Medical Eponyms
Dravet Syndrome (1978)

Dravet Syndrome: clinical term for early onset epileptic encephalopathy (EIEE) characterized by generalized tonic, clonic, and tonic-clonic seizures that are initially induced by fever and begin during the first year of life. [aka Severe Myoclonic epilepsy of infancy (SMEI), Early Infantile Epileptic Encephalopathy-6 (EIEE6), OMIM 607208]

Mutations occur in the SCN1A gene in around 70-80% of patients and are not normally associated with familial inheritance, however family history of a febrile seizure is part of diagnostic criteria.  It is incredibly rare.   Symptom onset is associated with raised body temperature, with triggers including vaccination, hot baths and fever.

Affected children show initially normal development, which becomes delayed following onset of seizure activity, which is not limited to one form.  Progression of the disease leads to motor symptoms, including ataxia and dysarthria, cognitive impairment and visual perception difficulties.  Behaviour changes are also often seen, such as aggression.

Treatment is challenging, due to seizures not being responsive to anti-epileptic therapy and there are high childhood mortality rates.  Due to the pathophysiology of the disease, common epileptic medications targeting the sodium channel may also worsen symptoms.  Brain and nerve stimulation therapies have been found to be useful in some cases. 

History

1978 Initially described by Dravet in 1978, as Severe Myoclonic Epilepsy of Infancy (SMEI) to distinguish it from the Lennox-Gastaut syndrome (LGS).

1989 Name change to Dravet syndrome as part of a report by ILAE including the classification of 8 epileptic encephalopathy syndromes

Febrile and afebrile generalized and unilateral, clonic or tonic–clonic, seizures, that occur in the first year of life in an otherwise normal infant and are later associated with myoclonus, atypical absences, and partial seizures. All seizure types are resistant to antiepileptic drugs (AEDs). Developmental delay becomes apparent within the second year of life and is followed by definite cognitive impairment and personality disorders

Commission on Classification and Terminology ILAE; 1989

2001 Mutation in the SCN1A gene was found in the majority of patients, leading it to be termed an epileptic encephalopathy.
