Infantile epileptic spasm syndrome (IESS) is an age-dependent epileptic encephalopathy that onset within 3 ~ 12 months. Commonly used Anti-seizure medications (ASMs) have poor efficacy, low long-term control rate and high recurrence rate, and often leave behind sequelae such as developmental delay/intellectual disability, and autism spectrum disorders. At present, the first-line recommended treatments for IESS are Adrenocorticotropic hormone (ACTH), adrenocortical hormone and vigabatrin. If ineffective, other ASMs, ketogenic diets, and surgical treatments can be tried. This article will provide a review of the current status and related clinical applications of IESS treatment.
