Carbamazepine-induced abnormal movements have been reported in children and adult patients, and both non-epileptic myoclonus and tic-like movements have been reported in the same patient. Although a pathogenetic mechanism underlying carbamazepine-induced epileptic negative myoclonus has been proposed, a causative role of carbamazepine for positive myoclonus has not been fully identified. Here, we describe the video-documented case of an adult patient with non-epileptic myoclonus and tic-like movements persisting for 21 years, which appeared after he started carbamazepine treatment at 10 years of age.
