Abstract

Neurostimulation systems and methods for providing therapy to a patient suffering from a symptom of a disease that latently responds to electrical stimulation therapy are provided. First electrical stimulation energy is conveyed to or from a tissue region of the patient in accordance with a first set of stimulation parameters, thereby affecting the symptom. A predetermined period of time estimated for the symptom to resolve in response to electrical stimulation therapy is allowed to elapse. Second electrical stimulation energy is conveyed to or from the tissue region in accordance with a second set of stimulation parameters different from the first set of stimulation parameters.

Claims

1. A neurostimulation system for use with a patient suffering from a symptom of a disease that latently responds to electrical stimulation therapy, comprising:

at least one electrical terminal to which at least one electrode can be coupled;

output stimulation circuitry coupled to the at least one electrical terminal;

memory storing a plurality of predetermined periods of time estimated for a plurality of symptoms to resolve in response to electrical stimulation therapy; and

control circuitry configured for allowing selection of one of the predetermined periods of time, controlling the output stimulation circuitry to convey first electrical stimulation energy to or from the at least one electrical terminal in accordance with a first set of stimulation parameters, waiting the selected predetermined period of time, and conveying second electrical stimulation energy to or from the tissue region in accordance with a second set of stimulation parameters different from the first set of stimulation parameters.

2. The neurostimulation system of claim 1, further comprising processing circuitry configured for evaluating the effect that the first electrical stimulation energy has on the symptom after waiting selected predetermined period of time.

3. The neurostimulation system of claim 2, wherein the processing circuitry is further configured for defining the second set of stimulation parameters based on the evaluation.

4. The neurostimulation system of claim 2, wherein the processing circuitry is further configured for determining that the symptom did not resolve in response to the first electrical stimulation energy after waiting the selected predetermined period of time, wherein the second electrical stimulation energy is conveyed in response to the determination that the symptom did not resolve.

5. The neurostimulation system of claim 1, wherein at least one of the predetermined periods of time is equal to or greater than five seconds.

6. The neurostimulation system of claim 1, wherein at least one of the predetermined periods of time is equal to or greater than one minute.

7. The neurostimulation system of claim 1, wherein at least one of the predetermined periods of time is equal to or greater than five minutes.

8. The neurostimulation system of claim 1, wherein at least one of the predetermined periods of time is equal to or greater than one hour.

9. The neurostimulation system of claim 1, wherein the control circuitry is configured for terminating conveyance of the first electrical stimulation energy only after waiting the selected predetermined period of time.

10. A method of providing therapy to a patient suffering from a symptom of a disease that latently responds to electrical neurostimulation therapy, comprising:

conveying first electrical neurostimulation energy to or from a tissue region of the patient in accordance with a first set of stimulation parameters, thereby affecting the symptom;

waiting a predetermined period of time estimated for the symptom to resolve in response to electrical neurostimulation therapy; and

conveying second electrical neurostimulation energy to or from the tissue region in accordance with a second set of stimulation parameters different from the first set of stimulation parameters.

11. The method of claim 10, further comprising evaluating the effect that the first electrical neurostimulation energy has on the symptom after waiting the predetermined period of time.

12. The method of claim 11, further comprising defining the second set of stimulation parameters based on the evaluation.

13. The method of claim 11, further comprising determining that the symptom did not resolve in response to the first electrical neurostimulation energy after waiting the predetermined period of time, wherein the second electrical neurostimulation energy is conveyed in response to the determination that the symptom did not resolve.

14. The method of claim 10, wherein the disease is a neurological disorder.

15. The method of claim 14, wherein the neurological disorder is Parkinson'"'"'s disease.

16. The method of claim 10, wherein the predetermined period of time is equal to or greater than five seconds.

17. The method of claim 10, wherein the predetermined period of time is equal to or greater than one minute.

18. The method of claim 10, wherein the predetermined period of time is equal to or greater than five minutes.

19. The method of claim 10, wherein the predetermined period of time is equal to or greater than one hour.

20. The method of claim 10, further comprising programming the second set of stimulation parameters into the memory of a neurostimulation device.

21. The method of claim 10, further comprising selecting one of a plurality of predetermined periods of time estimated for a plurality of symptoms to resolve in response to electrical neurostimulation therapy, wherein the selected predetermined period of time is the waited predetermined period of time.

22. The method of claim 10, wherein the conveyance of the first electrical neurostimulation energy is terminated only after waiting the predetermined period of time.
