There are two groups of RBs: lower-order (e.g. motor stereotypies) and higher-order RBs (e.g. restricted interests), linked to sensory-motor and the associative loops, respectively. To date, treatment options for RBs are very limited. High-definition transcranial direct current stimulation (HD-tDCS) may be effective in reducing the impact of RBs in children with ASD by targeting the associated brain alterations. Moreover, the high focality of HD-tDCS will help the investigators to disentangle the relative contribution of different brain loops (namely, sensory-motor and the associative loops) into RBs subtypes. The investigators will also study the electrophysiological patterns associated to behavioral changes after the application of HD-tDCS.",[83],"Autism Spectrum Disorder",[83,85,86,87,88,89],"HD-tDCS","Restricted Interests","Repetitive Behaviors","Neurodevelopmental Disorders","transcranial direct current stimulation","2024-10-15",{"date":92,"type":93},"2024-10-17","ACTUAL",{"date":95,"type":93},"2024-10-03",{"date":97,"type":77},"2026-04",{"name":5,"class":6},1]
