1. A method of detecting a neurological event following delivery of stimulation therapy, the method comprising: initializing a post-stimulation detection counter, C, to an initial value, C 0 ; acquiring a stream of EEG signal data values following delivery of stimulation therapy; comparing the signal data values to a level cutoff; decrementing C by a decrement amount if a given data value is below the level cutoff; incrementing C by an increment amount if a given data value is equal to or exceeds the level cutoff; comparing C to a post-stimulation detection threshold, PS th ; and detecting a neurological event if C equals or exceeds PS th .
