[Diagnosis of pervasive developmental disorders without mental retardation and its impact on obtaining social and educational services in Quebec].

Pervasive developmental disorders without mental retardation is a new clinical category including high-functioning autism, Asperger syndrome and pervasive developmental disorder non otherwise specified. Its recognition is recent and still problematic in many regards. This article reviews the historical, theoretical and clinical relations between pervasive developmental disorders without mental retardation and bordering disorders. The consequences of an inadequate diagnosis on measures of assistance for these patients is also investigated. The authors conclude on the necessity in considering, independently of the diagnosis, the description of symptoms, the intellectual level and the adaptative level in order to take the most appropriate educational and psychosocial decisions regarding pervasive developmental disorders without mental retardation.
