The Monday Morning Stimulus

Caffeine has been associated with a reduced risk of developing Parkinson's disease, but a new study says a coffee jolt might not be good for people already diagnosed with the brain disorder. Consuming caffeine appears to blunt the brain's ability to use dopamine, the hormone that lies at the heart of Parkinson's symptoms, researchers reported recently in the journal Annals of Neurology.

Patients with high caffeine consumption had an 8% to 15% greater decrease in the ability of dopamine to bind with receptors in the brain, compared to those who took in less caffeine, results show.

"While caffeine may offer certain benefits in reducing risk of Parkinson's disease, our study suggests that high caffeine intake has no benefit on the dopamine systems in already diagnosed patients," said principal researcher Valtteri Kaasinen, a professor of neurology with the University of Turku in Finland.
