Lennox-Gastaut Syndrome (LGS) Market Outlook

Thelansis’s “Lennox-Gastaut Syndrome (LGS) Market Outlook, Epidemiology, Competitive Landscape, and Market Forecast Report – 2021 To 2032" covers disease overview, epidemiology, drug utilization, prescription share analysis, competitive landscape, clinical practice, regulatory landscape, patient share, market uptake, market forecast, and key market insights under the potential Lennox-Gastaut Syndrome treatment modalities options for eight major markets (USA, Germany, France, Italy, Spain, UK, Japan, and China).

Lennox-Gastaut Syndrome (LGS) Overview

Lennox-Gastaut syndrome (LGS) is a rare and severe form of childhood epilepsy, falling into the category of severe infantile epileptic syndromes, which includes epileptic neonatal encephalopathy with suppression-burst, West syndrome and severe myoclonic epilepsy of infancy. Typically, LGS manifests with seizures starting in early childhood, typically between ages 3 and 5. It is characterized by significant physical risks for affected children and teenagers, including frequent falls, injuries, and cognitive impairment, severely impacting their quality of life. While LGS may affect children with infantile spasms or underlying brain issues, it can also have an unknown cause (idiopathic). Almost always, antecedent conditions linked to LGS involve the cerebral cortex, with phenomena of LGS stemming from the cerebral cortex and corpus callosum. LGS is most commonly associated with damage to both frontal lobes. However, any brain damage can potentially lead to LGS, and the lack of specificity complicates understanding its neurophysiological mechanisms. Individuals with LGS, including children, adolescents, and adults, experience various types of seizures that vary from person to person. These include:

  1. Body stiffening, upward eye gaze, dilated pupils, and altered breathing patterns characterize tonic seizures.
  2. Atypical absences, which involve staring spells.
  3. Atonic seizures result in a brief loss of muscle tone and potential abrupt falls.
  4. Myoclonic seizures cause sudden muscle jerks.
  5. Generalized tonic-clonic seizures are marked by muscle stiffness and rhythmic jerking.

In addition to medications approved for general seizure treatment, there are specific drugs approved for managing seizures in individuals with LGS, such as clobazam, rufinamide, topiramate, lamotrigine, felbamate, cannabidiol, fenfluramine, and clonazepam.

  • The incidence of Lennox-Gastaut syndrome is extremely low, accounting for approximately 1% of childhood epilepsies in children under 10 years old. The majority of LGS cases, around 68%, occur in children under 18, with the remaining 38% affecting adults. Notably, remission rates are particularly low for LGS, with roughly 50-60% of children who initially experience infantile spasms going on to develop other types of seizures.
