Auxiliary diagnosis system for disturbance of consciousness based on auditory evoked electroencephalogram signal analysis

Abstract

The invention relates to an auxiliary diagnosis system for disturbance of consciousness based on auditory evoked electroencephalogram signal analysis, and belongs to the technical field of medical diagnosis. The auxiliary diagnosis system comprises an auditory stimulation module, an electroencephalogram signal acquisition module, and an analysis and judgment module; the auditory stimulation module outputs a stimulation audio frequency so as to stimulate the brain of a to-be-tested person; the electroencephalogram signal acquisition module is used for acquiring an electroencephalogram signal generated when the stimulation audio frequency stimulates the brain of the to-be-tested person; and the analysis and judgment module is in communication connection with the auditory stimulation module and the electroencephalogram signal acquisition module, and is used for receiving the electroencephalogram signal and processing the electroencephalogram signal by adopting an LSTM + SVM algorithm and an EEGNet algorithm so as to output a diagnosis result. The diagnosis system provided by the invention only needs a test subject to passively receive the stimulation audio frequency, so that the participation of a professional evaluator is not needed, the professional dependence is low, the diagnosis system is suitable for community popularization, the universality is relatively high, and the diagnosis system has a good application prospect.

Description

technical field [0001] The invention relates to the technical field of medical diagnosis, in particular to an auxiliary diagnosis system for disturbance of consciousness based on the analysis of auditory-induced EEG signals. Background technique [0002] Self-awareness is an individual's awareness of the subjective state of the self. Including awareness of being, awareness of agency, awareness of unity, awareness of unity and awareness of boundaries etc. Impairment of consciousness refers to problems in one or more of the above-mentioned aspects. The patient cannot perceive the existence of the self, cannot realize that he is a single and independent individual, and cannot correctly judge the difference between "I" and "non-self". Common clinical related diseases include senile dementia, schizophrenia, depression, hysteria, depersonalization psychosis, etc. [0003] Most of the existing technologies use the following four methods to solve the problem of disturbance of cons...

Problems solved by technology

[0008] In summary, the above four methods all have the following disadvantages: ① requires the participation of professional evaluators; ② can only be carried out in professional medical institutions; ③ the evaluation scale is slowly iterated with the update of human cognition of the disease, and the specificity is poor; ④ community popularization , it is very difficult to promote; ⑤ requires the active cooperation of the testee; ⑥ high cost, etc.
