Method and apparatus for event-triggered reinforcement of a favorable brain state
First Claim
1. A method of potentiating a brain state of a patient, comprising:
- monitoring one or more brain signals in an area of the brain of the patient;
detecting an episode of a brain state based on the one or more brain signals, the brain state associated with a decrease in one or more symptoms of a brain condition of the patient; and
delivering to the monitored area of the brain electrical stimulation that potentiates the brain state in response to the detection of the brain state episode, the electrical stimulation delivered within a window of time that extends no greater than 250 milliseconds from occurrence of the brain state episode, wherein monitoring, detecting, and delivering are each performed at least in part by control circuitry of a medical device.

Abstract
Methods and apparatuses are disclosed for potentiating a favorable brain state that is associated with relief in symptoms of a brain condition. Techniques include monitoring one or more brain signals and detecting an episode of a favorable brain state based on the one or more brain signals, the favorable brain state associated with a decrease in one or more symptoms of a brain condition of the patient. Then, in response to the detection of the favorable brain state episode, electrical stimulation that potentiates the favorable brain state is delivered to the brain of the patient, the electrical stimulation delivered within a window of time opened for detection of each favorable brain state episode.

15. A system comprising:
-
One or more sensors configured to receive from an area of the brain of a patient one or more signals indicative of brain activity of the patient; A stimulation generator configured to generate and deliver electrical stimulation to the area of the brain of the patient, wherein the electrical stimulation potentiates a brain state of the patient; and control circuitry configured to detect a brain state episode based on the one or more signals and control delivery of the electrical stimulation within a window of time that extends no greater than 250 milliseconds from occurrence of the brain state episode in response to the detection of the brain state episode, the brain state associated with a decrease in one or more symptoms of a brain condition of the patient. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
