Insights
For children with therapy-resistant epilepsy, generalized tonic seizures are common. Effective long-term seizure control was achieved in 27 patients by reducing antiepileptic drug regimens.
Area of Science:
- Pediatric Neurology
- Epileptology
- Clinical Pharmacology
Background:
- Epilepsy affects many children, with therapy-resistant cases posing significant challenges.
- Generalized tonic seizures are a prevalent seizure type in pediatric generalized epilepsy.
Purpose of the Study:
- To investigate long-term seizure control in children with therapy-resistant generalized tonic seizures.
- To identify effective antiepileptic drugs and treatment strategies for this patient group.
Main Methods:
- Retrospective analysis of 362 children with therapy-resistant epilepsy.
- Focus on 119 patients with generalized tonic seizures.
- Long-term follow-up to assess seizure control and treatment efficacy.
Main Results:
- Complete seizure control for over 5 years was achieved in 27 patients.
- Effective antiepileptic drugs included Valproic Acid (VPA), Phenytoin (PHT), Clonazepam (CLB), and Zonisamide (ZNS), often in combination.
- A significant reduction in the average number of antiepileptic drugs from 4.7 to 2.4 was associated with seizure improvement.
Conclusions:
- Long-term seizure remission is achievable in a subset of children with therapy-resistant generalized tonic seizures.
- Optimizing antiepileptic drug regimens, including reducing drug load, is crucial for effective management.
- Specific antiepileptic drugs show efficacy in controlling these challenging seizures.
Abstract:
Of 362 children with therapy-resistant epilepsy, 119 patients had generalized tonic seizures, which were the most common seizure type in patients with generalized epilepsy. The long-term observation of the patients with tonic seizures revealed that their seizures were completely controlled in 27 patients for more than 5 years. The effective antiepileptic drugs were VPA (10 patients), PHT (5), CLB (4), ZNS (2), VPA + PHT (4), ZNS + CLB (1) and VPA + AZA (1). For obtaining improvement of tonic seizures, another strong factor is reducing the number of antiepileptic drugs, such as the average number of drugs, which was 4.7 to 2.4 in these 27 patients.
