Complex partial seizures of temporal lobe origin in children of different age groups.
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.
