Neuropsychological effects of industrial toxins: a review

Quantitative assessment of nervous system function is essential in characterizing the nature and extent of impairment in individuals experiencing symptoms following workplace exposure. In recent years, the application of standardized neuropsychological tests to the evaluation of exposure to toxic industrial substances has significantly increased the understanding of the effects of these compounds. Within this review, the specific toxic neuropsychological effects of lead, carbon disulfide, trichloroethylene, perchloroethylene, mercury, styrene, and pesticides are discussed in detail. These discussions draw on our clinical experience with patients exposed to these substances as well as material from the medical literature. Factors affecting the utilization of these tests in occupational settings are also considered.
