Active clinical trials for "Child Development Disorders, Pervasive"

This study seeks to correlate microbiome sequencing data with information provided by patients and their medical records regarding autism.

The aim of the protocol is to better understand the impairments in visual processing, as such impairments may induce social interaction difficulties in subjects with autism spectrum disorders (adults and children) and schizophrenia, like face exploration.The same protocol will be used for the three populations, each population being compared with matched controls. The explorations are designed to test two different hypotheses regarding the mechanisms of the visual perception difficulties of the two populations. Even though difficulties to extract the global form of objects have been described in both subjects with autism and schizophrenia, we will test two different hypotheses for the two populations. We will test the hypothesis that subjects with autism display an advantage for the processing of local information arising at an early level of processing, whereas disorders observed in patients with schizophrenia originate from attention disorders. The protocol includes three consecutive studies, each one being applied in each of the three populations.

The main objective of the study is to define, for Autism Spectrum Disorder, the extent of genetic variation in synaptic pathways that may be targeted for therapeutic development. For this purpose the investigators will take advantage of large, well-characterized cohorts of patients with Autism Spectrum Disorder for genetic screenings. Targeted sequencing of selected synaptic genes, previously associated with Autism Spectrum Disorder, will be carried out in these cohorts with deep coverage of coding regions and a strong focus on previously untested regulatory regions. Genomic data from Copy Number Variant, whole genome sequencing and exome sequencing, available for some of these patients, will be integrated in the overall analysis. The investigators will strongly emphasize the establishment of comprehensive genotype/phenotype correlations and set up an induced Pluripotent Stem Cells collection from selected patients with synaptic mutations for functional and expression analysis.

With this investigation, researchers wil look for a link between the appearance of anorexia nervosa and autism spectrum disorders in minors. Previous studies made clear already that patients with anorexia nervosa show elevated characteristics of autism spectrum disorder, when being meassured in adults and in patients in the acute fase of their anorexia nervosa. The purpose of this invenstigation is to see if their is also an elevated incidence of characteristics of autism spectrum disorder in minors with anorexia nervosa in remission.

Autism Spectrum Disorder (ASD) is lifelong neurodevelopmental disorder that affect social communication and interaction and includes limited and repetitive patterns of behavior (DSM 5). In France, national guidelines about practices recommends early and specific interventions but care pathway are not well described for ASD children. The national health insurance information system record demographic data, medical condition, and reimbursed drug over 98% of the French population. In addition, the ELENA cohort is a large cohort of children with ASD followed for 6 years. Data collected include clinical characteristics of children (IQ, severity of ASD...) and parents (educational level, professional status...). The first objective of this project is to identify patterns of care trajectories using data from ELENA cohort matched to data from national health insurance information system. Secondary objectives are to examine the links between patterns of care trajectories and clinical characteristics, social environment of autistic children.

Co morbidity rates of hearing loss in children with autism spectrum disorder are high and increasing. Investigators are aiming to: evaluate peripheral auditory and brain stem auditory function in children with autism spectrum disorder. compare communication capabilities in autistic children having hearing abnormalities and autistic children with normal hearing.

The aim of the study is to describe the feasibility of the passation of the assessment battery of psychomotor functions tests (NP-MOT) in children aged 4 to 11 years with a diagnosis of autism spectrum disorder: number and type of evaluable events, number and type of tests with a deficit compared to the standard results.
