Researchers are still looking for effective methods that can alleviate Parkinson's symptoms. In one of those studies, carried out by the McGill University Health Center of Canada, they have proven that caffeine could help to control the involuntary movements suffered by these patients.
In the study, a group of patients with Parkinson's was divided into two, half was given a placebo and the other half was given three weeks of 200 milligrams of caffeine daily, and 400 mg of the three next weeks.
The effects of this study on caffeine and Parkinson's have been only "marginal", so they recommend it simply as a "supplement to the medication"
The researchers used caffeine to study how it affected sleepiness. It is already known that this substance temporarily reduces fatigue and increases alertness. By acting on the central nervous system and the cardiovascular system, the experts analyzed how their consumption influenced the most common motor symptoms of the disease, from muscle stiffness to lack of balance, to slowness of movement or tremors.
The results indicated that individuals who had received caffeine managed to improve their symptoms on a scale of five points with respect to the others. However, researchers have indicated that the effects have been only "marginal", so they recommend it simply as a "supplement to the medication", either through coffee or tea.
