At this time, doctors have no means for the prevention of Parkinson’s disease (PD). They hope to identify a biomarker – a factor shared by all affected people – that could lead to a standard, accurate test for the disorder. When the genetic mechanisms are finally identified, the means for preventing Parkinson’s by treating mutations may be possible. While no treatment cures the disease, early intervention with proven therapies may help slow the onset of symptoms and reduce their intensity for as long as possible. Although no clinical evidence exists, consuming coffee, green tea and other antioxidants may prevent production of free radicals that may attack nerve cells that produce dopamine.
