New Research Reports Some Welders Develop Symptoms with a Parkinson’s Resemblance

Published in the medical journal Neurology, new research finds an increased incidence of mild movement disorder symptoms in career welders. Compared to non-welders, welders had an 11.7 percent reduction in a dopamine marker. Due to the small size of the study (only 60 participants total) more research is needed.

Welders are often exposed to manganese, a trace mineral that past research has linked to neurological disorders, including Parkinson's disease.

Study authors stress that the motor deficiencies observed in the welder study subjects are not demonstrative of classic Parkinson’s disease, but more of an off-shoot presumably resulting from dopamine deficiency.
