[Value of multimodal evoked potentials in the assessment of the neurotoxic effects of carbon disulphide].
Central nervous system dysfunction among CS2-exposed workers was studied by measuring short latency SSEPs and VEPs. The examinations were done in 40 men. Chronic CS2 intoxication was diagnosed in 21 of them. Latency of N19, N11, N20 of somatosensory evoked potentials and latency of P100 wave of visual evoked potentials were statistically significant longer in CS2 exposed group in comparison with controls. The amplitude of N20 SSEPs was also significantly higher. Increase of N20 amplitude (33 persons) and elongation of its latency (25 persons) were frequent abnormalities of SSEps. In individual assessment of VEPs, most frequent were: abnormal difference in interocular latency of P100 (26 persons) and elongation of P100 latency (25 persons). In the analysed SSEPs and VEPs parameters there was no significant difference between two clinical groups. The authors conclude that the CS2--neurotoxic effect leads to impairment of the peripheral and central part of the somatosensory pathway, as well as to central dysfunction of the visual pathway.
