ABSTRACT

From pervasive developmental disorder in ICD-10 to Autism Spectrum Disorder in ICD-11 Abstract. This article presents the new diagnostic classification of Autism Spectrum Disorder according to ICD-11 relative to the previous classification according to ICD-10, and DSM-5. It also provides some practical clinical advice regarding the value of multiaxial diagnostic classification. Because ICD-11 shows a high similarity to DSM-5, one may expect prevalence rates to be consolidated. Especially because the classification "atypical autism" has been dropped, prevalence rates may decrease following the implementation of ICD-11 compared to ICD-10. Sensitivity should remain high, however, and specificity may increase, similar to the changes that occurred going from DSM-IV TR to DSM-5.
