There are rumours circulating that ICD-11 will more closely align itself with the American DSM-5 and exclude the term Asperger Syndrome by incorporating into Autism Spectrum Disorder. I have had a look at the draft of ICD-11 and found the following:
6A02 Autism spectrum disorder
6A02.0 Autism spectrum disorder without disorder of intellectual development and with mild or no impairment of functional language
Description: All definitional requirements for autism spectrum disorder are met, intellectual functioning and adaptive behaviour are found to be at least within the average range (approximately greater than the 2.3rd percentile), and there is only mild or no impairment in the individual's capacity to use functional language (spoken or signed) for instrumental purposes, such as to express personal needs and desires.
All index terms:
Autism spectrum disorder without disorder of intellectual development and with mild or no impairment of functional language
Asperger syndrome
Asperger
Asperger disorder
Autism spectrum disorder without disorder of intellectual development and without impairment of functional language
It appears that the official term for the condition is "Autism spectrum disorder without disorder of intellectual development and with mild or no impairment of functional language" that's a mouthful but a generally good technical description whilst Asperger syndrome is included as an alternative / unofficial / popular / colloquial term.
The question now is whether the recent paper by Herwig Czech will impose pressure on the WHO to completely eliminate Asperger syndrome from the final publication of ICD-11.
