HR-EEG Contribution in Prognostic Evaluation of Language Development in Children With ASD

The goal of this prospective observational multicentric cohort study is to evaluate the clinical prognostic value of the speech tracking score of language development in children with ASD aged from 3 years to 4 years and half at inclusion. Participants will followed during 4 years with an annual visit. During these visits, each participant will be clinically evaluated (scales and tests) and performed an EEG-HR recording. Two groups will be formed, one with children diagnosed with ASD with language delay, and a control group composed of non-ASD children without language delay, matched on age and gender with the ASD group.
