Unlabelled:
This study investigated the effects of mold exposure (ME) on human cognition by analyzing neuropsychological data from patients who were exposed to mold in their homes or workplaces. Compared to normative data, ME patients were impaired (<10th percentile) on a number of cognitive measures, with the most consistent deficits in visuospatial learning, visuospatial memory, verbal learning, and psychomotor speed. We also examined emotional functioning and found that a number of ME patients showed evidence of both Axis I and Axis II pathology. Interestingly, there was a significant correlation among patients' scores on the Beck Depression Inventory-Second Edition and the number of neuropsychological tests falling within the impaired range. Given the limited understanding of ME and its effect on the human central nervous system, we provide a working model that attempts to capture the complex interactions of impaired cognition, psychosocial stressors, poor physical health, and emotional functioning in patients following ME.

Insights
Mold exposure (ME) significantly impairs cognitive functions like visuospatial learning, memory, verbal learning, and psychomotor speed. Patients also experienced emotional difficulties, correlating with cognitive deficits.
Area of Science:
- Neuroscience
- Environmental Health
Background:
- Mold exposure (ME) is a potential environmental toxin impacting human health.
- Limited understanding exists regarding ME's effects on the central nervous system.
- Keywords: mold exposure, mild traumatic brain injury, toxic exposure.
Purpose of the Study:
- To investigate the impact of mold exposure on human cognition.
- To analyze neuropsychological and emotional functioning in mold-exposed patients.
- To propose a model for understanding ME's complex effects.
Main Methods:
- Analysis of neuropsychological data from mold-exposed patients.
- Comparison of patient performance against normative data.
- Assessment of emotional functioning using diagnostic criteria.
Main Results:
- Mold-exposed patients showed significant cognitive impairments (<10th percentile).
- Consistent deficits observed in visuospatial learning/memory, verbal learning, and psychomotor speed.
- Evidence of Axis I and Axis II pathology, with depression correlating to cognitive deficits.
Conclusions:
- Mold exposure leads to demonstrable cognitive impairments.
- Emotional dysfunction is prevalent and linked to cognitive deficits in ME patients.
- A multifactorial model is proposed to explain ME's impact on cognition, health, and emotion.
