Neurodiversity:an interview with Dr. Thomas Armstrong

Eight women representing prominent mental diag...

I recently read Neurodiversity: discovering the extraordinary gifts of Autism, ADHD, Dyslexia and other brain differences(you can read a mini review here) by Dr. Thomas Armstrong and came away impressed. In the book Dr Armstrong makes a  strong case for viewing the traditional disabilities from a differences perspective and to focus on the different strengths and abilities of the neurodiverse people. A recurring theme of this blog has been that autism and schizophrenia/psychosis are opposites on a continuum model as proposed amongst others by Christopher Badcock and Beranard Crespi. Dr Armstrong touches on this model in his chapter on autism, though that not central to his theis .

Dr Armstrong, was kind enough to answer a few questions for the benefit of our readers and these are reproduced below:

[SG] You have written a wonderful book on neurodiversity. Could you explain in brief, for the benefit of our readers, why neurodiversity has become so important in today’s context and why the focus on neurodiversity now when the differences that underlie the neurodiverse spectrum themselves are age-old?

[TA] I think neurodiversity is, as I’ve suggested in my book, “a concept whose time has come” because of the disability culture we live in. Almost half of us will have mental disorders sometime during our lifetime according to the National Institute of Mental Health, and even more will have “shadow syndromes” or minor versions of those disorders. When we get to the point where virtually everyone is seen as having a mental disorder to one degree or another, I think it’s time that we shift paradigms and use a diversity model instead of a disability model to account for those differences.

[SG] How much does neurodiversity owe to the Autistic advocacy movement and whether those beginnings are productive or counterproductive when one wants to bring other differences like mood or anxiety differences in the fold and talk about them as well?

[TA] I believe that the autistic advocacy movement deserves a great deal of credit for coining and developing the idea of neurodiversity. It’s rather amazing that a group of people who are known for their non-social attributes have made this contribution to our social understanding of brain differences. My hope is that my book Neurodiversity will help to broaden the concept of neurodiversity to include a wider range of abilities/disabilities. As far as I can see from looking at many sites online, there is an openness in the autism community to expanding the definition of neurodiversity beyond simply autism and Asperger’s syndrome.

[SG] Positive Psychology shares some of the same concerns as that of the Neurodiverse movement- the focus on strengths and what works and skepticism about the disease and pathology model- yet why hasn’t, in your opinion neurodiversity become center stage like the positive psychology movement has? Is it because in neurodiversity we are swinging the pendulum too much to the other side and perhaps blinding ourselves to underlying pathologies by claiming everything as differences?

[TA] No, I think it has to do with the credibility of the leadership of the Positive Psychology movement – spearheaded by a former president of the American Psychological Association and other famous professors of psychology. It’s essentially a top-down movement, whereas neurodiversity seems to me to be a bottom-up or “grass roots” movement that is coming from the people who are actually themselves neurodiverse. I don’t think of the neurodiversity movement as saying “we’re all different so leave us alone” I believe that attention needs to be given to ameliorating the disability part of neurodiversity, even as we focus the spotlight on the abilities.

[SG] For the benefit of our readers, if you could highlight the differences between the dimensional and categorical model of pathologies/differences. I believe neurodviversity leans towards the dimensional (continuum ) model. What can DSM V learn form the findings you have discussed in the Neurodiversity book? is a dimensional model of pathology a better one as compared to the categorical one? a necessary evil? or can the DSM mentality be done away with altogether?

[TA] One of the eight principles that I discuss in my book Neurodiversity is that everyone exists along “continuums of competence” with respect to a range of human processes including sociability, literacy, intelligence(s), attention, mood, and so forth. This is very similar to the DSM-V’s embracing of a dimensional perspective, and to that extent, I think the DSM-V is moving in the right direction. The problem is that the DSM-V will be a high stakes publication, and if people are put on a continuum from normal to pathological, the fuzzy line where normal becomes pathological (and vice versa) becomes very important, and may determine whether a person will be labeled with a disorder, given a drug treatment, and perhaps even stigmatized as a result. There’s a danger that many so-called normal people will be added to the ranks of the mentally disordered. Also, what’s missing from the DSM (in all its versions) is any kind of discussion of the positive dimensions of each of the disability categories.

