New Medication Ineffective for Autistic Symptoms - 0 views

  • What this means, sadly, is that the only drug on the market which has FDA approval to specifically treat autism is risperdal - a medication which, like many others, can have problemmatic side effects. In addition, risperdal is only useful for a relatively small number of people overall.

NeuroLogica Blog » Dr. Laureys Admits Facilitated Communication Failure - 1 views

  • This is where the story gets interesting, and where it became an international controversy. Enter Linda Wouters – a speech therapist who uses facilitated communication (FC). She claimed that after months of training she could communicate with Houbens by sensing the subtle movements of his right hand, which he could use to direct her across a computer screen keyboard.
  • FC, unfortunately, is pure pseudoscience. It was introduced in the late 1980s as a wonderful new method for communicating with children with cognitive disorders, on the assumption that they were more verbally than mentally impaired. Many therapists were convinced, and many parents were overjoyed as their previously non-communicative children starting writing poetry expressing their love for their parents. (And there was also a dark side as some children, through FC, started reporting physical and sexual abuse by parents and caretakers.)
  • When people got around to actually testing FC scientifically it turned out, rather unequivocally, that all the communication was being done subconsciously by the facilitator – a phenomenon called the ideomotor effect. They were not just supporting the hand of their client, they were directing it. Well-designed studies showed that the facilitator was always doing all the communication. FC then shrank to a fringe phenomenon – but its adherents would not give up, and FC continues to this day (even sometimes in courtroom testimony), hoodwinking the unawares and having to be debunked all over again and again.

  • Regarding Rom Houben video showing Wouters performing FC with Houben clearly showed that he could not be doing the communication. In one video Houben was not even looking at the keyboard, and may not have even been awake. But in every video Wouters was moving his hand across the keyboard at unbelievable speeds – not even a neurologically intact person could direct another to keystrokes with such speed an accuracy by just moving one finger.
  • Laureys has now carried out those tests, and his results hold that it wasn’t Houben doing the writing after all. The tests determined that he doesn’t have enough strength and muscle control in his right arm to operate the keyboard. In her effort to help the patient express himself, it would seem that the speech therapist had unwittingly assumed control… In the more recent test, Houben was shown or told a series of 15 objects and words, without a speech therapist being present. Afterward, he was supposed to type the correct word — but he didn’t succeed a single time.
  • It is truly a scandal that FC is still around. Like homeopathy, therapeutic touch, and many similar medical pseudosciences – their persistence is not a failure of science, which has adequately shown them to be nothing but illusions, but rather of collective rationality.

Many people with autism are taking too many different things - 0 views

  •  
    Many people with autism are taking too many different things. If the person has been on the medication for a long time, it must never be abruptly stopped. The dosage should be reduced slowly. If you try a new drug for a few days or weeks and decide you do not like it, you can usually stop it; but it is best to check with your child's doctor.

A week ago, a new study published in the Archives of General - 0 views

  • The Howard Hughes Medical Institute describes how researchers using "high-throughput gene sequencing technology" were able to identify several de novo or spontaneous gene mutations in 20 children with sporadic autism spectrum disorders -- that is, their family members showed no other sign of autism.
  • The team identified 21 spontaneous mutations -- meaning they weren't inherited from either parent -- in the children's DNA. Eleven of these were mutations that would alter the protein encoded by the affected gene. In four of the 20 children, the researchers found mutations that were severe, some of which have been previously linked to autism, intellectual disability, and epilepsy.
  • one child had a mutation in the GRIN2B gene, which is crucial for neuronal signaling.
  • ...3 more annotations...
  • Another individual had an extra nucleotide in FOXP1, a gene that, along with its close relatives, has been heavily implicated in language defects.
  • These new findings support the 'multi-hit' model of autism, which suggests that having more than one mutation can cause or worsen symptoms of autism and other brain disorders. The different combinations of mutations may contribute to the heterogeneity in ASDs.
  • That such different combinations of genetic mutations contribute to a child being autistic could account for why individuals with an ASD diagnosis have some very similar, and very different, features.

