[Electro-clinical semiology of subintrant temporal lobe seizures]

The authors recorded 10 to 67 TLS (mean 29) in 10 patients (5 M, 5 F; 9 to 41 years, mean 23) during 'acute' (4-6 hours) stereo-EEG exploration. At the onset of seizures, we observed: subjective manifestations (often epigastric), autonomic symptoms, and oro-alimentary 'automatisms'. Affective, unpleasant, manifestations occurred in only 2 patients. The discharges may only affect the Ammon's horn, but they never involve only the amygdala. There is a strong relationship between the duration of the discharge, the number of cerebral structures (temporal and, later, extratemporal) involved in the discharge, and the clinical symptomatology. Somatomotor lateralized manifestations, and gestural 'automatisms' only occur when the discharges spread to extratemporal cerebral structures. The secondary generalizations are very rare and are also linked to a large extratemporal spread of the discharge.
