We describe a 51‐year‐old man who developed awake bruxism during the course of multiple system atrophy. Electromyographic studies revealed side‐to‐side amplitude asymmetry of the bursts of motor activity. The bruxism responded favourably to low‐dose levodopa–carbidopa therapy. Possible mechanisms of this rare association are discussed. © 2003 Movement Disorder Society
