Autism Rising? Not According to Behavior Analyst Steve Taylor Who Proclaims That Autism Is 100% Genetic In Origin



Since my son was diagnosed with Autistic Disorder in 1998 the rates of diagnosed autism have risen dramatically from 1 in 500 to the current estimated rate of 1 in 88.  There is common acknowledgement that a substantial increase resulted from the DSM-IV changes which pushed acceptance of Aspergers as part of an autism spectrum.  Social factors such as increased awareness and availability of services under an autism label have also been cited.  Some purported autism experts  though have concluded that the dramatic autism increases are entirely attributable to diagnostic changes, increased awareness and the desirability for service reasons of an autism diagnosis. One such  autism expert is Behavior Analyst Steve Taylor who proclaims  in the Modesto Bee that "Autism isn't spreading, but the diagnosis is"

The dramatic increases have also taken place during years when genetic autism research received an overwhelming share of the autism research dollar. Calls for increased funding for environmental autism research by respected researchers like Hertz-Picciotto, Pessah, Landrigan, Birnbaum and others have not  tilted the balance dramatically away from the "its gotta be genetic mindset".  No study proving that the overwhelming increase in autism disorders is caused entirely by diagnostic change and increased social awareness has been produced.  No study producing a genetic explanation for all or even a significant number of autism disorders has been produced.  Very few environmental autism studies have been funded compared to genetic studies and yet the Steve Taylors of the expert autism community claim that there is no real increase at all.  

As they did with the refrigerator mothers theory of autism a few decades ago many of the world's autism "experts" embrace as an article of faith that autism isn't increasing.  Once again too the finger is pointed, at least in part, at parents ..... this time it is parents seeking services for their children as stated by Taylor in the  Modesto Bee:

"I'm still working with the same kind of kids, but everyone today seems to have autism. I met an area family for the first time recently and the 3-year-old I was there to help looked me in the eye and told me, "Go home." He's got autism, now.
No one can diagnose a complex disorder from a single interaction, but I'm going to spend months and maybe years working with this family to change behaviors that this rude boy would likely grow out of and, despite my best efforts, maybe make it worse.
For pure and understandable motives, parents still lobby for the diagnosis. An autism diagnosis brings more services.
The Stanislaus County Office of Education lists three pre-formal diagnostic (too young to diagnose) intensive classes of six to eight students as well as five elementary autism classes, which come with two full-time autism specialists.
A student with the same delays but not diagnosed as autistic doesn't usually get that kind of specialized support."
The only way Steve Taylor and the autism epidemic deniers could possibly be sure that the increases in autism rates are not real AT ALL is if autism disorders are not caused or contributed to by any environmental factors; that autism is entirely genetic in origin. Taylor is a true believer that autism is not increasing; that autism is 100% genetic in origin.  For those of us who lack Taylor's brilliant insights into the causes of autism we will have to wait for studies that actually provide evidence in support of his belief that autism rates are not really increasing at all.

Autism and Dr. Allen Frances' Question 5: Will Autism Research Be Possible After the DSM-5?


Dr. Allen Frances, chair of the DSM-IV Task Force
and principle investigator on the DSM-IV Field Trials

The last major changes to the "autism section" of the DSM occurred in 1994 with the grouping  of Aspergers, PDD-NOS and Autistic Disorder in the Pervasive Developmental Disorders section and are still cited by many as the primary basis for the massive increases in autism diagnoses over the past two decades.  No one doubts that a substantial amount of the recent increases are due to the DSM-IV diagnostic changes. The debate is over whether those changes account for the entire increase or whether they serve to mask or obscure the role of possible environmentally induced increases. With the DSM-5 soon to hit doctors' bookshelves the ability to develop a  reliable understanding of what is behind future changes in the numbers of autism disorder diagnoses will probably be lost forever,  or at least for the foreseeable future.  Epidemiological studies, already the subject of much debate, and much confusion,  could be rendered useless as tools for understanding what causes autism disorders. 

