United States – Claims made in the Annals of Neurology, have also served to question the previous view that could help in averting Parkinson’s disease through caffeine intake. In fact, it deem the brain less capable of using dopamine, the chemical associated with Parkinson, when coffee is ingested, as reported by HealthDay.
Impact on Dopamine Function
According to a research study undertaken by the University of Turku in Finland under the supervision of demography Professor Valtteri Kaasinen, high caffeine consumers have their dopamine receptor binding capacity reduced by 8% – 15% compared to their counterpart consumers of low caffeine. This means that even though the substance, caffeine, reduces the possibility of Parkinson’s, it has no positive impact on patients who already have the disease.
Brain Imaging Insights
To better explore these results, 163 patients with early-stage Parkinson’s disease and 40 participants free of the disorder underwent brain imaging. The findings presented by this study indicated that daily caffeine consumption contributes to the regulation of dopamine neurotransmitter and, consequently, the development of symptoms of Parkinson’s disease, as reported by HealthDay.
Implications for Treatment
Despite the issue that causes questions regarding the actually efficient impact of caffeine for the Parkinson’s treatment, researchers considered that the decrease of the dopamine function, which has been observed, is not equal to the caffeine-caused neurons death. Instead, it implies a more global occurrence, unrelated to caffeinated drinks and offering a fresh perspective on the multifaceted pathways involved in Parkinson’s disease.
