Identify and explain possible reasons for the increase in the number of individuals who are being identified as having ASD.

What will be an ideal response?


Ans: Clinicians are evaluating and diagnosing individuals more accurately, including individuals with milder forms of the disability that would have gone undiagnosed previously. Special education legislation has mandated early intervention and specialized services, and bring more individuals with ASD to the attention of the public schools. In addition, IDEA added a separate category for autism; individuals who were previously labeled as intellectually disabled, learning disabled, or emotionally disturbed are now being appropriately identified as having autism. There is greater public awareness of ASD resulting from increased attention in the popular press and other types of media. Parents are bringing their concerns to the attention of professionals. Changing diagnostic criteria used to identify autism spectrum disorders may also account for the increasing prevalence data. Regardless of the explanations put forth, it seems safe to conclude that an authentic increase in the number of children with ASD is occurring.