What Do New Genetic Findings Mean to Families with Autism? - 0 views

  • reply from lead researcher Hakon Hakonarson:
  • The variant we detected at the 5p14 locus (common variant) has been present for a long time in the genome (most likely since man moved out of Africa) and this region is highly conserved between species which means that it is regulating gene expression and gene function (the CHD10 gene being the most critical one).
  • We know that the association is strongest in those individual who have the greatest abnormalities in social skills/interactions and those that show least interest in interactions; we have not detected any other characteristics yet, but we keep working on it.
  • ...2 more annotations...
  • Once we learn about this difference, we can then look for medications that block the consequences of the variant and once we make sure they are safe, we can then start testing these new medications in children who are at risk of developing autism, with the objective of preventing autism (i.e., avoid breakdown in connections between nerves and abnormality in brain connectivity).
  • Response: Yes, all of them could be tested in utero; we have identified 10 new variations (9 rare and 1 common) and we have replicated (and confired) four other once that were previously published (neurexin 1, contactin 4, 15q11 and 22q11). However, we do not have a yes or no answer as to whether the fetus will be autistic -- but if we are testing a fetus in an autistic family the value of the test is much higher.

Childhood Disintegrative Disorder, Autism/PDD: Yale Child Study Center - 0 views

  • Childhood Disintegrative Disorder This rather rare condition was described many years before autism (Heller, 1908) but has only recently been 'officially' recognized.
  • The condition develops in children who have previously seemed perfectly normal. Typically language, interest in the social environment, and often toileting and self-care abilities are lost, and there may be a general loss of interest in the environment. The child usually comes to look very 'autistic', i.e., the clinical presentation (but not the history) is then typical of a child with autism.
  • A special educator in Vienna, Theodore Heller, proposed the term dementia infantilis to account for the condition.
  • ...3 more annotations...
  • in most cases after even very extensive testing no specific medical cause for the condition is found. As with autism, children who suffer from this condition are at increased risk for seizures.
  • evidence suggest that it arises as a result of some form of central nervous system pathology.
  • Childhood disintegrative disorder is perhaps 10 times less common than more strictly defined autism

MedPie | Autism Among Somalis in Minnesota and Sweden: is it the Low Sunlight? - 0 views

  • High autism rates have been found in Somali imigrants living in Sweden and in Minnesota.  What does Sweden have in common with Minnesota, besides wolves and snow?  They are both at high lattitudes and get low sunlight, especially in the winter.  Swedish researchers have proposed that vitamin D deficiency may play a role in the high incidence of autism found among Somali immigrant children.  Vitamin D is made in the skin from sunlight. 
  • Several medical-cultural trends may have combined to produce vitamin D deficiency in pregnant women, infants, and children, possibly predisposing children to autism: widespread use of sunscreen and avoiding outdoor exposure during peak hours, and reduced consumption of fatty cold-water fish by pregnant women, due to fears of mercury contamination. 
  • Herndon et al report that children with Autism Spectrum Disorder consume significantly fewer servings of dairy products than children without ASD, although both children with ASD and those without were deficient in vitamin D.  Dairy products in the United States are supplemented with vitamin D.

