Pathogens linked to Parkinson's Although pathogens have long been suspected to play a role in the neurodegeneration of Parkinson's and related diseases(see our linkurl:December 2010 feature),;http://www.the-scientist.com/2010/12/1/40/1/ very little is understood about the mechanics of the process. Specifically, scientists have been at a loss to explain what kills the dopamine-producing neurons in a region in the mid-brain that's important for movement -- resulting in motor problems such as tremors and paralysis.