In his November 8, 2011 article, APA Responds Lamely to the Petition to Reform DSM-5re-posted by Brent Robbins PhD December 5, 2011 on the blog of the Society for Humanistic Psychology, Division 32 of the American Psychological Association, Dr. Frances, primary architect of the DSM-IV,  asks five questions about possible diagnostic inflation resulting from the DSM-5.  Question 5 asks the million dollar question:

5) Won't the many small, needless, and arbitrary changes in DSM-5 complicate future research efforts and make impossible the interpretation of data collected before versus after DSM-5?

If the answer to Dr. Allen Frances question is yes, as the Frances led DSM-IV experience suggests, then our ability to determine whether specific environmental factors are contributing to, or causing, autism disorders could be lost for another generation or more.

Autism Disorders On the Sidelines of the DSM5 Revolt


Several divisions of the American Psychological Association appear to be revolting against the American Psychiatric Association's DSM5.  A petition has been published on line.  In DSM5 in Distress Allen Frances, M.D., former chair of the DSM-IV Task Force and currently professor emeritus at Duke, summarizes the conflict between the warring APAs over the DSM5:

"Several divisions of the American Psychological Association have just written an open letter highly critical of DSM 5. They are inviting mental health professionals and mental health organizations to sign a petition addressed to the DSM5 Task Force of the American Psychiatric Association. You can read the letter and sign up at http://www.ipetitions.com/petition/dsm5/ It is an extremely detailed, thoughtful and well written statement that deserves your attention and support.

The letter summarizes the grave dangers of DSM 5 that for some time have seemed patently apparent to everyone except those who are actually working on it. The short list of the most compelling problems includes: reckless expansion of the diagnostic system (through the inclusion of untested new diagnoses and reduced thresholds for old ones); the lack of scientific rigor and independent review; and dimensional proposals that are too impossibly complex ever to be used by clinicians.

The American Psychiatric Association has no special mandate or ownership rights giving it any sovereignty over psychiatric diagnosis. APA took on the task of preparing DSM's sixty years ago because it then seemed so thankless that no other group was prepared or willing to do it. The DSM franchise has stayed with APA only because its products were credible enough to gain widespread acceptance. People used the manual only because it was useful.

DSM 5 has strained that credibility to the breaking point and (unless radically changed) will be much more harmful than useful. We have reached a turning point that will soon become a point of no return. A near final version of DSM 5 must be ready by next spring and all final wording will be set in stone within a year. Time is running out if DSM 5 is to be saved from itself."

Dr. Francis has been the most vocal and persistent critic of the DSM5.  His criticisms have a particular significance because of his former role as chair of the DSM-IV revision team. His observations about the DSM5 revolt picking up steam are noted by forensic psychologist Karen Franklin, Ph.D. in her blog commentary Psychologists' DSM5 Petition Catching like Wildfire, also published on Psychology Today:

An online petition by psychologists concerned about the lack of science underlying proposed changes in the American Psychiatric Association's Diagnostic and Statistical Manual (DSM) is taking off like wildfire, with more than 1,100 signatures as of this morning.

The blaze of interest is especially remarkable because the petition was launched without any publicity at all, and has gained traction solely through word of mouth.
The coalition of psychologists is publicly urging the American Psychiatric Association to reconsider the mental illness expansions and biomedical emphasis proposed for the fifth edition of the DSM, due out in 2013. The DSM-5 will reify disorders with little empirical support, lower the threshold for mental disorder, and foreground a purely biological approach to mental illness.

The coalition's online petitition comes on the heels of a similar public statement by the British Psychological Society, which I blogged about back in June.

