1. A method for comparing a brain signal to a cardiac signal for use in detecting neurological events, the method comprising:
- receiving a brain signal with a medical device system comprising processing circuitry for a period of time;
receiving a cardiac signal with the medical device system for a period of time;
obtaining information with the processing circuitry identifying one or more neurological events in the brain signal;
obtaining information with the processing circuitry identifying one or more cardiac events in the cardiac signal; and
comparing the brain signal and the cardiac signal with the processing circuitry to determine a temporal relationship between the one or more neurological events and the one or more cardiac events for determining whether neurological event detection is improved by using the cardiac signal, the comparing comprisingcategorizing with the processing circuitry each of the identified neurological events as cardiac matched when there is a cardiac event within a specified time period of the neurological event; and
computing with the processing circuitry a rate of concordance between the neurological events and the cardiac events based on the number of cardiac matched events and the number of neurological events.

Abstract
A medical device system that includes a brain monitoring element, cardiac monitoring element and a processor. The processor is configured to receive a brain signal from the brain monitoring element and a cardiac signal from the cardiac monitoring element. The processor is further configured to compare the brain signal to the cardiac signal. A method of comparing a brain signal to a cardiac signal is also provided.
