Study: Parkinson’s Disease and Other Basal Ganglia or Movement Disorders in a Large Nationwide Cohort of Swedish Welders

Epidemiological linked-registry cohort study of almost 50,000 Swedish welders, followed for an average of 29 years, compared to an age and geographical matched control group of close to 500,000 Swedish non-welders, to evaluate increased risks of Parkinson’s disease or other basal ganglia and movement disorders for welders. This nationwide linked-registry study compares the rates of hospitalization and death for the two groups and concludes that there is no support for a relation between welding and Parkinson’s disease or any other neurodegenerative disorders.

Study: A Cohort Study of Parkinson’s Disease and Other Neurodegenerative Disorders in Danish Welders

Epidemiological cohort study used data collected over a 25-year period to evaluate the prevalence of Parkinson’s Disease, as well as other neurodegenerative disorders including manganism, in a group of 9,817 male workers who were either welders or exposed to welding fumes while working in departments where mild or stainless steel welding occurred. This large study with long-term follow up concluded that men who engaged in mild and stainless steel welding did not have increased hospitalizations for Parkinson’s Disease or other neurodegenerative disorders and that welders were no more likely to develop Parkinson’s Disease or other neurodegenerative diseases than the general public of Denmark.
