1. A system for identification of an increased risk of a severe neurological event, comprising:

  • an electroencephalogram (EEG) monitoring unit configured to receive EEG data generated by one or more EEG sensors adapted to sense neurological activity of a patient during at least a postictal phase of each of one or more seizures; and

    a processing unit configured to;

    receive the EEG data from the EEG monitoring unit;

    detect a plurality of postictal EEG suppression periods interleaved with postictal EEG non-suppression periods during each of at least one postictal phase of the one or more seizures from the EEG data, wherein a postictal EEG suppression period is detected when the EEG data crosses an EEG threshold for at least a predetermined time period;

    detect a first trend of generally increasing duration with time of the plurality of postictal EEG suppression periods during the postictal phase of one or more seizures; and

    identify the increased risk of the severe neurological event based on the first trend.
