Self-Stimulatory Behaviors (A.K.A Stimming)



Mmmm --- beta-endorphins.





What is Stimming?

Stereotypy or self-stimulatory behavior refers to repetitive body movements or repetitive movement of objects. These movements are used solely to stimulate one’s own senses. This behavior is common in many individuals with developmental disabilities; it appears to be most common in children and adults with autism. It is important to note that not all self-injurious behaviors are considered to be self- stimulatory. Self-injurious behavior can also be communicative (see below).

What are some symptoms of stimming?
Stimming symptoms include: gazing at a wall or fixating on an object; repetitive body movements such as rocking back and forth; repetitive movement of objects, such as turning on and off light switches.

Here are some stereotypical stimming behaviors.

Visual: Staring at lights or ceiling fans; repetitive blinking; moving fingers in front of the eyes; hand-flapping, gazing at nothing in particular; tracking eyes; peering out of the corners of eyes; lining up objects; turning on and off light switches.

Auditory: Vocalizing in the form of humming, grunting, or high-pitched shrieking; tapping ears or objects; covering and uncovering ears; snapping fingers; making vocal sounds; repeating vocal sequences; repeating portions of videos, books or songs at inappropriate times.

Tactile: Scratching or rubbing the skin with one’s hands or with another object; opening and closing fists; tapping surfaces with fingers.

Vestibular: Rocking front to back; rocking side-to-side; spinning; jumping; pacing.

Taste: Placing body parts or objects in one’s mouth; licking objects.

Smell: Sniffing or smelling people or objects.

Why might my child be engaged in stimming?

Children with Autism Spectrum Disorder engage in stimming for a variety of reasons. One explanation is that it releases opiate-like substances in the brain called beta-endorphins, which can produce either a euphoric or anesthetic effect. Others believe that stimming could be due to the mechanism that provides: (a) an extra dose of internal stimulation for children with ASD who feel under-stimulated or (b) a feeling of tranquility for children who feel overstimulated.

Children who are hypersensitive, or overly sensitive to stimuli, may engage in stimming because they want to reduce their current level of stimulation, whether they perceive their environments as too loud, bright or crowded.

Children who are hyposensitive, or under-responsive to stimuli, may demonstrate the opposite effects: stimming may actually increase arousal. They may engage in self-stimulatory behaviors that provide them with an extra dose of sensory excitement, such as flapping or spinning, licking toys, sucking on household objects, or standing at sinks and running their hands under cold water.

In extreme instances, stimming may take on the form of self-injurious behavior. Examples include head banging, eye poking, and handing biting. Not all self-injurious behaviors are considered self-stimulating. Self-injurious behavior can also be communicative; children may hit their heads because they are frustrated and unable to tell their parents or caretakers what they want.

How might I help treat my child’s stimming?

Evidence suggests that the combination of positive reinforcement for functional responses with deceleration techniques (i.e extinction or over-correction) may provide an effective means of reducing self-stimulatory behavior and will help teach appropriate replacement behaviors.

Clay Marzo: In His Element

Clay Marzo is a prodigy in the water, but on land he struggles to keep up

by Alyssa Roenigk. ESPN the Magazine, September 7, 2009
It's been less than 48 hours since Clay Marzo was in the water, but that feels like a lifetime. Two days ago, while surfing near his home on the northwest shore of Maui, Marzo wiped out and was dragged across the razor-sharp reef. The cuts on his stomach are deep, the pain intense. Today, a warm October Wednesday, he can't even lie on his board.


Injury days are rare for Marzo, which is fortunate because time out of the water is debilitating. Not because of the physical pain -- that he can handle. But because on land Marzo struggles to communicate, to fit in, to breathe. All his life, he has struggled in social situations, and two years ago he finally found out why. Marzo, 20, suffers from Asperger's syndrome, a high-functioning form of autism. "I always knew something was different about me," says Marzo, his aqua eyes avoiding contact, the movements of his long, lean body visibly less fluid on land.


Different like this: The wiring in Marzo's brain makes it difficult for him to perform certain normal functions, such as reading facial expressions or recognizing social cues. As a result, simple acts of meeting people, attending parties and doing media interviews -- all requirements for a professional surfer -- are painful in a way that the cuts on his abdomen are not. In crowds, Marzo feels overwhelmed and exhausted. At group dinners, the stress of trying to follow multiple conversations causes headaches and nausea. Because he has difficulty coping with others, he's had a hard time making friends. People have called him strange and weird and, often, much worse.