News from the Associated Press - newsjournalonline.com - 0 views

  • Leo Lytel was diagnosed with autism as a toddler. But by age 9 he had overcome the disorder. His progress is part of a growing body of research that suggests at least 10 percent of children with autism can "recover" from it - most of them after undergoing years of intensive behavioral therapy.
  • She presented research this week at an autism conference in Chicago that included 20 children who, according to rigorous analysis, got a correct diagnosis but years later were no longer considered autistic.
  • Skeptics question the phenomenon, but University of Connecticut psychology professor Deborah Fein is among those convinced it's real.
  • ...10 more annotations...
  • Previous studies have suggested between 3 percent and 25 percent of autistic kids recover. Fein says her studies have shown the range is 10 percent to 20 percent.
  • But even after lots of therapy - often carefully designed educational and social activities with rewards - most autistic children remain autistic. Recovery is "not a realistic expectation for the majority of kids," but parents should know it can happen, Fein said.
  • The children in Fein's study, which is still ongoing, were diagnosed by an autism specialist before age 5 but no longer meet diagnostic criteria for autism. The initial diagnoses were verified through early medical records.
  • The researchers are also doing imaging tests to see if the recovered kids' brains look more like those of autistic or nonautistic children.
  • Imaging scans also are being done to examine brain function in formerly autistic kids.
  • Results from those tests are still being analyzed.
  • Most of the formerly autistic kids got long-term behavior treatment soon after diagnosis, in some cases for 30 or 40 hours weekly.
  • Many also have above-average IQs and had been diagnosed with relatively mild cases of autism. At age 2, many were within the normal range for motor development, able to walk, climb and hold a pencil.
  • Significant improvement suggesting recovery was evident by around age 7 in most cases, Fein said.
  • None of the children has shown any sign of relapse. But nearly three-fourths of the formerly autistic kids have had other disorders, including attention-deficit problems, tics and phobias; eight still are affected.

Autistic Aphorisms: Intelligence, Genius, and Autism - 0 views

  • Professor James Flynn has incorporated an interesting sidebar into his book What is Intelligence? In it he lists his seven choices for Western civilization’s greatest minds: Pythagoras, Plato, Aristotle, Archimedes, Newton, Gauss, and Einstein.
  • Hundreds of research teams, maybe even thousands by now, have so convinced themselves that intelligence must originate from inside our skulls, have so convinced themselves that only within networks of cranial neurons can be found the secrets to humanity’s growing mental capacity, that all have managed to overlook completely the far more plausible alternative—the one existing right before our very eyes.
  • It is time to reconsider that conventional wisdom, time to regard genius with a different set of eyes; for genius is not a function of greater intelligence, genius is the description of how intelligence grows.
  • ...11 more annotations...
  • Look at the content of any intelligence test—language, arithmetic, patterns, designs. What we measure with the aid of those I.Q. booklets are not the abilities we inherited from out our animal past, but instead their exact counterpart; we measure only those skills the species has been adding throughout all its history since. In some sense, an intelligence test measures the modernness of an individual; an intelligence test measures an individual’s ability to appropriate for himself the same set of skills the species has been appropriating as a whole—skills that do not find their origin in our biological nature, but instead owe their existence to the strange, brewing mixture of non-biological pattern, structure and form that has been rapidly taking shape all around us.
  • The unusual characteristics of humanity’s transformational individuals are not the result of their genius, they are genius’s prerequisite
  • But counter to prevailing wisdom, there are many autistic individuals—most likely a majority—who do make substantial progress by means of an alternative perceptual course, a course that allows them not only to navigate meaningfully their surrounding world, but also to assimilate, if somewhat awkwardly and belatedly, to the human species itself (and thereby explaining how autism, estimated to be present in nearly one percent of the human population, could go entirely unrecognized until as recently as sixty-five years ago).
  • all autistic individuals must crystallize their existence by means of this alternative perceptual course—it becomes, in essence, autism’s most salient feature.
  • The unusual behaviors and interests of autistic children—lining up toys, staring at ceiling fans, twirling, flapping hands repeatedly, fascination with knobs, buttons, switches, letters, shapes and digits, watching the same video again and again, singing the same song over and over—these activities betray a form of perception completely unlike that of most other children, a perception noticeably absent in social and biological focus, but also noticeably drawn to symmetry, repetition and pattern.
  • The unusual routines of autistic children are the natural, indeed the expected, mode of expression for a form of perception engaged primarily by the structural aspects of the non-social, non-biological world.
  • Autistic individuals would have been the first to notice the inherent structure contained in the natural world—the geometry of plants, the isomorphisms of natural objects, the logic of the celestial seasons—only they would have had motivation to embrace such form, only they would have had the need to perceive nature’s symmetry, repetition and pattern in order to form their cognitive grounding.
  • We know only bits and pieces about the four Greeks on Professor Flynn’s list, but filling in with the traits from the list’s more modern members, we can reasonably summarize all the unifying characteristics: late- or strange-talking, socially awkward, irascible, obsessed with structure, compelled by form, unusually—not necessarily greatly—intelligent.
  • The continuing medicalization of autism, the insistent demonization of autism’s spontaneous effect—these carry the danger of an unforeseen consequence. For the cure of autism will not be the end of a tragic brain disorder; autism’s eradication will not see the passing of a troubling mental disease. The removal of autism from the entire human species will produce only an ironic solution to the mystery of our expanding human intelligence, it will produce the ignoble end to the Flynn effect.
  • When confronted by data that runs counter to our accustomed way of seeing things, we as humans have but two choices: we can try to explain the results away, or we can adjust our perception of the experienced world. The former choice paves the all-too-common road of modern academic science; the latter, as described above, walks the more promising path of genius.
  • Autism is not a mental illness, not a brain disorder, it is instead the source of humanity’s changing perception of its experienced world; it is, with care and understanding, genius’s fertile soil.

