2,698 epileptic patients were studied, 2,019 cases (64.3%) presenting temporal lobe epileptic attacks. Besides the routine EEG recordings and the corroboration of the clinical data with the meticulous observations by video monitoring on a closed circuit TV-screen (the patients being observe in a specially arranged room, provided with infra-red cameras), the diagnostic procedure was supported in all cases by several computerized EEG mappings, according to a model achieved by us, transcribing the primary data obtained by Hjorth's NSD parameters from the Siemens-Elema Mingograph to a Romanian M-118 microprocessor. In many cases we utilized an interface--built by us--for analog-digital conversion which allowed the direct introduction and conversion of amplitudes and frequencies from the Mingograph to the micro-computer. These were isolated to analyse the following electroclinical forms: 1. temporal absences: 360 cases (17.8%); 2. psychomotor attacks: 439 cases (21.7%) 3. psychosensory attacks: 77 cases (3.8%); 4. attacks with cognitive symptomatology: 260 cases (12.8%); 5. crises with ideative-affective symptomatology: 76 cases (3.8%); 6. vegetative attacks: 51 cases (2.5%); 7. akinetic attacks: 89 cases (4.4%); 8. focal temporal attacks secondarily generalized: 667 cases (33.0%). In 112 patients with nocturnal attacks, polysomnographic recordings were performed with sequential computerized EEG mappings during the various stages of sleep (concomitantly with the infrared video-TV monitoring).
