Insights
Ambulatory electroencephalogram (aEEG) aids in diagnosing epilepsy in children. Prioritizing patients with frequent events improves the diagnostic yield of this valuable tool for seizure classification.
Area of Science:
- Pediatric Neurology
- Clinical Neurophysiology
Background:
- Ambulatory electroencephalogram (aEEG) is crucial for distinguishing epileptic seizures from nonepileptic events.
- It aids in assessing seizure frequency and classifying seizure types in pediatric patients.
Purpose of the Study:
- To evaluate the clinical utility of aEEG in a pediatric population.
- To determine the diagnostic yield of aEEG in children referred for evaluation of episodic events.
Main Methods:
- Prospective study of 100 children (aged 11 days to 16 years) referred for aEEG.
- Clinical data and aEEG recordings were collected and analyzed.
Main Results:
- aEEG contributed to a clinical diagnosis in 71% of referred children.
- Epileptic disorders were confirmed by ictal recordings in 26% of cases.
- This included 11 children with previously normal conventional EEG.
Conclusions:
- aEEG is a clinically useful diagnostic tool in pediatric epilepsy evaluation.
- Recommending telephone checks for current event frequency can optimize aEEG recording of typical events.
Abstract:
Ambulatory electroencephalogram has been used for differentiating epileptic from nonepileptic events, recording seizure frequency and classification of seizure type. We studied 100 consecutive children prospectively aged 11 days to 16 years that were referred for an ambulatory electroencephalogram to a regional children's hospital. Ambulatory electroencephalogram was clinically useful in contributing to a clinical diagnosis in 71% of children who were referred with a range of clinical questions. A diagnosis of epileptic disorder was confirmed by obtaining an ictal record in 26% and this included 11 children that had previously normal awake and or sleep electroencephalogram. We recommend making a telephone check of the current target event frequency and prioritising those with typical events on most days in order to improve the frequency of recording a typical attack.
