1. A method of treating a nervous system disorder in a patient, the method comprising:

  • sensing a brain signal from the patient;

    obtaining a neurological event detection signal, the neurological event detection signal indicating neurological events detected from the brain signal;

    sensing a cardiac signal from the patient;

    obtaining a cardiac event detection signal, the cardiac event detection signal indicating cardiac events detected from the cardiac signal;

    analyzing timing relationships between detected events, the detected events including detected neurological events and detected cardiac events;

    identifying a matched event when one of the detected neurological events is temporally related to one of the detected cardiac events;

    determining whether the cardiac event detection signal facilitates detection of neurological events based on matched events;

    delivering a therapy to the patient for treating the neurological disorder in response to a cardiac event if the cardiac event detection signal is determined to facilitate detection of neurological events; and

    changing the therapy delivered to the patient based on the brain signal.
