Abstract:
Epilepsy is the most prevalent disabling neurological disorder across the life span, and is not controlled by medications in more than one-third of patients. Epilepsy surgery is an accepted treatment, with guidelines supporting utilization in patients with recurrent temporal lobe seizures after two or more trials of antiepileptic medications. Unfortunately, the average delay in presurgical evaluation of appropriate candidates is more than 20 years, and this delay has not improved in recent decades. This offers the international neurological community the opportunity to improve disability, mortality, and quality of life by more effective application of epilepsy surgery and earlier identification of potential candidates. Optimal use of MRI and video/EEG monitoring should allow cost-effective screening of persons with recurrent seizures prior to more detailed presurgical evaluation when indicated.
Insights
Epilepsy surgery can improve outcomes for patients with drug-resistant epilepsy. Earlier presurgical evaluation is crucial to reduce delays and improve quality of life for those with recurrent seizures.
Area of Science:
- Neurology
- Neurosurgery
- Epileptology
Background:
- Epilepsy is a leading cause of neurological disability.
- Over one-third of epilepsy cases are refractory to medication.
- Epilepsy surgery is an established treatment for refractory epilepsy.
Purpose of the Study:
- To highlight the significant delay in epilepsy surgery evaluations.
- To advocate for earlier identification of surgical candidates.
- To improve patient outcomes and quality of life.
Main Methods:
- Review of current guidelines for epilepsy surgery.
- Analysis of delays in presurgical evaluation.
- Discussion of optimal screening tools like MRI and video/EEG monitoring.
Main Results:
- Average delay for presurgical evaluation exceeds 20 years.
- This delay has remained stagnant over decades.
- Cost-effective screening can identify candidates earlier.
Conclusions:
- Earlier application of epilepsy surgery can reduce disability and mortality.
- Optimizing MRI and video/EEG monitoring can facilitate timely evaluations.
- Improved surgical candidate identification is a key opportunity for the neurological community.

Seizures: Classification
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:
