Introduction
The Lennox-Gastaut Syndrome (LGS) Market is an important part of the global rare neurological disorder therapeutics landscape. Lennox-Gastaut Syndrome is a severe form of epilepsy that typically begins in early childhood, characterized by multiple types of seizures, cognitive impairment, and resistance to standard antiepileptic treatments. The market is driven by increasing awareness of rare neurological disorders, advancements in antiepileptic drug development, and growing investments in gene therapy and precision medicine.
Rising prevalence rates, coupled with expanding clinical trials for novel therapeutic agents, are fostering growth across the global LGS treatment market. Despite being a rare disease, the burden of LGS is significant due to its complex clinical management and long-term healthcare requirements.
