title: Paroxysmal Kinesigenic Dyskinesia.
abstract: We present a case of paroxysmal kinesigenic dyskinesia (PKD) in a 21 year old girl, with no family history of similar episodes. The episodes were short (lasting less than a minute), frequent, occurring 5 to 10 times a day, self-limiting dystonia of her right upper limb precipitated by sudden movement. She also had a past history of partial seizures with secondary generalization in her childhood. She responded to phenytoin, with cessation of events after 1 month of treatment. This case impresses upon the hypothesis stating the association between seizure activity and PKD probably due to a common foci of origin. Awareness of this condition is required as it is easily treatable but frequently misdiagnosed.
