Parkinson's disease (PD) is a neurodegenerative brain disorder that progresses slowly in most people. Drinking coffee has been long associated with Parkinson's disease, but a study has recently revealed that drinking coffee may not reduce symptoms of Parkinson's disease.
Parkinson's disease is a disorder of the central nervous system that affects movement, often including tremors. The results indicated that caffeine cannot be recommended as therapy for movement symptoms of Parkinson's disease. Researchers from McGill University in Montreal, Canada showed that coffee may not relieve the symptoms of Parkinson's disease.
A more in-depth investigation has shown that the beverage did nothing to alleviate sufferers' crippling symptoms. Study author Dr Ronald Postuma said that caffeine, which is so safe and inexpensive, has been linked to a reduced risk of developing Parkinson's. "So, it was exciting to think that it could possibly help people who already have the disease," Postuma added.
The study participants were followed for six to 18 months. The findings indicated there was no improvement in movement symptoms for people who had taken the caffeine capsules compared to those who took the placebo capsules. There was also no difference in quality of life. Dr Postuma stated that while previous study showed possible improvement in symptoms but that study was shorter, so it's possible that caffeine may have a short-term benefit that quickly dissipates.
The research appears in online issue of Neurology.
