We report two male patients with juvenile myoclonic epilepsy. They had been diagnosed as having partial epilepsy for three years. They had various myoclonic seizures characterized by truncal and head torsion, stepping backward, and inability to reach objects, as well as asymmetric myoclonic jerks of the upper extremities. For early diagnosis of juvenile myoclonic epilepsy, it is important to take account of the variability of myoclonic seizures.
