Detecting, quantifying, and/or classifying seizures using multimodal data
First Claim
1. A method, comprising:
- receiving at least one of a signal relating to a first cardiac activity from a patient and a signal relating to a first body movement from the patient;
deriving at least one patient index from said at least one received signal;
triggering at least one of a test of the patient'"'"'s responsiveness, a test of the patient'"'"'s awareness, a test of a second cardiac activity of the patient, a test of a second body movement of the patient, a spectral analysis test of a second cardiac activity of the patient, and a spectral analysis test of the second body movement of the patient, based on said at least one patient index;
determining an occurrence of an epileptic event based at least in part on said one or more triggered tests; and
performing a further action in response to said determination of said occurrence of said epileptic event.

Abstract
A method, comprising receiving at least one of a signal relating to a first cardiac activity and a signal relating to a first body movement from a patient; triggering at least one of a test of the patient'"'"'s responsiveness, awareness, a second cardiac activity, a second body movement, a spectral analysis test of the second cardiac activity, and a spectral analysis test of the second body movement, based on at least one of the signal relating to the first cardiac activity and the signal relating to the first body movement; determining an occurrence of an epileptic event based at least in part on said one or more triggered tests; and performing a further action in response to said determination of said occurrence of said epileptic event. Further methods allow classification of epileptic events. Apparatus and systems capable of implementing the method.

21. A computer-readable storage device for storing instructions that, when executed by a processor, perform a method, comprising:
-
receiving at least one of a signal relating to a first cardiac activity from a patient and a signal relating to a first body movement from the patient; triggering at least one of a test of the patient'"'"'s responsiveness, a test of the patient'"'"'s awareness, a test of a second cardiac activity of the patient, a test of a second body movement of the patient, a spectral analysis test of a second cardiac activity of the patient, and a spectral analysis test of the second body movement of the patient, based on at least one of the signal relating to the first cardiac activity and the patient'"'"'s signal relating to the first body movement; determining an occurrence of an epileptic event based at least in part on said one or more triggered tests; and performing a further action in response to said determination of said occurrence of said epileptic event.

22. A system, comprising:
-
at least one sensor configured to receive at least one of a signal relating to a first cardiac activity from a patient, a signal relating to a first body movement from the patient, a responsiveness signal from the patient, an awareness signal from the patient, a signal relating to a second cardiac activity of the patient, and a signal relating to a second body movement of the patient; a detection unit configured to receive said at least one signal from said at least one sensor and determine an occurrence of an epileptic event; and an action unit configured to receive an indication of said occurrence of said epileptic event from said detection unit and perform at least one of logging the occurrence and/or time of occurrence of the epileptic event;
providing a warning, alarm or alert to the patient, a caregiver or a health care provider;
providing a therapy to prevent, abort, and/or reduce the severity of the epileptic event;
assessing one or more patient parameters such as awareness or responsiveness during the epileptic event;
assessing the severity of the epileptic event, identifying the end of the epileptic event; and
assessing the patient'"'"'s post-ictal impairment or recovery from the epileptic event. - View Dependent Claims (23)
