A new study has found a dose-dependent relationship between coffee consumption and reduced severity of tremors in men with Parkinson disease.
Previous research has established that coffee is a negative risk factor for PD, a neurodegenerative disorder that produces motor symptoms, including tremor, as well as nonmotor symptoms. Based on mouse models, investigators have hypothesized that the caffeine in coffee offsets the loss of striatal dopamine and dopamine transporter binding sites seen in PD. There have been few studies that assessed how coffee consumption may be linked with the motor symptoms of PD, and they have suggested that coffee consumption has a positive effect.
