O<\/span>ne of the most famous stories of H. G. Wells, \u201cThe Country of the Blind<\/a>\u201d (1904), depicts a society, enclosed in an isolated valley amid forbidding mountains, in which a strange and persistent epidemic has rendered its members blind from birth. Their whole culture is reshaped around this difference: their notion of beauty depends on the feel rather than the look of a face; no windows adorn their houses; they work at night, when it is cool, and sleep during the day, when it is hot. A mountain climber named Nunez stumbles upon this community and hopes that he will rule over it: \u201cIn the Country of the Blind the One-Eyed Man is King,\u201d he repeats to himself. Yet he comes to find that his ability to see is not an asset but a burden. The houses are pitch-black inside, and he loses fights to local warriors who possess extraordinary senses of touch and hearing. The blind live with no knowledge of the sense of sight, and no need for it. They consider Nunez\u2019s eyes to be diseased, and mock his love for a beautiful woman whose face feels unattractive to them. When he finally fails to defeat them, exhausted and beaten, he gives himself up. They ask him if he still thinks he can see: \u201cNo,\u201d he replies, \u201cThat was folly. The word means nothing \u2014 less than nothing!\u201d They enslave him because of his apparently subhuman disability. But when they propose to remove his eyes to make him \u201cnormal,\u201d he realizes the beauty of the mountains, the snow, the trees, the lines in the rocks, and the crispness of the sky \u2014 and he climbs a mountain, attempting to escape.<\/p>\n

Wells\u2019s eerie and unsettling story addresses how we understand differences that run deep into the mind and the brain. What one man thinks of as his heightened ability, another thinks of as a disability. This insight about the differences between ways of viewing the world runs back to the ancients: in Plato\u2019s Phaedrus<\/i>, Socrates discusses how insane people experience life, telling Phaedrus that madness is not \u201csimply an evil.\u201d Instead, \u201cthere is also a madness which is a divine gift, and the source of the chiefest blessings granted to men.\u201d The insane, Socrates suggests, are granted a unique experience of the world, or perhaps even special access to its truths \u2014 seeing it in a prophetic or artistic way.<\/p>\n

Today, some psychologists, journalists, and advocates explore and celebrate mental differences under the rubric of neurodiversity<\/i>. The term encompasses those with Attention Deficit\/Hyperactivity Disorder (ADHD), autism, schizophrenia, depression, dyslexia, and other disorders affecting the mind and brain. People living with these conditions have written books, founded websites, and started groups to explain and praise the personal worlds of those with different neurological \u201cwiring.\u201d The proponents of neurodiversity argue that there are positive aspects to having brains that function differently; many, therefore, prefer that we see these differences simply as differences rather than disorders. Why, they ask, should what makes them them<\/i> need to be classified as a disability?<\/p>\n

But other public figures, including many parents of affected children, focus on the difficulties and suffering brought on by these conditions. They warn of the dangers of normalizing mental disorders, potentially creating reluctance among parents to provide treatments to children \u2014 treatments that researchers are always seeking to improve. The National Institute of Mental Health, for example, has been doing extensive research on the physical and genetic causes of various mental conditions, with the aim of controlling or eliminating them.<\/p>\n

Disagreements, then, abound. What does it mean to see and experience the world in a different way? What does it mean to be a \u201cnormal\u201d human being? What does it mean to be abnormal, disordered, or sick? And what exactly would a cure for these disorders look like? The answers to these questions may be as difficult to know as the minds of others. Learning how properly to treat or accommodate neurological differences means seeking answers to questions such as these \u2014 challenging our ideas about \u201cnormal\u201d human biology, the purpose of medical innovation, and the uniqueness of each human being.<\/p>\n

N<\/span>ot coincidentally, the neurodiversity movement accompanies an apparent boom in the number of people with mental disorders, especially children. In locations monitored by the Centers for Disease Control and Prevention (CDC)<\/a>, the number of children with diagnosed autism spectrum disorders nearly doubled between 2002 and 2008, from one in 156 to one in 88. Autism was not even included in the American Psychiatric Association\u2019s Diagnostic and Statistical Manual of Mental Disorders<\/i> (DSM) until its third edition was published in 1980. Similar stories are true of other disorders. In the 1970s, ADHD was known as \u201cHyperkinetic Reaction of Childhood Disorder,\u201d and was not well known. Following revisions to the DSM, diagnosis has become increasingly common, especially in children. Psychiatrists\u2019 improved ability to identify and treat such conditions has much to do with their increased profile, though there is some question whether environmental factors may be responsible as well.<\/p>\n

