COFFEE INTAKE AND THE RISK OF DYSKINESIA

Movement Disorders [2013] 28 (3) : 380-383 (A.M.Wills, S.Eberly, M.Tennis, A.E.Lang, S.Messing, D.Togasaki, C.M.Tanner, C.Kamp, J.F.Chen, D.Oakes, M.P.McDermott, M.A.Schwarzschild)� Complete abstract

Caffeine is a naturally occurring adenosine antagonist that is commonly found in coffee, and to a lesser extent in tea, cola drinks, cocoa, and chocolate. Adenosine antagonists reduce or prevent the development of dyskinesia in animal models of L-dopa induced dyskinesia.

Researchers examined the association between the intake of caffeine and� the time taken to develop dyskinesia. Those people who consumed 12 ounces of coffee per day, which is about two cups, reduced their likelihood of developing dyskinesia to 61%. Those people who consumed 4 to 12 ounces of coffee per day, which is less than two cups per day, reduced their likelihood of developing dyskinesia to 73%. The authors suggest tha these results support the possibility that caffeine may reduce the likelihood of developing dyskinesia. For a printable version of this article click here.�
