Systems and methods for treating pain using brain stimulation
The invention comprises systems and methods for treating nociceptive pain including at least one force-regulatable device in mechanical, electrical, or chemical communication with at least one brain area identified as processing nociceptive pain signals. The force-regulatable device acts to alter the nociceptive pain signals in a brain area to alleviate nociceptive pain.
1. A method for treating nociceptive pain, comprising:
contacting at least one region of the insula using a force-regulatable device;
applying a mechanical stimulus to the at least one region of the insula to alter nociceptive pain signals; and
alleviating nociceptive pain by altering the nociceptive pain signals in the at least one region of the insula.
2. The method of claim 1 , further comprising identifying the insula prior to contacting the at least one region of the insula using a force-regulatable device.
3. The method of claim 1 , wherein contacting the at least one region of the insula comprises surgically implanting the force-regulatable device.
4. The method of claim 1 , further comprising providing an electrical stimulus.
5. The method of claim 1 , further comprising providing a chemical stimulus comprising ionic solutions comprising potassium ions (K+) or sodium ions (Na+), neurotransmitters comprising norepinephrine, glycine, aspartic acid, aspartate, glutamic acid, glutamate, gamma-amino butyric acid (GABA), acetylcholine, dopamine, or serotonin, medications that increase the level of a neurotransmitter, such as flouxetine and trazodone, chemicals or compounds that act to inhibit axonal or neuronal activity, local anesthetics, such as lidocaine and marcaine, or drugs that act to block or relieve pain, such as morphine or its derivatives, and opioid peptides, such as endorphins, enkephalins, and dynorphins.
6. The method of claim 1 , wherein the at least one region of the insula is in the left hemisphere of the brain or in the right hemisphere of the brain.
7. A method for treating chronic nociceptive pain, comprising:
implanting at least one force-regulatable device in mechanical communication with the cingulated gyms or with at least one region of the insula; and
applying mechanical stimulation to the cingulated gyms or to the at least one region of the insula to alter nociceptive pain signals; wherein the force-regulatable device is in communication with a mechanical power source.
8. The method of claim 7 , comprising identifying the cingulated gyms or the at least one region of the insula prior to implanting the at least one force-regulatable device.
9. The method of claim 7 , wherein implanting the at least one force-regulatable device comprises securing the force-regulatable device about the dura such that the force-regulatable device exerts a mechanical force on the cingulated gyms or the at least one region of the insula.
10. The method of claim 7 , further comprising applying electrical stimulation to the cingulated gyms or the at least one region of the insula, wherein the stimulation comprises applying electrical stimulation from about 1 V to about 25 V and from about 10 Hz to about 200 Hz frequency.
11. The method of claim 7 , further comprising providing chemical stimulation by applying a neurotransmitter or a pain reliever to the cingulated gyms or the at least one region of the insula.
12. The method of claim 7 , wherein the at least one region of the insula is in the left hemisphere of the brain or in the right hemisphere of the brain.
13. A method for treating nociceptive pain, comprising:
contacting the cingulated gyms using a force-regulatable device;
applying a mechanical stimulus to the cingulated gyms to alter nociceptive pain signals; and
alleviating nociceptive pain by altering the nociceptive pain signals in the cingulated gyrus.
14. The method of claim 13 , further comprising identifying the cingulated gyms prior to contacting the cingulated gyms using a force-regulatable device.
15. The method of claim 13 , wherein contacting the cingulated gyms comprises surgically implanting the force-regulatable device.
16. The method of claim 13 , further comprising providing an electrical stimulus.
17. The method of claim 13 , further comprising providing a chemical stimulus comprising ionic solutions comprising potassium ions (K+) or sodium ions (Na+), neurotransmitters comprising norepinephrine, glycine, aspartic acid, aspartate, glutamic acid, glutamate, gamma-amino butyric acid (GABA), acetylcholine, dopamine, or serotonin, medications that increase the level of a neurotransmitter, such as flouxetine and trazodone, chemicals or compounds that act to inhibit axonal or neuronal activity, local anesthetics, such as lidocaine and marcaine, or drugs that act to block or relieve pain, such as morphine or its derivatives, and opioid peptides, such as endorphins, enkephalins, and dynorphins.