A diagnosis of autism, ADHD, dyslexia, or depression does not necessarily mean that a patient has some definite set of observable traits. Each disorder exists on a spectrum, such that some cases are more evident than others \u2014 which complicates diagnosis as well as judgment of the patient\u2019s wellbeing. But as psychologist Thomas Armstrong writes in Neurodiversity<\/a><\/i> (2010; title changed in paperback to The Power of Neurodiversity<\/i>), there are generally at least a few characteristics of each disorder that hold across the spectrum and cause difficulty for those affected.<\/p>\n

Autistics, writes Armstrong, tend to be much better at understanding systems than understanding people. Perhaps the most famous person with autism is Temple Grandin, an animal scientist at Colorado State University, who wrote an autobiography on growing up with autism called Thinking in Pictures<\/a><\/i> (1995). To demonstrate the systematic thought process of autistics, Grandin describes an experiment conducted by Uta Firth, a British researcher on cognition:<\/p>\n\n\n

Joe, Dick, and a person with autism are sitting at a table. Joe places a candy bar in a box and shuts the lid. The telephone rings, and Dick leaves the room to answer the phone. While Dick is gone, Joe eats the candy bar and puts a pen in the box.<\/p><\/blockquote>\n\n\n

When the experimenter asks the autistic person what Dick thinks is in the box, the autistic person will say, \u201ca pen.\u201d Autistics do not know how to predict what others think.<\/p>\n

Consequently, autistics have great difficulty socializing. In his book An Anthropologist on Mars<\/a><\/i> (1995), neurologist Oliver Sacks describes this difficulty as a state of mental aloneness. Autistics cannot read emotions and do not know how to interact with other people, so they often make others uncomfortable. Grandin recounts that it has taken her years of practice and observation to learn how to introduce herself and converse, and that she still feels deeply uncomfortable doing it; the title of Sacks\u2019s book comes from Grandin\u2019s description of what it feels like to be around \u201cnormal\u201d people.<\/p>\n

For these reasons, autistics tend to enjoy working with computers and machines. The logic behind machines is simple; outcomes are consistent rather than dependent on the unpredictability of human emotions and the incompleteness of human knowledge. Furthermore, autistics often think about the world in terms of images rather than words. Grandin writes, \u201cmy imagination works like the computer graphics programs that created the lifelike dinosaurs in Jurassic Park<\/i>. When I do an equipment simulation in my imagination or work on an engineering problem, it is like seeing it on a videotape in my mind.\u201d Grandin also describes the \u201cvideo library in my imagination\u201d that includes \u201cvideo memories of every item I\u2019ve ever worked with,\u201d which she can retrieve and recombine with great precision.<\/p>\n

The processing of visual imagery and verbal thought, as Grandin notes, occur in different areas of the brain. In autistics, the visual area may become more active as compensation for a verbal deficit. People with autism also largely rely on visualization to understand concepts that are not inherently visual. In his 2007 memoir Born on a Blue Day<\/a><\/i>, Daniel Tammet, who is an autistic savant \u2014 someone with autism who possesses prodigious skills or capacities \u2014 describes the unusual way he experiences ideas:<\/p>\n\n\n

I see numbers as shapes, colors, textures and motions. The number 1, for example, is a brilliant and bright white, like someone shining a flashlight into my eyes. Five is a clap of thunder or the sound of waves crashing against rocks. Thirty-seven is lumpy like porridge, while 89 reminds me of falling snow.<\/p><\/blockquote>\n\n\n

Tammet, who has a remarkable talent for learning languages, also sees words as images: \u201cwhen I read a word or phrase or sentence written down, I close my eyes, see it in my head and can remember it perfectly.\u201d But his ability to remember chunks of words is very poor when he hears rather than sees them. This trait, common in autistics, often is a barrier to learning language, which most children acquire through listening. Their literal-mindedness also makes it difficult for autistics to understand idiomatic language: for instance, when Tammet first heard the phrase \u201cunder the weather,\u201d he thought, \u201cIsn\u2019t everyone under the weather?\u201d<\/p>\n

O<\/span>ne of the most common neurological diagnoses is Attention Deficit\/Hyperactivity Disorder. As described by Thomas Armstrong, psychiatrists and psychologists classify the three major symptoms of ADHD as hyperactivity, generally defined as an inability to sit still; impulsivity, or an inability to control one\u2019s actions; and inattention, or an inability to concentrate and a tendency to be easily distracted. As with autism, ADHD exists on a spectrum of severity and type. One type of ADHD manifests primarily as inattention; another primarily as impulsivity and hyperactivity; and the third main type manifests as all three kinds of behavior.<\/p>\n