[SG] Just like DSM, positive psychologists have come up with a list of character strengths and virtues as for ex can be seen on VIA signature strength website. Do you think those lists are sufficiently inclusive and give equal weighting to the special abilities found in neurodiverse individuals?

[TA] I think the VIA-IS (or Values in Action Inventory of Strengths) is a positive contribution to our understanding of human personality. It would be good to see someone take this inventory and map it onto the various pathologies taken up in the DSM-V. Wedding the two manuals would be a definite step in the right direction.

[SG] How much yours and your fathers experience of depression has been a driving force in your passion for psychology and especially instrumental in your focusing energies on the neurodiverse people.

[TA] I think it’s been very much a contributory factor. Seeing how my father’s depression affected our family’s functioning while growing up, and how my own depression has shaped my adult life, has been extremely influential in leading me to the field of psychology, and in trying to find the silver lining beyond the dark cloud.

[SG] People who are on extremes of the neurodiverse spectrum face immense stigma in our society. Your chapter on neurodiverstity in classroom talks about inclusive classrooms as you believe special classrooms for special ed programs end up labeling children. How practical you think is the concept of a neurodiverse classroom, esp in developing countries like India. Is a special ed class, even if it ends up labeling a child, better than no intervention at all and traditional classroom education only?

[TA] In a system based on traditional classroom learning, I believe that special education programs outside of the traditional classroom have a place, especially if they are using cutting-edge techniques for helping kids with special needs. But as an educational reformer, I am always pressing educators to expand beyond traditional learning environments for all kids, and when we utilize teaching methods that are good for all kids, we end up helping kids with special needs in the process.

[SG] Niche construction appears to be one of the special focus of your book. would you support or recommended special reservations in jobs/academics for neurodiverse people who may do especially well in those particular niches? For ex. would you favor a legislation that mandated for reservation for autistic people in computer testing industry. I’m thinking of cultural diversity guidelines in colleges, should we have similar neurodiversity guidelines too?

[TA] Are you talking about affirmative action for neurodiverse people? If so, then I believe there might be some merit in exploring how this might work. ([SG] note: yes, I was indeed talking about affirmative action; in India we typically refer to the issue as that of reservations!)

[SG] How did the writing of Neurodiversity enrich you as an individual. wWat can readers hope to take away from the book?

[TA] I wrote Neurodiversity while in the midst of a major depressive episode. At times I could hear myself saying “why are you looking at the strengths of these disorders, for God’s sake, when you know that they’re hell to deal with?” But there was another part of me, an intuitive part I believe, that instinctively believed it was important for me to bring strengths into the discourse about mental disabilities. I hope that readers will see this book as a supplementary guide to all the other books on disabilities that focus on the negatives. It’s important that we see both sides of the issue. We are, after all, whole human beings, with a great deal of complexity and richness. I hope that readers will take away a sense of this richness in the diversity of minds that make up humanity.

I would like to thank Dr Armstrong for taking some time off for the interview and would recommended the readers to read up some of his books, many of which focus on the special abilities and aptitudes of the neurodiverse people.

ADD

ADHD and creativity

ADHD has traditionally been conceptualized in terms of deficits- that of attention , impulse control or motor restraint; but the new neurodiversity paradigm forces us to take a more balanced look and acknowledge the strengths that the ADHD kid may have- divergent thinking, spontaneity and high energy and vitality.

That brings me to research by Cramform that shows that the symptoms that define ADHD/ADD- hyperactivity, impulsivity and distractability are just the negative connotation and spin put on some of the traits that define highly creative and gifted child-  the traits of Vitality, spontaneity and daydreaming/wandering phenotype.

