[On the benefits to keep using the asperger diagnosis]

The purpose of this paper is to examine the possible benefits to keep using the diagnosis of Asperger's syndrome. We first describe the evolution of this entity over time and within nomenclature bases such as the ICD- 10, the CFTMEA and the last versions of DSM. Then, we discuss more precisely the impact of the decision made in the DSM-5 to suppress the Asperger syndrome as a differentiated entity within the pervasive developmental disorders (PDD). This disorder chapter by the way also disappears and is replaced by Autism Spectrum Disorder (ASD). We present here three clinical cases encountered in an outpatient general child psychiatry clinic : 1 case was diagnosed as Asperger syndrome, 1 as infantile autism (early infantile autism) and 1 as another pervasive developmental disorder (psychotic disharmony). The objective was to expose the commonali ties and differences between these three entities. We conclude that keeping using the Asperger diagnosis is important for the clinical management of these clinical situations but also for the individual, his or her family and society at large.
