Chronic neurotoxicity of lead is a major problem in all countries around the world. Long-term exposure to lead in the environment has recently become of interest as a possible risk factor for cognitive impairment in workers exposed to lead. The consequences for the brain after cessation of the exposure are also subject to research. The aims of our study were: to investigate and analyze cognitive impairment in workers in professional contact with lead. For the purpose of the study, a total of 72 workers in chronic professional contact with lead aerosols were examined. The investigated men (n = 72) were aged 39.4 ± 10.4 (19 - 58) years with an average duration of service of 13.0 ± 8.7 (1 - 33) years and mean lead concentration in blood of 43.4 ± 9.0 μg / dl. The screening set included a subjective cognitive impairment survey, a depression scale, a set of cognitive tests (MMSE, IST, DRT, CDT), and a scale for activities of daily living (4-IADL Score).
