Filed:

Jun 10, 1999

Appl. No.:

09/329593

Inventors:

Ivan Osorio - Leawood KS
Mark Frei - Lawrence KS
David Lerner - Lawrence KS
John Ralston - Lawrence KS
Josef Dorfmeister - Lawrence KS

Assignee:

University of Kansas - Lawrence KS

International Classification:

A61B 504

US Classification:

600544, 600300, 600545

Abstract:

A system ( ) analyzes signals representative of a subjects brain activity in a signal processor ( ) for information indicating the subjects current activity state and for predicting a change in the activity state. One preferred embodiment uses a combination of nonlinear filtering methods to perform real-time analysis of the electro-encephalogram (EEG) or electro-corticogram (ECoG) signals from a subject patient for information indicative of or predictive of a seizure, and to complete the needed analysis at least before clinical seizure onset. The preferred system then performs an output task for prevention or abatement of the seizure, or for recording pertinent data.

Abstract:

A system () analyzes signals representative of a subject's brain activity in a signal processor () for information indicating the subject's current activity state and for predicting a change in the activity state. One preferred embodiment uses a combination of nonlinear filtering methods to perform real-time analysis of the electro-encephalogram (EEG) or electro-corticogram (ECoG) signals from a subject patient for information indicative of or predictive of a seizure, and to complete the needed analysis at least before clinical seizure onset.
