REMOTE CONTINUOUS SEIZURE MONITOR AND ALARM
First Claim
1. A system for monitoring and providing an alarm indicating that a threshold level of epileptiform activity has been exceeded in the brain of a subject, comprising:
- a headset comprising from 1 to 12 electroencephalogram (EEG) electrodes for collecting electrical activity from the brain of the subject;
b) a portable base unit in communication with the plurality of EEG electrodes, the base unit comprising;
a processor comprising computer-executable instructions for acting on data received from said plurality of EEG electrodes, the actions consisting essentially of;
(i) filtering, conditioning and analyzing a digital input generated from electrical signals collected by the plurality of EEG electrodes and transmitted from the headset to identify whether a predetermined epileptiform activity level has been exceeded;
(ii) generating an alarm signal when the predetermined epileptiform activity level has been exceeded;
(iii) time stamping and storing the digital signal when an alarm signal has been generated, thereby producing a record, wherein the record does not include unprocessed data of electrical brain activity; and
a memory for storage of the record; and
c) an alarm output in communication with the base unit for receiving the alarm signal and generating an alarm.

Abstract
An electroencephalogram (EEG) utilizing epileptiform activity detection, warning and recording system adapted for use by non-healthcare professionals or healthcare professionals. The system is simple enough for use by untrained personnel and will be self-contained, not requiring technical setup or point of use maintenance. The system includes a small number of passive or active scalp electrodes for capturing the electrical signals in the subject'"'"'s brain allowing for detection of epileptiform activity. The system will recognize epileptiform activity and will either transmit signals upon detection of epileptiform activity to either a localized warning device or to a cellular or radio receiving device. The system will note epileptiform activity in a recording component and allow for review of the epileptiform data to allow non-clinical and clinical personnel to verify such activity.

19. A method for monitoring and providing an alarm indicating that a threshold level of epileptiform activity has been exceeded in the brain of a subject, comprising:
a) collecting and responding to epileptiform data received from the subject'"'"'s brain by electroencephalogram (EEG) electrodes, the collecting and responding to steps consisting essentially of; i) collecting electrical activity from the brain of the subject via a headset comprising a plurality of 1 to 12 electrodes; i) filtering, conditioning and analyzing a digital input generated from electrical signals collected by the plurality of EEG electrodes and transmitted from the headset to identify whether a predetermined epileptiform activity level has been exceeded; iii) generating an alarm signal when the predetermined epileptiform activity level has been exceeded; iv) time stamping and storing the digital signal to a data storage device when an alarm signal has been generated, thereby producing a record, wherein the record does not include unprocessed data of electrical brain activity; and v) transmitting the alarm signal to an alarm output to generate an alarm. - View Dependent Claims (20, 21, 22)
