At the time, Dravet and her colleagues proposed a list of diagnostic criteria for SMEI, which included a family history of epilepsy and seizures that begin before age 1 and are of the febrile, clonic (convulsive) type. Typical absence seizures and epileptic spasms are unusual. Delay can range from mild (rare) to moderate/severe (common), and most adult patients are dependent on caregivers (Catarino 2011). Dravet syndrome is associated with a mutation in the SCN1A gene in 80-90% of cases (Rosander 2015). The life expectancy of people who suffer from syndrome of Dravet is uncertain. 1 INTRODUCTION. DS is considered an epileptic encephalopathy, or disorder of the brain due to seizures. JOURNAL ARTICLES de Lange IM, Koudijs MJ, van ‘t Slot R, Gunning B, Sonsma ACM, van Gemert LJJM, Mulder F, Carbo EC, van Kempen MJA, Verbeek NE, Nijman IJ, Ernst RF, Savelberg SMC, Knoers NVAM, Brilstra EH, Koeleman BPC.

Dravet syndrome is a rare form of epilepsy that typically begins in the first year of life and is marked by frequent, often prolonged seizures in the early phases. Adult patients suffer multiple co-mordities in addition to the seizures, including but not limited to cognitive disabilities, behavioral challenges, decreased mobility, sleep issues, and gastrointestinal issues. Dravet syndrome patients are more prone status epilepticus, which is when there is a long lasting seizure or when seizures occur close together without recovery between them.

In 2018, Epidiolex (cannabidiol or CBD) was approved by the U.S. Food and Drug Administration (FDA) to treat seizures associated with Dravet syndrome in patients two years of age and older. Severe myoclonic epilepsy of infancy (SMEI) was first described by C. Dravet (1978) as a well‐characterized condition. It is a more accurate way of expressing mortality than simple percentages because it takes time into account.) Other genes have been associated with DS including SCN2A, SCN8A, GABRA1, GABARG2, PCDH19, STXBP1, and SCN1B, but the clinical presentation in these cases is often somewhat atypical of DS (Wirrell 2017). Before 1989, this syndrome was known as epilepsy with polymorphic seizures, polymorphic epilepsy in infancy (PMEI), or severe myoclonic epilepsy in infancy (SMEI).
