Neurodegenerative diseases pose an increasing challenge to public health as the population ages.
Its etiology is essentially unknown, but environmental neurotoxins may be involved. Both were associated with occupational exposure to lead. After adjusting for age and gender, both blood and bone lead levels were higher in cases, and cases were more likely to have occupational exposure to lead. Further analyses will be conducted to confirm these findings and explore the effects of other neurotoxins. In addition, dietary antioxidant intake will be evaluated as a protective factor and as a modifier of other exposure-disease relationships.
