- Dr. Catherine Lord, as reported by NYT reporter, Amy Harmon, A Specialists’ Debate on Autism Has Many Worried Observers , New York Times, January 20, 2012
Persons with ID represented " the vast majority " of persons with autistic disorder according to CDC autism expert Dr. Yeargin-Allsopp. The DSM-IV addition of PDD-NOS and Aspergers reduced that figure to 41-44% according to recent CDC surveys. The DSM5 exclusion under Criteria A for social communication even where EVEN if all Critera A categories are otherwise exhibited will result in a further significant reduction in numbers of person with autism and ID. And that is the real aim of the DSM5 as Catherine Lord again confesses as reported in the Singer/SFARI article:
"Lord and her colleagues found that the DSM-5 is as sensitive as the DSM-IV, meaning it accurately identifies those who have autism. The DSM-5 criteria also have better specificity than those in the DSM-IV, meaning they can better distinguish between people who have autism and those who have other developmental disorders, the study found."
As set out above the real targets for exclusion from the autism spectrum under the DSM5 autism do-over are the intellectually disabled who are targeted by the addition of the "not accounted for by general developmental delay" disqualifying criterion in mandatory criterion A. Studies by J Matson have confirmed that substantial numbers, as many as 35.5%, of intellectually disabled who would meet DSM-IV autism criteria, will be excluded under the DSM5 criteria.
In the DSM5 the evolution of autism into Aspergers continues with the targeting for exclusion of the intellectually disabled. But no one cares. Not Dr. Lord, not Dr. Geraldine Dawson of Autism Speaks whose organisation has expressed concern over the possible impact of the DSM autism do-over on those at the HF end of the spectrum but not on the intellectually disabled. Not the New York Times and other major media who have worried over the possible HF exclusions. The exclusion of some HF is possible, the exclusion of many LF intellectually disabled is certain but apparently no one cares about the intellectually disabled and the impact this exclusion will have on them.
