1. A method for the detection of seizures comprising the steps of:
- (i) acquiring a first bioelectric signal and a second bioelectric signal of a human subject;
(ii) processing the first of bioelectric signals to define a cognitive state of mind window for the subject;
(iii) processing the second bioelectric signal to define a moving cognitive state of mind window for the subject; and
(iv) comparing the baseline EEG window with the moving EEG window to define a dynamical similarity index indicative of the likelihood of a seizure.

Abstract
A method and system for the detection and prevention of epileptic seizures utilizing bioelectric signals to assess a seizure profile (SP) and an adaptive control system for neurofeedback therapy. The inventive method and system provide the detection of changes in the non-linear dynamics of brain electrical activities to characterize and differentiate individual susceptibility to seizure onset, predict the occurrence of a seizure episode, and initiate neurofeedback training to prevent the attack.

16. A system for the detection of brain electrical activity for the predicting and preventing seizures of a human subject, comprising:
-
(i) signal acquisition means for acquiring a first set of bioelectric signals and a second set of bioelectric signals of a human subject, and (ii) a computer means in communication with the signal acquisition means for processing the bioelectric signals to define a baseline cognitive state of mind and a moving state of mind and to compare the baseline and the moving states of mind for determining a dynamical similarity index (DSI) indicative of the likelihood of a seizure of the subject. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
