Embodiment Construction

[0025] The invention described herein is a method for assessing therapeutic effects against neurological and psychological disorders by assessing changes in neural activity manifested in EEG. A particular embodiment of the present invention involves a system for evaluating neurostimulators 60 connected to a patient 10 via stimulating electrodes ( figure 1 ) provides the electrical stimulation effect. The system includes a data acquisition unit (DAU) 20 for acquiring patient EEG signals for subsequent processing. DAU 20 typically includes a computer system with an analog-to-digital (A-D) converter 25 and a series of electrodes 15 that can be placed on the patient's 10 scalp. An A-D converter is used to convert the analog EEG signal obtained from a series of surface electrodes into a sample set of signal values ​​that can be analyzed by the computer of the data computing unit (DCU) 30 . The DCU 30 includes a processor 35 and a communication device 36 for receiving sampled valu...

Abstract

Disclosed is a system and method of assessing the efficacy of treatment of neurological or psychological disorders. The preferred embodiment uses at least two surface electrodes to acquire EEG signals from the surface of a patient's body, a processor for computing from the EEG signals various features and indices that are representative of the patient's neurological or psychological state. Changes in these parameters may be used to assess the efficacy of treatment and to modify the treatment to optimize the resultant patient state.

Description

[0001] related application [0002] This patent application claims priority to US Provisional Patent Application 60 / 468,350, filed May 6, 2003, and US Provisional Patent Application 60 / 534,247, filed January 5, 2004. Background technique [0003] Various treatments are available for various neurological and psychological disorders. For many disorders, the use of pharmaceutical agents is the most common method of treatment. For disorders with symptoms that are resistant to pharmacologic therapy or not available, other therapies, including neurostimulation, may be used. [0004] Neurostimulation is a disease treatment method that uses an electrical stimulator to generate an electrical signal to stimulate the central nervous system (CNS), usually directly or by stimulating the peripheral nervous system (active). Such neurostimulators and their corresponding electrodes are usually implanted in the patient's body. There are two main neurostimulation therapies for central nervous...
