Video EEG outcome on children referred following a single unprovoked afebrile seizure.

RESULTS A total of 998 vEEGs were undertaken during the study period. Of these, 128 were following a fi rst afebrile seizure: 119/128 were referred by general paediatricians and the remaining 9 by paediatric neurologists. The mean age group was 6.5 years (range 1 month to 17 years). Thirty-four of 128 children had an underlying neurodevelopmental problem. In 11 children, there was a family history of epilepsy and in 13 a past history of febrile convulsions. The seizure semiology included generalised tonic clonic seizure (n=50), focal (n=25), atonic (n=4), myoclonic (n=2) and uncertain (n=47). The vEEG outcomes were normal (n=75), non-epileptic events recorded (n=8) and suggestive of an epilepsy syndrome (n=45). The breakdown of the 45 patients with an epilepsy syndrome was idiopathic generalised epilepsy (n=14), focal epilepsies (n=29) and generalised epilepsy with febrile seizures+ (n=2). The syndromes suggested in the 14 patients with idiopathic generalised epilepsy were juvenile absence epilepsy (n=1), juvenile myoclonic epilepsy (n=1) and idiopathic generalised epilepsy not otherwise specifi ed (n=12). Of the 29 with EEGs suggestive of focal epilepsies, focal idiopathic epilepsy accounted for 25/29 (benign rolandic (n=10), late-onset occipital epilepsy (n=2), early-onset occipital epilepsy (n=2) and others (n=11)) and focal symptomatic epilepsy accounted for 4/29.
