Promising therapeutic strategies for Lennox-Gastaut syndrome: what's new?

INTRODUCTION

The seizures in Lennox-Gastaut syndrome are typically resistant to treatment. Seven antiseizure medications (ASMs) in the US (six in the UK/EU) are licensed for the treatment of seizures in LGS: lamotrigine, topiramate, rufinamide, clobazam, felbamate (not licensed in the UK/EU), cannabidiol and fenfluramine. Other options include neurostimulation, corpus callosotomy and dietary therapies, principally the ketogenic diet and its variants. New treatments and therapeutic strategies are needed to improve management of both seizures and cognitive/behavioral comorbidities in LGS.

AREAS COVERED

Embase and Medline were searched for articles published between 1 January 2014 and 21 August 2024 reporting efficacy data for pharmacological, neurostimulation, surgical and dietary interventions in individuals with LGS focusing on recent advances. Ongoing and prospective studies were identified from the National Library of Medicine register of clinical trials.

EXPERT OPINION

LGS remains a difficult-to-treat epilepsy. Although no major breakthroughs have been reported, several established and novel ASMs, some surgical strategies and other treatment approaches are of benefit or are showing promise. Progress remains incremental but any improvements in the management of this resistant epilepsy syndrome are worthwhile.
