A Case Of Paroxysmal Kinesigenic Dyskinesia Suspected To Be Reflex Epilepsy

An 11-year-old male patient developed weakness or right arm elevation after sudden movement at the age of eight. Reflex epilepsy was initially suspected; however, magnetic resonance imaging and electroen-cephalography (EEG) revealed no abnormality. Video-EEG monitoring was performed, but no change was noted during attacks of weakness. He was diagnosed with paroxysmal kinesigenic dyskinesia (PKD) and carbamazepine has stopped his attacks. PKD is a rare neurological disorder characterized by brief attacks of involuntary movement triggered by sudden voluntary movements, which may be confused with reflex epilepsy. PKD should be considered as a differential diagnosis of reflex epilepsy.
