Adenosine A2A receptor antagonists reduce or prevent the development of dyskinesia in animal models of levodopa-induced dyskinesia. We examined the association between self-reported intake of the A2A receptor antagonist caffeine and time to dyskinesia in the Comparison of the Agonist Pramipexole with Levodopa on Motor Complications of Parkinson’s Disease (CALM-PD) and CALM Cohort extension studies, using a Cox proportional hazards model adjusting for age, baseline Parkinson’s severity, site, and initial treatment with pramipexole or levodopa. For subjects who consumed > 12 ounces of coffee/day, the adjusted hazard ratio for the development of dyskinesia was 0.61 (95% confidence interval, 0.37–1.01) compared to subjects who consumed < 4 ounces/day. For subjects who consumed between 4 and 12 ounces/day, the adjusted hazard ratio was 0.73 (C.I. 0.46–1.15) (test for trend, p = 0.05). These results support the possibility that caffeine may reduce the likelihood of developing dyskinesia.
