ABSTRACT
Paroxysms of high-amplitude spike-waves or sharp waves recurring rhythmically on the occipital areas when the eyes are closed (POEC) are primarily observed in childhood epilepsy with occipital paroxysms (CEOP). An association of this electroencephalographic (EEG) pattern with idiopathic epilepsy has been disputed. We studied EEG and clinical features in 24 patients (age ranging from 3 to 25 years) with POEC. The EEG showed generalized discharges in 8 cases, rolandic spikes in 4 and background abnormalities in 4 cases. Eighteen (75%) patients manifested epileptic seizures. The nonfebrile seizures (16 cases) were partial (9 cases), generalized (6 cases) and unclassified (one patient). Two children had neurological examination or computed tomography abnormalities. Clinical and EEG data allowed for the following epileptic syndromes diagnosis CEOP, 7 cases; benign childhood epilepsy with centrotemporal spikes, one case; CEOP or benign childhood epilepsy with centrotemporal spikes, one case; partial symptomatic/cryptogenic epilepsy, 4 cases; generalized idiopathic, 2 cases; febrile convulsions, 2 cases. We conclude that POEC may be observed in cases with different types of idiopathic partial, cryptogenic/symptomatic and idiopathic generalized epilepsies and may also occur in patients with no seizures.
