Insights
Suppressing interictal discharges improved behavior in children with epilepsy, especially those with partial epilepsy. This suggests a link between brain electrical activity and behavioral issues in pediatric epilepsy.
Area of Science:
- Pediatric Neurology
- Epilepsy Research
- Behavioral Neuroscience
Background:
- Current treatment for childhood epilepsy focuses on clinical seizures.
- The role of subclinical epileptic activity (interictal discharges) in behavior is not fully understood.
Purpose of the Study:
- To investigate if reducing interictal discharges impacts behavior in children with epilepsy.
- To explore the relationship between electroencephalographic (EEG) discharge suppression and behavioral improvements.
Main Methods:
- A double-blinded, placebo-controlled, crossover study involving 61 children with mild or well-controlled epilepsy.
- Patients received either lamotrigine then placebo, or placebo then lamotrigine, with EEG monitoring and behavioral assessments.
- The study assessed if reduced EEG discharges correlated with improved behavioral scores.
Main Results:
- Behavioral ratings significantly improved in children whose interictal discharge frequency or duration decreased with active treatment.
- No behavioral improvement was observed in children without a significant change in discharge rate.
- Improvements were most pronounced in children with partial epilepsy.
Conclusions:
- Reducing interictal epileptic discharges can lead to behavioral improvements in children with epilepsy, particularly those with partial epilepsy.
- Focal epileptic discharges may play a role in the mechanisms underlying behavioral problems associated with epilepsy.
Objectives:
It is generally agreed that children should be treated for epilepsy only if they have clinical seizures. The aim of this study was to examine whether suppressing interictal discharges can affect behavior in children with epilepsy.
Study Design:
In a double-blinded, placebo-controlled, crossover study, 61 children with well-controlled or mild epilepsy were randomly assigned to add-on therapy with either lamotrigine followed by placebo or placebo followed by lamotrigine. Ambulatory electroencephalographic recordings and behavioral scales were performed during baseline and at the end of placebo and drug phases. The primary hypothesis to be tested was that behavioral scales would improve specifically in patients with a reduction of electroencephalographic discharges during active drug treatment.
Results:
Global rating of behavior significantly improved only in patients who showed a significant reduction in either frequency ( P < .05) or duration of discharges ( P < .05) during active treatment but not in patients with without a significant change in discharge rate. This improvement was mainly seen in patients with partial epilepsy ( P < .005).
Conclusions:
Our data suggest that suppressing interictal discharges can improve behavior in children with epilepsy and behavioral problems, particularly partial epilepsy. Focal discharges may be involved in the underlying mechanisms of behavioral problems in epilepsy.
