Reconnecting Mind and Body

FND is a complex neurological condition with symptoms unexplained by imaging, often including non-epileptic seizures. We offer a careful, evidence-based clinical approach and have experience supporting patients with significant improvement.

Understanding FND

Functional Neurological Disorder (FND)

A careful, physiology-informed approach to a complex conditio

Functional Neurological Disorder (FND) is a real, debilitating condition that occurs when the brain’s functional pathways are disrupted despite normal structural scans. Patients may experience a wide range of neurological symptoms, including episodes that resemble seizures, weakness, tremors, sensory disturbances, gait problems or dissociative events.

FND can be frightening and life-altering, especially when patients are told, “Your scan is normal, so nothing is wrong.” Normal imaging does not mean the symptoms are imagined. It means the cause lies in the function of the system rather than its structure.

Identifying the Root Cause

Our Clinical Approach: Evidence-Backed, Mechanism-Focused

The NICE position on FND is clear: FND is a positive diagnosis, not a diagnosis of exclusion.

However, in practice many patients with FND-like symptoms also have treatable medical contributors that can worsen or mimic functional symptoms. These are often overlooked in routine workups.

We assess patients with FND-type presentations using a careful, physiology-based framework, which may include

Detailed neurological history
Assessment of autonomic symptoms
Review of precipitating stressors or triggers
Evaluation for sleep disorders
Targeted blood tests where clinically indicated
Review of metabolic factors that can influence nerve and brain function

The goal is

Understand the pattern
Identify treatable contributors
Improve symptoms
Restore function
Provide a clear explanation and plan

Understanding How Metabolic Health Can Influence Neurological Symptoms

Metabolic Factors and FND Symptom

Many patients with FND-like symptoms also report:

Sensory disturbances
Weakness or collapses
Dissociative episodes
Tremors or internal shaking/vibrations
Cognitive fog
Fatigue
Temperature or autonomic instability

Some of these symptoms can overlap with those seen in vitamin deficiencies (such as B12, D or iron) or other metabolic issues.

We do not claim these deficiencies cause FND. But we do recognise that metabolic issues can exacerbate symptoms or create parallel neurological disturbances that complicate the picture.

Our role is to identify and treat what is treatable. This aligns with both clinical reasoning and patient safety.

Experience-Informed Care Supported by Ongoing Observation

Clinical Experience & Ongoing Case Work

We have cared for several patients with FND-type presentations who improved significantly after a combination of:

Careful neurological assessment
Metabolic optimisation
Structured follow-up
Tailored symptom-management strategies

Some cases have shown notable improvement after treating deficiencies such as B12, vitamin D or iron — particularly where symptoms overlapped with metabolic or autonomic dysfunction.

We are currently developing case studies and observational reports in this area, with the intention of contributing to the broader clinical understanding of FND.

This research-engaged approach ensures we practise responsibly, transparently, and with academic credibility.

Compassionate, Evidence-Based Care You Can Trust

What You Can Expect From Us

1. A respectful, validating approach
Your symptoms are real and not dismissed as “psychological”.

2. A careful neurological and systemic review
We examine symptoms, timelines, triggers and patterns.

3. Investigation of treatable contributors
Where clinically appropriate.

4. Supportive management plan
Covering movement, pacing, metabolic health, sleep, stress physiology, and functional neurology principles.

5. Honest communication about prognosis
FND recovery is variable. Many improve significantly. Some improve partially and recovery may take some time. A cautious but hopeful prognosis is always safest and most accurate.

6. Ongoing follow-up and monitoring
We do not discharge you after a single consultation.

Thoughtful, Evidence-Based Care for Complex Presentations

Why Patients Choose Rubicon Private Health for FND-Like Symptoms

A GP with deep experience in complex neurological presentations
Non-judgemental, thorough care
Longer appointments
Clinical curiosity rather than dismissal
Recognition of metabolic contributors that are often overlooked
A research-engaged, evolving approach
Clear communication + logical explanations

Many patients come to us after years of feeling unheard. We aim to change that experience.
