An increase in the Manganese concentration in the brain is a critical step in Mn neurotoxicity, also known as manganism. It is important question whether the neurobehavioral dysfunctions, which are often found in Mn-exposed welders, are associated with structural brain abnormalities in Mn-exposed welders. Voxel-based morphometry demonstrated voxel-wise comparisons of gray and white matter at a whole-brain level, has been useful in characterizing subtle changes in brain structure in a variety of diseases associated with neurological and psychiatric dysfunction. the present research showed significant correlations between several neurobehavioral deficits and volumetric indices.
