[Early detection of autism spectrum disorders].

The evaluation of the development of young children had to consider the possible detection of neurodevelopmental disorders in particular autism spectrum disorders. When a child of 18 months has a developmental language delay or a defect in social contact, the hypothesis of autism must be considered through a clinical evaluation. We will point out some clinical guidelines and some early signs to detect the trouble and to propose early treatment interventions. This will help to develop specific skills of the child aiming at influencing positively clinical evolution and reducing mental retardation.
