Insights
Ictal emotional expressions (EEs) in children are common and differ from adults. Positive EEs indicate extratemporal or right-sided seizure origins, unlike negative EEs.
Area of Science:
- Pediatric Neurology
- Epilepsy Research
- Clinical Neurophysiology
Background:
- Ictal emotional expressions (EEs) are observed in epilepsy.
- Previous studies primarily focused on adult populations.
- Understanding EEs in children is crucial for accurate localization.
Purpose of the Study:
- To analyze the lateralizing and localizing value of ictal emotional expressions (EEs) in children.
- To compare these findings with existing adult epilepsy studies.
Main Methods:
- Systematic analysis of 514 seizures from 100 children (<=12 years) with partial epilepsy.
- Video recordings reviewed by blinded investigators.
- Categorization of EEs into positive (smile, happiness, laughing) and negative (fear, crying, pain) groups.
Main Results:
- Emotional expressions occurred in 35% of pediatric patients.
- EEs were more frequent in extratemporal (49%) than temporal (26%) lobe seizures.
- Positive EEs showed extratemporal dominance and right-sided lateralization; negative EEs did not localize or lateralize.
Conclusions:
- Ictal emotional expressions are frequent in childhood epilepsy.
- Their localizing and lateralizing properties differ significantly from those observed in adults.
- This study provides novel insights into pediatric epilepsy localization.
Objective:
To systematically analyze the lateralizing and localizing value of ictal emotional expressions (EEs) in children and compare these results with those of earlier adult studies.
Methods:
Five hundred fourteen seizures of 100 consecutive children < or = 12 years with partial (61/100 temporal lobe) epilepsy and postoperative seizure free outcome were included in the study. Video recordings of seizures were reviewed by two independent investigators blinded to the patients' clinical data.
Results:
Thirty-five patients produced EE at least once during their archived seizures, including fear (15), crying (12), smile (9), pain (5), happiness (3), and laughing (in one case). Emotional symptoms were divided into two groups: positive (smile, laughing, and happiness) and negative EEs (fear, crying, and pain). Emotional expressions appeared more frequently during extratemporal (49%) than temporal (26%) lobe seizures (p < 0.05). Positive EEs had an extratemporal dominance (p < 0.05), while frequency of negative EEs did not localize the seizure onset zone. Assessing their lateralizing value, positive EEs were more frequent during right-sided seizures (p < 0.05) while negative EEs did not lateralize the seizure onset zone. Frequency of EEs were independent of patients' ages, age at epilepsy onset or duration of epilepsy.
Conclusion:
This is the first comprehensive childhood study showing that ictal EEs are frequent in childhood and their localizing and lateralizing properties are different from those of adults.
