Study Type / Design:
Narrative clinical review delineating neurologic and neuropsychiatric symptom clusters attributed to exposure in water-damaged buildings and to mycotoxins.
Population & Exposure Type:
Adults and children with direct exposure to damp/moldy indoor environments (residential and occupational).
Main Findings
- Recurrent neurologic/ neuropsychiatric symptoms: headaches, cognitive slowing, memory issues, disequilibrium, paresthesias, tremor, mood changes.
- Emphasizes syndrome features that can resemble classic neurologic disorders (e.g., movement disorders, delirium, dementia) and the need to differentiate them neurodiagnostically.
- Notes improvement with exposure cessation is frequently observed.
Effect Size / Strength:
Descriptive (no pooled estimates). Consistency of symptom clusters reported across clinical observations.
Causation Level:
Associative → possible causal, based on consistent clinical patterns and improvement after avoidance; acknowledges diagnostic uncertainty.
Notes / Limitations:
- Not a meta-analysis; it relies on clinical observations and literature synthesis.
- Exposure is often assessed by history/inspection rather than quantitative biomarkers.

Study Type :
Design case reports (n=2) + focused literature review.
Population & Exposure Type:
Two adults with prolonged direct residential exposure to a severely water-damaged, high-mold environment; both developed CIDP confirmed by neurophysiology (and sural nerve biopsy in one case).
Main Findings
- Temporal association between high indoor mold exposure and new-onset CIDP (immune-mediated demyelinating neuropathy).
- Clinical features: sensorimotor deficits, electrophysiologic demyelination; co-occurring symptoms included fatigue, asthma, neurocognitive complaints.
- Authors advise clinicians to screen for environmental exposures (water damage/mold) in unexplained CIDP presentations.
Effect Size / Strength:
Case-level evidence; no incidence estimates. Provides biologic plausibility and temporal linkage, not proof of population-level risk.Causation Level epidemiology. Indeterminate (case reports cannot establish causality). Suggestive signal warranting further
Notes / Limitations
- Small sample (n=2); lacks controls.
- Potential confounders not fully excluded; cannot infer prevalence or risk magnitude.

Why this paper is crucial:
- It provides systematic, population-level data on neurological and autonomic symptoms among employees exposed to damp/moldy environments , something earlier neurological papers (Empting; Lieberman) lacked.
- It includes validated questionnaires, clinical neurocognitive testing, and comparisons with unexposed controls, adding quantitative weight to an otherwise case-dominated field.
- The study population (hospital staff, n ≈ 200) represents occupational chronic exposure, bridging environmental medicine and workplace safety.
Key Verified Findings
- Workers from the moisture-damaged hospital reported neurological symptoms—concentration problems, dizziness, tremor, fatigue—3–5 times more often than unexposed reference staff.
- Multiple Chemical Sensitivity (MCS) occurred in ≈ 40 % of exposed vs 9 % of controls (p < 0.001).
- Objective neuropsychological tests confirmed slower reaction times and reduced working-memory performance among exposed employees.
- The authors concluded that systemic inflammatory or neurotoxic processes triggered by damp/mold exposure could underlie the findings.
- Symptom reduction was documented in staff relocated to clean facilities (follow-up study, Vilén et al., 2022).

“Exposure to moisture-damaged indoor environments was associated with a high prevalence of neurological and autonomic nervous system symptoms, supporting earlier observations that these environments can affect the central nervous system.” — Hyvönen et al., 2020, p. 380.
Causation Level:
Probable associative — strong temporal and exposure–response pattern; mechanistic plausibility (β-glucan and inflammatory mediator activation), but no direct causal biomarker proof yet.
Notes / Limitations:
Cross-sectional design (cannot confirm temporal onset); symptom self-report partially ubjective; however, neurocognitive testing and occupational cohort design add robustness.
