Abstract:
Patients with medically refractory epilepsy, as defined by failure to achieve seizure freedom after adequate trials of 2 antiseizure medications, should be considered for early surgical evaluation. Achieving seizure freedom or meaningful seizure reduction, the goals of surgical treatment, can significantly improve quality of life while decreasing disease-related morbidity and mortality. Preoperative work up and imaging modalities aid in localization of epileptogenic zones that can be targeted in surgery. Resection of a seizure focus yields highest chances of seizure freedom; however, many promising minimally invasive or noninvasive treatment options have been developed in recent years that are closely intertwined with technological advancements and serve as viable alternatives to resection, particularly neuromodulation and ablation procedures. There are also new treatment options being developed and new neuromodulation targets being studied. Surgical treatment options should be thoughtfully selected based on each patient's individual disease process and preferences.
Insights
For medically refractory epilepsy, early surgical evaluation is recommended. Surgical interventions, including resection and newer minimally invasive options, aim for seizure freedom and improved quality of life.
Area of Science:
- Neurology
- Neurosurgery
Background:
- Medically refractory epilepsy affects quality of life and increases mortality.
- Early surgical evaluation is crucial for patients unresponsive to two antiseizure medications.
Purpose of the Study:
- To review current and emerging surgical and neuromodulation treatment options for medically refractory epilepsy.
- To emphasize individualized treatment selection based on patient factors.
Main Methods:
- Review of current literature on epilepsy surgery and neuromodulation.
- Discussion of diagnostic workup, including imaging for epileptogenic zone localization.
- Overview of surgical resection, minimally invasive ablation, and neuromodulation techniques.
Main Results:
- Epilepsy surgery offers the highest chance of seizure freedom.
- Minimally invasive and noninvasive options like neuromodulation and ablation are effective alternatives.
- Technological advancements are driving new treatment development.
Conclusions:
- Surgical evaluation should be considered early for refractory epilepsy.
