Patent ID: 8024032

Claim:
A method for detecting and quantifying an epileptic seizure in a subject, comprising the steps of: (a) receiving signals from a plurality of sensors indicative of brain state of a subject into a processor; (b) using the processor to estimate at least one Hurst parameter of the signals in moving time windows and a spatio-temporal propagation of the estimate of the at least one Hurst parameter of the signals in the moving time windows; (c) detecting an epileptic seizure by determining if a change in the spatio-temporal propagation of the estimate of the at least one Hurst parameter estimate is indicative of an epileptic seizure in the subject; and (d) determining if at least one feature of the detected epileptic seizure quantifies the seizure, wherein said feature is selected from a set consisting of duration, intensity, onset location, degree of spread, propagation path and speed through regions of the brain being monitored by the plurality of sensors.
