‘All forms of myoclonus, whether massive or bilaterally symmetrical, segmental, or fragmentary, can occur with almost every type of epilepsy’ (Aicardi 1986). Two major categories of epileptic myoclonus can be distinguished. First, there is cortical myoclonus producing epilepsia partialis continua, Jacksonian partial seizures, secondary generalized tonic-clonic seizures, multifocal cortical myoclonus, or generalized cortical myoclonus. All these types of epilepsy are due to focal cerebral cortical discharge with secondary generalization. Second, there is generalized myoclonus in the primary generalized epilepsies, which we call epileptic myoclonus.