The petition coalition expresses grave concern about the overemphasis on biomedical explanations for mental health problems, and the resulting overprescribing of dangerous psychiatric drugs"

The online petition expresses many concerns but makes no mention of the fundamental change to the autism disorders, grouping them together as one Autism Spectrum Disorder. Nor does it mention the exclusion of intellectually disabled persons from post DSM5 Autism Spectrum Disorder diagnoses.  The debates about autism causation are currently confused by many factors including the DSM-IV changes published in 1994.  Now, with fundamental changes in the definition of autism disorders, with the many becoming one, and with exclusion of intellectually disabled persons, epidemiological studies will once again be rendered limited if not worthless in helping us understand causes of autism.  The DSM5 rebels though make no mention of autism in their Petition.  

The DSM5 will have a huge impact on the Autism world,  if it is ultimately published AND accepted by psychologists. Autism is not a concern of the rebel forces though and Autism is left on the sidelines of the revolt.  The fate of many persons with autism disorders, and our understanding of autism disorders, will be significantly affected though by the outcome of the revolution.

Autism and the DSM-5's Unintended Consequence: The Return of Dr. Allen Frances



Dr. Allen Frances is engaged in an all out revolt against the DSM-5 revision process and those conducting the revision.  Underlying his revolt is an admission, at times express but always implicitly present, that if we have seen a series of false epidemics in areas such as Autism, ADD and childhood bipolar disorder then he, as much as anyone is responsible for those epidemics.  Dr. Francis oversaw the DSM-IV revisions on which he now puts great weight with his claims that we are now witnessing three false epidemics in autism, attention deficit and childhood bipolar.  Of late he has focused in particular on what he calls the false autism epidemic and in an attention grabbing catch phrase  the autism generation.

Having acknowledged his own failures Dr. Francis apparently feels free to say anything he wants about the DSM-5 revision process without first informing himself or without regard to unintended consequences for those whose lives are affected by those diagnostic descriptions. His comments about the allegedly false autism epidemic demonstrate that, contrary to message in his own sermons, he has not learned any lessons from his own previous DSM revision failures. In his speeches he proceeds in defiance of his own warnings that the APA DSM teams must proceed with caution when he offers unsubstantiated personal opinions without regard for their unintended consequence.

In The Autism Generation Dr. Frances offers a number of explanations for the increases in autism diagnoses, some of which undoubtedly play a significant but only partial role in explaining the startling increases in autism diagnoses:


The natural reaction to any plague is panic. Parents are now fearful that every delay in speech or socialization presages autism. Childless couples decide to avoid having kids. Parents with autistic children are desolate and desperate to determine its cause.


The British physician Andrew Wakefield’s vaccine theory became wildly popular among parents, many of whom began to withhold vaccination (thus subjecting their own and other children to the risk of entirely preventable, and sometimes serious, illnesses). Vaccination seemed a plausible cause because of the fortuitous correlation between getting shots and the onset of symptoms. Wakefield’s work has now been thoroughly discredited as incorrect and dishonest science. But fear of autism is so great, and the reactions to it so irrational, that in some circles Wakefield continues to be revered as a false prophet.


Other factors must be behind the sharp rise in the diagnosis. Before DSM IV, autism was among the most narrowly and clearly defined of disorders. Symptoms had to begin before age three and comprised a striking and unmistakable combination of severe language deficits, inability to form social relationships, and a preoccupation with a very narrow set of stereotyped behaviors. In preparing DSM IV, we decided to add a new category describing a milder (and therefore much more difficult to define and distinguish) form of autism, called Asperger's Disorder. This seemed necessary because some (still quite rare) children presented with more or less normal language development, but with grave social and behavioral difficulties. We knew that Asperger’s would likely triple the rate of autistic disorders to about 1 per 500-1,000, but this doesn't explain the new rate of 1 per 38.
A second possible explanation for the explosion in autism is that previously missed cases are now being more accurately diagnosed. This is probably a factor, but again only a minor one.
Perhaps, then, an environmental toxin is causing an epidemic outbreak of autism. This has been the most popular theory, but it, too, is a small factor, at best. There has been no sudden environmental change since 1994 to account for an explosion in rates. This doesn't entirely disprove an environmental vector, but it does make the odds quite remote – especially since there is a far more plausible explanation.

