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.
