title: [A case of atonic partial seizure].
abstract: This report presented a 4-year-old girl who had atonic partial seizure of the right leg accompanied by impaired equilibrium. This patient had a generalized tonic-clonic seizures before, and had been on anticonvulsant medication. Mild cataplexy of the right leg and flail trunk while standing occurred abruptly. Based on clinical symptoms, physiological findings, and an electroencephalogram taken at the time of seizure, the cataplexy of the right leg was diagnosed as epileptic seizures. After the dosage of anticonvulsant drug was increased, all symptoms disappeared completely. Cases of atonic partial seizure have been reported only rarely. In our case, atonic partial seizure was associated with nonepileptic equilibrium impairment, probably due to cerebral cortex dysfunction. This is an extremely rare occurrence.
