The rare seizure type infantile spasms is frequently part of the infantile epileptic spasm syndrome (IESS, previously named ‘West syndrome’), which is an epileptic encephalopathy with a high risk of drug-resistant epilepsy [1]. Seizure onset occurs at age 3-12(24) months and the majority of children develop a severe neurodevelopmental outcome [1]. IESS can be associated with multiple aetiologies, including structural brain abnormalities, hypoxic-ischemic encephalopathy, neurogenetic and neurometabolic diseases [2].
