Electroclinical correlations in temporal lobe epilepsy.

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).

Clinical, computerized EEG and polysomnographical studies in some myoclonic syndromes.

Forty-two patients with myoclonic manifestations (especially during subacute sclerosing panencephalitis (SSPE)) were studied. The multidimensional investigations pointed out that myoclonias produce several EEG and polysomnographical perturbations: 1. Sleep disorganization; 2. Appearance of the myoclonic jerks in wakefulness (especially) and in some sleep stages; 3. Some electroclinical discordances; 4. A great variability of the myoclonias during some sleep stages; 5. EEG cortical mappings showed individual variabilities of Radermecker complexes.

Polysomnographical researches in patients with temporal lobe epilepsy.

One hundred and twelve patients with temporal lobe epilepsy were studied. Continuous polysomnographical recordings were performed for eight hours, the patients being video-monitored all the time. These researches, completed with computerized EEG cortical mappings demonstrated a peculiar activation of the temporal foci during REM phases and during some stages of LSWS.
