In recent years, people have more and more contact with coffee, especially those who need to stay up late at work. However, many people have doubts about whether coffee will bring us health or harm. Caffeine may help reduce motor symptoms in people with Parkinson's disease, according to a study published in the 2012 issue of Neurology.

However, a recent more in-depth study may overturn the claim that coffee may not be effective in relieving severe symptoms of Parkinson's disease.

The study's author, Ronald Potoma of McGill University in Canada, said 121 patients with Parkinson's disease were involved in the new study, with an average age of 62 years and an average age of 4 years. Half of the participants took a 200 mg caffeine capsule twice a day, equivalent to three cups of coffee a day, in the morning and after lunch, while the other half took a placebo capsule.

The researchers followed the participants for 6 to 18 months. To help half of the participants adapt to caffeine, start with a placebo, gradually increase the dose, and then increase to 200 milligrams at the ninth week.

In the course of the study, it was found that participants who took caffeine capsules had no improvement in motor symptoms and no difference in quality of life compared with those who took placebo capsules, so the study was terminated.