But there's a flip side to his AS, a "benefit" of the condition that many with Asperger's have used to their advantage. The condition allows Marzo to laser-focus on a single activity, turning his greatest challenge into his greatest asset. Most people get bored after an hour or two of the same activity. Not Marzo. When he surfs, he goes into a zone, focused and lost at the same time. He calls an eight-hour surf session, with no breaks for food or water, "the perfect day." He'll then spend eight more hours watching video of his session, replaying each wave, over and over.

Sean DaveyMarzo has learned that the very thing holding back is also what makes him great.

Long before his Asperger's was diagnosed, Marzo and his parents recognized the paradox of his personality. In school he had trouble sitting still, comprehending directions or understanding what he read. "I could connect, could focus, if I really liked something," Marzo says. "But if I didn't, I couldn't focus at all." He'd flap his arms when he was anxious and rub his hands together when he was excited -- called stimming by autism specialists. He'd spend hours alone, obsessing over seashells or baseball cards. He was hypersensitive to sound and touch and would leave the table midway through family dinners or disappear to his room during the excitement of Christmas morning. When his routine was altered, especially if it kept him out of the ocean, he turned moody.


"Now I know those were all typical behaviors of someone with Asperger's," says Marzo's mom, Jill, a massage therapist. But for years, all the Marzos knew was that Clay best understood the world through the prism of surfing. They knew that's where he thrived, so Jill and husband Gino, who works in construction, nurtured his talent. "Clay is alive in the water," Jill says. "When he's not in the ocean, he is uncomfortable in his own skin."


In water, Marzo was a prodigy. He won a state swimming title at 10, and at 14 he caught the eye of execs at Quiksilver with his board skills. Marzo's older half-brother, Cheyne Magnusson, had a Quik sponsorship and recommended his kid brother, saying, "He's the real talent. He's the real deal." Marzo sealed the deal by sending a self-edited video of himself surfing local Maui spots to Strider Wasilewski, the company's team manager.


Wasilewski was instantly impressed. While most teen surfers are mastering bottom turns and cutbacks, Marzo was doing tailslides, reverses and controlled boardslides on the lip. "I'd never seen a kid at that age do those things," Wasilewski says. "Some of what he did was mind-blowing at any age. It was like someone had sent me the instructions to create the first nuclear bomb. I knew I'd received a package that would change the face of surfing."


A few months later, Wasilewski invited Marzo on a trip to the Mentawais to film Young Guns II, a surf video featuring hot up-and-comers Dane Reynolds, Fred Patacchia and Ry Craike, as well as nine-time world champ Kelly Slater. Marzo left quite an impression. "Clay is a freak on a surfboard," Slater says. "He does things people don't even think of. He just sees the wave his own way." In the water, he was relaxed and talkative. But on the boat, he'd walk away from people in midconversation, disappear at important moments and take others' cell phones and towels without asking, then lose them without apology. On the junior contest circuit, the story was the same; Marzo amazed with his flashy skills and offended with odd behavior. He has a catlike ability to stay up on his board, bending and contorting his body into seemingly impossible positions, and he was not shy about taking huge risks, often with disastrous results. Even when he just needed to ride out a wave to advance through a heat, Marzo would throw big tail-first snaps, land backward, or fly off the lip and spin a 360.

Sean Davey Though he struggles on land, Marzo often surfs nonstop for as long as eight hours.

"It was hard to watch," Gino says. "Other kids played it safe, but Clay went big on every wave." That in-the-moment attitude is another characteristic of people with Asperger's, who are so "in the now" that they seldom consider the consequences of their actions. When Marzo rode well, he was tough to beat. At 15, he won the men's open division at the 2005 NSSA championships, where he scored two 10s in the final. But his risk-taking almost upended his career.

As word of Marzo's free-surfing and tube-riding skills spread, requests for appearances, signings and group trips increased. But the more he was pushed into public situations, the more erratic his behavior became. He blew off many events and acted standoffish when he did show up. Marzo's quirks, previously overlooked because of his ability, began to make him a liability, especially when contest results slipped. At the 2005 world juniors, Marzo needed a 6. He could have won the contest by simply standing on a wave and doing a couple of turns. "Instead, he went for a crazy air and fell," says Quiksilver marketing director Jamie Tierney. "He lost."