Autism and early oxygen deprivation 2 | On the Brain by Dr. Mike Merzenich,Ph.D. - 0 views

  • Fraternal twins typically have different placentas, whereas identical twins share a placenta but have different cords. The blood supply, and pre-clamping susceptibility to anoxia, would surely be different.
  • As for the idea that one could statistically detect whether cord clamping is the problem, we can! Amish people do not clamp the cord until placental delivery, and they have no autism rate. The same is true in Somalia, but Somalian immigrants to westernized medical countries have high rates. Try to systematically find out autism rates and immediate cord clamping rates, on a country by country, or region by region basis. It is a task someone should get on immediately, but it will take a lot of effort.
  • An interesting discussion of the “Amish anomaly” re autism incidence has been provided by Dan Olmsted, who went to Amish Country to find the 150 or so individuals there who could be expected to be severely autistic. They aren’t there. He seems pre-disposed to believe that the difference lies with their non-vaccination. Many studies now show that this is unlikely. As David Blake points out, there is another difference in this population: In Amish birthing, by tradition, the cord is not clamped prior to placenta delivery.

  • The picture with autism in Somali children is a little murkier. It turns out that the incidence of autism is very high in children of Somali origin who were born in the US (several times higher than normal), while it appears to be very low in Somali children born in their native country. Again, vaccination has been identified as the likely cause by Somali parents and by many observers — but again, clamping follows placental delivery in Somalia, while the cord has been clamped without delay as a general practice in Minnesota, where a high incidence of autism in these children of Somali immigrants was first discovered.

New Study: Autism has Multiple Genetic Roots | Suite101 - 3 views

  • The study’s major finding was that children with ASD have significantly more CNVs affecting their genes than children without ASD. Children with ASD have 20 percent more CNVs in general, and 70 percent more CNVs impacting genes known to be associated with ASD or cognitive problems. Significantly, many of the genes that are affected control important functions such as cell proliferation and cell-to-cell communication.
  • Some of the newly discovered genetic variants are inherited, and are found in parents or siblings of children with them. Others, however, seem to have originated spontaneously in the affected child, and do not appear in other family members.
  • While these findings add significantly to the scientific understanding of the genetic and biological underpinnings of ASD, the immediate usefulness is limited. That’s because there are a very large number of CNVs, and each child shows a different pattern of genetic changes. Each of these changes is rare; no CNV showed up in more than one percent of the children studied.
  • ...3 more annotations...
  • “This will lead to a paradigm shift in understanding the etiology of autism,” says Stephen Scherer, a senior scientist at The Hospital for Sick Children in Toronto, Canada. “Until now, most scientists thought individuals with autism shared common genes. We now think each person has his own rare variations.”
  • If significant CNVs show up, behavioral treatment can be started early. That has been shown to improve children’s outcomes significantly. “If we provide stimulation early, while the brain is still plastic, we can improve cognitive development, social interaction and communication,” says Geri Dawson, Chief Science Officer of Autism Speaks, the major sponsor of the research project.
  • What this new research suggests is that autism and ASD probably result from the interaction between many different genes and a child’s environment. Rather than search for one single cause and one “magic bullet,” researchers will try to find as many significant genetic variants as possible, link them to the biological functions and pathways they control, and then search for medications that can improve or normalize the functioning of damaged pathways.

