OBJECTIVE To assess the long-term recurrence risks after a first unprovoked seizure in childhood. METHODS In a prospective study, 407 children who presented with a first unprovoked seizure were then followed for a mean of 6.3 years from the time of first seizure. RESULTS One hundred seventy-one children (42%) experienced subsequent seizures. The(More)
In a prospective study, antiepileptic drugs were discontinued in 264 children with epilepsy after a mean seizure-free interval of 2.9 years. They were then followed for a mean of 58 months to ascertain whether seizures recurred. Seizures recurred in 95 (36%) of the children. Etiology was a significant predictor of outcome (relative risk [RR] = 1.81). On(More)
In a prospective study, 283 children who presented with a first unprovoked seizure were followed for a mean of 30 months from the time of first seizure. Subsequent seizures were experienced by 101 children (36%). The cumulative risk of seizure recurrence for the entire study group was 26% at 12 months, 36% at 24 months, 40% at 36 months, and 42% at 48(More)
We examined EEG findings from an ongoing study of 347 children with a first unprovoked seizure. EEGs were available in 321 (93%), and 135 (42%) had an abnormal EEG. EEG abnormalities included focal spikes (n = 77), generalized spike and wave discharges (n = 28), slowing (n = 43), and nonspecific abnormalities (n = 7). Abnormal EEGs were more common in(More)
Focal electroencephalographic discharges in lesions of cortex induced by freezing are associated with prolonged membrane depolarizations and hyperpolarizations in neurons located at various depths in the lesion sites. Transmembrane potential changes have properties similar to those of postsynaptic potentials. The temporal relationship between intracellular(More)
