CONTRIBUTO DELLA COMPUTED EEG TOPOGRAPHY (CET) ALLO STUDIO DELLE EPILESSIE INFANTILI

The data obtained by the use of Computed EEG Topography (CET) in a group of 65 epileptic children are reported. The paroxystic activity was evaluated by measuring the instant spatial distribution of the potentials ('amplitude maps'); the baseline EEG activity was studied by means of the spectrum analysis ('spectrum maps'). In the group of generalizes epilepsy (especially of symptomatic type) the CET technique ('spectrum maps') has pointed out a localised abnormality of the baseline EEG activity in two thirds of the cases; in the patients with partial epilepsy the 'spectrum maps' have proved to be particularly useful for localizing local areas of abnormality of the baseline EEG activity, in agreement with the clinical data (in 17 cases out of 40); both in the group of generalized epilepsy and in that of partial epilepsy, the 'spectrum maps' have been found to be more significant than the 'amplitude maps' of the paroxystic activity.