Research Unearths New Treatments for Autism - 2 views

  • The Utah researchers found that children receiving a combination of the two treatments (Lovaas-type training at school and TEACCH methods at home) showed three to four times greater progress on all outcome tests than did children who received only the school-based treatment. That study was reported in the Journal of Autism and Developmental Disorders (Vol. 28, No. 1, p. 2532).
  • Researchers in Washington, D.C., are comparing a discrete trial training approach with a "developmental, individual-difference, relationship based" (DIR) approach, says child psychiatrist Stanley Greenspan, MD, professor of psychiatry at George Washington University Medical School.
  • Psychologist Robert Koegel, PhD, at the University of California, Santa Barbara, and his colleagues are attempting to tailor a standard treatment to the specific needs of an autistic child and family. The standard treatment is called pivotal response training
  • ...5 more annotations...
  • An initial retrospective study is comparing two groups of 20 children initially diagnosed with autism who were functioning well after two or more years of treatment, either with a discrete trial training approach or the DIR approach. The study aims to determine if treatment differences lead to subtle differences in outcome, for example, in terms of flexibility, emotional range, creativity and richness of the child's inner life. Investigators are planning to follow this research with a prospective, randomized, more rigorous study of the two approaches.
  • "In our previous studies we found out that it looks like you can't just deliver a standard treatment to autistic kids, that there's so much variability among the children that what works for one child doesn't work for another child," he says. "Our hypothesis is that...unless you individualize treatment, you're not going to get the best effect."
  • Researchers at the University of Maryland are testing an intervention to trigger children's "social engagement system," which includes behaviors such as listening, looking, facial expressions and vocalizations that support social interaction, says psychologist Stephen Porges, PhD. The treatment is designed to improve autistic children's ability to interact with others, thereby making them more receptive to traditional therapies.
  • The intervention is based on the theory that tensing the middle ear muscles enables people to pick out the human voice from lower frequency sounds in the environment, Porges says. Treatment involves exercising middle ear muscles by playing music that has been altered to include only frequencies associated with the human voice, which improves one's ability to listen to human voices. This, in turn, stimulates the entire social engagement system, Porges says. About 80 percent of 50 children with autism or other behavioral problems receiving this treatment via five 45-minute sessions in a double blind, randomized controlled study showed marked improvements in listening, language and other communication skills.
  • In a report last year in the Journal of Autism and Developmental Disorders (Vol. 28, No. 1, p. 15-23) evaluating an intensive home-based discrete trial training intervention, Stephen Sheinkopf, PhD, of the University of Miami and Bryna Siegel, PhD, of the University of California, San Francisco, noted that children receiving an average of only 21 hours per week of treatment showed gains in IQ comparable to those achieved by children receiving 32 hours per week. The intensity question remains an issue of importance for the autism community. "If we need 40 hours a week, fine," says psychologist Geraldine Dawson, PhD, of the University of Washington. "But if you only need 25, you have to realize that 40 hours is a tremendous burden not only financially, but on families and on the child."
  •  
    Several treatments, and combinations of treatments, are under intense study.
