Systems and methods for enhancing or affecting neural stimulation efficiency and/or efficacy
First Claim
1. A method of treating Parkinson'"'"'s disease (PD) in a patient, the method comprising:
- receiving one or more signals from a patient-controller input device that is indicative of self-administration of Levodopa or other dopamine agonist;
in response to the receiving, communicating one or more signals by the patient-controller input device to an implantable pulse generator to initiate a pre-defined stimulation protocol to accommodate for metabolization of the administered Levodopa or dopamine agonist, wherein the pre-defined stimulation protocol comprises;
(a) applying a first stimulation program after a first time delay, the first stimulation program including stimulation parameters selected to provide an optimal stimulation therapy after a drug-onset time of the administered Levodopa or dopamine agonist;
(b) applying a second stimulation program after a second time delay, the second stimulation program including stimulation parameters selected to provide an optimal stimulation therapy for a drug half-life of the administered Levodopa or dopamine agonist; and
(c) applying a third stimulation program after a third time delay, the third stimulation program including stimulation parameters selected to provide an optimal stimulation therapy for drug level substantially below a level expected for the drug half-life of the administered Levodopa or dopamine agonist;
wherein the applying the first, second, and third stimulation programs occurs automatically by the implantable pulse generator implanted in the patient in response to the implantable pulse generator receiving the one or more signals from the patient-controller input device.

Abstract
Systems and methods for enhancing or affecting neural stimulation efficiency and/or efficacy are disclosed. In one embodiment, a system and/or method may apply electromagnetic stimulation to a patient'"'"'s nervous system over a first time domain according to a first set of stimulation parameters, and over a second time domain according to a second set of stimulation parameters. The first and second time domains may be sequential, simultaneous, or nested. Stimulation parameters may vary in accordance with one or more types of duty cycle, amplitude, pulse repetition frequency, pulse width, spatiotemporal, and/or polarity variations. Stimulation may be applied at subthreshold, threshold, and/or suprathreshold levels in one or more periodic, aperiodic (e.g., chaotic), and/or pseudo-random manners. In some embodiments stimulation may comprise a burst pattern having an interburst frequency corresponding to an intrinsic brainwave frequency, and regular and/or varying intraburst stimulation parameters. Stimulation signals providing reduced power consumption with at least adequate symptomatic relief may be applied prior to moderate or significant power source depletion.
