||30 men (age 20-64 years) who had been exposed to 0.19-0.45mg/m3 of manganese for 1-45 years at manganese steel smelters and 60 controls (age 22-65 years) were examined. The investigation covered: a general health inquiry; brainstem and cerebral auditive evoked potential (AEP); EEG and diadochokinesometry; simple and complex reaction time, finger tapping, digit span, mental arithmetic, vocabulary, a coding task and manual dexterity; diagnostic interview scheme (DIS), dynamic rating scale for neurasthenic syndrome (DNS) and comprehensive psychopathological rating scale (CPRS). No group differences concerning health, EEG or the psychiatric examinations were found. Diadochokinesis was slower, cerebral AEP latency increased, reaction time and tapping digit span were impaired in the exposed group. These effects are interpreted as early signs of disturbances of the same type as parkinsonism.
