Study finds potential link between welding fumes, Parkinson's disease. HealthDay (4/6, Preidt) reported, "Manganese in welding fumes may affect welders' brains over time," according to a study in the journal Neurology. This patient population included "20 welders with no symptoms of Parkinson's disease, 20 Parkinson's disease patients who were not welders, and 20 healthy people who were not welders." The welders had "average manganese levels" that were "two times the upper limits of normal." The participants underwent "brain PET and MRI scans and motor skills tests, and were examined by a movement disorder specialist." Compared to non-welders, the welders had an "average 11.7 percent reduction in a marker of the neurotransmitter dopamine in the same area of the brain affected by Parkinson's disease." The researchers also found that welders had "mild movement disorders."
