Myoclonic seizures occur in several different types of childhood epilepsy. Most epilepsies arise in childhood and have a genetic cause. Conversely, patients with myoclonic atonic epilepsy, myoclonic epilepsy of infancy, and PCDH19-associated epilepsy may be misdiagnosed with Dravet syndrome (Wirrell 2017).

Patients with benign forms of myoclonic epilepsy often respond well to valproic acid or clonazepam. Myoclonic seizures may be precipitated by treatment with LTG and CBZ in children with rolandic epilepsy with neurophysiological evidence of epileptic negative myoclonus. Like other forms of seizures and epilepsy, myoclonic seizures are best addressed through an individualized approach. Benign myoclonic epilepsy in infant.
