[Epilepsy and other convulsive states in long-term EEG monitoring].

The authors report the results of EEG monitoring lasting many hours with cassette recording and with interpretation after reproduction on monitor screen. The Medilog 9000 System Oxford was used for that purpose. The group comprised 32 verified cases of epilepsy and 19 cases of seizures with unestablished aetiology. In epileptics the method made possible determination of the actual frequency of seizures and their clinico electroencephalographic qualification. In the remaining group of 18 patients the epileptic character of their seizures was demonstrated in 3 cases, in 9 cases the mechanism of these seizures varied, sometimes they were neurotic vasovagal. In 6 cases the monitoring failed to provide sufficient data. These results demonstrate a highly usefulness of cassette EEG monitoring in neurological practice, especially in case of seizures. A valuable supplementation of these investigations are records monitored by television, which make possible establishing of a more close correlation between clinical symptoms and EEG findings.
