متن کاملThe neuropathology of manganese-induced Parkinsonism.
Manganese is an essential trace metal that is widely used in industry, particularly in the manufacture of steel. Exposure to high levels of manganese can cause neurotoxicity with the development of a form of parkinsonism known as manganism. It has recently been hypothesized that manganese exposure might also cause or accelerate the development of Parkinson disease (PD). This article is a review...
