Using a New Calibrated Tool in Specific Language and Learning Disorders : the BMTi

Study Overview
=================
Brief Summary
-----------------
The group of experts at HAS has defined the places of first and second-line workers in specific disorders of development and learning, as defined in the international diagnostic classifications International Classification of Diseases (CIM) CIM 11 and Diagnostic and Statistical Manual of Mental Disorders (DSM) DSM 5. The referral to a second-level structure, a multidisciplinary structure in charge of carrying out the different cognitive assessments, requires a preliminary evaluation. This orientation is based on a medical consultation, carried out by a doctor specialized in the field, with an exploration tool adapted to the different fields concerned. The BMTi, a battery of third-generation tests (after the Rapid battery of evaluation of the cognitive functions (BREV) and then the Evaluation of cognitive functions and learning of the child (EDA)) will enable the doctor, from 2018, to carry out this orientation in a relevant way in response to children with a complaint about neurodevelopment and learning. . The research project aims to validate this hypothesis, by comparing the diagnoses posed in a conventional way with the various multidisciplinary assessments, with the results of the transfer of all or part of the subtests of the BMTi by a doctor of second resort.

This research project finds its place in a more global approach for a complete application of the recommendations of the group of experts of the High Authority of Health with: the systematic evaluation of educational prevention strategies by intensive training in small groups of children with similar needs, in schools, the evaluation of the role of the primary care physician in the prescription of the initial investigation report in the face of a simple reading, writing or numeracy disorder (research project with letter of intent filed in the framework of the call for tenders 38/5000 general direction of the offer of care (DGOS) PREPS 2018), the current project to validate referral tools to second-level appraisals, an evaluation project of the financing modalities filed under the regional health agency Occitanie in the framework of the call for tenders of article 51, the introduction of training courses for the first and second-line tools for ambulatory doctors.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
