Paroxysmal kinesigenic dyskinesia is a rare hyperkinetic movement disorder, characterized by short duration dystonic or choreoathetotoid movements precipitated by sudden movement, a change in position, or hyperventilation. It can be difficult to distinguish this syndrome from seizures. We report a case of 15 years old boy and his 53 years old father, who presented with abnormal involuntary unilateral dystonic movements triggered by sudden movement and would last few seconds. All symptoms showed excellent response to carbamazepine. Although an uncommon movement disorder, it is important to recognize clinical presentation of paroxysmal kinesigenic dyskinesia as most patients respond very well to medical treatment.
