In 1978, Charlotte Dravet described the cryptogenic epilepsy syndrome severe myoclonic epilepsy of infancy (SMEI) (Dravet, 1978
). This severe generalized epileptic encephalopathy begins at around 6 months of age with febrile hemiclonic or generalized status epilepticus. Hemiclonic status typically recurs involving each side independently. After 1 year of age, other seizure types appear including absence, partial, atonic and often myoclonic seizures. Early development is normal, with slowing and regression after 1 to 2 years; pyramidal features and ataxia may also evolve. The prognosis is poor. The recent draft proposal of the ILAE classification suggests the eponymous name Dravet syndrome instead of SMEI
