[Occipital spike-wave with and without benign epilepsy in the child]
Insights
This study identifies a specific electroencephalogram (EEG) pattern in children with benign occipital epilepsy. Phenobarbital therapy showed a good prognosis for most children with this functional childhood epilepsy.
Area of Science:
- Neurology
- Pediatric Neurology
- Epileptology
Context:
- Electroencephalogram (EEG) findings in childhood epilepsy.
- Specific EEG patterns associated with occipital lobe epilepsy.
- Clinical presentation and prognosis of childhood epilepsy.
Purpose:
- To describe a specific EEG pattern observed in 31 children.
- To correlate EEG findings with clinical manifestations and treatment outcomes.
- To evaluate the prognosis of this epilepsy subtype under phenobarbital therapy.
Summary:
- Thirty-one children presented with high-amplitude, variable-frequency spike-and-wave discharges in the occipito-postero-temporal regions on EEG, primarily with eyes closed.
- A functional temporo-rolandic spike-wave focus was noted in 13 cases. Clinically, 10 children were seizure-free, with 4 experiencing febrile convulsions and 17 treated for various partial and generalized seizures.
- Phenobarbital therapy demonstrated a good prognosis in nearly all cases of this functional, benign occipital epilepsy, which is related to childhood epilepsy with rolandic paroxysms.
Impact:
- Highlights a distinct EEG signature for a subset of childhood epilepsy.
- Suggests a favorable prognosis for benign occipital epilepsy with appropriate treatment.
- Provides insights into the relationship between occipital and rolandic epilepsy syndromes in children.
Abstract:
We describe 31 children with runs of high amplitude and variable frequency spike-and-wave discharges on the occipito-postero-temporal regions at the EEG. This characteristic EEG pattern can be seen on the posterior areas of one or both hemispheres only when the eyes are closed. A functional spike-wave focus of temporo-rolandic localization also occurred in 13 cases. Clinically, 10 children were seizure-free with minimal brain dysfunction in 8 of them. Of these, only 4 patients suffered from febrile convulsions while the 17 other patients were undergoing treatment for visual, motor or vegetative partial seizures, and even generalized fits. The prognosis of this essentially functional childhood epilepsy was good under phenobarbital therapy in almost all of our cases. This benign occipital epilepsy is related to childhood epilepsy with rolandic paroxysms.
