Abstract

The invention relates to a children's ASD diagnosis device based on magnetoencephalogram and electroencephalogram, comprising a magnetic shielding system, a head-mounted electroencephalogram and magnetoencephalogram array sensor system, an electroencephalogram and magnetoencephalogram data acquisition system, Sensory stimulation system, signal processing and data analysis system; magnetic shielding system can effectively reduce background magnetic field noise, head-mounted electroencephalogram and magnetoencephalogram array sensor system can collect the whole brain of the tested children through combination and nesting, The EEG and MEG data acquisition system can record the electrical activity information of the brain, the sensory stimulation system can present visual and auditory sensory stimuli for the children under test, and the signal processing system can remove biological magnetic noise and background magnetic noise; the data analysis system The pathological features in the signal can be extracted for analysis. The invention has the advantages of high sensitivity and specificity, multiple sources of information, high signal quality, easy acceptance by children and the like. The invention has the advantages of high sensitivity and specificity in the diagnosis of ASD in 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...
