This is the second of three reports from the 2011 annual meeting of the Maryland Association for Behavior Analysis (MABA).
As higher functioning children with ASD progress and succeed, their diagnosis may be questioned. In my son’s case, he was diagnosed in Infants and Toddlers days as having Asperger’s Syndrome. By elementary school, he had responded so well to early intervention that school staff couldn’t see it and believed he had ADHD all along. ASD, as you may know, is the only disorder where if you improve you never had it in the first place.

Once we had more thorough-going assessments done in the process of transferring him to a private special needs school, we learned they were both partly right. He would be most succinctly described by an Asperger’s diagnosis, based on how he presents today. But he doesn’t meet criteria because he had speech delays before age 3. So back then, he should have been diagnosed with autism. He has progressed so far, he now doesn’t meet criteria for autism. He does meet criteria for ADHD, but it doesn’t begin to explain all his needs. It takes several pages of specific learning disabilities to paint the rest of the picture.
Since we have experienced how blurry the boundary between Asperger’s/high-functioning autism and ADHD can be, I was very interested when Dr. Leonard Green presented at MABA this year about one factor which may be blurring the line. Green, a professor of behavioral psychology at Washington University in St. Louis, discussed one of the diagnostic criteria of ADHD – impulsivity.
