Systems and methods for selecting stimulation sites and applying treatment, including treatment of symptoms of parkinson's disease, other movement disorders, and/or drug side effects
View Patent ↗Methods and systems for treating movement disorders are disclosed. A method in accordance with one embodiment can include determining that the movement disorder affects the patient's gait, oral functioning, and/or other functioning, and applying electrical stimulation proximate to the interhemispheric fissure, the Sylvian fissure, or between the two fissures, respectively. In another embodiment, the method can include selecting at least one neural process from among a plurality of processes sequentially carried out by a patient to cause a muscle movement in the patient (e.g., a planning process, an initiation process, and an execution process), and applying electrical stimulation to a location of the patient's brain associated with the at least one neural process.
1. A method for reducing drug side effects on a patient, comprising:
determining an aspect of the patient's functioning that is negatively affected by a drug in which the patient consumes as part of a therapy to treat a movement disorder or to treat symptoms associated with a movement disorder;
positioning at least one electrode device having a plurality of electrical contacts such that at least one electrical contact is positioned below the patient's skull on the dura over a target cortical location selected from the group consisting of prefrontal cortex, supplemental motor cortex and motor cortex; and
applying electrical stimulation to the cortical region of the patient's brain that is associated with the functioning such that the electrical stimulation reduces the drug side effects.
2. The method of claim 1 wherein determining an aspect of a patient's functioning includes determining an aspect of the patient's motor functioning that is influenced by the patient's consumption of drugs that are administered to reduce symptoms of Parkinson's disease.
3. The method of claim 1 wherein determining an aspect of a patient's functioning includes determining an aspect of the patient's cognitive functioning that is influenced by the patient's consumption of drugs that are administered for controlling symptoms of Parkinson's disease.
4. The method of claim 1 wherein determining an aspect of a patient's functioning includes determining an aspect of the patient's motor functioning that is influenced by the patient's consumption of drugs that are administered to reduce symptoms of a movement disorder.
5. The method of claim 1 wherein determining an aspect of a patient's functioning includes determining an aspect of the patient's cognitive functioning that is influenced by the patient's consumption of drugs that are administered to reduce symptoms of a movement disorder.
6. The method of claim 1 wherein the drug side effects comprises effects on the patient's cognitive and/or motor functioning.
7. The method of claim 6 wherein the effect on the patient's motor functioning comprises unwanted dyskinesias.
8. The method of claim 1 wherein the movement disorder is Parkinson's disease.
9. The method of claim 1 wherein the drug comprises a dopamine precursor or dopamine related compound.
10. A method for reducing the side effects of drug therapy in a Parkinson's patient comprising:
identifying a patient in which the patient is receiving a drug therapy to reduce symptoms associated with Parkinson's disease;
determining a motor function and/or cognitive complication associated with the patient's consumption of the drug therapy and based upon the complication positioning an electrode device having a plurality of electrical contacts such that at least one electrical contact is positioned below the patient's skull and on the dura over a target cortical location of the patient's brain associated with the complication selected from the group of cortical locations consisting of prefrontal cortex, supplemental motor cortex, and motor cortex;
applying electrical signals to the plurality of electrical contacts to stimulate the target location of the patient's brain associated with the complication and thereby reducing the complication associated with the drug therapy.
