Insights
Perinatal adverse events and brain infections are the leading causes of drug-resistant epilepsy in children. Preventive measures, including improved perinatal and neonatal care, can reduce this burden.
Area of Science:
- Pediatric Neurology
- Epileptology
- Public Health
Background:
- Drug-resistant epilepsy affects 25-30% of children with epilepsy.
- Etiology of epilepsy varies geographically, with limited data from low-resource settings.
- Understanding regional causes is crucial for targeted interventions.
Purpose of the Study:
- To describe the clinical and etiologic profile of pediatric drug-resistant epilepsy.
- To identify region-specific concerns in a low-resource setting.
- To inform preventive strategies for drug-resistant epilepsy.
Main Methods:
- Retrospective chart review over 10 years (2011-2020).
- Inclusion of children aged 1 month to 18 years meeting International League Against Epilepsy (ILAE) criteria for drug-resistant epilepsy.
- Analysis of clinical data, perinatal history, EEG, MRI, and other evaluations.
Main Results:
- 593 children enrolled; 52.3% males.
- Most common seizure type: generalized (76.6%), particularly epileptic spasms (48.1%).
- Predominant etiologies: perinatal adverse events (e.g., asphyxia 37.9%) and infections; West syndrome (48%) and Lennox-Gastaut syndrome (6.2%) were common electroclinical syndromes.
Conclusions:
- Perinatal brain injury and infections are primary causes of pediatric drug-resistant epilepsy in this region.
- Improved perinatal care, institutional deliveries, and optimized neonatal care are vital.
- Vaccination against meningitis and Japanese B encephalitis can reduce the burden.
Abstract:
Purpose: Nearly 25% to 30% of children with epilepsy develop drug-resistant epilepsy. Etiology of epilepsy, including drug-resistant epilepsy, varies with geographical region. Identifying paucity of etiologic data on drug-resistant epilepsy from our region and similar low-resource settings, we aimed to describe the clinical and etiologic profile of children and adolescents with drug-resistant epilepsy, to better inform region-specific concerns. Methods: A chart-based retrospective review covering 10 years (January 2011-December 2020) was conducted. Participants between 1 months and 18 years of age who fulfilled International League Against Epilepsy (ILAE) definition of drug-resistant epilepsy were enrolled. Clinical details, perinatal history, electroencephalography (EEG), magnetic resonance imaging (MRI), and other evaluation-based data were analyzed. Results: Five hundred ninety-three children (52.3% males) were enrolled. The median age at presentation was 63 (interquartile range [IQR] 12-72) months and median age at onset was 12 (IQR 2-18) months. The most frequent seizure type was generalized (76.6%). Of these, epileptic spasms (48.1%) were most frequent. Focal seizures comprised 22.9%. The predominant contributor to etiology was perinatal adverse events, including perinatal asphyxia (37.9%), neonatal hypoglycemic brain injury (15.6%), and neonatal sepsis/meningitis. Electroclinical syndromes were observed in 361 (60.9%) children. Of these, the most frequent were West syndrome (48%) and Lennox-Gastaut syndrome (6.2%). Conclusion: Perinatal brain injury and brain infections were the most common causes of drug-resistant epilepsy identified. These findings indicate an opportunity for reducing the burden of pediatric drug-resistant epilepsy in our region by instituting preventive measures, including improved perinatal care, promotion of institutional deliveries, optimized obstetric and neonatal care, and immunization for vaccine-preventable infections such as bacterial meningitis and Japanese B encephalitis.
