US 2025/0359813 A1 · SYSTEM AND METHOD OF DETECTING ELECTROPHYSIOLOGICAL EVENTS IN A SUBJECT

Abstract

A system and method of detecting Electrophysiological events such as Interictal Epileptiform Discharge (IED) events, or other pathological and physiological electrophysiological events, in a human subject by at least one processor may include, for example: placing at least one first electroencephalogram (EEG) electrode over a zygomatic bone or a maxilla of the subject, directly below the subject's orbit in the subject's inferior direction; receiving a first EEG signal from the at least one first EEG electrode; processing the first EEG signal, to obtain one or more first EEG data elements; and inferring at least one machine-learning (ML) based model on the one or more first EEG data elements, to predict occurrence of at least one IED event in the subject.

Dependent claims

A method of detecting Electrophysiological (EP) events in a human subject by at least one processor, the method comprising:

obtaining at least one extracranial signal from at least one respective extracranial electroencephalogram (EEG) electrode, placed at a predetermined position over a zygomatic bone or a maxilla of the subject;
processing the at least one extracranial signal, to obtain one or more extracranial data elements;
and
inferring at least one machine-learning (ML) based, EP detection model on the one or more extracranial data elements, to detect occurrence of at least one EP event in the extracranial signal.

1 more element

A system for detecting EP events in a human subject, the system comprising:

an EEG device, coupled with one or more EEG electrodes;
a non-transitory memory device, wherein modules of instruction code are stored;
and
at least one processor associated with the memory device, and configured to execute the modules of instruction code,
whereupon execution of said modules of instruction code, the at least one processor is configured to:
obtain, via the EEG device at least one extracranial signal from at least one respective extracranial EEG electrode, placed at a predetermined position over a zygomatic bone or a maxilla of the subject, directly below the subject's orbit in the subject's inferior direction;
process the at least one extracranial signal, to obtain one or more extracranial data elements;
and
infer at least one ML based, EP detection model on the one or more extracranial data elements, to detect occurrence of at least one EP event in the extracranial signal.
