A new study has found that coffee drinkers are less likely to develop Parkinson's disease. Researchers tracked over 184,000 people for 13 years. They found coffee drinkers had a lower risk of Parkinson's. Blood tests showed caffeine metabolites were linked to reduced risk. The study suggests caffeine keeps dopamine flowing in the brain. This could help prevent Parkinson's, a disease marked by dopamine loss. The top 25% of coffee drinkers were 40% less likely to get Parkinson's. Although this study can't prove coffee prevents Parkinson's, it adds to growing evidence. Understanding caffeine's impact on the brain may lead to new prevention strategies. Nearly a million Americans live with Parkinson's today.
