[EEG in offspring of epileptic mothers]
Insights
Children born to mothers with epilepsy have a higher risk of abnormal electroencephalogram (EEG) findings and seizures. These EEG abnormalities are more common in older children and those whose mothers had early-onset epilepsy.
Area of Science:
- Neurology
- Pediatrics
- Clinical Neurophysiology
Context:
- Epilepsy in mothers poses potential risks to offspring.
- Understanding the long-term neurological impact on children is crucial.
Purpose:
- To investigate the prevalence and characteristics of electroencephalogram (EEG) abnormalities in children of mothers with epilepsy.
- To identify risk factors associated with these neurological changes.
Summary:
- Abnormal EEG tracings were observed in 39.6% of 134 children of epileptic mothers, with 5.2% experiencing seizures.
- Paroxysmal dysrhythmia characterized EEG changes, more frequent in children aged 5-14 and those whose mothers had epilepsy before age 20.
- Pathological EEG findings were more prevalent in daughters, with generalized centrencephalic discharges noted significantly more often.
Impact:
- Highlights the increased risk of neurological abnormalities in offspring of epileptic mothers.
- Suggests genetic or environmental factors may influence EEG development in these children.
- Informs potential screening and monitoring strategies for at-risk pediatric populations.
Abstract:
In a group of 134 children of epileptic mothers abnormal EEG tracings were found in 39.6% of cases, 7 of these children (5.2%) had epileptic seizures. In 92% of cases EEG changes had the character of paroxysmal dysrythmia, and they were significantly more frequent in children aged 5 to 14 years and significantly more frequent in the children of mothers who had had epilepsy before the age of 20 years. Pathological EEG changes were more frequent in daughters than in sons, and in the daughters generalized discharges of centrencephalic type were significantly more frequent. In all families with more than two children at least one child had pathological EEG tracings.
