Impact of Early Interventions on Neurocognitive Profile of Children With Autism Spectrum Disorder — IDEAEYE  

Autism Spectrum Disorder Clinical Trial

Official title: Impact of Early Intervention on Neurocognitive Profile of Children With Autism Spectrum Disorder

Status Terminated

Clinical Trial Summary

The Early start Denver model (Rogers, 2010; Dawson, 2010) is a developmental and behavioral model that aim to enhance socio-comunicative abilities and also global development of children with Autism spectrum disorder (ASD). The purpose of this study is to identify changes in neurocognitive profile of children population with ASD receiving Early Start Denver Model (ESDM) applied 12 hours per week in comparison to children receiving other interventions. That is a study proposed to children with ASD and their families that participate already to a randomized control study called IDEA registered on clinicaltrials.gov NCT02608333.

the investigators hypothesized that ESDM would increase social cognition, reduce shifting attention time and increase preference for unpredictable stimuli.

Clinical Trial Description

IDEA is a multicenter (4 centers in France and 1 center in Belgium), randomized, controlled, single blind trial using a modified Zelen design .It concerns children with ASD aged 15 to 36 months without severe neurological or physical disorder and living in the proximity of one the early intervention units. After diagnostic, Children will be included in a longitudinal cohort with the consent of the parents. Sixty children will be drawn lots among 180 children of the cohort and will be included in an ESDM intervention with the consent of the parents. Two groups will be compared: an experimental group of 60 children receiving 12 hours a week of ESDM intervention delivered by trained therapists during 2 years and a control group of 120 children receiving typical heterogeneous 'as-usual' intervention proposed by professionals and public services over the same period. In IDEA development of communication and social interactions and global developmental of all the children will be measured at different time points (at baseline (t0), after 1 year (t1), after 2 years( t2)) over the two years through standardized tests such as Autism diagnostic observation Schedule (ADOS-2), Mullen Scales of Early Learning (MSEL) and the Vineland Adaptive Behavior Scale (VABS-2).

Children will be included in this second study called IDEA-EYE with parents' consent. Then, preference for biological motion and social scene, shifting attention time and preference for sameness will be measure in both groups with an Eye-tracker Tobii TX 300 at t0,t1 and t2. These measures will also be collected in a group of children without ASD at t0,t1 and t2.

the investigators expect, as primary criteria, a significant superior time spend on biological motion in ESDM group versus control group after 2 years of treatment. the investigators also expect a significant superior orientation toward eyes in complex social scenes, an inferior shifting attention time and a superior preference for unpredictable stimuli in ESDM group versus ASD control group after 2 years. the investigators also expect that ESDM group would have time spend on biological motion, orientation toward eyes in complex scenes, shifting attention time and preference for unpredictable stimuli comparable to children without ASD after 2 years.

This study would allow better understanding of ESDM active principles. ;
