The researchers went further to determine which children would be most likely to have their diagnosis changed from autism to SCD. The old, DSM-IV guidelines categorized individuals with autism into subtypes. These included autistic disorder, Asperger disorder and pervasive developmental disorder not otherwise specified (PDD-NOS).
Looking at these subtypes, Yale child psychiatrist and epidemiologist Young-Shin Kim and her colleagues found the following:
Of children previously diagnosed with PDD-NOS, 71 percent would now be diagnosed with ASD, 22 percent with SCD and 7 percent with another non-autism disorder.
Of those previously diagnosed with Asperger disorder, 91 percent would now be diagnosed with ASD, 6 percent with SCD and 3 percent with another non-autism disorder.
Of those previously diagnosed with autistic disorder, 99 percent would now be diagnosed with ASD and 1 percent with SCD.
"Until proven otherwise, the treatments for ASD and SCD should remain the same or similar," says Dr. Kim. "It's important for children moving to a SCD diagnosis - and to their families - that they continue receiving the interventions they would have received with an autism diagnosis under the earlier DSM-IV criteria."
"Our research team also wants to thank Autism Speaks and its donors for supporting this important work," she adds. In addition to two grants from Autism Speaks, the study also received support from the Brain Research Foundation, the Simons Foundation, and the National Institutes of Health.