Biologically, Armstrong explains, ADHD patients have disruptions within the neurological circuitry that connects the \u201crestraint and planning areas of the brain (the prefrontal lobes) and the emotional and motor areas of the brain (the basal ganglia and the cerebellum).\u201d The result is that people with ADHD suffer from impulsivity. Often, the parts of the brain that are disrupted in children with ADHD eventually develop normally, but lag behind the growth of children without ADHD by about three years.<\/p>\n

Counterintuitively, people with ADHD also suffer from under<\/i>-stimulation of the neurological system. They have a natural shortage of dopamine, a neurotransmitter that helps to control motor activity. It is this shortage of dopamine that creates a constant need for external stimulation; as Armstrong writes, \u201cwhat stimulates the average person is not enough for them. They need a higher dose of thrills and chills.\u201d This is why ADHD patients are often treated using psychostimulants, which increase dopamine in the brain and help stimulate the nervous system.<\/p>\n

Dyslexia, which literally means \u201cdifficulty with words, \u201d like ADHD is also fairly common. It affects between 5 and 20 percent of schoolchildren (depending on the diagnostic criteria) and seems to be caused by problems in the brain \u2014 specifically, in the left hemisphere, which is associated with logic, language, and arithmetic. According to Armstrong, the posterior left hemisphere is underactive in dyslexics, so that they tend to rely more on the anterior left hemisphere, which is associated with spoken language, and the right hemisphere, which is generally associated with visual-spatial skills, including facial and pattern recognition.<\/p>\n

Dyslexics have basic difficulties with reading and writing even short letters or compositions. This impairment exacts a painful toll on the psyche: in a culture where reading and writing are integral to the education of children, dyslexics face enormous challenges in coping with the basic requirements of school. Thomas G. West, a writer who himself had learning difficulties in childhood that he did not recognize until later in life, describes the lives of dyslexics and creative visual thinkers in his book In the Mind\u2019s Eye<\/a><\/i> (1991; not to be confused with Oliver Sacks\u2019s 2010 book The Mind\u2019s Eye<\/a><\/i>). West notes that patients commonly hide their dyslexia \u2014 sometimes even from themselves. One woman, \u201con learning in college of the basis of the problems that had tortured her during her early educational experience, wept for weeks.\u201d<\/p>\n

Perhaps the most well-known mental disorder, but the one that is least often viewed in terms of cognitive impairment or difference, is depression. Though also strongly associated with problems in the brain, the characteristics of depression are markedly different from those of autism, ADHD, and dyslexia. Neurological theories of depression hold that it is caused by deficiencies or imbalances in neurotransmitters, such as serotonin, which is thought to stabilize moods. The most common class of antidepressant medications is that of the selective serotonin reuptake inhibitors, such as Prozac, Zoloft, and Paxil, which increase serotonin levels between neurons by keeping the cells from reabsorbing it. This helps to maintain the level of activity and firing between the neurons.<\/p>\n

The symptoms of depression are all too familiar. Ludwig van Beethoven described the experience in an 1802 letter:<\/p>\n\n\n

With joy I hasten towards death \u2014 if it comes before I shall have had an opportunity to show all my artistic capacities it will still come too early for me despite my hard fate and I shall probably wish it had come later \u2014 but even then I am satisfied, will it not free me from my state of endless suffering? Come when thou will I shall meet thee bravely.<\/p><\/blockquote>\n\n\n

Beethoven would live another twenty-five years, but wrote this while suffering from deep depression, and while losing his hearing. Armstrong notes that, over the course of their lifetimes, nearly 13 percent of Americans experience major depressive disorders \u2014 classified as episodes of \u201clow mood, negativity, insomnia, and other indicators\u201d lasting for at least two weeks. Depression may last far longer than this, however, and often recurs for years or across a lifetime. Without psychotherapy or medication, people suffering from depression are at a high risk for harming themselves.<\/b><\/p>\n

T<\/span>he disadvantages of autism, ADHD, dyslexia, and depression are very real, and are what lead them to be considered disorders. But what those clamoring for cures often neglect, and what the term \u201cneurodiversity\u201d seeks to recognize, is that these disorders often also bring unusual abilities. For example, people with Asperger\u2019s syndrome (AS), a high-functioning type of autism, have an uncanny capacity to see details. They score higher than non-autistics on block-design tests, in which children are asked to use colored blocks to match a pattern given to them. They have better abilities to identify shapes, and are more likely to have prodigious talents, such as perfect pitch and highly accurate memories.<\/p>\n

