Abstract
Abstract A method and system for treating a patient having a pathological condition characterized by asymmetry between brain waves measured from two locations of the scalp. The method comprises the steps of attaching a first electrode to a first scalp location of the patient and a second electrode to a second scalp location of the patient. Then, brain waves of the patient are recorded from the electrodes. These brain waves are used for the purpose of biofeedback. Specifically, the brain wave asymmetry is presented to the patient and the patient is rewarded for changing the asymmetry.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
101 words
A method for modifying a condition of a patient, said condition being characterized by asymmetry between brain waves measured from at least two different locations of the patient's scalp, comprising the steps of: testing the patient for the condition characterized by asymmetry between brain waves from at least two scalp locations; attaching a first electrode to a first scalp location of the patient; attaching a second electrode to a second scalp location of the patient; recording brain waves of the patient from the electrodes; and rewarding the patient for changing asymmetry between the brain waves recorded from the two scalp locations.
Claim 2
Independent Claim
101 words
A method for modifying a condition of a patient, said condition being characterized by asymmetry between brain waves measured from at least two different locations of the patient's scalp, comprising the steps of: testing the patient for the condition characterized by asymmetry between brain waves from at least two scalp locations; attaching a first electrode to a first scalp location of the patient; attaching a second electrode to a second scalp location of the patient; recording brain waves of the patient from the electrodes; and rewarding the patient for changing asymmetry between the brain waves recorded from the two scalp locations.
