Surgery for Drug-Resistant Epilepsy in Children

Area of Science:

• Neurology
• Pediatric Epilepsy
• Neurosurgery

Background:

• Drug-resistant epilepsy affects children and adolescents, necessitating alternative treatments.
• Randomized trials are crucial for evaluating neurosurgical interventions in pediatric epilepsy.

Purpose of the Study:

• To assess the efficacy of neurosurgical treatment versus medical therapy alone in drug-resistant epilepsy in young patients.
• To compare seizure freedom, seizure severity, cognitive function, social quotient, behavior, and quality of life between surgical and medical treatment groups.

Main Methods:

• A single-center randomized trial involving 116 patients (≤18 years) with drug-resistant epilepsy.
• Patients were assigned to either epilepsy surgery plus medical therapy or medical therapy alone (control group).
• Primary outcome was seizure freedom at 12 months; secondary outcomes included various clinical and quality-of-life assessments.

Main Results:

• Epilepsy surgery resulted in significantly higher seizure freedom rates (77% vs. 7%) at 12 months (P<0.001).
• Surgery group showed significant improvements in seizure severity, behavior, quality of life, and social quotient compared to the medical therapy group.
• No significant difference was observed in intelligence quotient between the groups.

Conclusions:

• Neurosurgical treatment offers a significant benefit for children and adolescents with drug-resistant epilepsy.
• Epilepsy surgery improves seizure control, behavior, and quality of life, though associated with neurological deficits.
• Further randomized trials are warranted to solidify these findings and guide clinical practice.