Temple Grandin, the accomplished animal scientist with AS, has heightened visual-spatial abilities that grant her both a knack for envisaging the workings of machinery and a keen insight into the way that animals perceive the world. As a consultant for McDonald\u2019s, she has combined these talents to revolutionize the way that slaughterhouses are run, designing them to minimize the pain and fear that animals feel during processing. (Her work in this area was the focus of HBO\u2019s 2010 biographical movie Temple Grandin<\/a><\/i>.)<\/p>\n

Daniel Tammet, who also has AS, memorized over twenty thousand digits of pi and recited them in five hours. In his book, Tammet shows a diagram he used to memorize all of these digits. To most people, it would appear to just be a line graph with peaks and troughs, but Tammet associated these peaks and troughs with thousands of numbers. Many employers highly value such visual-spatial skills and orientation to detail. Thomas Armstrong describes Thorkil Sonne, the executive of a Danish software company, who searches for people with AS to serve as his software testers; Sonne\u2019s company benefits from their fastidiousness, amazing memory, and ability to concentrate.<\/p>\n

ADHD has potential benefits similar to those of autism. Although the notion is now perhaps too well-worn that our biological evolution lags behind our cultural development and our traits are best suited for an environment in which we no longer live, the idea is rather more plausible when it comes to ADHD. As Armstrong argues, people with what is now called ADHD would, in a hunter-gatherer setting, have been \u201calways moving, always vigilant,\u201d making them more wary of potential threats. They may have been more likely to be explorers or to discover new sources of food.<\/p>\n

The advantages ADHD might have had for our hunter-gatherer ancestors may seem ill-suited to an era that requires focus more than restlessness and vigilance. But in addition to the roving style of attention that often makes people with ADHD seem inattentive and restless, they also often possess an ability to focus for hours on specific activities or tasks that greatly stimulate or interest them. This \u201choming attention,\u201d as Armstrong calls it, is evident in \u201crock climbers negotiating steep mountain cliffs\u201d and \u201csurgeons engaged in twelve-hour sessions in the operating room.\u201d Certain professions actually demand characteristics that are much more prevalent in people with ADHD.<\/p>\n

People with dyslexia also have certain impressive skills generally lacking in non-dyslexics. They can easily recognize patterns and anomalies in patterns. They sometimes also possess greater visual-spatial abilities, including ease with visualizing objects and systems in three dimensions. Similar to the abilities of autistics like Temple Grandin, they can sometimes visualize machines in their mind, and can tinker with these images \u2014 changing, adding to, and subtracting from them. Dyslexics also tend to be especially creative, for, as Thomas G. West notes, \u201cone might see visual thinking, spatial ability, pattern recognition, problem solving, and related forms of creativity as linked together in a continuum.\u201d<\/p>\n

The creativity of dyslexics can enable them to make groundbreaking discoveries and, sometimes, to compensate professionally for their disability. West tells of Susan Hampshire, a dyslexic and an actress, who could not read scripts for the stage. Instead, she \u201cdevised a personal system of pictures, symbols and other cues to help her.\u201d Baruj Benacerraf, a dyslexic who is a former president of the Dana-Farber Cancer Institute and a Nobel laureate for his work in immunology, claims that his ability to visualize objects in three dimensions has greatly aided him in his research.<\/p>\n

While depression may seem simply dysfunctional, even this condition has some advantages for those who suffer from it \u2014 although it is difficult to establish a biological connection between the symptoms of depression and the special abilities of those who suffer from it. These abilities seem to be tied to the closely related disorder of manic depression. Kay Redfield Jamison, a psychiatrist who has written extensively on this topic, claims that manic depression is correlated with artistic temperament. In Touched with Fire<\/a><\/i> (1993), she recounts various studies showing that artists have far higher rates of manic depression than the general population. Jamison herself studied forty-seven British writers and visual artists who were highly accomplished in their respective fields, and found that 38 percent of them had been treated for a mood disorder, with most of those requiring medication or hospitalization. In the 1970s, another researcher at the University of Iowa examined thirty creative writers and found that 80 percent had had at least one episode of major depression. Jamison also cites Harvard psychologist Ruth Richards, who found that manic depressives, as well as their relatives, showed higher creativity than those without such family histories. The state of mania apparently heightens performance on certain creative tests, like the ability to produce original responses on word-association tasks. People in manic states also have increased abilities to produce rhymes, puns, and sound associations.<\/p>\n

Moreover, although many people assume that high creative production leads to elevated mood and low creative production leads to depression, studies seem to suggest that the order works in reverse: In what sounds like a clinical reformulation of the old notion of visitation from the Muses, Jamison found that \u201cwriters and artists … reported pronounced elevations in mood just prior to their periods of intense creative activity.\u201d Describing in Scientific American<\/i><\/a> the biological uniqueness of the manic-depressive mind, Jamison writes that it is \u201can alert, sensitive system that reacts strongly and swiftly. It responds to the world with a wide range of emotional, perceptual, intellectual, behavioral, and energy changes.\u201d<\/p>\n

