Farewell to Asperger’s?

dsm-stack One of the most fascinating conditions known to psychiatry may be headed for obsolescence. Asperger’s Syndrome will likely be folded into the more general category of Autism Spectrum Disorders in the next edition of the DSM–psychiatry’s diagnostic manual. PDD-NOS will likely share its fate.

The reason? “Asperger’s means a lot of different things to different people. It’s confusing and not terribly useful, ” says Catherine Lord, who heads the Autism and Communication Disorders Centers at the University of Michigan and who serves on the work group that is revising the manual.

The change is part of a larger overhaul of psychiatric diagnosis that will largely replace the old “you have it or you don’t” model of mental illness with a more modern view — that psychiatric disorders should be seen as a continuum, with many degrees of severity.

Autistic Savants

tammet_book1Savantism–an unexpected brilliance or skill in some defined area–is one of the more fascinating phenomena found on the autistic spectrum. According to some estimates about 10% of people with autism are savants, though I suspect this is mere guesswork.

England’s Daniel Tammet is perhaps the most famous living savant, having memorized and publicly recited the value of pi to 22,514 digits and authored a biography called Born on a Blue Day: Inside the Extraordinary Mind of An Autistic Savant. An interesting blog follows Tammet and savantism

At a recent conference, psychologist Ami Klin of the Yale Child Study Center described how children who do not develop the normal “expertise” in social interactions tend to develop expertise in the physical world. Very young children on the spectrum tend to stare for long periods of time at inanimate objects. I wonder if savantism might develop in part because brain power that’s not focused on developing complex social skills gets focused elsewhere.

Klin showed a slide of mathematic formulas written by one “very very depressed” young man with autism and an IQ of 147. He said that the patient had tried to express emotions in these equations. He then showed a formula, written by the young man, that said this:
If x=I find out there’s no God
And y=I find out that I can’t get a girlfriend
and z=I kill myself

A Clash of Viewpoints: Disability vs. Disease

Educators tend to see autism as a disability. Their strategy—as with children who are deaf, blind or learning disabled—is to shore up the child’s strengths and teach strategies to mitigate weaknesses that will likely last a lifetime.

Parents, however, tend to see autism as a disease—with the potential for a cure. This clash of viewpoints leads to all manner of misunderstandings and is at the very heart of the autism wars.

Fueling the fires and confusion is the idea occurring in both the lay and professional literature that children can “recover” from autism. O. Ivar Lovaas made this claim in his seminal 1987 paper in the Journal of Consulting and Clinical Psychology, where he reported that 9 of his 19 young subjects “recovered”, after intensive early treatment with applied behavior analysis, “achieving normal educational and intellectual functioning.” Stanley Greenspan claims his Floortime method can also bring this result. And, in the pop literature, one finds numerous tales of miraculous cures, the latest from actress Jenny McCarthy.

In seems indisputable that some kids do very, very well and may even appear symptom-free, especially with early intervention: but did these kids have full-scale autism to begin with, or something milder? Unfortunately, you can’t travel back in time and run an ADOS test (currently the gold standard for diagnosing the condition). When Lovaas’ associate Tristram Smith attempted to replicate his mentor’s study in 2004, he found that the kids who did the best had PDD-NOS, as opposed to full-spectrum autism.

Language matters. The word “recovery” can distract from the hard work required to help a child with autism. Thinking instead in terms of a disability puts the focus on the here and now instead of the cure around the corner. Amanda Mazin, a Ph.D. candidate at Teachers College who also teaches a methods class on teaching kids with autism, told me this: “Things go better when parents understand the disability and make their peace with dealing with it… They reorient their homes and their lives get easier.” And, she adds, once you get down to the business of addressing the disability, you can be amazed by the progress a child will make. “You don’t know what they are capable of, which is actually very exciting.”

It’s interesting that one of Lovaas’ old associates, Ron Leaf, said much the same thing. The term “recovery”, he noted, was borrowed from the literature on alcoholism. (If that’s true, Lovaas should have said “in recovery”!) “I don’t believe in the cure model,” said Leaf. “The analogy I use is stroke victim: with good occupational therapy, speech therapy and early intervention you can get good recovery. Whether not they “recover,” they can learn an awful lot.”
