Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Antiepileptic Drug Therapy
Aggressive pharmacologic seizure control using appropriate antiepileptic medications. Drug selection based on seizure semiology and EEG findings. Therapeutic drug monitoring and side effect management are essential components.
Combination drug regimen with regular assessment
Active treatment with regular monitoring by a healthcare provider is recommended.
Resective or Disconnective Epilepsy Surgery
Surgical intervention for drug-resistant epilepsy, including focal resection, lobectomy, or corpus callosotomy based on seizure localization. Requires comprehensive multidisciplinary evaluation for candidacy determination.
Additional treatment options
Ketogenic Diet Therapy
Specialized high-fat, adequate protein, low-carbohydrate diet that may provide additional seizure control for some patients. Requires careful nutritional monitoring and supplementation to prevent deficiencies.
complementaryIntensive Neurorehabilitation Program
Comprehensive rehabilitation addressing motor, cognitive, and functional impairments from cortical malformations. Includes constraint-induced movement therapy, functional electrical stimulation, and gait training.
physical_therapyMultidisciplinary Seizure Monitoring Program
Long-term video-EEG monitoring combined with clinical assessment to characterize epilepsy syndrome, evaluate treatment response, and identify surgical candidates through detailed seizure analysis.
monitoringWhen to seek medical help
