Small study of caffeine in PD

Abstract

"This is a small study of treatment with caffeine in Parkinson's. Previous studies suggest that people who drink coffee are less likely to be diagnosed with Parkinson's. Reasons for this observation include: 1) caffeine protects you against Parkinson's, 2) coffee delays the onset of Parkinson's or 3) people with early undiagnosed Parkinson's do not get the normal positive effect from coffee and therefore don't use it. Whatever the reason, caffeine remains a good candidate drug for treating Parkinson's. This small study shows some benefit from treatment with caffeine in certain aspects of the disease and not in others. It also suggests a dose that can be tolerated. Clearly larger studies are warranted."
