Several years ago, I wrote a two part article on my thoughts about whether autism should remain in the DSM. Here’s what I came up with:

For now, we need to keep autism in the DSM, because it serves as the way for autism parents to help their children get the services they need to succeed in the world.

The current draft of the DSM V, available for review and comment, still includes autism – now referred to as Autism Spectrum Disorder (instead of  Autistic Disorder). However, the DSM V proposal recommends that Asperger’s Disorder and Pervasive Development Disorder Not Otherwise Specified (PDD-NOS) “be subsumed into an existing disorder: Autistic Disorder (Autism Spectrum Disorder)“.

As you might imagine, there has been a lot of discussion about this. I’m not really sure what I think of this change yet, there are so many aspects to consider:

• What is the impact to those already diagnosed with Asperger’s or PDD-NOS? In terms of available services? In terms of individual perceptions of self? Will they have to be rediagnosed, or will they be “grandfathered” in to an Autistic Spectrum Disorder?
• What is the impact to future diagnoses? Will there be fewer children diagnosed autistic, or more? Will a child who would have been diagnosed with Asperger’s or PDD-NOS be diagnosed as autistic? How will this affect funding of special education programs?
• Will parents accept a diagnoses of “autistic” for kids they believe are “too high functioning” to be autistic but whom they believe need the services that come with the diagnosis?
• How will special education programs be impacted? Will they be able to avoid a “one-size-fits-all” approach to treating “autism” as if it is a singular thing, or will they remain flexible enough to develop education plans based on the needs of individuals?

And more, many more.

It is the last of my bullets above that most concerns me. Anyone who is involved in special education – as a parent, student, teacher, or administrator – knows that even now Individual Education Plans (IEP) are typically anything but individual. (There are, of course, exceptions, but you will find many many more horror stories than success stories about IEPs.)

I agree with Roy Richard Grinker when he writes that “the stigma of autism is fading”, though I’m not sure I agree with him that this is happening “fast”. I also agree that across the three current diagnoses there is a lot of commonality, both in terms of symptoms and “treatment”.  But there are differences, and I think that having the three separate diagnoses emphasizes the “spectrum” – or, as Grinker calls it, a “continuum”.

My experience leads me to believe that many people don’t understand the concept of a spectrum unless they can clearly see the boundaries between the different layers of the spectrum. Only when you see a rainbow of light coming out of a prism can you see that white light includes all of those colors, and that each of those colors has its own unique properties. We still need this prism effect with autism.

We are making progress in understanding, but we still have a long way to go. So for that reason, I’m leaning toward the opinion that Asperger’s and PDD-NOS should stay in the DSM. At least for now.
