Welding fumes 'linked to brain injury'RSS Feed

People who are exposed to welding fumes could be at an increased risk of developing brain injury, research has shown.

A study, published in journal Neurology, indicated that exposure to welding fumes put people at a higher risk of suffering a brain injury in the same region of the brain that is also involved in Parkinson's disease.

Brad A Racette, of the Washington University School of Medicine in St Louis, explained that MRI scans also identified brain changes in welders which were consistent with manganese deposits.

"While these changes in the brain and dopamine dysfunction may be an early marker of neuron death related to welding exposure, the damage appeared to be different from those of people with full-fledged Parkinson's disease," he said.

This comes after researchers at the University of Oxford developed a new way of delivering drugs to the brain which could lead to new therapies for people with Parkinson's disease as well as Alzheimer's, motor neurone disease and other neurodegenerative disorders.
