Paroxysmal kinesigenic dyskinesia (PKD) is characterized by brief, frequent episodes of abnormal movements that are precipitated by sudden involuntary movement of the body, arms, and legs. The clinical presentation is not limited to chorea or athetosis, variations may present with chorea, athetosis, dystonia, or a combination of these hyperkinetic movements. PKD is an uncommon disorder that usually has its onset between 6 and 16 years. Because there was not a clear distinction between PKD and epilepsy, the patients had no idea whom to consult for their condition. PKD may remit spontaneously with age, the patients usually respond well to anticonvulsants, especially carbamazepine. We report three cases of PKD, and will discuss the pathophysiology, clinical characteristics, treatment of these patients.
