Methods, systems and apparatuses for detecting increased risk of sudden death

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

• an electroencephalogram (“EEG”) monitoring unit configured to collect EEG data from the patient's brain during at least a postictal phase of one or more seizures;
• a processing unit configured to receive the EEG data from the EEG monitoring unit, the processing unit configured to detect postictal EEG suppression from the EEG data when the EEG data crosses an EEG threshold for at least a predetermined time period;
• a respiratory monitoring unit configured to collect respiratory data from the patient's respiration during at least the postictal phase of the one or more seizures in response to detection of the postictal EEG suppression, wherein the processing unit configured to receive the respiratory data from the respiratory monitoring unit and to determine whether the respiratory data crosses a respiratory threshold;
• and
• an electrocardiogram (“EKG”) monitoring unit configured to collect EKG data for the patient's heart, wherein the processing unit is configured to receive the EKG data from the EKG monitoring unit and to determine whether the EKG data crosses an EKG threshold, wherein the processing unit is configured to determine whether the EKG data crosses the EKG threshold in response to a determination that the respiration data crosses the respiration threshold;
• wherein the processing unit configured to identify the increased risk of the severe neurological event based on the detected postictal EEG suppression, the determination that the respiration data crosses the respiration threshold, and the determination that the EKG data crosses the EKG threshold.