But first things first. ADHD , as many of the readers will know , is defined by three primary symptoms- hyperactivity or the restlessness and fidgety or squirming behavior of the kid; impulsiveness or the inability to control impulses manifest in overt behavior like getting up in class and interrupting;  and distractibility where the kid ends up paying too much attention, even to stimuli that are extraneous and should be ignored, thus leading to fleeting attention! ADHD is a traditional classroom misfit and thus a traditional teachers nightmare. However, one should note that a traditional teacher is not too much impressed by the highly creative kid too, who proves to be a bit too much to placate and who doesn’t conform too easily.

But what could be the mechanism why ADD/ADHD must be so closely related to and resembling creativity traits as to be indistinguishable from it by behavioral symptoms alone? I believe dopamine and frontal cortex are the culprit. We have seen in the past that dopamine is related to creativity and we have seen that frontal cortex is related to creativity; and we have also seen that dopamine is related to ADHD. As a  matter of fact ADHD on a neurotransmitter level is characterized by dopamine’s quirky behavior , while on the neuroanotomic level is known by the late development of frontal cortex that is an inhibitor to other areas like motor areas and impulsive areas (basal ganglia and sub-cortical regions)  thus leading to symptoms of  impulsivity and hyperactivity. In creative people too, especially in divergent form of creativity, we see that creativity manifest itself when dopamine comes into play and when frontal regions give up their control of other regions of the brain thus making remote associations more likely.

Of course dopamine is not just involved in ADHD, but also in Psychosis and thus my theory of Autism and Psychosis as opposites would claim that ADHD is childhood form of psychosis and is opposed to Autism. There is already some support for that idea with autism and ADHD being discovered as opposites and with ADHD more common in bipolar probands.

The dual symptoms of ADHD as inattention and as hyperactivity/ implusivity are easy to conceptualize when one sees that one is trying to maximize predictive ability / minimize surprise and also maximize rewards by being flexible in one;s behavior and taking risks rather that persevering on the well trodden path. Both attention-allocation and action-selection are sensitive to dopamine and in one particular phenotype result in more leaning towards flexibility, distracatibility, hyper energy and arousal and more novelty and thrill seeking. The desire is to explore and not to exploit. The hunter rather than the farmer as per Hartman’s model. These same are characteristics of the creative phenotype- those touched with fire- and thus on the move literally or figuratively- always seeking new combination and ideas and exploring uncharted territory.

Perhaps its time we stopped negatively labellings the gifted, creative ADDers as difficult kids, but rather design and structure classrooms around them that bring their potential to the fullest and make them bloom fully. Lets not stifle the creativity. Lets not devalue the immense energy and joy these child exhibit and the creative potential they embody.

A brief history of autism

A mouse trap reader, using skribit, asked me to write a blog post about the history of madness; that is a dauting task, as she herself mentioned that Foucault wrote an entire book on the subject; so though I promise to write that post, in the meantime here is a post about the history of Autism.  After this , the next in series  would be a brief history of Schizophrenia.

Two Furies, from an ancient vase.
Image via Wikipedia

References to schizophrenia can be found since time immemorial, though the actual term and diagnosis is recent. It is believed that the people haunted by Furies of ancient Greek were actually schizophrenics suffering from delusions and hallucinations. As I contrast Autism and Schizophrenia it is apt that I start here; for similar to the rich historic al tradition, Autism can be equated with the ,blessed Fools’ of old Russia, “who were revered for their unworldiness. The apparent insensitivity to pain, bizarre behaviour, innocence, and lack of social awareness that these “Blessed Fools” showed, suggest that they may have had autism. ” (Happe). Similarly in almost all cultures one can find anecdotes and folktales about foolish boys (note that it is a boy and not a girl as autism has always been more prevalent in boys) who take what their mother said too literally- word for word , rather than figuratively and metaphorically or idiomatically.

