First-line treatments
Anti-epileptic drug therapy
First-line pharmacologic management using anti-epileptic medications to control seizure activity. Choice of medication depends on seizure type and may require trial and error to find the most effective option.
Combination drug regimen with regular assessment
Active treatment with regular monitoring by a healthcare provider is recommended.
Epilepsy surgery - resection
Surgical removal of the dysplastic brain tissue when seizures are focal and medically intractable. Pre-surgical evaluation with MRI, EEG, and sometimes invasive monitoring is required to localize the epileptogenic zone.
Additional treatment options
Vagus nerve stimulation
Implantation of a device that delivers electrical stimulation to the vagus nerve, reducing seizure frequency and severity through neuromodulation. Often considered when surgery is not feasible or medications have failed.
procedureKetogenic diet
High-fat, low-carbohydrate diet that induces ketone body production and can reduce seizure frequency in some patients. Requires careful supervision by a dietitian and regular monitoring of nutritional status.
dietaryLong-term EEG and MRI monitoring
Regular neuroimaging and electrophysiological monitoring to track disease progression and seizure patterns. Essential for treatment planning and assessing surgical candidacy.
