Prevention Of Parkinson's disease



Caffeine consumption appears protective against Parkinson's disease with a greater decrease in risk occurring with a larger intact of caffeinated beverages such as coffee increases. Although tobacco smoke decreases life expectancy and quality of life, it may reduce the risk of PD by a third when compared to non-smokers. The basis for this effect is not known, but possibilities include an effect of nicotine as a dopamine stimulant. Tobacco smoke contains compounds that act as MAO inhibitors that also might contribute to this effect.

Antioxidants, such as vitamins C and D, have been proposed to protect against the disease but results of studies have been contradictory and no positive effect has been proven. The results regarding fat and fatty acids have been contradictory, with various studies reporting protective effects, risk-increasing effects or no effects. Finally there have been preliminary indications of a possible protective role of estrogens and anti-inflammatory drugs.
