“…As previously reported, TLE in childhood is not rare and can be recognized correctly even in very young children (Jayakar and Duchowni, 1990; Wyllie et al, 1993; Bye and Foo, 1994; Brockhaus and Elger, 1995; Harvey et al, 1997; Rathgeb et al, 1998; Broglin, 2001; Franceschetti et al, 2001; Pachatz et al, 2001; Fogarasi et al, 2002; Franzon et al, 2004; Ray and Kotagal, 2005). In our population, age at onset was < 6 years in 82% and < 3 years in 51% of cases.…”

Summary:Purpose: Temporal lobe epilepsy (TLE) is probably more difficult to recognize in children than in adults. In fact, ictal symptoms in children are less stereotyped and less obvious, and the neuropathological substrate is more heterogeneous than in adults. The aim of this study is to examine the relationships between etiology, age at onset and electroclinical findings in 77 children with TLE, 32 of whom were surgically treated.Methods: Electroclinical study including video-EEG recording of seizures in 77 children with TLE. The investigation focused on the first five initial ictal symptoms.Results: Age at onset was less than 3 years in 39 cases, between 3 and 6 years in 17 cases and older than 6 years in 21 cases. Auras also occurred in younger children but were more common after the age of 6 years. A peculiar initial ictal semiology consisted in staring with arrest, lip cyanosis, and very slight oral automatisms.In some cases, EEG recordings documented seizures starting independently on both temporal lobes. Based on electroclinical and neuroradiological features, we recognized three subgroups: symptomatic TLE due to cortical malformations or nonevolutive tumors, TLE with mesial temporal sclerosis, and cryptogenic TLE.Conclusions: A correct electroclinical and neuroradiological approach allows in several cases early recognition of TLE even when onset is earlier than the age of 6 years. A correct definition of the localization relies primarily on video-EEG recording of the seizures, possibly repeated during follow up in cases lacking obvious neuroradiological correlation.

“…In children, however, the clinical features of temporal lobe seizures (TLS) are controversial. Most reports on CPS in children have included cases of extratemporal as well as temporal seizure origin (11)(12)(13)(14)(15)(16)(17)(18)(19).…”

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.

“…In previous studies of seizure classification in infants based solely on symptoms, we (2,3) and other authors (4–10) noted a common seizure type characterized mainly by decreased behavioral activity with indeterminate level of consciousness. These have been called hypomotor (2,3) or behavioral/motion arrest (6,8–10) seizures.…”

“…In previous studies (2)(3)(4)(5)(6)(8)(9)(10)16,(21)(22)(23)(24)(25) of temporal lobe epilepsy in children, an age-related evolution of symptoms has been noted. Fine motor automatisms first appear in the preschool age (4,5,22), whereas automatisms in infants with temporal lobe epilepsy are usually limited to oral or simple gestural movements (2,6,9,10,16,24). We also noted an age-related trend in the current study, with hypomotor seizures seen most often in our youngest patients younger than 1 or 2 years.…”

Summary:Purpose: Hypomotor seizures (characterized by diminished behavioral activity with indeterminate level of consciousness) have been identified as an important seizure type in infants. Our goal was to investigate further the clinical and EEG features of hypomotor seizures.Methods: We retrospectively reviewed 110 hypomotor seizures from 34 patients recorded with video-EEG.Results: Twenty-seven (79%) patients were younger than 48 months, and seven (21%) were aged 4 to 15 years. Seventy-one (64%) seizures had regional or lateralized EEG onset, arising predominantly from temporal or parietal lobe regions. The other 39 (35%) seizures had generalized onset, usually with abrupt onset of diffuse rhythmic high-amplitude theta activity or diffuse electrodecrement and only rarely (two patients) with slow spike-wave complexes or 3-Hz spike-wave complexes. Hypomotor seizures with generalized EEG onset were significantly shorter than those with regional or lateralized onset (p ‫ס‬ 0.01, GEE model). Unsustained head or eye movements and subtle mouth automatisms were commonly seen in hypomotor seizures with either focal or generalized onset. Seventeen percent of hypomotor seizures with focal onset evolved to include version of head and eyes or jerking of one arm, whereas 2% of generalized hypomotor seizures evolved to a cluster of spasms.Conclusions: Hypomotor seizures may be either focal or generalized. Regional EEG onsets were most often temporal or parietal, suggesting that focal hypomotor seizures may be a bland form of "complex partial" seizures with no or minimal automatisms, seen predominantly in infants. Generalized hypomotor seizures were rarely associated with an ictal pattern of generalized spike-wave complexes, suggesting a different mechanism from absence seizures seen later in life.
