Abstract:
1. A method of predicting a seizure event, the method comprising: acquiring an electroencephalograph (EEG) signal and extracting one or more EEG features; acquiring a cardiovascular (CV) signal and extracting one or more CV features; comparing at least one of the EEG and CV features to one or more features extracted from a reference seizure to form at least one similarity measure; comparing at least one of the EEG and CV features to one or more features extracted from a reference baseline to form at least one dissimilarity measure; deriving a discriminant measure, the discriminant measure being a function of the at least one similarity measure and the at least one dissimilarity measure; comparing the discriminant measure to a predetermined threshold; and predicting a seizure event when the discriminant measure exceeds the predetermined threshold.
