Detailed Description

The diagnosis of developmental disorders in adults is still difficult. Indeed, in France, there is not questionnaires to easily and accurately diagnose this disorder. Several diagnostic scales were developed in English. Among them, RAADS-R scale, which is a clinical tool that aims to better identify autism spectrum disorders including mild forms in adult people and help to diagnose of high-functioning autism .
