  • Publication number: 20060167370
    Abstract: The present invention is a system and method of deriving and computing features and indices that predict the likelihood of psychological and neurological adverse events such as suicidal thoughts and/or actions. The method of the present invention further predicts the likelihood of suicidal thoughts and/or actions prior to and or during treatment for psychological disease. To obtain such features and indices, power spectrum and time domain values are derived from biopotential signals acquired from the subject being tested. The system and method identify people who are likely to experience changing, especially worsening, symptoms of psychological and neurological adverse events such as suicidal thoughts or actions and who therefore may be at risk (e.g. suicide).

  • Publication number: 20060149160
    Abstract: The invention provides a method of estimating cerebral sources of electrical activity from a small subset of EEG channels utilizing existing methods to provide a 3-dimensional, discrete, distributed, linear solution to the inverse problem using inputs consisting of a small number of EEG channels (e.g., 4 channels) augmented with synthetic EEG data for the other channels. The resultant image of cerebral electrical activity in the region of the EEG channels from which data is recorded is of comparable spatial resolution in the corresponding region to images of cerebral electrical activity obtained using a complete set of EEG channels (e.g., using 24 channels).

  • Publication number: 20050216071
    Abstract: Disclosed is a system and method of assessing the efficacy of and predicting response to 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. Pretreatment indices represent a patient's neurological or psychological state and therefore may be used to predict the response to treatment. Changes in these parameters may be used to assess the efficacy of treatment and to modify the treatment to optimize the resultant patient state.
