When tea and caffeine were included in the assessment the risk of Parkinson's Disease reduced in relation to the intake. The risk of Parkinson's Disease was reduced by 26% for every two cups of tea consumed and by 17% for every 200mg of caffeine taken. The association of coffee and tea consumption with the risk of Parkinson's Disease was stronger for men than it was for women. The association of caffeine consumption with the risk of Parkinson's Disease was stronger in postmenopausal women when they had ever used hormones. These associations were weaker in the USA than they were in Europe and Asia.
Caffeine and theophylline, which is found in tea, are a type of drug called adenosine antagonists. Adenosine antagonists include drugs presently being developed for the treatment of Parkinson's Disease including : Preladenant, Tozadenant, and Istradefylline
