TABLE 1.
Clinical presentation: in a developmentally normal child, who presents with seizures of unknown cause (normal magnetic resonance imaging, normal laboratory studies, ± normal cerebrospinal fluid studies), genetic testing to exclude DS should be performed with the following seizure types
Seizure | Age 2–5 months | Age 6–15 months | ||||
---|---|---|---|---|---|---|
Without fever | With fever | After vaccination | Without fever | With fever | After vaccination | |
Single seizure | ||||||
Prolonged (5–29 min) GTCS | 63% a | 74% b | 74% b | 63% a | 58% a | 68% b |
Prolonged (5–29 min) hemiclonic seizure | 68% b | 84% c | 95% c | 68% b | 84% c | 89% c |
Focal or generalized convulsive status epilepticus (≥30 min) | 74% b | 84% c | 89% c | 74% b | 84% c | 89% c |
Recurrent seizures | ||||||
Recurrent brief (<5 min) convulsive seizures | 63% a | 58% a | 58% a | 58% a | ||
Recurrent brief (<5 min) hemiclonic seizures | 68% b | 74% b | 79% b | 79% b | ||
Recurrent prolonged focal or generalized convulsive seizures (5–29 min) | 89% c | 100% c | 84% c | 95% c | ||
Recurrent focal or generalized convulsive status epilepticus (≥30 min) | 89% c | 95% c | 89% c | 95% c |
Based on 19 physician responses.
Abbreviations: DS, Dravet syndrome; GTCS, generalized tonic–clonic seizure.
Responses indicate no consensus for genetic testing for DS.
Responses indicate Moderate consensus for genetic testing for DS.
Responses indicate Strong consensus for genetic testing for DS.
