Does an increase in vitamin E help those with Parkinson's?

Although there has been much interest in vitamin E for multiple neurodegenerative diseases, there is not compelling data to suggest that there a role for vitamin E in the treatment of Parkinson's Disease. Further, there is not good data to support a role of vitamin E in slowing the disease progression. There were several reports of vitamin E slowing or preventing parkinsonism in animal models of PD, but human studies did not replicate these findings.
