Expanding or
Limiting the Definition of Autism Could Be Harmful to Children
Health officials at the Centers for Disease Control (CDC)
announced last week that the rate of U.S. cases of autism had risen again to
about one in every eighty-eight children.
This represents a doubling of the figure in just five years. The CDC credited wider screening and better
diagnosis for the rise.
Conventional wisdom runs that most of the new diagnoses
come from the milder end of the autism spectrum – kids who, in the past, would
have been assigned learning disabilities or written off as anti-social nerds
and geeks. Others, such as Columbia University
Sociology Professor Gil Eyal, believe a significant number of new diagnoses
come from the more extreme end of the spectrum as well. His
2009 research found the rise in autism cases coincided with a drop in the
number of diagnosed cases of mental retardation.
Up to now, the diagnosis
of autism
has been blurry. That may be about
to change.

A more inclusive definition of autism confirms some
trends and defies others when crunching numbers. Autism remains five times as likely in boys
as girls. However, an increasingly large
proportion of children with autism have IQs of 85 or higher, contradicting a
past assumption that most autistic kids have IQs of 70 or lower. A study by the State University of New York
Upstate Medical University, entitled Macroeconomic
Environment During Infancy as a Possible Risk Factor for Adolescent Behavioral
Problems, found that mothers of autistic children are fifty-six percent
more likely to be under the poverty line.
Yet the widespread acceptance of autism as a spectrum
disorder may be the biggest breakthrough of all. Some applaud the new inclusivity for allowing earlier
diagnosis that has led an explosion in treatments and services for at-risk children. Others criticize including milder forms of
disorders, such as Asperger’s’ Syndrome, in the spectrum, arguing this tends to
trivialize very serious conditions suffered by other children.
Diagnosis of autism has long been controversial because,
up until now, it was simply a subjective evaluation, based on observation of social
awkwardness, fixated interests, and/or repetitive behaviors. There is no specific test for autism because
its physical causes (if any) are unknown.
That may be about to change.
A study just published in the New England Journal of Medicine by researchers at the University of
California, San Diego finds autism begins during pregnancy with subtle
disruption of the brain's frontal and temporal cortex. It identifies a mechanism of abnormal gene
activity causing overgrowth in the brains of autistic children that disappears
by adulthood but leaves lingering effects.
The study builds on the findings of other research
published by UCSD just last year. That research
found twenty-three percent of autism cases are linked to a specific combination
of antibodies in the mother's blood. Women with the antibodies are ninety-nine
percent likely to give birth to a child with autism.
Other experts may be busy attempting to limit the new
inclusivity in autism diagnosis. In
January 2012, Dr. Fred Volkmar, Director of the Yale Child Study Center, told
the New York Times a new definitions
of autism was about to come from the
American Psychiatric Association that would nip the recent autism surge “in the
bud.”
Such pruning would be just fine with Sociologist Frank Furedi,
formerly a professor at the University of Kent in Canterbury and the author of
many books, including Wasted – Why
Education Isn't Educating. Furedi
contends in The Telegraph that many parents – sometime subconsciously and sometimes deliberately
– are using autism as dispensation for poor performance from their children as
a result of normal hardships. He largely
dismisses the autism surge as an invention of convenience. “It is unlikely to be a genuine unprecedented
increase in autism, rather an institutional use of this condition to allow
people to get easier access to resources.”
It is easy to demonize Furedi as callous but he may be
making a useful point. Temple Grandin, possibly this country’s most
high-profile autistic person following a widely-viewed HBO biography, notes that while an autism diagnosis might help the
parents of at-risk children feel more supported and less alone, the children themselves
are not necessarily helped by the new emphasis so many are placing on autism. She frets in Salon magazine, “Now kids are getting fixated on their autism
instead of [other interests]. I’d rather
get them to fixate on that something that could give them a career.”
Grandin contends that many of history’s most famous
thinkers and doers probably fall somewhere on the autism spectrum. She once mischievously described society
without autistics as “A bunch of people standing around in a cave, chatting and
socializing and not getting anything done.”
Fellow autistic, writer Paul Collins, author of Not Even Wrong – Adventures in Autism, sums
up what is at stake even more cogently. “Autistics
are the ultimate square pegs, and the problem with pounding a square peg into a
round hole is not that the hammering is hard work. It's that you're destroying the peg.”
Right now, a lot of very smarts people are hammering away at the autism spectrum. Some are trying to smash it flat, elongating it to the greatest extent possible. Others are banging at the ends, trying to compress it back into a more manageable length. What all those bright minds are missing are the people in the middle, also with some bright minds of their own. Less important than their numbers or the degree of their differences is that fact that they are simply different from the rest of us and not deficient.
