Abstract

The invention discloses a children autism risk assessing system based on electroencephalogram, belonging to the field of children autism risk assessment. The children autism risk assessing system based on electroencephalogram comprises a multi-island electroencephalogram signal collecting system, an electroencephalogram signal anti-jamming processing system, an electroencephalogram signal sorting system, an autism risk assessing system and a display system. For the children autism risk assessing system, the multi-island electroencephalogram signal collecting system collects electroencephalogram signals, the jamming signals are primarily processed by a digital filter and an anti-jamming algorithm computer, the errors caused by the jamming signals are effectively avoided by adopting an ARMA model and a self-adaptive predictor based on the ARMA model, then the interference factors are eliminated, meanwhile, the system collects the healthy children data signals and the autism children signals which are labeled, the collected abundant feature information is stored in a first database, the children data signals collected and measured recently are compared with the information, and then the reasonable autism risk result is given.

Description

technical field [0001] The invention relates to the field of risk assessment of children's autism, and more specifically, relates to a system for assessing the risk of children's autism based on brain electricity. Background technique [0002] Autism is classified as a developmental disorder caused by nervous system disorders, unable to perform normal language expression and social activities, and often does some stereotyped and repetitive actions and behaviors. EEG is mainly used clinically to check Brain function, diagnosis of nervous system disorders, EEG has no side effects, and structural damage can be found. It not only provides the location and degree of abnormal function, but also obtains key information about abnormal brain function. Can play a certain role in closed disease. [0003] When EEG monitoring is performed on children, EEG technology is mostly used in relatively strict environments, such as clinical treatment in hospitals or laboratories in scientific re...
