Question: What is Dravet syndrome?

Context:
Dravet syndrome is one of the most severe epilepsy syndromes of early childhood, and it comes with very high morbidity and mortality. The typical presentation is characterized by hemiclonic or generalized clonic seizures triggered by fever during the first year of life, followed by myoclonic, absence, focal and generalized tonic-clonic seizures.
BACKGROUND: Dravet syndrome is a severe form of epilepsy.
Dravet syndrome, a severe infantile epilepsy syndrome, is typically resistant to anti-epileptic drugs (AED).
Dravet syndrome is an epilepsy syndrome of infantile onset, frequently caused by SCN1A mutations or deletions.
Dravet syndrome is an epileptic encephalopathy characterized by multiple types of seizures.
Haploinsufficiency of the voltage-gated sodium channel Nav1.1 causes Dravet syndrome, an intractable childhood-onset epilepsy with hyperactivity, cognitive deficit, autistic-like behaviours, and premature death
Thus, the multi-faceted phenotypes of Dravet syndrome can be genetically dissected, revealing synergy in causing epilepsy, premature death and deficits in long-term spatial memory, but interneuron-specific effects on hyperactivity and autistic-like behaviours
Dravet syndrome, or as it was called in the past severe myoclonic epilepsy in infancy, is a drug-resistant epilepsy first described by Charlotte Dravet in 1978
Dravet syndrome is a severe form of epilepsy.
Severe myoclonic epilepsy in infants (SMEI), also known as Dravet syndrome, is a rare, refractory form of epilepsy, for whose treatment stiripentol (STP) has been recently licensed for add-on use.To evaluate the efficacy and tolerability of STP and other antiepileptic drug treatments (including ketogenic diet) as therapy for patients with SMEI.We searched the Cochrane Epilepsy Group Specialised Register (15 May 2013), the Cochrane Central Register of Controlled Trials (CENTRAL, Issue 4 of 12, The Cochrane Library, April 2013), MEDLINE (1
Dravet syndrome is a severe infantile-onset epileptic encephalopathy associated with mutations in the sodium channel alpha-1 subunit gene SCN1A.
Dravet syndrome is a rare form of epilepsy largely refractory to current antiepileptic medications. 
Dravet syndrome is a rare epileptic encephalopathy characterized by treatment-resistant polymorphic seizures. 
Dravet syndrome is a severe form of epileptic encephalopathy characterized by early onset epileptic seizures followed by ataxia and cognitive decline.
Dravet syndrome is a severe form of intractable pediatric epilepsy with a high incidence of SUDEP: Sudden Unexpected Death in epilepsy. 
Dravet syndrome or severe myoclonic epilepsy of infancy (SMEI) is a baleful epileptic encephalopathy that begins in the first year of life. 
Dravet syndrome is a severe infantile onset epilepsy syndrome with multiple seizure types, developmental slowing and poor outcome
Dravet syndrome is an intractable epileptic syndrome beginning in the first year of life.
Dravet syndrome is an epileptic syndrome of infancy and early childhood.
Dravet syndrome is an epileptic syndrome of infancy.
patients with severe myoclonic epilepsy of infancy (Dravet's syndrome)
Dravet syndrome is a severe infantile epileptic encephalopathy caused in approximately 80% of cases by mutations in the voltage gated sodium channel subunit gene SCN1A

Answer: Dravet syndrome is one of the most severe epilepsy syndromes of early childhood, and it comes with very high morbidity and mortality. It is likely that Dravet syndrome is underdiagnosed in adults with treatment-resistant epilepsy.
