Myoclonic Seizures in Adults — What to Do After Combination Antiepileptic Drug Therapy Has Not Achieved Freedom from Seizures
This protocol applies to adults aged 16 years and older with progressive myoclonic epilepsy who continue to experience myoclonic seizures despite treatment with combination antiepileptic drug therapy.
Clinical Scenario
Adults 16 years of age and older with progressive myoclonic epilepsy presenting with myoclonic seizures that remain uncontrolled on pharmacologic treatment.
Prior Treatment — Goal Not Reached
Combination therapy using two or more antiepileptic drugs was the initial approach, with the goal of achieving
freedom from seizures. This protocol is indicated when that goal has not been met.
Next-Line Approach (partial overview only)
For medically refractory epilepsy in this setting, management shifts toward nonpharmacologic strategies. These include, among other options, a specific structured dietary intervention and neurostimulation-based approaches. The full structured regimen — including all options, criteria, and clinical decision points — is accessible via the link below.
Treatment Goal
Decreased frequency or elimination of seizures.

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.
The ketogenic diet, a high-fat, low-carbohydrate, and low-protein diet, induces ketone body formation.
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.
