简要总结
In this proposed study, a transcranial direct current stimulator is used to intervene in the medial prefrontal cortex of children with autism, and the efficacy of this intervention method is evaluated, as well as the internal mechanism of Autism Spectrum Disorders' intervention is discussed.
详细描述
This is a randomized controlled double-blind trial. Using a transcranial direct current stimulator to stimulate the Autism Spectrum Disorders of children with autism, place an anode patch on Fz and a cathode patch on right cheek to observe whether it can improve social and cognitive function in autism. Parameter settings: The current size is 1.5mA. Treat twice a day for 20 minutes, for a total of 7 days.

结局指标
主要结局
Autism assessment assessment index
时间窗: Baseline, the day after intervention, three weeks after intervention
3\. Autism was assessed using the Oregon State University Autism Rating Scale, DSM-5 (OARS-5), which includes the signs and symptoms of autism spectrum disorders described in the DSM-5. The scores include :1; Total number of symptoms. Every symptom that occurs (i.e., 1, 2, or 3 points) is recorded in the symptom count. 2. Weighted average severity. The clinician scored each item on a scale of 0, 1, 2 or 3 based on the parent's description of the particular problem. 3. Damage index. In Section C of OARS-5, after discussion with the child/adolescent's caregiver, the clinician will rate the level of support on a scale of 0(no support) to 3(maximum support).
