Earlier researches tied the intake of caffeine to the prevention of Parkinson’s disease, however a new research study reveals that caffeine promises improvement in the disease’s most common symptoms. 61 Parkinson’s patients took part in a random trial in which the participants that took 200 milligram caffeine tablets two times in a day resulted in their motor symptoms become less disruptive, like slow movement and stiffness than those patients that took placebo pill. Even though it was not noteworthy, improvement was also seen with daytime sleepiness.
Investigators expected the results to be more pronounced in larger trial. However, patients with uncontrolled blood pressure or irregular heart rhythms should consult a doctor before trying it. The research study would be undergoing further analysis and detailed study.
Regarding the research many questions have arisen, like if patients would develop a caffeine tolerance eventually blunting the benefits of coffee or caffeine pills. Talking about the research, Dr. Ronald Postuma, lead researcher, from McGill University in Montreal said, "It's a bit too early to say, 'Everybody should be drinking coffee. Does it really make a difference over years of Parkinson's disease? I don't think we know.”
The number of people diagnosed with Parkinson’s every year is about 50,000 to 60,000 in the United States.
