Seizure Detection and Prediction Algorithms

Research in automatic analysis of EEG for supporting the diagnosis of epileptic seizures took pace in the 1970s. Prior et al [45] suggested the use of a device called cerebral function monitor to demarcate generalized tonic-clonic seizures. These could be identified as a large increase in EEG amplitude followed by an observable decrease and by large EMG activity. Method described by Ives et al [46] involved filtering of 16 channel EEG and amplitude discrimination. Though, it could detect large seizure discharge it was not sensitive to smaller discharges. Babb et al [47] introduced an electronic circuit that could recognize a seizure through a rapid succession of large amplitude spikes.
