

But there is a large population of people for whom every test comes back normal, and yet they are clearly not well. Chronic fatigue that does not improve with rest. Neurological symptoms — tremors, weakness, altered sensation — with no structural explanation. Dysautonomia that leaves them unable to stand without their heart rate spiking. Post-concussion symptoms that persist months or years after the initial injury. Anxiety that does not respond to therapy or medication.

This is the gap that functional neurology was built to address. Not the absence of disease — but the presence of dysfunction. The nervous system is clearly not working properly, even when it looks structurally intact on imaging.

Where Does Functional Neurology Come From?

Functional neurology is a broad and evolving field, and it is worth being transparent about its origins — because they explain both its strengths and the diversity of approaches you will encounter under that label.

The field was largely formalised by Professor Frederick (Ted) Carrick, a chiropractor and neurologist who developed a systematic framework for applying neuroplasticity principles to clinical practice. Carrick's work — particularly his development of the Carrick Institute — established the idea that the nervous system could be assessed and rehabilitated through targeted afferent stimulation, even in the absence of structural pathology. His influence on the field has been significant, and many practitioners worldwide trace their training lineage back to his work.

Alongside this, functional neurology has deep roots in Applied Kinesiology (AK) — a system developed by Dr George Goodheart in the 1960s that uses muscle testing as a diagnostic and therapeutic tool to assess neurological function. AK introduced the idea that the body's muscular responses could provide a window into nervous system status, and that specific interventions — nutritional, structural, and neurological — could restore function. It remains a controversial area within mainstream medicine, but its clinical insights into the relationship between muscle function and neurological organisation have been influential.

At Functional Neuro Health, the approach sits at the intersection of both traditions — and goes beyond either alone. What we do is apply the assessment and organisational principles of Applied Kinesiology with the depth of Functional Neurological understanding. AK provides a precise, body-based language for identifying which neurological pathways are dysregulated. Functional neurology provides the anatomical and physiological framework for understanding why — and for designing a sequenced rehabilitation programme that addresses the root cause rather than the symptom.

This synthesis is not common. Most practitioners trained in functional neurology do not have a deep grounding in AK, and most AK practitioners do not have the neurological framework to contextualise what the body is communicating. The FNH approach brings both together — which is why the clinical outcomes tend to be more precise and more durable than either approach in isolation.

Functional Neurology vs Conventional Neurology

The distinction is not about one being better than the other — they address different problems. Conventional neurology is the right choice when structural disease is suspected. Functional neurology becomes relevant when the nervous system is clearly dysregulated but no structural lesion explains it.

What a Functional Neurological Assessment Involves

The first session at Functional Neuro Health is a detailed clinical assessment — not a conversation about symptoms, but a systematic examination of how the nervous system is actually performing. This typically takes 60–90 minutes and covers several domains.

The output of this assessment is not a diagnosis in the conventional sense — it is a functional map. Which pathways are underperforming? What is the likely neurological driver of the symptoms? What is the correct sequence of intervention? This map becomes the basis for every subsequent session.

Conditions Commonly Addressed in Melbourne

The clients I work with in Melbourne — and online — typically share one thing in common: they have been through the conventional medical system, received normal or inconclusive results, and are still significantly unwell. The conditions that respond well to functional neurology include:

• Functional Neurological Disorder (FND) — Neurological symptoms — tremors, non-epileptic seizures, weakness, altered gait — without structural lesion. FND is a disorder of nervous system function, not structure, which makes it precisely suited to functional neurological rehabilitation.
• Dysautonomia and POTS — Dysregulation of the autonomic nervous system producing orthostatic intolerance, heart rate instability, fatigue, brain fog, and digestive dysfunction. The autonomic nervous system is directly addressable through functional neurology.
• Post-Concussion Syndrome — Persistent symptoms following head injury — headache, cognitive fog, light and noise sensitivity, sleep disruption, emotional dysregulation — that continue beyond the expected recovery window. Functional neurology addresses the specific neural circuits disrupted by the impact.
• Chronic Pain and Central Sensitisation — Pain that persists after tissue healing, or pain that is disproportionate to the apparent injury. Central sensitisation — where the nervous system itself becomes the amplifier — is a neurological problem requiring a neurological solution.
• Complex Anxiety and Nervous System Dysregulation — Anxiety that does not respond to standard psychological approaches often has a neurological substrate — low vagal tone, retained primitive reflexes, or cerebellar dysregulation that keeps the threat-response system chronically activated.
• Retained Primitive Reflexes in Adults — Primitive reflexes that failed to integrate in childhood can drive sensory processing difficulties, attention problems, emotional dysregulation, and postural instability in adults — often without any awareness of the underlying mechanism.

The PEACE Method: A Sequenced Approach

One of the things that distinguishes the approach at Functional Neuro Health from general nervous system work is the use of a structured clinical framework — the PEACE Method. PEACE is an acronym for the five domains addressed in sequence: Primitive reflexes, Emotional regulation, Autonomic balance, Cerebellar function, and Efferent output.

The sequencing matters. Attempting to address higher-order function — emotional regulation, cognitive performance, complex motor patterns — before the foundational layers are stable is inefficient at best and counterproductive at worst. The nervous system has a hierarchy, and effective rehabilitation respects it.

This is what separates a structured functional neurological approach from general wellness work. It is not a collection of techniques applied to symptoms. It is a systematic, hierarchical rehabilitation of the nervous system from the ground up.

Is Functional Neurology Evidence-Based?

This is a fair question, and it deserves a direct answer. The core principles underlying functional neurology — neuroplasticity, afferent-based rehabilitation, the role of the cerebellum and vestibular system in chronic conditions, the autonomic nervous system's relationship to chronic pain and fatigue — are well-supported in peer-reviewed neuroscience literature.

What is less established is the specific clinical application of these principles to the range of conditions functional neurologists work with. The evidence base is growing, but it is not yet as robust as the evidence for, say, pharmacological treatment of epilepsy. This is partly a function of funding — neuroplasticity-based rehabilitation does not have a pharmaceutical sponsor — and partly a function of the complexity of measuring functional outcomes in heterogeneous populations.

My position is this: the underlying neuroscience is solid. The clinical reasoning is grounded in published research. And the outcomes I see in practice — across 17 years and more than 10,000 clinical hours — are consistent with what the science would predict. I am not asking clients to take anything on faith. I am asking them to engage with a rigorous, systematic examination of how their nervous system is functioning, and to follow the evidence where it leads.

What to Expect in Melbourne — and Online

Functional Neuro Health operates from Melbourne and online. The initial assessment is available in person, and many clients — particularly those with post-concussion syndrome, dysautonomia, or fatigue-based conditions — find that online sessions are not only accessible but effective, because a significant portion of the functional neurological work involves guided self-regulation protocols rather than hands-on treatment.

Initial consultations are 60–90 minutes. Follow-up sessions are typically 45–60 minutes. The frequency and total number of sessions depends on the complexity of the presentation, but most clients have a clear sense of whether the approach is working within the first three to four sessions.

If you have been through the conventional medical system without resolution, and you are looking for a clinician who will take the neurology seriously rather than defaulting to symptom management, a functional neurological assessment is a logical next step.
