[Use of 24-hour casette monitoring of the EEG recording in the differential diagnosis of attacks of unconsciousness in adults].

24-hour cassette recording of EEG using the Medilog 9000 system was done in 36 patients referred for observations because of diagnostic difficulties in cases of refractors unconsciousness attacks. The method made possible isolation of 3 groups: 1. 6 patients with attacks not suggestive of epilepsy 2. 12 patients with false unconsciousness attacks which were in fact short partial complex seizures (temporal lobe absence) 3. 17 patients with actual unconsciousness attacks. The study demonstrated a high usefulness of 24-hour EEG monitoring in the differential diagnosis of unconsciousness attacks increasing the likelihood of attack recording and making possible their precise clinical and EEG characteristics which is often impossible with routine EEG and history taking.
