BACKGROUND: Autism Spectrum Disorder (ASD) is a complex neurodevelopmental trouble which prevents the child from socio-communicative interaction, and learning from his environment. Non-medical early intervention attempts to improve prognosis. We will review the main current hypothesis, intervention models and scientific supports about early intervention. METHODS: We conducted a search of the literature published on Medline between 2010 and 2015 related to intervention models provided to children with ASD aged less than 3 years. Data were extracted from systematic reviews and recent randomized controlled trials with moderate to high GRADE quality of evidence. RESULTS: Early intervention refers to brain plasticity theory. With the epidemiological studies of infant "at risk" there is an attempt to intervene earlier before full syndrome is present. Interventions tend to follow more on a developmental hierarchy of socio-communicative skills and to focus on the dyadic relation between the child and the caregivers to improve the core autistic symptoms. Over the last 6 years, there's been news and fine-tuned ways about early intervention, and more and more systematic evaluation. CONCLUSION: However, there are only few interventions which were evaluated in trial with a strong GRADE recommendation and all of them have methodological concerns. It is important to be cautious in recommendations for mental health politic, even if it is important to improve access to services for all children and their families, hence finance and design rigorous project in research.