The modern diagnosis of autism starts with Leo Kanner. Kanner published his first paper about  autistic children in 1943, the full text of which can be found here.  Some excerpts from the paper, which has many case studies , should help:

Since 1938, there have come to our attention a number of children whose condition differs so markedly and uniquely from anything reported so far, that each case merits – and, I hope, will eventually receive – a detailed consideration of its fascinating peculiarities.

The outstanding, “pathognomonic,” fundamental disorder is the children’s inability to relate themselves in the ordinary way to people and situations from the begining of life. Their parents referred to them as having always been “self-sufficient”; “like in a shell”; “happiest when left alone”;“acting as if people weren’t there”; “perfectly oblivious to everything about him”; “giving the impression of silent wisdom”; “failing to develop the usual amount of social awareness”;“acting almost as hypnotized.”T his is not, as in schizophrenic children or adults, a departure from an initially present relationship; it is not a “withdrawal”from formerly existing participation. There is from the start an extreme autistic aloneness that, whenever possible, disregards, ignores, shuts out anything that comes to the child from the outside. Direct physical contact or such motion or noise as threatens to disrupt the aloneness is either treated “as if it weren’t there”or, if this is no longer sufficient, resented painfully as distressing interference.


Eight of the eleven children acquired the ability to speak either at the usual age or after some delay. Three (Richard, Herbert, Virginia) have so far remained “mute.”In none of the eight “speaking” children has language over a period of years served to convey meaning to others. They were, with the exception of John F., capable of clear articulation and phonation. Naming of objects presented no difficulty; even long and unusual words were learned and retained with remarkable facility. Almost all the parents reported, usually with much pride, that the children had learned at an early age to repeat an inordinate number of nursery rhymes, prayers, lists of animals, the roster of presidents, the alphabet forward and backward, even foreign-language (French) lullabies. Aside from the recital of sentences contained in the ready-made poems or other remembered pieces, it took a long time before they began to put words together. Other than that, “language”consisted mainly of “naming,”of nouns identifying objects, adjectives indicating colors, and numbers indicating nothing specific.
Their excellent rote memory, coupled with the inability to use language in any other way, often led the parents to stuff them more and more verses, zoologic and botanic names, titles and composers of Victrola record pieces, and the like. Thus, from the start, language-which the children did not use for the purpose of communication-was deflected in a considerable measure to a self-sufficient, semantically and conversationally valueless or grossly distorted memory exercise.

When sentences are finally formed, they are for a long time mostly parrot-like repetitions of heard word combinations. They are sometimes echoed immediately, but they are just as often “stored”by the child and uttered at a later date. One may, if one wishes, speak of delayed echolalia. Affirmation is indicated by literal repetition of a question. “Yes”is a concept that it takes the children many years to acquire. They are incapable of using it as a general symbol of assent. Donald learned to say “Yes”when his father told him that he would put him on his shoulders if he said “Yes.”This word then came to “mean”only the desire to be put on his father’s shoulders. It took many months before he could detach the word “Yes”from this specific situation, and it took much longer before he was able to use it as a general term of affirmation.

The same type of literalness exists also with regard to prepositions. Alfred, when asked, “What is this picture about?”replied:”People are moving about.”

John F. corrected his father’s statement about pictures on the wall; the pictures were “near the wall.” Donald T., requested to put something down, promptly put it on the floor. Apparently the meaning of a word becomes inflexible and cannot be used with any but the originally acquired connotation.

