1. A method comprising:

  • receiving data relating to a beat sequence of a patient'"'"'s heart;

    determining at least one regularity nonlinear analysis parameter associated with the beat sequence of the patient'"'"'s heart and at least one predictability nonlinear analysis parameter associated with the beat sequence of the patient'"'"'s heart;

    performing a first comparison of the at least one regularity nonlinear analysis parameter to a first adjustable threshold;

    performing a second comparison of the at least one predictability nonlinear analysis parameter to a second adjustable threshold;

    detecting an epilepsy event based on the first comparison and the second comparison, the epilepsy event comprising at least one of an unstable brain state, a brain state indicative of an elevated probability of a seizure, a brain state indicative of an impending seizure, and a seizure; and

    providing an output indicative of the epilepsy event.
