Pediatric-Onset Multiple Sclerosis (POMS) and Epilepsy: Exploring Etiological Complexity-Outcomes 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. : Although multiple sclerosis is primarily recognized as an adult-onset disease, its occurrence in children presents distinctive challenges, especially related to seizure disorders. : We reviewed 120 pediatric MS patients evaluated over 7 years; six of these (5%) experienced seizures (including one case of acute status epilepticus), and five were diagnosed with epilepsy according to the latest International League Against Epilepsy (ILAE) classification. This study aimed to evaluate the occurrence rates and types of seizures while investigating their management strategies in this specific group. : Through a 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 ( < 0.006). The analysis recognized early MS onset and highly active disease types as further risk factors that led to worse health outcomes. : Genetic causes of epilepsy in children are common and may interact 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 comorbid with MS among pediatric patients, seeking to facilitate the creation of improved interdisciplinary clinical practices in pediatric neurology.