But the child’s noises and motions and all of his performances are as monotonously repetitious as are his verbal utterances. There is a marked limitation int he variety of his spontaneous activies. The child’s behavior is governed by an anxiously obsessive desire for the maintenance of sameness that nobody but the child himself may disrupt on rare occasions. Changes of routine, of furniture arrangement, of a pattern, of the [form] in which every-day acts are carried out, can drive him to despair. When John’s parents got ready to move to a new home, the child was frantic when he saw the moving men roll up the rug in his room. He was acutely upset until the moment when, in the new home, he saw his furniture arranged in the manner as before. He looked pleased, all anxiety was suddenly gone, and he went around affectionately patting each piece. Once blocks, beads, sticks have been put together in a certain way, they are always regrouped in exactly the same way, even though there was no definite design. The children’s memory ws phenomenal in this respect. after the lapse of several days, a multitude of blocks could be rearranged in precisely the same unoganized pattern, with the same color of each block turned up, with each picture or letter on the upper surface of each block facing in the same direction as before. The absence of a block or the presence of a supernumerary block was noticed immediately, and there was an imperative demand for the restoration of the missing piece. If someone removed a block, the child struggled to get it back, going into a panic tantrum until he regained it, and then promptly and with sudden calm after the storm returned to the design and replaced the block.

The children’s relation to people is altogether different. Every one of the children, upon entering the office, immediately went after blocks, toys, or other objects, without paying the least attention to the persons present. It would be wrong to say that they were not aware of the presence of persons. But the people, so long as they left the child alone, figured in about the same manner as did the desk, the bookshelf, or the filing cabinet. When the child was addressed, he was not bothered. He had the choice between not responding at all or, if a question was repeated too insistently, “getting it over with”and continuing with whatever he had been doing. Comings and goings, even of the mother, did not seem to register. Conversation going on in the room elicited no interest. If the adults did not try to enter the child’s domain, he would at times, while moving between them, gently touch a hand or a knee as on other occasions he patted the couch. But he never looked into anyone’s face. If an adult forcibly intruded himself by taking a block away or stepping on an object that child needed, the child struggled and became angry with the hand or the foot, and became angry with the hand or the foot, which was dealt with perse [?] and not as a part of a person. He never addressed a word or a look to the owner of the hand or foot. When the object was retrieved, the child’s mood changed abruptly to one of placitidy. When pricked, he showed fear of the pin but not of the person who pricked him.

Note already that all the currently accepted DSM-IV characteristics of Autism like communicative difficulties, social difficulties and stereotyped or repetitive behavior are already well delineated by Kanner. Here one has to pause and note that autism and autistics were used from the social aloofness first observed and documented in schizophrenics by Kreplin and we seem to have come a full circle now by positing that Autism and schizophrenia are opposites on a continuum. It is also heartening to note that Kanner was also way ahead of his times by focusing on the deficit in ‘mentalizing’ in autistic kids.

Just a year after, Hans Asperger , published his paper on ASD kids, and it is remarkable that despite not knowing about each others papers they came with similar terminology (autistic ) to describe the children and agreed on more points than they disagreed on.

Asperger published the first definition of Asperger Syndrome, in 1944. In four boys, he identified a pattern of behavior and abilities that he called “autistic psychopathy”, meaning autism (self) and psychopathy (personality disease). The pattern included “a lack of empathy, little ability to form friendships, one-sided conversation, intense absorption in a special interest, and clumsy movements.” Asperger called children with AS “little professors” because of their ability to talk about their favorite subject in great detail. It is commonly said that the paper was based on only four boys.

Asperger and Kanner agreed as well as disagreed on many things:

