A new clinical study published in the journal Parkinsonism and Related Disorders links higher caffeine consumption to slower development of Parkinson's symptoms after diagnosis.
Following the progression of Parkinson's
Researchers studied the progression of Parkinson's symptoms over 4 years in 79 people who had been newly diagnosed with the condition.
They found that higher caffeine consumption, from drinks like tea and coffee, was linked to the development of fewer motor and non-motor symptoms, and lower symptom severity.
The study also found that people who drank more caffeine started Parkinson's medication, such as levodopa, later compared to those with lower caffeine consumption.
Behind the headlines
Claire Bale, our Head of Research Communications, comments:
"Some studies have suggested that higher caffeine consumption may slightly reduce the risk of developing Parkinson's and have beneficial effects on some symptoms.
"These findings are interesting but we need to see more evidence from larger clinical trials before we can recommend that people with Parkinson's should drink more coffee.
"Although many of us consume caffeine on a daily basis, it is a drug and it can have side effects, especially if you're someone who isn't used to it.
"We would recommend talking to your GP or nurse before making any significant changes to your caffeine intake."
