The evaluation of the health state of the workers occupationally exposed to low concentration of carbon disulphide (CS2). Part two: The complex way of the examination of the central nervous system (CNS).
The results of evaluation of health state of CNS of 114 healthy workers occupationally exposed to CS2 were demonstrated. The concentration of CS2 in the air was 0-65 mg/m3. 62 people from the control group underwent an examination in the same way--before employment and after 5 years. Psychiatric examination, psychological organic tests (Bender, Graham Kendall, Benton) and EEG record were performed. The examination results were evaluated separately and together by means of arbitrary scale of pathological changes which constituted a complex evaluation of CNS. A considerable deterioration of CNS was stated which was reflection of pathological changes of a functional type. After 5 years this complex way of evaluation of CNS in exposed workers significantly more pathological changes was evidenced then ones in the control group. In 20 exposed men who obtained the worst results in the evaluation of CNS, the head computer tomography was performed. In 60% mentioned people cortical and/or subcortical atrophy was found, described in most people to be small. At the same time it is important to state that mentioned CNS examination enables an early evaluation of functional and morphological state of CNS in people who are occupationally exposed to low concentration of CS2.