Hans Asperger deserves credit for some very striking insights into autism: some insights which Kanner (1943) lacked and which it has taken us many years of research to rediscover. Before considering these particular observations of Asperger’s, it is worth noting the many features on which the two physicians agreed.
Kanner’s and Asperger’s descriptions are surprisingly similar in many ways, especially when one remembers that each was unaware of the other’s ground-breaking paper. Their choice of the term “autistic” to label their patients is itself a striking coincidence. This choice reflects their common belief that the child’s social problems were the most important and characteristic feature of the disorder. The term “autistic” comes from Bleuler (1908), who used the word (from the Greek “autos” meaning “self”) to describe the social withdrawal seen in adults with schizophrenia. Both Kanner and Asperger believed the social handicap in autism to be innate (in Kanner’s words) or constitutional (as Asperger put it), and to persist through life into adulthood. In addition, Kanner and Asperger both noted the children’s poor eye contact, their stereotypies of word and movement, and their marked resistance to change. The two authors report the common finding of isolated special interests, often in bizarre and idiosyncratic objects or topics. Both seem to have been struck by the attractive appearance of the children they saw. Kanner and Asperger make a point of distinguishing the disorder they describe from schizophrenia, on the basis of three features: the improvement rather than deterioration in their patients, the absence of hallucinations, and the fact that these children appeared to be abnormal from their earliest years, rather than showing a decline in ability after initially good functioning. Lastly, both Kanner and Asperger believed that they had observed similar traits—of social withdrawal or incompetence, obsessive delight in routine, and the pursuit of special interests to the exclusion of all else—in the parents of many of their patients.
There are three main areas in which Asperger’s and Kanner’s reports disagree, if we believe that they were describing the same sort of child. The first and most striking of these is the child’s language abilities. Kanner reported that three of his 11 patients never spoke at all, and that the other children did not use what language they had to communicate: “As far as the communicative functions of speech are concerned, there is no fundamental difference between the eight speaking and the three mute children” (Kanner 1943). While phonology (as demonstrated in accurate echolalia) and vocabulary were often excellent, Kanner concluded that of his 11 cases “In none …has language…served to convey meaning”. The picture in all is of a child with profound communicative difficulties and delay; in seven of the 11 cases so profound that deafness was initially suspected (but ruled out). Asperger, by contrast, reported that each of his four case study patients (and, by implication, most of the unspecified number of such children he treated) spoke fluently. Although two of his patients showed some delay, this was followed in both cases by a rapid mastery of language, and it is difficult to imagine any of his cases having been mistaken for deaf. All four cases, by the age of examination (between 6 and 9 years old), spoke “like little adults”. Asperger notes their “freedom” and “originality” in language use, and reports that two of his four cases had a tendency to tell “fantastic stories”.
Asperger’s description also conflicts with Kanner’s on the subject of motor abilities and co-ordination. Kanner (1943) reported clumsiness in only one case, and remarks on the dexterity of four of his patients. He concluded that “several of the children were somewhat clumsy in gait and gross motor performance, but all were very skilful in terms of finer muscle coordination”—in line with their success on the Seguin form board (in which dexterity plays a part) and their ability to spin objects. Asperger, by contrast, described all four of his patients as clumsy, and recounted their problems not only with school sports (gross co-ordination), but also with fine motor skills such as writing. This feature is part of a larger contrast in Asperger’s and Kanner’s beliefs. Kanner believed the autistic child to have a specific impairment in social understanding, with better relations to objects than to people: while his children showed “excellent, purposeful and ‘intelligent’ relations to objects” their “relations to people [were] altogether different”. Asperger, on the other hand, believed that his patients showed disturbances in both areas: “the essential abnormality in autism is a disturbance of the lively relationship with the whole environment” (Asperger 1944, translated in Frith 1991b).
The last area of disagreement in the clinical pictures painted by Asperger and Kanner is that of the child’s learning abilities. Kanner believed that his patients were best at learning rote fashion, but Asperger felt that his patients performed “best when the child can produce spontaneously”, and suggests that they are “abstract thinkers”. (Happe)

We now know that many of the insights of Asperger were correct especially for those suffering from high-functioning autism or Asperger’s syndrome.

A dark period of autism research was the ‘refrigerator mother‘ hypothesis , which posited based on a psychogenic theory that autism was due to bad parenting. The seeds of this theory can be traced back to Kanner, but Bruno Bettelheim gave it a prominence. this theory as now been widely debunked and discredited and caused undue suffering and guilt to a generation of parents.

Leading researchers in the field after these have been Uta Frith, Leslie, Happe and Simon-Baron-Cohen with his ‘mind-blindness’ theory.

Before concluding please visit the DSM criteria and reassess them as now autism, at least by me and many leading researchers, is conceptualized more as a continuum disorder. Hope the DSM-V has a continuum framework for autism.