To the outside world, Marzo looked like he didn't care -- about winning, about participating, about playing the game. "He was becoming a problem, and people wanted to let him go," Wasilewski says. "But I knew this kid wasn't stoned or stupid. He wasn't a spoiled teenager who didn't want to be there. I could see him freaking out inside. He was in pain." Wasilewski suspected Marzo might have some type of neurological disorder and found a self-test for Asperger's on the Internet. "It defined Clay to a T," he says. "I said, 'This is it. This is Clay's challenge. This is his gift.'"


Wasilewski and Tierney called Jill to ask if they could take Marzo for a formal evaluation and film the process. At first, she said no. But Wasilewski persisted, telling Jill: "Clay has a gift. He can be a surfing prophet. Or he can live in Honolua Bay surfing secret spots by himself." The Marzos finally said okay. "You want to protect your son, keep him safe," says Gino. "But we trusted that this was bigger than surfing. They wanted to affect peoples' lives."

In December 2007, during three days of exams with specialists Michael Linden and Chitra Bhakta in Southern California, Marzo underwent written tests, interviews, a family-history review and a QEEG test, which maps brain activity, showing where Marzo's brain was overaroused and underactive. Linden's conclusion: "Clay has Asperger's and symptoms of ADD and OCD."


Far from being upset, Marzo and his parents were relieved by the diagnosis. For Marzo, identifying his condition was a release that allowed him to embrace the two sides of his life. He now understands why social situations remain a daily challenge yet he can surf like few others in the world. The diagnosis has also brought a measure of respect from the surf world, an understanding of his genius. For example, because Marzo has spent so much time in the water, experiencing and studying the motion of waves, his peers believe he understands aspects of surfing that they may never comprehend -- that Marzo is to surfing what Einstein was to science and Mozart was to music. (Some experts believe both men, known for social awkwardness and single-minded brilliance, had Asperger's.) "It's a gift," Marzo says. "With surfing, with the way I see the world, with everything. It's definitely my gift."

Doomas/A-FrameYou can see Marzo surf in the documentary Clay Marzo: Just Add Water.

In the two years since the diagnosis, Marzo has been learning to bridge the gap between the calm of the water and his chaos on land. He attends biweekly therapy sessions, which teach him how to both recognize and give social cues and help him maintain calm in group situations. He has also scaled back his competition schedule. Instead of trying to qualify for the world championship tour, he focuses on video trips and photo shoots. "In surf culture, we've always had misfits and oddball characters," Tierney says. "So why would we ask a kid who's not a contest robot to become one? Clay is so much more interesting than that."


When he does compete, Marzo chooses events carefully. He went to the Quiksilver Pro in late August, in Puerto Escondido, Mexico, because the water is warm and feels like home, the surf big and barreling, and the break familiar -- he was on the team that won X Games gold on those waves in 2007. The competition wasn't nearly as much of a draw as the chance to surf barrels in a spot worth leaving home for. Yes, he notched one of just two perfect 10s at the event. And, yes, he won his first pro contest with a confident, calculated, patient display of surfing. But his performance is almost beside the point. For Marzo, the trip to Puerto was simply about feeling whole, about riding waves, about surfing. It's always been about the surfing.

Marlene Behrmann: Connecting Autistic Behavior to Brain Function

Autism is a disorder that is well known for its complex changes in behavior -- including repeating actions over and over and having difficulty with social interactions and language.

Connecting these behavioral patterns to an underlying neural deficiency is imperative for understanding what gives rise to autism, to developing better measures for diagnosing those along the Autism Spectrum Disorder and designing more effective treatments.

However, even given our significant advances in understanding how the brain works, there hasn't been evidence to tie autistic behavioral patterns together with corresponding neural functions. Until now.

A team of researchers -- including myself and colleagues from Carnegie Mellon University, the University of Pittsburgh, New York University and the Weizmann Institute of Science -- were interested in trying to understand on a basic neural level what happens inside the brain that might give rise to the altered behaviors in autism. Instead of focusing on the more complex behaviors, we set out to uncover and measure fundamental neural responses -- the patterns of brain activation in individuals with autism compared to those without.

Using an fMRI at Carnegie Mellon's Scientific Imaging and Brain Research Center, we scanned the brains of 14 adults with autism and 14 without while these individuals responded separately to visual, auditory and touch stimuli. We looked at the way the most elemental part of the brain's cortex responded to these simple stimuli.

