Caffeine inhibits Parkinson's disease

In the past six months, two studies in the United States have shown that drinking more coffee can reduce the incidence of Parkinson's disease. Alberto Ascherio, a professor at the Harvard School of Public Health in the United States, pointed out at the 125th annual symposium of the American Association of Neurology on October 19th that people who drank one to three cups of coffee or other caffeinated drinks a day were 60% less likely to develop Parkinson's disease than those who did not drink coffee.

A follow-up study of 88565 women and 47355 men led by Ashley found that men who drank coffee or caffeinated drinks daily were 60% less likely to develop Parkinson's disease than men who did not touch caffeine. However, the study does not seem to see any effect of caffeine consumption on Parkinson's disease in women. That means caffeine consumption only affects men.
