The cause(s) of PD remain to be elucidated; multiple pathogenic mechanisms have been proposed, ranging from oxidative stress to protein aggregation, and mitochondrial dysfunction.1,4 The slide shows how the range of potential risks and disease mechanisms may all interact to lead to the development of pathology.1,2 Some have argued that, because the environment can be changed unlike a person’s genetics, the environmental factors underlying PD should be the focus of preventing PD in the future.5,6