In typical individuals, every time they saw the same visual stimulus, they had an almost identical response in the primary visual system. The stimulus drove normal visual systems in the same way time and time again. So, the question was whether we would see the same kind of consistent responses in the visual, auditory and somatosensory, or touch, cortices and within autism. It was our belief that any alteration in brain response we saw would be a very powerful indication of a major characteristic of autism.

It turns out that in all three of the primary cortices -- visual, auditory and somatosensory -- we did not see the typical response trial after trial in the individuals with autism. Instead, we saw considerable variability -- sometimes a strong response, sometimes a weak response. The fact that we did not see precise responses in autism was a really important result. It suggests that there is something fundamental that is altered in the cortical responses in autism. This variability in the brain response might also possibly explain why individuals with autism find visual stimulation, touch and sound to be so strong and overwhelming.

We know from genetic research that many of the neurobiological changes that occur in autism have to do with changes at the level of the synapse, the way that information is transmitted from one neuron to another. What these results -- that autistic adults have unreliable neural responses -- does is begin to allow us to build a bridge between the kind of genetic changes that may have given rise to autism in the first place. It cracks open a new avenue of research which has a good potential to be highly informative in understanding the connection between the neurophysiology and the behavioral patterns in autism.

While this particular study involved high functioning autistic adults and fMRI, we are now running follow-up experiments using EEG. This method which will give us even more detailed information about the neural responses and will allow us to test individuals across the autism spectrum and across different age groups so that we can gain further understanding of this unreliable neural response profile. And, because unreliable neural activity is a general property that could have a profound impact on how many brain systems function, it could underlie not only autism but a range of cognitive and social abnormalities including epilepsy and schizophrenia.

We are at the tip of a huge iceberg here; further research to fill in the details of exactly how this unreliability happens is essential for accurately diagnosing and treating autism and other disorders. At places like Carnegie Mellon University, which established a Brain, Mind and Learning initiative to build from its excellence in psychology, computer science and computation to continue to solve real world problems, these types of research projects are a priority. Our ongoing collaborations with Center for Autism Research at the University of Pittsburgh, and with ABIDE, which shares autism imaging data from top research facilities around the world, are crucial for working together to make sure we have all of the scientific resources possible to conduct high quality research.

My Obsessive Reading

I have an "indexing gene." I love checklists and reference data. I used to catalogue the creative credits for my favorite comic books, in pencil, on 3" x 5" index cards, during the Anchorage Fur Rendezvous dogsled races televised in the mid-seventies. I thought it was fun. Like most collectors, I would also make ultra-detailed "want lists" of missing, desired issues, and reading lists of favorite authors.

For a time in the nineties, I joined legendary comic fan Jerry Bails' indexing apa (amateur press association), apa-i. I 've contributed to the online Grand Comic Book Database., Askart, and other databases -- the ultimate versions of my old catalog card system.

These days, when I finish a nonfiction book, I write down the title and author(s) in a notebook. Sometimes I forget, but usually I record the books soon after reading. In true OCD fashion, I have to actually finish a book in order to record it. Partially finished books don't count. Believe it or not, just seeing the title/author information again helps me recall much of what I've read.

I originally read popular science and math books for the nonfiction genre, but after the 2008 financial crisis meltdown, I realized I knew nothing of business, and went on a business, economics, and investing book jag. Then in 2010, I shifted gears again to the current trend of mainly psychology and neuroscience reads. The "Behavioral Economics" business books made a nice bridge to these psychology books. I think my "psychology phase" is winding down now. What's next? Probably learning theory.

For "extra credit," I have typed out my list of my obsessesive fact-based reading conquests. You might enjoy reading a few of them yourself, so I have roughly categorized them. Frankly, after typing out this list, I'm a bit blown away at how much material I've consumed so far, and this doesn't even count all the comics, art books, magazines, and crime novels. I'm sure I've also missed a few books that I forgot to record. Here's the list, alphabetized by author.

Opinion: An Immune Disorder at the Root of Autism

Talk about "thinking outside the box!" Medicalized parasites. Yow! Check out this NYT Opinion piece. That'd be hard to swallow.

Don't forget to swallow your whipworm. Excuse me while I yak up my coffee.

