Embodiment Construction

[0015] see figure 1 and 2 ,this invention figure 1 The preferred embodiment shown incorporates a data acquisition unit (DAU) 20 which is used to acquire EEG signals from the patient 10 at step 22 for further processing. DAU 20 generally consists of a computer system with an integrated analog-to-digital (A-D) converter 25 and a set of electrodes representatively shown placed over the patient's 10 scalp. Although only a single electrode 15 is shown, any combination of multiple electrodes may be used in the present invention to obtain EEG signals. A-D converter 25 is used to convert at step 24 the analog EEG signal obtained from electrodes 15 into a sample set of signal values, which are then analyzed by processor 35 of data computing unit (DCU) 30 . The DCU 30 incorporates a processor 35 and a communication device that receives samples from the DAU 20 . In this preferred embodiment, the processors of DAU 20 and DCU 30 are the same processor. However, in an alternate embodim...

Abstract

The present invention relates to a system and method of predicting adverse events in psychological and neurological treatment, particularly a system and method that export and calculate characteristics and index of adverse events possibilities in psychological and neurological like suicidal thoughts and / or actions. The system and method also predict possibilities of suicidal thoughts and / or actions before or during the process of psychological treatment. In order to acquire such characteristics and index, a power spectrum and a time-domain value are exported according to biopotential signals acquired from tested patients. The system and method also can recognize people in danger (for example, suicide) that might go through symptom variation (especially depravation) like psychological and neurological adverse events of suicidal thoughts or actions.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application Serial No. 60 / 643,350, filed January 12,2005. Background technique [0003] Depression is a mood disorder that affects 17 million Americans and accounts for 9.7 million visits each year. It affects patients in a variety of ways, leading to depressed mood, irritability, sleep disturbances, feelings of restlessness, guilt and worthlessness, lack of energy and motivation, inability to concentrate, and increased rates of suicide. There are many antidepressants available and their efficacy is quite high once an appropriate treatment regimen has been established. [0004] Major depressive disorder (MDD) is the psychiatric diagnosis most commonly associated with attempted suicides. The American Association of Suicidology states on their web page that the lifetime risk of suicide in untreated MDD patients is approximately 20%. About 2 / 3 of people who have committe...
