Presentation & Background

A 30-year-old male countryside ranger presented with persistent brain fog, tunnel vision, derealisation and fluctuating energy that began shortly after foraging and eating wild mushrooms in September 2023. He also reported gastrointestinal distress, cognitive changes, motion-related visual disturbances, increased urinary frequency and episodes of numbness in the hands and feet.

Of critical importance was his work environment: his maintenance shed was heavily contaminated with visible black mould. He had also experienced two previous tick bites, raising the differential of tick-borne infection. A history of migraines following dental work in 2022 provided further context.

Presenting Symptoms

  • Persistent brain fog and cognitive slowing
  • Tunnel vision and motion-related visual blurring
  • Derealisation — a sense of disconnection from reality
  • Fluctuating, unreliable energy
  • Gastrointestinal distress
  • Increased urinary frequency
  • Numbness in hands and feet

Root-Cause Findings

Tick-borne infections were ruled out through clinical evaluation and testing. Urine mycotoxin testing confirmed multiple mould-derived toxins above reference range — the primary driver of the neurological, visual and fatigue symptoms:

  • Ochratoxin A: 7.8 ppb — significantly high. Known to affect energy, focus and neurological function.
  • Gliotoxin Derivative: 4.6 ppb — high. A strong mould-related toxin with neurological impact.
  • Trichothecene Group: 0.17 ppb — above normal limits. Often linked to indoor mould exposure.
  • Zearalenone: 0.56 ppb — borderline elevated, suggesting mild additional exposure.

The combination of occupational mould exposure through the contaminated maintenance shed and possible ingestion of mycotoxin-containing mushrooms explained the acute presentation and the severity of neurological symptoms.

The Programme

Phase 1 — Detoxification & Antioxidant Support

Gentle detoxification and antioxidant replenishment to help the body process and eliminate stored toxins. Liver pathways and cellular energy were supported with targeted nutritional and botanical agents. Liposomal glutathione, liver support nutrients, binders, calcium D-glucarate, turmeric/curcumin, and ubiquinol (CoQ10).

Phase 2 — Nasal & Sinus Restoration

Because exposure often occurs through inhalation, targeted nasal and sinus treatments cleared residual mould and biofilm build-up — improving breathing, focus and sinus health. Xylitol, EDTA, colloidal silver, propolis, and essential oil blends for biofilm disruption.

Phase 3 — Gut & Microbiome Rebalancing

Antifungal and probiotic support restored microbial balance and reduced systemic inflammation. Saccharomyces boulardii, antifungal botanicals (oregano oil, undecylenic acid, caprylic acid). Essential for stabilising digestion and immune resilience after mycotoxin-driven disruption.

Phase 4 — Nervous System & Visual Recovery

The final phase combined lifestyle and nervous system retraining methods with specific interventions for the visual and neurological symptoms: infrared sauna therapy, niacin sauna detox programme, cold showers, Buteyko breathing, polyvagal retraining, eye yoga exercises, 670nm near-infrared light therapy, guided meditation and neuroplasticity work.

Recovery Timeline

Over 12 months and seven structured treatment sessions, the toxicity questionnaire score dropped from 155 to 4 — and all neurological, visual and gastrointestinal symptoms resolved completely. A temporary regression at session 5 following a re-exposure episode was navigated without lasting setback, demonstrating the resilience that had been built into the system.

Session Progress

  • Session 1Score 155 — severe fatigue, brain fog, derealisation
  • Session 2Score 50 — energy improving, digestion stabilising
  • Session 3Score 68 — temporary flare, visual focus improved
  • Session 4Score 50 — clearer cognition, reduced urinary urgency
  • Session 5Score 66 — minor regression after re-exposure
  • Session 6Score 37 — strong, stable energy and clarity
  • Session 7Score 4 — symptom-free, full cognitive recovery