Opinion
by Moises Velasquez-ManoffThe NewYork Times Sunday Review, published: August 25, 2012


In recent years, scientists have made extraordinary advances in understanding the causes of autism, now estimated to afflict 1 in 88 children. But remarkably little of this understanding has percolated into popular awareness, which often remains fixated on vaccines.

So here’s the short of it: At least a subset of autism — perhaps one-third, and very likely more — looks like a type of inflammatory disease. And it begins in the womb.

It starts with what scientists call immune dysregulation. Ideally, your immune system should operate like an enlightened action hero, meting out inflammation precisely, accurately and with deadly force when necessary, but then quickly returning to a Zen-like calm. Doing so requires an optimal balance of pro- and anti-inflammatory muscle.

In autistic individuals, the immune system fails at this balancing act. Inflammatory signals dominate. Anti-inflammatory ones are inadequate. A state of chronic activation prevails. And the more skewed toward inflammation, the more acute the autistic symptoms.

Nowhere are the consequences of this dysregulation more evident than in the autistic brain. Spidery cells that help maintain neurons — called astroglia and microglia — are enlarged from chronic activation. Pro-inflammatory signaling molecules abound. Genes involved in inflammation are switched on.

These findings are important for many reasons, but perhaps the most noteworthy is that they provide evidence of an abnormal, continuing biological process. That means that there is finally a therapeutic target for a disorder defined by behavioral criteria like social impairments, difficulty communicating and repetitive behaviors.

But how to address it, and where to begin? That question has led scientists to the womb. A population-wide study from Denmark spanning two decades of births indicates that infection during pregnancy increases the risk of autism in the child. Hospitalization for a viral infection, like the flu, during the first trimester of pregnancy triples the odds. Bacterial infection, including of the urinary tract, during the second trimester increases chances by 40 percent.

The lesson here isn’t necessarily that viruses and bacteria directly damage the fetus. Rather, the mother’s attempt to repel invaders — her inflammatory response — seems at fault. Research by Paul Patterson, an expert in neuroimmunity at Caltech, demonstrates this important principle. Inflaming pregnant mice artificially — without a living infective agent — prompts behavioral problems in the young. In this model, autism results from collateral damage. It’s an unintended consequence of self-defense during pregnancy.

Yet to blame infections for the autism epidemic is folly. First, in the broadest sense, the epidemiology doesn’t jibe. Leo Kanner first described infantile autism in 1943. Diagnoses have increased tenfold, although a careful assessment suggests that the true increase in incidences is less than half that. But in that same period, viral and bacterial infections have generally declined. By many measures, we’re more infection-free than ever before in human history.

Better clues to the causes of the autism phenomenon come from parallel “epidemics.” The prevalence of inflammatory diseases in general has increased significantly in the past 60 years. As a group, they include asthma, now estimated to affect 1 in 10 children — at least double the prevalence of 1980 — and autoimmune disorders, which afflict 1 in 20.

Both are linked to autism, especially in the mother. One large Danish study, which included nearly 700,000 births over a decade, found that a mother’s rheumatoid arthritis, a degenerative disease of the joints, elevated a child’s risk of autism by 80 percent. Her celiac disease, an inflammatory disease prompted by proteins in wheat and other grains, increased it 350 percent.

Genetic studies tell a similar tale. Gene variants associated with autoimmune disease — genes of the immune system — also increase the risk of autism, especially when they occur in the mother.

In some cases, scientists even see a misguided immune response in action. Mothers of autistic children often have unique antibodies that bind to fetal brain proteins. A few years back, scientists at the MIND Institute, a research center for neurodevelopmental disorders at the University of California, Davis, injected these antibodies into pregnant macaques. (Control animals got antibodies from mothers of typical children.) Animals whose mothers received “autistic” antibodies displayed repetitive behavior. They had trouble socializing with others in the troop. In this model, autism results from an attack on the developing fetus.

But there are still other paths to the disorder. A mother’s diagnosis of asthma or allergies during the second trimester of pregnancy increases her child’s risk of autism.

So does metabolic syndrome, a disorder associated with insulin resistance, obesity and, crucially, low-grade inflammation. The theme here is maternal immune dysregulation. Earlier this year, scientists presented direct evidence of this prenatal imbalance. Amniotic fluid collected from Danish newborns who later developed autism looked mildly inflamed.

