abstract

  • The EEG in childhood epilepsy with occipital paroxysms (CEOP) was termed "distinctive" by Gastaut (1985) and Talwar et al. (1992) and "characteristic" by Herranz Tanarro et al. (1984), which suggests that the EEG is specific and diagnostic for CEOP. However, this hypothesis has been challenged (Newton and Aicardi, 1983; Beaumanoir and Grandjean, 1987). To test this, we reviewed 5,291 EEG reports made in 5 1/2 years in the only tertiary pediatric center in Newfoundland and Labrador. We identified 31 children who had one or more EEGs with occipital spike/sharp waves showing suppression of discharges with eye opening and normal background activity. Six had CEOP, 17 had benign nocturnal childhood occipital epilepsy, 5 had symptomatic epilepsy, 3 had unusual complex partial seizures (CPS), 4 had only provoked seizures, and 2 had no definite seizures. Overlap between seizure types was common. The EEG criteria for CEOP are not very specific.