The most likely cause of the autism epidemic is that autism has become fashionable – a popular fad diagnosis. Once rare and unmistakable, the term is now used loosely to describe people who do not really satisfy the narrow criteria intended for it by DSM IV. Autism now casts a wide net, catching much milder problems that previously went undiagnosed altogether or were given other labels. Autism is no longer seen as an extremely disabling condition, and many creative and normally eccentric people have discovered their inner autistic self.

Where Dr. Frances came up with the idea that Dr. Andrew Wakefield is responsible for increasing autism diagnoses made by doctors and health care professionals is beyond me.  Attributing autism increases to panic stricken parents reacting years later to a the Wakefield article is pure nonsense. It seems like nothing more than a bizarre attempt to get   unthinking support for his opinions from those elements of the health care community who jump up and cheer whenever anyone attacks Dr. Andrew Wakefield. 

I know of no one who disputes the obvious fact that part of the increase in autism diagnoses is attributable to the addition of Asperger's Disorder to the pervasive developmental disorders or autism section of the DSM-IV.  As Dr. Frances acknowledges though  that  DSM-IV revision, together with more accurate diagnoses play only minor parts in explaining the increase.  

Dr. Frances then goes on to dismiss, in an extremely simplistic and superficial analysis substantiated only by his personal opinions,  the idea that environmental toxins are  possible sources of explanation for the autism increases.  Dr. Frances appears to be fundamentally ignorant of the CATS, the California Autism Twins Study, the positions statements of the IACC and Dr. Thomas Insel who has stated about the CATS findings:

"These new findings are in line with other recent observations supporting both environmental and genetic contributions to ASD, with the environmental factors likely prenatal and the genetic factors highly complex and sometimes not inherited" 


NIMH director Thomas R. Insel, M.D. 

Dr. Frances' dismissal of environmental toxins as possible contributors to the increases in autism diagnoses is inconsistent with current thinking and information concerning autism causation. It indicates that his opinions concerning autism should be considered carefully before being accepted.  When Dr. Frances goes on to refer to autism as a fad diagnosis and to talk about an autism generation he feeds the ignorance and prejudices of those who scowl at parents of autistic children when their children experience stress, even meltdowns, in public places.  He does not help, he harms, autistic children by spreading  misinformation about autism disorders.  He does so without providing any study or other authority beyond his own opinion for his dismissal of autism as a fad diagnosis. 

My son is 15 years old and he received his autism diagnosis 13 years ago in 1998.  That diagnosis resulted from consultations with a developmental pediatrician who conducted testing in sessions which lasted several months. We were referred to the pediatrician by our family doctor.  In all we began seeking an explanation for our son's obvious lack of development in areas like speech, play and family interaction in such games as peek a boo when my son was 1 year old in 1997.  We had not heard of autism at that time and we were not seeking a particular diagnosis, fashionable or otherwise.  We were not reacting in panic because of an article in a medical journal.  We wanted to know if our son was experiencing serious difficulties that would require specific medical help in order for him to grow and develop. We were exercising our parental responsibilities and caring for our son. 

Some of Dr. Frances' views and expressions of caution about the DSM-5 revisions seem to be based on real experience and common sense and I hope they are given serious consideration by the DSM-5 teams. I hope though that he follows his own direction to proceed with caution and limits his comments about autism to matters on which he can provide evidence and research findings.  I am sick and tired of professionals who dismiss parental concerns about their children's development and use them as tools to advance their own opinions. I assume that Dr. Frances, a respected psychiatrist, was placed in oversight of the DSM-IV because he contributed much to his profession and the people those professionals serve.  It will be better for autistic children though if Dr. Frances abandoned his stereotypical thinking about parents and educated himself about current autism research and thinking before expressing  unsubstantiated and possibly harmful opinions.
