Treatment of Epilepsy with Myoclonic Seizures in Children Under 16
Clinical Scenario
This protocol addresses epilepsy presenting with myoclonic seizures in patients younger than 16 years. Characteristic features include rhythmic myoclonic jerks of the shoulders and arms with tonic abduction, resulting in progressive lifting of the arms during the seizure.
Management Overview
For medically refractory cases, the approach may involve a specialised dietary strategy or a neuromodulation-based intervention. Eligibility criteria differ across options, and the sequencing of these alternatives follows a structured clinical algorithm — available in full via the protocol below.

- Rhythmic myoclonic jerks of the shoulders and arms with tonic abduction that results in progressive lifting of the arms during the seizure are typical.

- For patients with seizures that are not controlled with these agents, alternative treatments include surgical resection of the seizure focus, ketogenic diets, vagus nerve stimulators, and implantable brain neurostimulators.
- Surgical resection of the seizure focus in appropriately selected patients often results in decreased frequency or elimination of seizures with improvement in quality of life.
- The ketogenic diet, a high-fat, low-carbohydrate, and low-protein diet, induces ketone body formation.
- Vagus nerve stimulation may increase seizure-free time in patients with medically refractory epilepsy who are not candidates for surgery or in whom surgery has been ineffective.
- It is approved by the U.S. Food and Drug Administration for use in persons older than 12 years.
