[Application of ambulatory cassette EEG system to the polysomnography in childhood epilepsy].
Using an ambulatory cassette EEG system (Oxford Medilog 9000), polysomnography was performed in 25 cases of children with epilepsy and 25 normal children. The results revealed decreases in REM sleep and REM density in intractable epilepsy. An increase of slow waves was observed during REM sleep in severe myoclonic epilepsy in infancy or its adjacent group, and this result was more clearly demonstrated by an EEG auto analysis with fast Fourier transform. This above ambulatory cassette EEG system will be utilized more easily for polysomnography, and contribute to the research not only of the pathophysiology of epilepsy but also of the sleep mechanism itself.