T<\/span>here is a risk, however, in romanticizing the advantages of neurological disorder, and forgetting how painful and difficult these disorders can be. Romanticizing the connection between depression and artistic creativity, for instance, is not only dubious but also dangerous. Those heightened creative capacities are mostly associated with mania \u2014 which occurs only in some depressives, and even for them only intermittently. Not all depressives can write poetry or music, and the suffering of the artists themselves is at least as great as the works that it inspires. Even if there are special advantages conferred to the depressive mind, it seems problematic, even cruel, to apply the term neurodiversity<\/i> to those who need intensive therapy and medication simply to live and appreciate living.<\/p>\n

Similar cautions apply to our understanding of other neurological disorders. For instance, while there are obvious advantages to the heightened visual-spatial cognition of autistics, they have other traits that are much less clearly beneficial. Their nervous systems are hypersensitive, so that a simple knock on the door, tolerable to a normal child, can send shock waves through autistic children, much as a high-pitched fire alarm brings most people to plug their ears and recoil in pain. Temple Grandin tells of how, as a child, she was \u201cscared to death\u201d of balloons popping because the sound caused so much pain in her ears. Some autistic people, she says, can even sense the flicker of household fluorescent lights turning on and off sixty times every second.<\/p>\n

This sensitivity also extends to touch. Grandin \u201cwanted to experience the good feeling of being hugged, but it was just too overwhelming. It was like a great all-engulfing tidal wave of stimulation, and I reacted like a wild animal. Being touched triggered flight; it flipped my circuit breaker.\u201d But autistics still need physical contact and pressure in order to relax. Ultimately, Grandin built a contraption that provides this to her on a regular basis: called a \u201csqueeze machine,\u201d it puts pressure on her body and calms her nervous system. Oliver Sacks writes of Grandin that this device opens a door \u201cinto an otherwise closed emotional world and allows her, almost teaches her, to feel empathy for others.\u201d<\/p>\n

The difficulties of cognitive disorders are much more pronounced for individuals at the lower-functioning ends of the spectrums of these conditions. They are also harder to see \u2014 for these are just the individuals who tend to be much less vocal and visible in public discussions. The kinds of autism, for example, that the public most often hears about and sees depicted in media are usually the high-functioning ones, such as AS. Spokesmen like Temple Grandin or Daniel Tammet are able to write books about their condition; they adjust to society, find jobs, and learn to deal with people. The darker side of autism has few voices. Low-functioning autistics typically don\u2019t have blogs, books, or jobs.<\/p>\n

Many times, autistics grow up mute, rocking back and forth, flinging their hands up and down, unable to interact with others. Additionally, parents may shoulder great responsibilities when they have children with autism. Grandin writes that \u201cyoung children with autism need at least twenty hours a week of intensive one to one teaching by an adult.\u201d Parents must also pay for and participate in these sessions and deal with inexplicable temper tantrums, a child\u2019s inability to speak, and a child\u2019s social and emotional isolation, including difficulty in even hugging a parent. For many autistics, it seems condescending to label their conditions as cases to be appreciated under the rubric of neurodiversity rather than genuine disorder.<\/p>\n

ADHD also causes great frustration, as Blake E. S. Taylor recounts in his memoir ADHD and Me<\/a><\/i>, which he wrote during high school and published while a student at Berkeley. Taylor describes how, while taking a test on the Odyssey<\/i>, he found his mind wandering: \u201cI think about slalom racing down the packed powder, cold dry air on my face…. The distractions, like Circe, entice you and beckon you to daydream and enjoy yourself.\u201d Even during a test, which forces most young people to concentrate \u2014 and when concentration is most crucial \u2014 those with ADHD have little ability to control their thoughts and focus. Nor are these the kinds of distractions which most people would face for a fleeting moment when thinking about epic poetry; under many circumstances, they can be all-consuming.<\/p>\n

Another scene in Taylor\u2019s book vividly illustrates how far the impulsivity of a patient with ADHD goes beyond that of a normal child. One evening, Taylor watched as his sister played with a lighter. Though he had been taught safety procedures and understood the consequences and hazards of fire, he could \u201conly think of lighting something \u2014 anything \u2014 on fire to see what will happen.\u201d Taylor took a bottle of eyeglass cleaner and poured it on the flame \u2014 creating a blaze that nearly burned down his house. This is a classic story of ADHD: a child doesn\u2019t specifically want to cause mischief, but craves stimulation and lacks self-control.<\/p>\n

