Methods for treating essential tremor

A method for treating essential tremor, comprising:

• identifying a muscle action subject to essential tremor;
• monitoring a first image of the patient's brain function while the patient is not performing the muscle action;
• monitoring a second image of the patient's brain function while the patient performs the muscle action;
• comparing the first and second images to identify a stimulation site of the brain;
• placing at least one electrode at least proximate to the stimulation site;
• at least reducing the patient's essential tremor motion by applying an electrical stimulation at least proximate to the stimulation site.

A method for treating essential tremor, comprising:

• directing a patient to perform a muscle action;
• while the patient performs the muscle action, directing a collection of information corresponding to a level of neural activity in the patient's brain;
• directing a comparison of a first portion of the information corresponding to a level of neural activity at the left hemisphere of the patient's brain with a second portion of the information corresponding to a level of neural activity at the right hemisphere of the patient's brain;
• and
• at least reducing an essential tremor motion of the patient by applying an electrical stimulation at least proximate to a stimulation site, with a location of the stimulation site being based at least in part on the comparison of the first and second portions of the information.

A method for treating essential tremor, comprising:

• directing a patient to perform an action with a first muscle on a first side of the patient's body, the first muscle being controlled by a second hemisphere of the patient's brain;
• while the patient performs the action with the first muscle, directing a collection of first information corresponding to a level of neural activity in the patient's brain;
• directing the patient to perform an action with a second muscle on a second side of the patient's body, the second muscle mirroring the first muscle and being controlled by a first hemisphere of the patient's brain;
• while the patient perform an action with the second muscle, directing a collection of second information corresponding to a level of neural activity in the patient's brain;
• and
• at least reducing an essential tremor motion of the patient by applying an electrical stimulation at least proximate to a stimulation site, with a location of the stimulation site being based at least in part on a comparison of the first information with the second information.

A method for treating essential tremor, comprising:

• directing a collection of first information corresponding to a level of neural activity in the patient's brain while the patient performs a muscle action;
• affecting the patient's motor nerves by introducing a drug into the patient's body;
• directing a collection of second information corresponding to a level of neural activity in the patient's brain while the patient performs the muscle action and while the patient is under the influence of the drug;
• and
• at least reducing the patient's essential tremor motion by applying an electrical stimulation at least proximate to a stimulation site, with a location of the stimulation site being based at least in part on the comparison of the first information with the second information.
