Abstract
Paroxysmal kinesigenic dyskinesia (PKD) is a diagnostic term for transient, involuntary abnormal movements triggered by sudden motions. The treatment for PKD differs from other paroxysmal dyskinesias, as it notably responds well to sodium channel blockers. We report a case of atypical PKD, coupled with paroxysmal exercise-induced dyskinesia (PED).
Both PKD and PED in this patient showed a good response to oxcarbazepine. This case could be clinical evidence that paroxysmal dyskinesias could potentially be regarded as a spectrum disorder with overlapping features.
