Claim 0:
1. A method of seizure detection comprising:
receiving, by a processing circuit, an electroencephalogram (EEG) signal generated based on electrical brain activity of a patient;
determining, by the processing circuit, a plurality of metrics based on the EEG signal, the plurality of metrics indicating non-linear features of the EEG signal
performing, by the processing circuit, a preliminary analysis with one of the plurality of metrics, wherein the preliminary analysis indicates that the EEG signal is significant or that the EEG signal is insignificant, the one of the plurality of metrics is eigenvalues of the EEG signal, and the preliminary analysis comprising:
monitoring a moving window of eigenvalues of the EEG signal; and
determining whether the eigenvalues are decreasing;

responsive to a determination in the preliminary analysis that the eigenvalues are decreasing, performing, by the processing circuit, a secondary analysis with one or more other metrics of the plurality of metrics to determine whether the EEG signal indicates a candidate seizure or that the EEG signal is insignificant; and
generating, by the processing circuit, a seizure alert indicating that the EEG signal indicates the candidate seizure responsive to a determination in the secondary analysis that the EEG signal indicates the candidate seizure.