ADHD is perhaps the neurological disorder most closely associated with childhood: according to the CDC, 7 percent of Americans between ages six and eleven have been diagnosed with it. But it is not just children who confront these difficulties. In the Wall Street Journal<\/i>, adult ADHD patient Ali Bauman writes<\/a>, \u201cI had a messy bedroom and a string of minor accidents that I could never explain. I couldn\u2019t keep the house clean, pay bills, get things done on time. It wasn\u2019t that I didn\u2019t want to do it, I just wasn\u2019t capable of doing it.\u201d Over 4 percent of U.S. adults have also been diagnosed with ADHD.<\/a> Like children with the disorder, these adults often require medications like Ritalin to allow the focus required to keep their lives in order.<\/p>\n

Dyslexics may face even greater difficulties because of the relative lack of understanding the general public has about their condition. People with dyslexia often hide their disability because of the stigma and misunderstanding surrounding it; many people consider dyslexia and its symptoms to be a sign of stupidity, even though dyslexics have the same range of intelligence as the average population<\/a>. As Thomas G. West writes, \u201cthere are no rewards for revelation, and the penalties can take the most humiliating forms.\u201d<\/p>\n

Though dyslexics sometimes find their niche in society because of their visual-spatial and creative abilities, their disorder makes it difficult for them to perform the linguistic tasks necessary for passing through even elementary school. West recounts the stories of children who are laughed at by their peers for being unable to stand up and read fluently in class. Worse yet, teachers can fail to understand why certain students cannot read, and often end up putting dyslexics in special-education classes intended for children with below-average intelligence. All of these factors may take a heavy emotional toll, and can combine to keep dyslexic students from aspiring to greater goals \u2014 perhaps handicapping them for life.<\/p>\n

T<\/span>he question of whether autism, ADHD, depression, and dyslexia should be considered disorders or appreciated as a matter of neurodiversity is not, as it might appear, simply a matter of terminology or political correctness. For at stake is not only how people with these conditions should be regarded \u2014 pitied or perhaps ennobled \u2014 but whether and how they should be included, treated, or cured.<\/p>\n

For one group of advocates, the move to normalize neurological disorders is a form of gross medical irresponsibility \u2014 an ignorant act of cruelty rather than of toleration toward people who are suffering. Lenny Schafer, who has an adopted son with severe autism, in a recent issue of the online Schafer Autism Report<\/a> notes research finding that boys with autism are more likely to be bullied, and that obesity, hypertension, and diabetes are linked to the risk of autism. Schafer told New York<\/i> magazine<\/a> that \u201cit\u2019s like stealing money from the tin cup of a blind man when you say that it\u2019s not an illness.\u201d<\/p>\n

The difficulty, however, does not simply lie in whether to treat or not to treat. Even within the realm of treatment, the question remains whether to work with<\/i> or against<\/i> the unique traits of the individual. Thomas Armstrong, who has had years of teaching experience, including at the primary-school level, argues that this is a problem with special education under the current system. Special ed, he says, bases its approach \u201con deficit, damage, and dysfunction\u201d rather than \u201cstrengths, talents, and aptitudes.\u201d In other words, the purpose of special ed is to cater to the slower learners. But many of these \u201cslow\u201d learners actually have talents that should be nurtured by teachers. A primary goal for ameliorating the plight of children with neurological conditions, then, would be to change the perception of special ed as a place for people who are not smart. This means also changing the approach: the question should be less whether, say, autistics as a group are gifted or defective, and more how to recognize and work well with each individual\u2019s weaknesses and strengths \u2014 as an effective educational program should for any child.<\/p>\n

The questions of treatment, intended to benefit or change the lives of those already affected, are complicated by and easily confused with the more stark ethical questions of prevention and cures. Scientists have already identified many genes that contribute to neurological conditions, and are working to find more. For example, some variations of the dopamine receptor D4<\/sub> gene may be one of the factors that contribute to ADHD; and there is strong evidence that other disorders are heritable. Studies on the heritability of autism<\/a> show that it almost certainly has a genetic component \u2014 although researchers estimate that as many as a hundred genes may be involved. Thomas G. West claims that families share dyslexic traits. And genetic predisposition is believed to play a significant role in depression, too.<\/p>\n

The ultimate goal of this research, of course, is not simply to learn the causes of these disorders but to help eliminate them. Mark Daly, an associate professor of medicine at Massachusetts General Hospital, argues<\/a> that the \u201cpieces are in place\u201d to head in the direction of identifying gene variants and using that information to eventually develop more effective treatments \u2014 perhaps even by manipulating the genes in living patients. But pronouncements about such theoretical possibilities are prone to mislead about the immense pragmatic and ethical difficulties inherent in such an undertaking. And Armstrong, despite his sincere call for better understanding and appreciation of children with neurological disorders, scarcely explores in his book the practical difficulties and moral problems associated with manipulating human genetics.<\/p>\n

