Exploring the Connection: Seizures and Epilepsy in Children with Multiple Sclerosis – Insights from a Single Center Experience

This article examines the complex relationship between seizures, epilepsy, and multiple sclerosis (MS) in pediatric patients, based on detailed findings from a single-center study. Background : Although multiple sclerosis is primarily recognized as an adult-onset disease, its occurrence in children presents distinctive challenges, especially related to seizure disorders. Methods : We reviewed 120 pediatric MS patients evaluated over 7 years; 6 of these (5%) experienced seizures (including one case of acute status epilepticus), and 5 were diagnosed with epilepsy according to the latest ILAE classification. This study aims to evaluate the occurrence rates and types of seizures while investigating their management strategies in this specific group. Results: Through detailed case analysis and patient follow-up, we identified key factors contributing to seizure onset and explored implications for treatment and care. In our cohort, children with MS and seizures showed a higher risk for disease progression and greater cumulative disability, evidenced by a significantly higher last Expanded Disability Status Scale (EDSS) score (after a minimum 2-year follow-up) in the seizure group (p < 0.006). The analysis recognized early MS onset and highly active disease types as further risk factors that led to worse health outcomes. Conclusions: Genetic causes of epilepsy in children are common and may interplay with MS-related inflammation in the same patient; our observations underscore the need to investigate how these two conditions interact. This work contributes to the broader understanding of epilepsy comorbidity with MS among pediatric patients, to facilitate the creation of improved interdisciplinary clinical practices in pediatric neurology.
