Children ASD diagnosis device based on magnetoencephalogram and electroencephalogram

Abstract

The invention relates to a children ASD diagnosis device based on a magnetoencephalogram and an electroencephalogram. The children ASD diagnosis device comprises a magnetic shielding system, a head-mounted electroencephalogram and magnetoencephalogram array type sensor system, an electroencephalogram and magnetoencephalogram data acquisition system, a sensory stimulation system, a signal processing system and a data analysis system. The magnetic shielding system can effectively reduce background magnetic field noise. The head-mounted electroencephalogram and magnetoencephalogram array type sensor system can carry out whole-brain collection on a tested child in a combined nesting mode. The electroencephalogram and magnetoencephalogram data acquisition system can record brain electrical activity information. The sensory stimulation system can present visual and auditory sensory stimulation for the tested child. The signal processing system removes biological magnetic noise and backgroundmagnetic noise. The data analysis system can extract pathological features in the signals for analysis. The children ASD diagnosis device provided by the invention has the advantages of high sensitivity and specificity, multiple information sources, high signal quality, easy acceptance by children and the like. The children ASD diagnosis device has the advantages of high sensitivity and specificity in the aspect of ASD diagnosis of children.

Description

technical field [0001] The invention belongs to the field of medical diagnosis systems, and relates to a children's ASD diagnosis device based on magnetoencephalography (Magnetoencephalography, MEG) and electroencephalography (Electroencephalography, EEG). Background technique [0002] Autism spectrum disorder (ASD) is a neurodevelopmental disorder affecting approximately one in 45 school-age children. Characterized by inadequate social communication and repetitive or monotonous behavioral patterns, these symptoms usually appear in the first few years of life and persist throughout life, even if remission in adulthood, early atypical developmental disturbance It still has a greater impact on patients in adulthood. [0003] Although considerable research has been done to identify abnormal brain development in ASD, there is still no consistent result as to how this leads to the clinical and behavioral manifestations. Brain structural studies have found only subtle group diff...

Problems solved by technology

[0008] Therefore, the existing ASD children lack the diagnostic indicators of quantitative electrophysiological analysis, the diagnostic methods are not objective, and the current experimental requirements are not humanized enough.