Debate swirls around the reality of the autism phenomenon, and rightly so. Diagnostic criteria have changed repeatedly, and awareness has increased. How much — if any — of the “autism epidemic” is real, how much artifact?

Yet when you consider that, as a whole, diseases of immune dysregulation have increased in the past 60 years — and that these disorders are linked to autism — the question seems a little moot. The better question is: Why are we so prone to inflammatory disorders? What has happened to the modern immune system?

There’s a good evolutionary answer to that query, it turns out. Scientists have repeatedly observed that people living in environments that resemble our evolutionary past, full of microbes and parasites, don’t suffer from inflammatory diseases as frequently as we do.

Generally speaking, autism also follows this pattern. It seems to be less prevalent in the developing world. Usually, epidemiologists fault lack of diagnosis for the apparent absence. A dearth of expertise in the disorder, the argument goes, gives a false impression of scarcity. Yet at least one Western doctor who specializes in autism has explicitly noted that, in a Cambodian population rife with parasites and acute infections, autism was nearly nonexistent.

For autoimmune and allergic diseases linked to autism, meanwhile, the evidence is compelling. In environments that resemble the world of yore, the immune system is much less prone to diseases of dysregulation.

Generally, the scientists working on autism and inflammation aren’t aware of this — or if they are, they don’t let on. But Kevin Becker, a geneticist at the National Institutes of Health, has pointed out that asthma and autism follow similar epidemiological patterns. They’re both more common in urban areas than rural; firstborns seem to be at greater risk; they disproportionately afflict young boys.


In the context of allergic disease, the hygiene hypothesis — that we suffer from microbial deprivation — has long been invoked to explain these patterns. Dr. Becker argues that it should apply to autism as well. (Why the male bias? Male fetuses, it turns out, are more sensitive to Mom’s inflammation than females.)

More recently, William Parker at Duke University has chimed in. He’s not, by training, an autism expert. But his work focuses on the immune system and its role in biology and disease, so he’s particularly qualified to point out the following: the immune system we consider normal is actually an evolutionary aberration.

Some years back, he began comparing wild sewer rats with clean lab rats. They were, in his words, “completely different organisms.” Wild rats tightly controlled inflammation. Not so the lab rats. Why? The wild rodents were rife with parasites. Parasites are famous for limiting inflammation.

Humans also evolved with plenty of parasites. Dr. Parker and many others think that we’re biologically dependent on the immune suppression provided by these hangers-on and that their removal has left us prone to inflammation. “We were willing to put up with hay fever, even some autoimmune disease,” he told me recently. “But autism? That’s it! You’ve got to stop this insanity.”

What does stopping the insanity entail? Fix the maternal dysregulation, and you’ve most likely prevented autism. That’s the lesson from rodent experiments. In one, Swiss scientists created a lineage of mice with a genetically reinforced anti-inflammatory signal. Then the scientists inflamed the pregnant mice. The babies emerged fine — no behavioral problems. The take-away: Control inflammation during pregnancy, and it won’t interfere with fetal brain development.

For people, a drug that’s safe for use during pregnancy may help. A probiotic, many of which have anti-inflammatory properties, may also be of benefit. Not coincidentally, asthma researchers are arriving at similar conclusions; prevention of the lung disease will begin with the pregnant woman. Dr. Parker has more radical ideas: pre-emptive restoration of “domesticated” parasites in everybody — worms developed solely for the purpose of correcting the wayward, postmodern immune system.

Practically speaking, this seems beyond improbable. And yet, a trial is under way at the Montefiore Medical Center and the Albert Einstein College of Medicine testing a medicalized parasite called Trichuris suis in autistic adults.

First used medically to treat inflammatory bowel disease, the whipworm, which is native to pigs, has anecdotally shown benefit in autistic children.

And really, if you spend enough time wading through the science, Dr. Parker’s idea — an ecosystem restoration project, essentially — not only fails to seem outrageous, but also seems inevitable.

Since time immemorial, a very specific community of organisms — microbes, parasites, some viruses — has aggregated to form the human superorganism. Mounds of evidence suggest that our immune system anticipates these inputs and that, when they go missing, the organism comes unhinged.

Future doctors will need to correct the postmodern tendency toward immune dysregulation. Evolution has provided us with a road map: the original accretion pattern of the superorganism. Preventive medicine will need, by strange necessity, to emulate the patterns from deep in our past.
