Manganese and Parkinson's disease: a critical review and ...

Background: Excess accumulation of manganese (Mn) in the brain results in a neurological syndrome with cognitive, psychiatric, and movement abnormalities. The highest concentrations of Mn in the brain are achieved in the basal ganglia, which may precipitate a form of parkinsonism with some clinical features that are similar and some that are different to those in Parkinson's disease (PD).

Manganese-Induced Parkinsonism and Parkinson’s Disease ...

2015-7-6 Manganese (Mn) is an essential trace element necessary for physiological processes that support development, growth and neuronal function. Secondary to elevated exposure or decreased excretion, Mn accumulates in the basal ganglia region of the brain and may cause a parkinsonian-like syndrome, referred to as manganism.

Toxicity of Manganese - an overview ScienceDirect Topics

The majority of these exposures are via inhalation of manganese dust, as in mining, or volatilization and inhalation of manganese fumes from manganese substrates during smelting and welding (Huang et al., 1989; Hudnell, 1999). Our current understanding suggests that inhalation of particulate manganese is able to bypass the blood–brain barrier ...

2021-10-21 Manganese is an essential trace metal. The dysregulation of manganese seen in a broad spectrum of neurological disorders reflects its importance in brain development and key neurophysiological processes. Historically, the observation of acquired manganism in miners and people who misuse drugs provided early evidence of brain toxicity related to manganese exposure.
