MOOD CIRCUIT MONITORING TO CONTROL THERAPY DELIVERY
First Claim
1. A method comprising:
- monitoring a first brain signal of a patient at a first location within the brain of the patient;
monitoring a second brain signal at a second location within the brain, wherein the first and second locations are part of a common mood circuit of the brain;
determining a mood state metric indicative of a relationship between a first frequency band characteristic of the first brain signal and a second frequency band characteristic of the second brain signal; and
controlling delivery of therapy to the patient to control a psychiatric disorder based on the mood state metric.

Abstract
Brain signals may be monitored at different locations of a mood circuit in order to determine a mood state of the patient. A relationship (e.g., a ratio) between frequency band characteristics of the monitored brain signals may be indicative of a particular mood state. In some examples, therapy parameter values that define the therapy delivered to the patient may be selected to maintain a target relationship (e.g., a target ratio) between the frequency band characteristics of the brain signals monitored within the mood circuit. In addition, in some examples, therapy delivery to the patient may be controlled based on the frequency band characteristics of brain signals sensed at different portions of the mood circuit.

18. A medical system comprising:
-
a therapy module that delivers a psychiatric disorder therapy to a patient; a sensing module that monitors a first brain signal of a patient at a first location within the brain of the patient and monitors a second brain signal at a second location within the brain, wherein the first and second locations are part of a common mood circuit of the brain; and a processor that determines a mood state metric indicative of a relationship between a first frequency band characteristic of the first brain signal and a second frequency band characteristic of the second brain signal, and controls the therapy module based on the mood state metric. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
