Intervention Effect of Computer Cognitive Training for Children with ADHD Based on fNIRS：A Pilot Study

Objective：To investigate the activation of brain regions and the changes of clinical symptoms and cognitive function in children with ADHD after computerized cognitive training intervention based on near-infrared functional brain imaging (fNIRS) Method :18 ADHD children received computer cognitive function training were collected from October 2020 to June 2021, 1. To compare the changes of behavioral data, cerebral cortex activation, SNAP-IV assessment ,PSQ assessment and cognitive function when the ADHD children performed the go/nogo and nback tasks before and after the intervention. Results:The accuracy rates were significantly improved when children performed the go/nogo task and the nback task.After the intervention,the fNIRS data shows the right middle frontal gyrus and dorsolateral prefrontal cortex were significantly activated . Comparing the fNIRS data before and after the intervention with the data of normal children, there was a difference in the activation of the left middle frontal gyrus, and the ß value of nogo-go after the intervention was closer to normal.Clinical symptoms, behavioral problems, and cognitive function of ADHD children are improved after intervention. Conclusion：Computer cognitive training can improve the activation level of brain regions in ADHD children and the activation level tends to be normal compared with no intervention;The clinical symptoms, behavioral problems and some cognitive functions of ADHD children were significantly improved after the intervention. It is suggested that non-drug therapy can improve the core clinical symptoms, behavioral problems and cognitive function while improving the inhibitory control function and the activation level of brain regions in ADHD children.
