Complex partial seizures of temporal lobe origin in children of different age groups
1Department of Epileptology, University of Bonn, Germany.
Insights
Temporal lobe seizures (TLS) present differently in young children compared to adults. This difference can complicate diagnosis and surgical planning for pediatric epilepsy surgery.
Area of Science:
- Neurology
- Pediatric Neurology
- Epileptology
Background:
- The semiology of complex partial seizures (CPS) of temporal lobe origin in adults is well-established and crucial for epilepsy surgery localization.
- However, the behavioral features of temporal lobe seizures (TLS) in children have been inconsistently described in existing literature.
Purpose of the Study:
- To investigate and compare the clinical semiology of temporal lobe seizures (TLS) in children with those observed in adults.
- To identify age-specific seizure manifestations in pediatric temporal lobe epilepsy.
Main Methods:
- Analysis of video recordings from 29 children (18 months to 16 years) with confirmed temporal lobe seizures.
- Inclusion criteria involved seizure freedom post-temporal lobectomy, clear unitemporal seizure onset on ictal EEG, unilateral radiological lesions, and corresponding histopathology.
Main Results:
- Children over 6 years old exhibited TLS semiology similar to adults.
- Younger children (< 6 years) displayed distinct features, including symmetric limb motor phenomena, frontal lobe seizure-like postures, and head nodding reminiscent of infantile spasms.
Conclusions:
- The clinical presentation of temporal lobe seizures in younger children can be misleading.
- These atypical semiological features necessitate cautious consideration during patient selection for temporal lobe epilepsy surgery in pediatric populations.
Abstract:
The semiology of complex partial seizures (CPS) of temporal lobe origin in adults is well known and is important in establishing seizure localization in patients considered for epilepsy surgery. In contrast, the behavioral features of temporal lobe seizures (TLS) in children described in the literature have not been consistent. In the present study, we investigated children with TLS to compare their attacks to TLS occurring in adults. The study was based on video recordings of 29 children with TLS aged 18 months to 16 years. Children were included, if they became seizure-free after temporal lobectomy (except 4 children with a marked reduction in seizure frequency and 1 with isolated auras), and if clear unitemporal seizure onset in ictal EEG-recordings, unilateral radiological lesions, and corresponding histopathological findings were detected. Children aged > 6 years had TLS with features similar to those of adults. In younger children, typical semiology included symmetric motor phenomena of the limbs, postures similar to frontal lobe seizures in adults, and head nodding as in infantile spasms. We concluded that the clinical features of TLS in younger children can be misleading and should therefore be considered with caution in selecting patients for surgical procedures on the temporal lobe.
