Screening for Neurodevelopmental Disorders in Siblings of Children With Autism Diagnosed in Tertiary Centers

Screening for Neurodevelopmental Disorders in Siblings of Children With Autism Diagnosed in Tertiary Centers

In this study, a selective and multi-stages screening for neurodevelopmental disorders (NDD) in siblings of children with a confirmed ASD is done. The main aims are to estimate the prevalence of NDD among siblings and to evaluate the feasibility and acceptability of a standardized screening procedure.

Although NDD are frequent among siblings of children with ASD, their developmental screening is not yet sufficiently organized in routine practice. The needs and the characteristics of these siblings have yet to be better understood in order to define their developmental surveillance.
