Schizophrenia screening method based on portable EEG equipment

Abstract

The invention discloses a schizophrenia screening method based on portable EEG equipment. The method comprises an electroencephalogram signal collection and discrimination step. The electroencephalogram signal collection and discrimination step comprises the following steps: 1, carrying out signal induction through 1-4 lead high-sensitivity electrode slices, carrying out collection of original electroencephalogram signals, and carrying out signal stability test on the original signals through an impedance test module. According to the invention, the original electroencephalogram signals are collected in a portable manner through electroencephalogram, synchronization signal amplification is carried out, the electroencephalogram signals are transmitted through wireless transmission, electroencephalogram signals are received at the mobile terminal, and the received signals communicate with the cloud for storage. Through an electroencephalogram preprocessing algorithm, an electroencephalogram signal identification algorithm and a corresponding electroencephalogram machine learning algorithm and a deep learning algorithm, brain function and the schizophrenia disorder are measured and evaluated by analyzing and calculating acquired data of brain signals of people under different types and states and comparing electroencephalogram signals of confirmed schizophrenia patients.

Description

technical field [0001] The invention belongs to the technical field of EEG electroencephalogram signal recognition and mental disease screening, and in particular relates to a screening method for schizophrenia based on a portable EEG device. Background technique [0002] Brain cognition is the process in which the human brain receives external information, processes it, and converts it into internal mental activities, thereby acquiring knowledge or applying knowledge. Cognitive impairment refers to the impairment of one or more of the above several cognitive functions and affects the daily or social ability of the individual. [0003] Schizophrenia is a group of common mental diseases with unknown etiology. It usually occurs in young and middle-aged people. There are often obstacles in perception, thinking, emotion, and behavior, as well as incoordination of mental activities. The course of the disease is protracted and can often develop into mental decline. and other feat...

Problems solved by technology

[0007] The problem is that, for most groups, the filling of the questionnaire is relatively random, and the information is often distorted, resulting in large errors in the judgment of the results

The interviews with psychiatrists are also inconsistent due to their different levels, so the conclusions obtained cannot be unified.