In the first place, we do not necessarily know how a cure would work for each individual person. The human body is not like a machine: tinkering with one part will not always have predictable consequences for the other parts. Because we are biologically distinct, subtle biological variations mean that every person\u2019s body will respond differently to the same treatment. This is especially true for psychiatric conditions, which involve not only our bodies but our personalities as well; a drug that is considered successful in a psychiatric context may only work for some modest fraction of patients, and provide only modest improvements. Complicating factors and side effects are often not well understood, and treatments are often based not on definite diagnoses, as in more traditional disease models, but on an unsystematic trial-and-error approach. This is why there are many different kinds of medications for any given neurological disorder. For ADHD, for instance, doctors can prescribe Ritalin, Adderall, Dexedrine, Cylert, or various other stimulants or combinations of stimulants.<\/p>\n

Treatment becomes even more complicated when it involves the manipulation of genes. Such treatment is still only hypothetical in human beings, and if it were to become possible would likely be extremely difficult and unpredictable. The role of individual genes in the development of traits and the functioning of an organism tends to be enormously complicated; one can only imagine how unpredictable the effects of manipulating the nearly hundred genes associated with autism would be. We need to understand not only how this would affect the autistic traits of a patient, but the other traits as well, which are far from neatly independent from each other in the first place.<\/p>\n

T<\/span>he likelihood that disordered traits are too enmeshed in the biological makeup of individuals to be targeted separately underscores the broader point made by many advocates that their disorders are integrated into who they are. Many of those who are born with these differences and are able to advocate for themselves are wary of research into eliminating their conditions, on the basis that it would eliminate much of what makes them them<\/i>. To search for a \u201ccure\u201d denies their distinctiveness as human beings.<\/p>\n

Disability rights advocate Ari Ne\u2019eman, who has AS and was appointed by President Obama to the National Council on Disability, argues in a 2010 interview with Wired.com<\/a> that the traditional focus of the autism community has been on \u201cnarrow questions of causation and cure.\u201d And the focus of the national dialogue on matters like the vaccine controversy has led to the exclusion of \u201cthe voices of the people who should be at the center: those who are on the [autism] spectrum ourselves.\u201d Rather than focusing on how to make a world where autistic people \u201chave the rights and support they deserve,\u201d more traditional activism has aimed to \u201ccreate a world where there aren\u2019t any autistic people.\u201d<\/p>\n

When asked whether he would take a pill to cure his autism, Ne\u2019eman replies that \u201cthat\u2019s an intensely silly question … predicated on the strange idea that there was or is a normal person somewhere inside me, hidden by autism, and struggling to get out.\u201d This response gets to the heart of the beliefs underlying the neurodiversity movement: these conditions are not simply disorders afflicting otherwise healthy individuals, but are integral parts of who these individuals are. These advocates hold that the way to address the problems they face is to change the world to make it more inclusive of them and their particular needs, not to change them to fit what the world sees as normal or appropriate.<\/p>\n

This point becomes disturbingly concrete when one considers that the more likely application for knowledge of genetic causes of these disorders will not be to find cures through genetic manipulation for existing patients, but rather to test and screen fetuses and embryos so as to eliminate before birth those that have a mental disorder. There is a telling precedent in the case of Down syndrome, which is already widely tested for in the womb, resulting in abortion for over 90 percent of fetuses with positive diagnoses<\/a>. As Ne\u2019eman has written in these pages, \u201cTo disability-rights advocates, this indicates a fundamental prejudice against the disabled\u201d (see \u201cDisability Politics<\/a>,\u201d Spring 2009).<\/p>\n

Might the same thing happen with fetuses with autism? Despite the activities of the neurodiversity movement, the inclination to consider neurological differences to be disorders or defects still predominates. So it seems quite plausible that the trend we see against fetuses with Down syndrome could expand to include fetuses with other sorts of brain differences, if similar tests for them were to become available. How might we decide at what point a case of neurological disorder becomes too severe to be acceptable and who will get to make such decisions? The precedent would leave these choices in the hands of parents \u2014 but, as Ne\u2019eman notes is already the case with parents who receive a prenatal diagnosis of Down syndrome, \u201cmany … are given patently false information about the characteristics of the people they are being encouraged to prevent.\u201d<\/p>\n

