West Syndrome Market Outlook

Thelansis’s “West Syndrome Market Outlook, Epidemiology, Competitive Landscape, and Market Forecast Report – 2024 To 2034" 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 West Syndrome treatment modalities options for eight major markets (USA, Germany, France, Italy, Spain, UK, Japan, and China).

West Syndrome Overview

West syndrome, also known as Infantile spasms, is a severe neurological disorder that affects infants and young children, characterized by early onset seizures, usually between 4-7 months of age, which can be flexor, extensor or flexor-extensor spasms, abnormal brain activity seen on an EEG and a poor prognosis for seizure control and intellectual development. The cause of West syndrome can be prenatal, perinatal, or postnatal. It can be classified as symptomatic groups that are considered the consequences of a known or suspected central nervous system disorder. Cryptogenic groups are presumed to be symptomatic, but the etiology is not known. Idiopathic forms, having no underlying cause other than a possible hereditary predisposition, are not recognized for West syndrome in the current International Classification. Other conditions that may be considered in the diagnosis of West syndrome include epilepsy with mental retardation, other epileptic and epileptiform encephalopathies, benign myoclonus of early infancy, and myoclonic-astatic epilepsy. The outlook for infants with West syndrome is poor, with only 14% of infants with symptomatic West syndrome having normal or borderline-normal cognitive development compared with 28-50% of infants with idiopathic infantile spasms. Some factors such as idiopathic or cryptogenic etiology, the onset of seizures after four months, absence of atypical spasms and partial seizures, absence of asymmetrical EEG abnormalities, early treatment, and an excellent response to treatment can predict a more favourable outcome. Infants with symptomatic infantile spasms are more likely to develop autism spectrum disorders than those with cryptogenic or idiopathic spasms. Steroids and anti-seizure medications are the most commonly used treatments, with the steroid ACTH sometimes being injected into the muscles.
