A follow-up study led by the University of Turku and Turku University Hospital in Finland examined how caffeine consumption affects brain dopamine function over an extended period in patients diagnosed with Parkinson’s disease. The dopamine function of the brain was assessed with single photon emission computed tomography to measure dopamine transporter binding.
Caffeine consumption had no effect on Parkinson’s symptoms A clinical study compared 163 patients with early-stage Parkinson’s disease to 40 healthy controls. The examinations and imaging were conducted on two occasions for a subsample, with an average interval of six years between the first and second imaging session.
