From syndrome to precision therapy: current and emerging therapeutic options for selected pediatric focal epilepsies

Pediatric focal epilepsies comprise a heterogeneous group of disorders, ranging from self-limited childhood syndromes to severe drug-resistant forms associated with structural, genetic, immune, or unknown etiologies. Despite newer antiseizure medications, pediatric evidence remains largely extrapolated from heterogeneous focal-onset seizure trials, with limited syndrome- or localization-specific data.

A structured iterative narrative search of PubMed, Scopus, and Embase was completed in May 2026 and supplemented by section-specific searches and manual reference screening. This review summarizes current and emerging pharmacotherapeutic options for selected representative pediatric focal epilepsies using a syndrome- and localization-oriented approach. We discuss self-limited focal epilepsies of childhood, frontal lobe epilepsy, and temporal lobe epilepsy, highlighting conventional antiseizure medications, newer agents, and investigational or repurposed treatments. Particular attention is given to drug resistance, comorbidities, rational polytherapy, and integration of pharmacological treatment with genetic diagnosis, neuroimaging, and surgical evaluation.

Management is moving from a purely seizure-based approach toward individualized, mechanism-informed care. Newer antiseizure medications expand therapeutic options, particularly in drug-resistant focal epilepsies, but should not delay etiological work-up or timely referral for epilepsy surgery. Future progress will require pediatric condition-specific trials, genotype-driven stratification, real-world data, and targeted therapies.