There is, of course, an immediate practical difficulty for such decision-making in the fact that, unlike the test for Down syndrome, new tests for other disorders are likely to provide far less certain results. The difficulty of predicting complex traits such as autism or depression based on genes or other biological factors easily detectable during pregnancy means that at best, such tests would likely only express a probability of certain neurological disorders, and would be even worse at predicting severity. Individual decisions of whether to abort would be muddled from the start, unable to rely on solid information that a child will or will not have a certain set of defects. Parents who abort a potentially defective fetus would likely have to face the possibility that their child would have suffered only mild abnormalities or none at all, while parents who choose only to carry to term fetuses that test sufficiently normal might still end up having to raise a child suffering from disabilities due to inadequate test results \u2014 a child they would have aborted had they correctly known his or her condition \u2014 with disturbing ramifications for how the parents might feel about and care for that child.<\/p>\n

Considered at the societal level, the question is: If we were able, would we move to eliminate large segments of the population and the different ways of experiencing the world that characterize them? Doing so would arise from a judgment that the lives of people with neurological differences are less worthy than the rest of ours \u2014 as is already clearly the judgment so many parents are making with respect to Down syndrome pregnancies.<\/p>\n

The cases of people with autism, dyslexia, ADHD, and depression who are able to lead successful, productive and well-adapted lives speak powerfully. Advocates with autism and other neurological differences say that they would never eliminate their singular traits \u2014 that those are much of what gives them their identity. Temple Grandin, Blake E. S. Taylor, Beethoven, and innumerable others show the kind of contributions such individuals are able to make to society. They show us how wrong we would have been were we to have tried to change them to be other than they are, or worse, never given these individuals a chance at life.<\/p>\n

The heart of the matter of neurodiversity is not the hypothetical question of how we might use genetic testing in the future, but the very immediate question of how we are to regard and treat those who are already here. And important though the high-functioning individuals are as examples, the worth of a life should not have to be justified by extraordinary achievements. One of the lessons of H. G. Wells\u2019s story is that the narrowness of our vision easily obscures the value of the lives of others, especially when they seem to us impaired.<\/p>\n

Every life has joy and triumph, pain and hardship, aspiration and frustration \u2014 all parceled out unequally, and this only in part because of the different biological hands we are dealt. In labeling certain individuals \u201cdefective\u201d or \u201cdisordered,\u201d we act in part to wall off some people as the unfortunate, tacitly claiming that the rest of us are whole, avoiding the truth that we are all flawed, struggling with deficiencies, working with and against aspects of ourselves we would like to overcome. In labeling others as \u201cdisabled,\u201d we must ask whether we are motivated by sympathy and compassion, or by fear and the difficulty of knowing the minds of others.<\/p>\n

But even as we should not pass judgment on the value of the lives of others, neither should we presume to know their pain and difficulties. In a way, the neurodiversity movement shares a premise with the movement to eliminate individuals with neurological differences: namely, it says that individuals are to some extent identical with and defined by their nameable neurological traits. But in both cases, there is a danger of focusing on abstractions instead of the uniqueness of each individual.<\/p>\n

We should celebrate the many treatments available for people who are suffering: anti-anxiety medications to help autistics, antidepressants for the depressed, Ritalin for people with ADHD, along with a wide variety of cognitive and behavioral therapies. The scientific community will and should continue to develop and improve these medications and therapies, especially for those who suffer on the extreme ends of the spectrums of neurological disorders.<\/p>\n

The struggle remains one of understanding not only the causes of neurological disorders, but also to what extent prevention and treatment means valuing or devaluing the lives of affected individuals. Perhaps progress in these areas will necessarily remain idiosyncratic \u2014 and we would do well to be wary of solutions presented as absolute \u201ccures.\u201d The line between difference, advantage, and suffering may not always be clear, and will be different for each individual, as will what counts as desirable treatment versus troubling manipulation.<\/p>\n

In considering the question of how to deal with the diversity of neurological conditions, we would do well to remember H. G. Wells\u2019s story, where \u201cnormal\u201d is a fluid term. Nunez thinks of the blind as abnormal, but so do they of him. That each human being is biologically unique is, in fact, the norm. These biological differences are, in turn, inextricably intertwined with the different ways we have of seeing and being in the world. Eliminating this rich biological and psychological diversity in the ostensible interests of ameliorating or preventing suffering would in the end diminish our humanity. It would make us less visibly like the country of the blind, but more like them in their prejudice. Rather than working to create another set of public labels, the real value of the neurodiversity movement may be in helping us to recognize that we each face challenges and opportunities \u2014 and that a decent society is one in which we are each able to strive to make the best of what we are given.<\/p>","protected":false},"excerpt":{"rendered":"
