Recovering From Autism Possible, Study Suggests
Jan. 15, 2013 -- The idea that some children recover from autism remains controversial, but new research lends credibility to the notion.
The National Institutes of Health-funded study included children, teens, and young adults who received a diagnosis of autism early in life but moved off the autism spectrum as they grew older.
Recovered or Misdiagnosed?
In earlier work, longtime autism researcher Deborah Fein, PhD, and colleagues at the University of Connecticut concluded that as many as 1 in 5 kids on the autism spectrum can recover to the point where they are no longer considered autistic.
But skeptics have claimed that the children the researchers identified as "optimal outcome" -- a phrase Fein prefers to "recovered" -- were simply misdiagnosed or had a very mild form of autism early in life.
To address this criticism, Fein and colleagues had an expert in the diagnosis of autism review the early diagnostic reports of 34 people with a prior diagnosis of autism, along with those of 44 people with high-functioning autism, and 34 people who had never received a diagnosis of autism.
But the autism diagnosis was deleted from the reports along with any information that would give the diagnosis away, Fein says. And the reviewer had no knowledge of the current status of the children and young adults in the study.
Autism Recovery Possible, Researcher Says
She says the reviewer identified all 34 of the optimal-outcome participants as originally autistic, based on their early diagnostic records, and all 34 of the typically developing participants as non-autistic.
Compared to those in the high-functioning autism group, those in the optimal-outcome group did show fewer social deficits in early childhood, but they were just as likely to have problems communicating and just as likely to engage in repetitive behaviors -- two characteristic early signs of autism.
When the researchers examined the current status of the optimal-outcome participants, who ranged from 8 to 21 years old, they exhibited none of the typical signs of autism, including problems with language, face recognition, communication, and social interaction.
The study appears today in the Journal of Child Psychology and Psychiatry.
