The story also quotes Dr. Double, who said, "We believe this loss of neurons results from a combination of oxidative stress [cell damage] and a regional deficiency in copper, both of which occur specifically in vulnerable regions of the Parkinson’s disease brain."
These data and others continue to implicate genetic and environmental factors that contribute to oxidative stress in the pathogenesis of neurodegenerative disease and emphasize the need for identifying those at risk early when efforts to reduce oxidative stress have the greatest potential to slow subclinical disease progression and forestall the emergence of debilitating clinically overt symptoms.
