title: [Epilepsy with centro-temporal spikes and parietal spikes: comparative study].
abstract: There are controversies about the existence of a benign parietal epilepsy distinct from the benign partial epilepsy with centro-temporal spikes. We studied 164 children with no neurological or neuroradiological evidence of brain damage and with epilepsy and spikes restricted to the centro-temporal (CTS) or to the parietal regions (PS). The subject's age, age at onset and type of seizures and the presence of spikes evoked by consecutive taps applied to both hands and feet were compared between 111 patients with CTS and 53 patients with PS. Age of patients and age at onset of seizures predominated until 6 years in the PS group and after 6 years in the CTS group. The occurrence of oropharyngeal or facial motor seizures was statistically more frequent among the patients with CTS (44.1%) as opposed to PS group (16.9%). In 39.5% of the children with PS and only in 3.5% of those with CTS, the EEG showed high voltage potentials, similar to the habitual spikes in clinical EEG, evoked by the stimulation of one or both feet or hands. Our findings suggest that in neurologically normal children with epilepsy, the group with PS differs from those with CTS in the age, age at onset and type of seizures and EEG reactivity to percussion of hands and feet.
